A boss is a powerful, usually unique monster that is fought to accomplish an objective, be it the advancement or completion of a quest or minigame or as part of a team player versus monster event. Many quests feature boss fights at their climaxes; such bosses are often the main antagonists of the quests or quest series or are somehow related to the main antagonist(s).
Some monsters that are commonly referred to as bosses are very powerful monsters that are commonly fought by teams of players in search of highly valuable drops. Many bosses have extremely high combat levels, and all of the strongest monsters in the game are bosses. Bosses are typically immune to a combination of either stun, poison, or reflect damage. Even fewer bosses are immune to a combination of leeching effects (from the Ancient Curses) or status abnormalities (defence drain (not affinity value) or damage increasing hexes), generally recovering from the latter very quickly.
Dwarf multicannons often cannot be set up in the areas of many bosses. Others may have different restrictions; for example, only black equipment may be used to fight the tormented wraith, and Prayer cannot be used during the fights with the final bosses of Recipe for Disaster.
Since the introduction of Kerapac, the bound, all updates that introduce new bosses to the game start a week-long event where Death provides free item reclaims and a ring of death doesn't lose charge upon dying. The event ends at noon seven days after the update that introduces the boss.
PvM bosses[edit | edit source]
Independent high-level bosses[edit | edit source]
These are the most powerful bosses that do not share a lair or dungeon with other bosses. These are amongst the most powerful creatures in RuneScape, and some require a team to be killed.

|Vorago||10,000||Vorago is an enormous and powerful being born from Gielinor's anima mundi. He used to wreak havoc in the past, before he was vanquished by the maul of omens and fell into a long slumber to regain his strength. He re-awakened in the Sixth Age, although he became much more affable to adventurers, instead requesting challenges in combat to prepare himself to combat the threat of gods on Gielinor. Indeed, Vorago is a mighty adversary in combat, with multiple attacks and tactics at his disposal that change weekly to provide a varied fight for players. The fight stresses teamwork between players, as Vorago has many mechanics that require coordination within a team to handle properly. Vorago drops the Seismic wand, Seismic singularity, dual-wielded level 90 Magic weapons, and Tectonic energy, which is used to make Tectonic armour with level 91+ Runecrafting, tier 90 magic power armour.||Melee

|Solak||7,000||Solak, the Grove Guardian, is an anima being known as a walker, who was tasked by Guthix to protect The Lost Grove from those who would try to use its power. By the time of the Sixth Age, he had fallen under the control of an elf named Erethdor, who had succeeded in almost completely taking over Solak's mind. With Solak's power now at his disposal, Erethdor uses the full extent of the grove guardian's arsenal against his opponents, many of which inflict unique blight damage. Players fight alongside Merethiel, Erethdor's sister, in an intended group size of between 2-7 players to remove his hold over Solak. He is considered to be one of the most challenging group bosses, in part due to his mechanics being very punishing to the entire group if even one player makes a mistake. Upon destroying Erethdor for good and freeing Solak from his control, Merethiel will reward each of her champions with valuable loot; most notably the Blightbound crossbow and its off-hand variant, dual-wielded level 92 Ranged weapons, and Erethdor's grimoire, a powerful pocket slot item. Merethiel can also reward players with cosmetic unlock items for her stave and the blightbound lasher pet. She may also rarely reward players with a pair of cinderbane gloves or an ancient elven ritual shard.||Melee

|Barrows - Rise of the Six||650 x 6||Barrows - Rise of the Six is an upgraded version of the original Barrows minigame. Players fight the six Barrows brothers simultaneously, with three brothers on two sides separated by a shadow portal in the middle of a single room. They have been empowered by Sliske's experiments in the Shadow Realm. The brothers are massively enhanced and in terms of difficulty, on par with Vorago. If all brothers are killed, the chest can be looted. Possible loots include level 90 shields and Malevolent energy, which is used to make Malevolent armour, tier 90 melee power armour, with level 91+ Smithing.||Magic

|Araxxor and Araxxi||2,500 and 3,000||Araxxor is a large araxyte spider found in the Araxyte Hive, along with its mate Araxxi; both of whom are feared by the vampyres. Players can "customise" the fight by taking different paths, which change every 4 days. Araxxor fights primarily with one of the three styles of combat per encounter at random, or forced to use the style weak to the player if an Araxyte pheromone is carried in the inventory. It is a fight to the death, as there is no way to leave upon entering the den and players cannot teleport out of the hive until Araxxi is defeated. Boasting a large variety of mechanics, they also have an enrage mechanic where consecutive kills and certain mechanics cause Araxxor and Araxxi's enrage to increase, capping at 300%, which increases the damage of their regular attacks and special attacks. However, the enrage will reset back to 0% at the start of each day, or if an Araxyte pheromone is released. Araxxi drops components of the Noxious weaponry, level 90 two-handed weapons.||Magic

|Kalphite King||2,500||The Kalphite King is the king of the exiled kalphites, found in the Exiled Kalphite Hive south-east of the Bandit Camp Lodestone in the desert. One of the first bosses to utilise the mechanics of the Evolution of Combat, the Kalphite King utilises many abilities and mechanics, including charging, digging, and one-hit attacks. He is also able to change his attack style and weakness throughout the fight, using different abilities with each style. It is known for dropping Drygore weaponry, level 90 main and off-hand melee weapons in three styles: maces, rapiers and longswords, along with the perfect chitin, an item required to create level 90 defenders.||Magic
|Kalphites||14 January 2013|
|WildyWyrm||1,337||The WildyWyrm may occasionally spawn in place of a regular lava strykewyrm. They can wander across the whole Wilderness and share the same attack mechanics as regular lava strykewyrms, albeit being far more powerful than their normal counterparts. It shares their unique drops, the wyrm heart, wyrm spike and wyrm scalp with their cousins but with a better drop rate. All players who participate in defeating the WildyWyrm will receive their own loot, however only one player can receive a unique drop per kill.||Melee
|Lava strykewyrms||21 February 2011|
|Queen Black Dragon||900||The Queen Black Dragon is the first dragon ever created by Kerapac. She is located in the deepest sector of the Grotworm Lair, requiring 60 Summoning to face her. She can only be fought alone, and attacks her opponents with a multitude of special attacks and extremely potent dragonfire, necessitating the use of an anti-dragon shield or super antifire potions in order to withstand it. She is fought in four stages; at the end of each the player must activate an artefact. The Queen Black Dragon cannot be killed; instead, once the fourth artefact is activated, she will return back into her slumber and the fight will end, allowing the player to enter the rewards room and open the coffer. In addition her generous normal rewards, she also drops the rare Dragon kiteshield drop, Dragonbone Upgrade Kit, and pieces of the Royal crossbow. As she is a black dragon, she can also drop a draconic visage and black dragon eggs for the Player-owned farm.||Melee

|Corporeal Beast||785||The Corporeal Beast is the physical incarnation of the Spirit Beast, which was brought into existence as an opposite consequence of the destruction of the spirit beast in the spirit realm, and may be fought after completion of Summer's End. With a combat level of 785, the Corporeal Beast is not meant to be taken lightly. It boasts very strong attacks, high defence, and a 50% reduction to damage from all weapons except spears. It also has the unique ability to consume summoning familiars, preventing players from using a combat familiar or beast of burden to aid them. Those who are able to vanquish the beast may rewarded with a spirit shield or a holy elixir to create its blessed variant. The Corporeal Beast is more notably the only monster that drops sigils for upgrading a blessed spirit shield into a spectral, divine, elysian or arcane spirit shield. With the exception of the spectral spirit shield, these shields provide damage shaving effects at the cost of Prayer.||Melee

|The Magister||899||Oreb the Magister is Nomad's former master who has now found his way to the Sophanem Slayer Dungeon, awaiting the player at the First Gate of the Grim Underworld. Requiring level 115 Slayer to defeat, the Magister is a powerful adversary that utilises the corruption mechanic found within the Sophanem Slayer Dungeon, and also has the ability to drain the player's Constitution level, thereby decreasing their maximum lifepoints and the amount restored from food. He must be fought alone, and one Key to the Crossing must be sacrificed per fight. His most notable drop is phylactery, which can be shattered to obtain scraps of scripture used to create blessings. These blessings can be used to upgrade the Khopesh of the Kharidian and its off-hand into the Khopesh of Tumeken and Elidinis, which are tier 92 dual-wielded melee weapons. The Magister also drops the unique gloves of passage, which are tier 85 melee power gloves that increase the next ability's damage by 7% after Havoc is used.||Melee Magic Ranged||Soul devourers (Slayer helmet does not work)||3 July 2017|
|Raksha, the Shadow Colossus||6,000||Raksha is an ancient rex dinosaur turned into a shadow colossus following an encounter with the Codex. He was inadvertently brought forward to the present time by Kerapac alongside the rest of Anachronia using the Needle and reawakened from his coma due Kerapac's generation of shadow anima. Under the direction of Raksha's custodian, The Keeper, players may fight the shadow colossus in a solo or duo instance. Raksha fights with slow but powerful attacks from all three styles of combat, necessitating frequent prayer switching throughout the fight in order to survive and deal with his other mechanics. Upon defeating Raksha, The Keeper may reward players with ability codices for unlocking the Divert ability and the greater versions of Ricochet and Chain. The Keeper can also award laceration boots or blast diffusion boots, which are otherwise obtained from slayer creatures on Anachronia, or the unique fleeting boots which are exclusively obtained from defeating Raksha. Finally, The Keeper can award shadow spikes, which can be used to upgrade any of the three aforementioned boots to their enhanced variants, increasing them from tier 80 to tier 90.||Melee Magic Ranged||N/A||7 December 2020|
God Wars Dungeon[edit | edit source]
For each warring deity in the God Wars Dungeon, there is a very powerful leader commonly referred to as a "general". Each general also has three bodyguards, one of which uses each style of combat: Melee, Magic, and Ranged (with the exception of Nex, who has four bodyguards and all of them use magic). In addition to the 60 Strength or 60 Agility required to enter the God Wars Dungeon, each general's encampment has further requirements to enter.
Nex drops tier 80 armour and weaponry, Nex (Angel of Death) drops tier 92 weaponry and tier 99 prayers, and the generals drop tier 70 armour and tier 75 weaponry. Apart from Nex, each of these generals also has a unique hilt to make their version of the Godsword, which has various effects.

|Nex: Angel of Death||7,000||70 Ranged
||Infused with ancient power from her own creation, Nex: Angel of Death is the upgraded boss encounter with Nex. Players will find they must co-operate as a team to bring her down, though Players who bring her down are immensely rewarded, and have a chance of obtaining valuable rewards such as the Wand of the praesul and the imperium core, dual wielded tier 92 magic weaponry, the Praesul codex, which unlocks level 99 curses, and four different cosmetic chests. Up to 50 players can face her at once, however groups of 7 or less players have a better chance of receiving her more valuable rewards.||Magic

||Nex is the leader of the Zarosian army trapped within the God Wars Dungeon by the forces of Saradomin, Zamorak, Bandos and Armadyl. She has a number of immensely powerful attacks in her arsenal, some of which can hit up to 6848 damage. Rather than following the trend of other God Wars Dungeon bosses and having three bodyguards, Nex is assisted by four mages, each of which represents one of the elements of the Ancient Magicks. Reaching her requires assembling a key to bypass the frozen door, the four pieces of which may be dropped within the monsters of the Saradominist, Zamorakian, Bandosian and Armadylean encampments. Thus, Nex effectively has all of the requirements of the other God Wars Dungeon bosses to reach. Nex drops many unique items: Torva armour, Pernix armour, and Virtus armour, which are three full sets of power armour, and the Virtus wand, Virtus book, and zaryte bow. Her minions and bodyguards drop ancient ceremonial robes.||Magic

He can occasionally use a special ability dealing massive typeless damage to his target and draining their prayer points by half. His bodyguards are the demons Tstanon Karlak, Zakl'n Gritch and Balfrug Kreeyath. He drops the Zamorak hilt, and he and his bodyguards also drop the robes of subjugation, Zamorakian spear, and steam battlestaff.||Magic

|Commander Zilyana||596||70 Agility||Commander Zilyana is the level 596 Icyene general of Saradomin, attacking rapidly and accurately with both Melee and Magic. Players should avoid using blood spells against Zilyana, as their continued use will cause her to become enraged, increasing her attack power considerably and making her much more dangerous. Her bodyguards are Starlight, Growler and Bree. She drops the Saradomin hilt, and she and her bodyguards drop the Saradomin sword, Armadyl crossbow, and amulets of Saradomin.||Magic
|N/A||28 August 2007|

Heart of Gielinor[edit | edit source]
Heart of Gielinor, the sequel to God Wars Dungeon, is set in the Sixth Age. Like God Wars Dungeon, it also features four warring factions, each with a unique and powerful boss. The warring factions are the armies of Sliske, Zamorak, Zaros, and Seren — the four entities from Freneskae. Similarly to the God Wars Dungeon, each faction requires a specific skill requirement to enter which requires level 80 in their respective skill.
With the exception of Telos, all the generals drop Dormant anima armour, which can be powered with a god crest (obtained from killing the bosses) to create level 80 power armour, which can be upgraded into level 85 by using essences, which are also dropped by the bosses. They also drop unique level 85 weaponry, which has the power of a level 80 weapon but the accuracy of a level 90 weapon.
|Name||Level||Entry Requirement||Description||Attack Style||Release date|
|Telos, the Warden||2,000||80 Magic
||Telos is an anima knight created by the Elder Gods and born from the anima in the Heart of Gielinor, acting as a fail-safe to defend it from those deemed a threat. However, Soothsayer Sybil realised that Telos is only interested in defending the Heart, and could be a threat to the rest of Gielinor's inhabitants. Thus, she has tasked the World Guardian with dealing with Telos before it becomes too powerful. Telos has four (or five if enrage is over 100%) different phases where both the player and Telos descend deeper into the Heart as the fight progresses. Telos uses both melee and magic, in addition to having unique abilities in each phase reminiscent of the warring generals above him. Telos has a unique risk-reward system where players have the option to either claim their loot or put it on the line and increase Telos's enrage. Telos gains increased damage output and new mechanics as his enrage climbs. Should the player die, a significant portion of their loot will be lost and the streak will be ended, but the longer a player can continue a successful kill-streak, the more lucrative the rewards become. Telos's enrage can increase up to a maximum of 4,000%, however reaching higher enrages requires immense dedication and complete mastery of the boss fight, providing a significant combat challenge for even the most skilled players. Telos drops level 92 dormant god weaponry, which are powered by three different orbs that he also drops to craft the Zaros godsword, Seren godbow and staff of Sliske. In addition to this, he also drops a codex that unlocks the Reprisal ability, a level 85 Constitution ability which damages the target for the same amount of damage the user receives.||
|27 June 2016|
|Gregorovic||1,000||80 Prayer||Gregorovic is the general of Sliske's army. Once a human, desperately trying to fight death, he eventually sold his soul to Sliske in return for eternal life. Gregorovic uses a combination of Ranged and Melee attacks. His attacks are extremely poisonous, which makes using countermeasures a requirement. He has the ability to summon spirits which will increase the potency of his attacks; during the fight, he will also spawn two weak clones of himself. Gregorovic drops the Crest of Sliske, which can be combined with Anima Core equipment, the Shadow glaive level 85 thrown weaponry, as well as several useful items.||Ranged
|7 March 2016|
|Twin Furies||1,000 x 2||80 Ranged||The Twin Furies — Nymora, the Vengeful and Avaryss, the Unceasing are the Zamorakian generals in the Heart of Gielinor. They are Avernic demons who have been in Zamorakian service since the God Wars. The player simultaneously fights both Nymora and Amaryss, thus needing to expect damage from two sides. The furies, however, share their health pool, so abilities attacks that hit multiple targets are much more potent against them. Nymora mainly uses Ranged attacks, while Avaryss focuses on Melee. They also use several special attacks involving their environment. They drop Blade of Avaryss and Blade of Nymora, level 85 swords, and the Crest of Zamorak, as well as many general useful items.||

|Vindicta||1,000||80 Attack||Vindicta is the level 1,000 Zarosian general in the Heart of Gielinor. She is a Dragon Rider, daughter of Morvannon and Hannibus, who grew up in the Grotworm Lair and is now seeking to avenge the murder of Morvannon. She is accompanied in the fight by her mount, Gorvek. Vindicta's auto-attacks hit very hard, her mount Gorvek will also use dragonfire in the fight. Halfway through the fight, Vindicta will mount Gorvek and the two will fight together. Vindicta drops the Dragon Rider lance, the Crest of Zaros and various general items.||Melee||7 March 2016|
|Helwyr||1,000||80 Magic||Helwyr is the Seren general in the Heart of Gielinor and a member of the Cywir Clan of the elves. He has taken on the form of a large predator he slew while on Tarddiad. He will also summon mushrooms in his arena which puff out a stunning and damaging gas, he can call Cywir alphas to his aid, and can also cause typeless damage bleeds that worsen the more bleeds players sustain until they are cleared using Freedom. Helwyr drops the wand and orb of cywir elders, dual-wielded magic weapons, the Crest of Seren and various general items.||Melee||7 March 2016|
Elder God Wars Dungeon[edit | edit source]
Located within an intact portion of the city of Senntisten, the Elder God Wars Dungeon follows the narrative continued from the City of Senntisten quest. With the player's help, Azzanadra has moved the eggs of the Elder Gods to a cathedral within the city, where Armadyl, Zamorak, Saradomin and Seren are attempted to draw out their anima to prevent them from hatching. In response, the four Elder Gods–Jas, Ful, Wen and Bik–have sent their forces to reclaim their eggs, and if they succeed, they will most likely precipitate The Great Revision, destroying the entire universe.
Unlike the previous two God Wars Dungeons, the four "fronts" of the Elder God Wars Dungeon were not made available all at once. Instead, they were released in monthly updates starting with Jas' army, the Nodon Front, and ending with Ful's army, the TzekHaar Front. The dungeon also differs by having no killcount or skill requirements to face the bosses within, and the generals each offer a different style of combat challenge.

|Kerapac, the bound||3,000||Enslaved by Jas once again and driven by the pain of the curse, Kerapac has been forced to lead an army of Nodon dragonkin to reclaim the eggs of the Elder gods. With The Needle at his side and wielding the legendary Staff of Armadyl, he uses both Elder Artefacts to destroy anyone who opposes him, using the staff to launch devastating magic attacks at his targets and The Needle to reverse time and prevent his own defeat. Kerapac is a 4-phase boss and can be fought in groups of 1-3 players, retaining the same amount of lifepoints and rewarding the same total amount of loot for any group size. Players who face him will also be granted the unique "time warp" ability, which records their position, life points and ability cooldowns and returns to these values 10 seconds later. In addition to a normal mode, Kerapac has a hard mode which increases his total life points, alters some of his mechanics, and completely changes the fourth phase, making the fight far more challenging. Players who defeat Kerapac may receive an ability codex to upgrade Concentrated Blast to its greater variant, a Scripture of Jas that serves as a strong pocket slot item, Manuscripts of Jas to charge the scripture, or his wrist wraps, which affect the Dragon Breath and Combust abilities. Exclusively in hard mode, Kerapac may also drop the symbol, gem or shaft of the Fractured Staff of Armadyl, a very powerful tier 95 staff with a special attack that launches extra spells every time a critical hit occurs.||
|Nodon dragonkin||26 July 2021|
|Arch-Glacor||7,000||Hailing from the frigid world of Leng, this monstrous glacor was brought to the city of Senntisten alongside its smaller kin by Wen to aid their effort to reclaim the Elder god eggs. The fight with the Arch-Glacor can be customised by speaking to various mages keeping the creature's powers in check, allowing mechanics to be toggled on or off depending on the player's preference. Enabling more mechanics will make the fight more difficult overall, but will also increase the rewards appropriately. In normal mode, dying is treated as a safe death, and there is no restriction to the number of players that can take on the Arch-Glacor at once. However, players who can defeat the Arch-Glacor with all mechanics enabled in a solo encounter will gain access to hard mode. In hard mode, the Arch-Glacor must be fought alone in a similar manner to Telos, where loot is obtained in a streaking system, enrage increases with consecutive kills, and it is no longer possible to teleport out until the Arch-Glacor is defeated. Rewards for defeating the Arch-Glacor include dark nilas, which is used to craft various items including the dark ice shard and dark ice sliver: tier 85 dual-wield melee weapons that allow the use of Hurricane. It can also drop a Scripture of Wen that serves as a strong multi-target pocket slot item, and a Leng artefact which are used to enhance gloves of passage, Kerapac's wrist wraps and nightmare gauntlets, increasing them from tier 85 to tier 90. Finally, exclusively in hard mode, it can drop a Frozen Core of Leng, which is used to upgrade the dark ice shard and sliver to the Dark Shard of Leng and Dark Sliver of Leng, respectively. This increases them to tier 95, and adds a special attack which increases the damage cap of melee attacks by 30% for 30 seconds.||

|Croesus||6,000||Croesus is a sentient, highly dangerous fungus that invaded the city of Senntisten over 7,000 years ago before it fell into a dormant state beneath the city's graveyard. Bik found and revived Croesus, taking control of the organism to attack the cathedral and reclaim the Elder god eggs. Now, Gorvek has recruited the World Guardian and fellow adventurers to fight back against the creature. Unlike other bosses, Croesus is a skilling boss that is fought using non-combat skills, specifically Hunter, Mining, Fishing and Woodcutting. The goal of the battle is to use these skills to collect fungus growing on large creatures and fallen guards to restore four different statues around the graveyard. Once restored, the statues can be prayed to in order to awaken the spirits of great heroes of the Second Age, subduing Croesus and exposing its core, giving the combatants an opening to damage the creature. Instead of doing damage, Croesus' attacks drain the player's stats. If player's stats are drained too much, they will be forced out of the encounter. In addition, the encounter will end early if Croesus' meter reaches 100%, or if the party fails to destroy Croesus' core after praying to all four statues. However, if the core is defeated, each player in the party will be rewarded based on their contribution to the kill. Possible rewards include incomplete pieces of the Cryptbloom armour, a set of tier 90 magic tank armour with unique set effects; the Scripture of Bik, which can give experience bonuses and clue scrolls while skilling when active; the Croesus sporehammer and Croesus foultorch, used to create the Tagga's corehammer and Sana's fyrtorch off-hand items, providing benefits to mining and woodcutting respectively; and a Croesus spore sack, which is used to create the seed bag for storing 40 different types of seeds.||N/A||N/A||27 September 2021|
|TzKal-Zuk||14,000||Zuk, Champion of the Fire, is a former human gladiator who ascended and became a demigod warlord after becoming the first outsider in history to best the TokHaar, claiming the Elder Kiln itself as his prize. Ful has reforged the TokHaar into the battle-hearted TzekHaar to reclaim her egg, choosing TzKal-Zuk to lead her army. Similar to the TzHaar Fight Caves and Fight Kiln, players who challenge Zuk must fight alone against waves of TzekHaar first, including alternative versions of Jad and Har-Aken. At the end of his gauntlet, TzKal-Zuk will face you himself, demonstrating his exceptional power. His arsenal includes powerful melee and magic attacks, the ability to inflict Geothermal Burns, draining the player's constitution level, area denial, and one-hit attacks that must be intercepted. Players who succeed in all three of Zuk's mini challenges and defeat him in a single run without dying will gain access to hard mode, where the TzekHaar are even stronger and only one checkpoint is permitted right before the fight with Zuk. Rewards for defeating Zuk in both modes include the Magma Tempest ability codex, which unlocks a level 66 two-handed Magic ability which damages enemies in a 5x5 area; and the Scripture of Ful, a pocket slot item which increases damage dealt and damage received for 15 seconds when it activates. Exclusively in hard mode, players may obtain either the blade, core or hilt of the Ek-ZekKil: a tier 95 two-handed melee weapon with a special attack that places a burning bleed on a target which can be extended by other bleeds. Those who defeat Zuk without dying or using any checkpoints will receive an igneous stone, which can be combined with the TokHaar-Kal capes from the Fight Kiln to make the igneous Kal-Ket, igneous Kal-Mej and igneous Kal-Xil. These upgraded capes are the strongest capes available for their respective style, and they bolster the Overpower, Omnipower and Deadshot abilities, respectively. Finally, players who manage to complete hard mode flawlessly will earn the right to combine all three igneous capes together to form the igneous Kal-Zuk, an all-class cape that combines the style bonuses and passive effects of all three igneous capes.||

Elite Dungeons[edit | edit source]
The three elite dungeons - the Temple of Aminishi, Dragonkin Laboratory, and The Shadow Reef have three bosses in each dungeon. The Zamorakian Undercity only has one boss, although there are required mini-bosses to be cleared if the dungeon is entered normally. Each boss is fought in order as the player(s) progress deeper into the dungeon.
Temple of Aminishi[edit | edit source]
|Name||Level||Description||Attack Style||Release date|
|The Sanctum Guardian||850||A massive Crassian sent to the Temple of Aminishi to guard the inner sanctum from outsiders and curious acolytes alike. Her ranged attack is a targeted, 3x3 AoE attack that can be avoided by running away from the spot the projectile was fired at. She also uses the pool she resides in to collect water and unleash a powerful blast that can severely damage players hit by them, and finally exhale corrupted energy which proves fatal if stood in the longer it persists. She is also able to expel a large torrent of water in an anticlockwise direction around her arena, severely damaging any players who get caught in the deluge. She usually drops onyx dust, but may occasionally drop a fishy treat instead, which is an item that can be used on her to automatically skip the fight.||

|Masuta the Ascended||1,000||One of the members of the Council of Seven who is an extremely powerful warrior after numerous years of training. He has many attacks at his disposal, all of which are extremely dangerous if not avoided or dealt with. He has three "phases"; the first phase initiating simple combat where he can create clones to attack players, spin and deal gradually increasing damage and unleash barrages of corrupted energy. In the second phase, he summons numerous thrashing waters to attack the player, and in the final phase, he solely focuses on ranged attacks and his corrupted energy meteor strike attack. He usually drops onyx dust, but may occasionally drop his warspear instead, which is a level 82 halberd-type spear weapon.||

|Seiryu the Azure Serpent||10,000||One of the four guardians of the Wushanko Isles, it is considered the purest by the Acolytes of Seiryu, who worship it. However, the order was soon led astray and instead restrained Seiryu, subjecting it to black crystals and slowly corrupting it. Seiryu is the final boss of the Temple of Aminishi, and has numerous attacks which can be fatal if carelessly dealt with. As players knock Seiryu out of commission, they must destroy the three black crystals on the collar restraining him to free him of the corrupting influence. Seiryu then rewards players as he is finally free with ancient scales, which can be used to upgrade the level 90 sirenic armour to its elite variant, which is level 92.||

The Zamorakian Undercity[edit | edit source]
|Name||Level||Description||Attack Style||Release date|
|Zamorak, Lord of Chaos||10,000||Zamorak, following the events of the Elder God Wars storyline, began his own invasion of Gielinor with an army of demons and newly acquired supporters to his cause, having fortified himself in the Wilderness Crater with an impenetrable barrier. Players must initially clear his corresponding elite dungeon, the Zamorakian Undercity before they can face Zamorak; having cleared it enough times or reaching a specific enrage allows players to completely bypass the dungeon and face him instead. Unlike the other final bosses of elite dungeons, Zamorak utilises an enrage system. During the encounter, the player will attempt to re-establish the Edicts of Guthix in order to dispel Zamorak from Gielinor, who will likewise try to stop them with his new powers. Players who are successful in defeating Zamorak will be rewarded appropriately for their efforts, such as Vestments of havoc armour, tier 95 melee armour with strength bonus equal to tier 100 and armour to 75, the codex of lost knowledge, allowing players to create codices for Greater Sunshine and Greater Death's Swiftness, a Chaos Roar ability codex that allows the player's next attack to deal double damage, and parts of the Bow of the Last Guardian, a tier 95 bow.||4 July 2022|

Rex Matriarchs[edit | edit source]
The Rex Matriarchs are three powerful female rex dinosaurs that were enhanced by Kerapac by the addition of various traits grafted from Raksha. Their lair is located in the Spirit Grove on Anachronia, which can be accessed via a teleportation device on the east side of the grove. At level 888, they are considered to be the spiritual successors of the Dagannoth Kings and share many similarities, however, the Rex Matriarchs possess unique mechanics, attack with two different combat styles each, and have extremely high resistance to combat styles they are not weak to instead of complete immunity. Like Raksha and unlike the other dinosaurs on Anachronia, they have no slayer requirement to be fought. However, the Rex Matriarchs count for dinosaur slayer tasks.
All three dinosaurs drop four different pieces of Laniakea's spear, a tier 82 halberd-range spear with tier 75 accuracy and tier 90 damage that is inherently poisonous and boosts poison damage by 5%. They also drop hearts which can be combined with 10 of each of the rings dropped by the Dagannoth Kings to form much stronger rings with passive effects. All three can drop the Heart of the Berserker, which can be combined with 10 berserker rings to create the reaver's ring, a hybrid ring that boosts critical strike chance by +5% at the cost of -5% to hit chance. The other three hearts are dropped exclusively by specific dinosaurs. They are also able to drop unchecked eggs for the Anachronia Dinosaur Farm.
|Name||Description||Attack Style||Release date|
|Rathis||Rathis is the ranged Rex Matriarch, and is weak to stabbing attacks. She primarily attacks with ranged by launching spines, but will occasionally attack with melee by ramming her target. Her special ability involves lobbing two poison orbs into the air, which land and cause high ranged damage to anyone in the vicinity while leaving a large pool of poison on the ground. Players standing in these pools will absorb the poisonous liquid, dealing rapid poison damage which can be mitigated through poison immunity. This poison inflicts a "Corrosion" debuff that temporarily increases the damage her target takes. Eventually, Rathis will reabsorb any leftover poison on the ground to heal herself. In addition to parts of Laniakea's spear and the Heart of the Berserker, Rathis exclusively drops the Heart of the Archer. This can be combined with 10 archer's rings to create the stalker's ring, a ranged ring that provides +3% critical strike chance when using bows. Rathis can occasionally drop an unchecked corbicula rex egg as well.||Ranged
|19 April 2021|
|Pthentraken||Pthentraken is the magic Rax Matriarch, and is weak to arrows. She primarily attacks with magic by firing balls of lightning, but will occasionally attack with ranged by lobbing a boulder at her target. Pthentraken's regular attacks are much more damaging compared to the other two Rex Matriarchs, making her more dangerous to fight. Her first special ability involves summoning four lines of lightning that deal massive magic damage to anyone caught in their path, however, the damage can be drastically reduced by wearing insulated boots. The other ability involves an overhead timer on her target, which momentarily causes a geyser of energy to erupt from them. Standing in the geyser deals heavy typeless damage, but also grants an "Overcharged" buff for 30 seconds which allows for unlimited use of Surge. In addition to parts of Laniakea's spear and the Heart of the Berserker, Pthentraken exclusively drops the Heart of the Seer. This can be combined with 10 seers' rings to create the channeller's ring, a magic ring that provides +4% critical strike chance per hit of channelled abilities. Pthentraken can occasionally drop an unchecked pavosaurus rex egg as well.||Magic
|19 April 2021|
|Orikalka||Orikalka is the melee Rex Matriarch, and is weak to fire spells. She primarily attacks with melee by biting her target, but will occasionally attack with magic by expelling icy breath. Her first special attack involves launching freezing orbs at all nearby targets that deal high magic damage and inflict a "Frostbite" debuff, which drains run energy and halves the speed that players can use abilities for 30 seconds. Her second ability involves causing multiple fissures to open around her, dealing massive melee damage before erupting. Players with the Frostbite debuff that stand in the eruptions will "thaw out" and have the effect removed, gaining a huge surge of adrenaline instead. In addition to parts of Laniakea's spear and the Heart of the Berserker, Orikalka exclusively drops the Heart of the Warrior. This can be combined with 10 warrior rings to create the champion's ring, a melee ring that provides +3% critical strike chance against bleeding targets. Orikalka can occasionally drop an unchecked bagrada rex egg as well.||Melee

|Name||Description||Attack Style||Release date|
|Dagannoth Supreme||Dagannoth Supreme is the ranged Dagannoth King, and therefore is weak to stabbing attacks.

He is the only King to drop Spined armour, Archers' rings and the Seercull.||Ranged||7 November 2005|
|Dagannoth Prime||Dagannoth Prime is the magic Dagannoth King, and therefore is weak to arrows.

He is the only King to drop Skeletal armour, Seers' rings and mud battlestaves.||Magic||7 November 2005|
|Dagannoth Rex||Dagannoth Rex is the Melee Dagannoth King, and therefore is weak to fire. Due to lacking long-ranged attacks, he can be safe-spotted quite easily near the edge of the arena. He is the only King to drop Rock-shell armour, Warrior rings and Berserker rings.||Melee||7 November 2005|

Liberation of Mazcab[edit | edit source]
|Name||Level||Description||Attack Style||Release date|
|Beastmaster Durzag||2,000||Beastmaster Durzag is the first boss of Liberation of Mazcab. Before fighting Durzag himself, the team will face airut, chargers, and his pet beast, Cormes. During the fight, Beastmaster Durzag calls two pets, Krar and Tuz, along with many Chargers to assist him throughout the fight. Beastmaster Durzag can be looted once every 48 hours for a chance of Achto Primeval, Tempest and Teralith equipment, along with a general Mazcab ability codex.

Minigame bosses[edit | edit source]
Bosses that are fought during a minigame.
|Name||Level||Minigame||Description||Attack style||Release date|
|Har-Aken||800||Fight Kiln||Har-Aken is the final boss of the Fight Kiln minigame, having a combat level of 800. It is the strongest of all lava creatures (TzHaar and TokHaar). It is an extremely large creature consisting of a single head and multiple tentacles, which either use Ranged or Magic. Har-Aken's head is submerged in the lava, but will occasionally surface above, and players should use this opportunity to severely wound or kill it before it dives back into the lava. Players who defeat Har-Aken can be given a TokHaar cape of their choice or an uncut onyx for their efforts.
An alternate version of Har-Aken known as TzekHaar-Aken is encountered in the TzekHaar Front, serving as the penultimate boss. Not only is it stronger than the original, but it also has the ability to bombard the player with lava which deals high damage, drains adrenaline and halves the rate which players gain adrenaline for a short time. TzekHaar-Aken kills contribute to a player's killcount for Har-Aken, and they are also capable of dropping the volcanic shard to unlock the boss pet.
|14 February 2012|
|TzTok-Jad||702||TzHaar Fight Cave||TzTok-Jad is the final boss of the TzHaar Fight Cave minigame. It is level 702 and is extremely dangerous as all of its attacks, which hit from every side of the combat triangle, can each deal up to 9000+ damage. Additionally, TzTok-Jad summons Yt-HurKot to rapidly heal it once it reaches half health. The reward for defeating TzTok-Jad is 16,064 tokkul and the much-coveted fire cape. Kuradal the Slayer master will sometimes assign the entirety of the TzHaar Fight Cave minigame as a Slayer assignment; under these circumstances, another reward for defeating TzTok-Jad is 25,000 Slayer experience.
Alternate versions of TzTok-Jad, known as TokHaar-Jad and TzekHaar-Jad, are encountered in the Fight Kiln and TzekHaar Front, respectively. Although they can hit harder, they are easier to defeat since they do not summon Yt-HurKot to heal themselves. However, they do contribute towards a player's killcount for TzTok-Jad.

Dominion Tower[edit | edit source]
On 1 November 2011, Jagex released the Dominion Tower, a minigame that allows players to fight bosses from quests they have completed. Players can fight up to 60 unique boss monsters from previous quests, including Nomad, the Pest Queen, Zenevivia, the Balance Elemental, and many others.
Dungeoneering bosses[edit | edit source]
At the end of each floor of Daemonheim is a powerful boss monster that must be defeated in order to complete the dungeon. The levels and strengths of these bosses vary according to a combination of factors, including the dungeon's size and complexity rating, but they will otherwise always have the same qualities. Kal'Ger the Warmonger is the strongest in Daemonheim.
Enrage[edit | edit source]
Enrage increases the damage dealt by the bosses, from both auto-attacks and special attacks.
Araxxor and Araxxi increase their enrage throughout the fight via various mechanics. After killing and looting Araxxi's corpse, the next fight with the pair will add an additional 20% enrage to the fight, stacking with every kill afterwards, capping at 300% (although additional enrage can still be obtained during the fight). Enrage also affects the drop rate of the araxyte pheromone and araxyte pet, although the latter is only affected by enrage gained during the fight. An araxyte pheromone can be broken to reset their enrage level back to 0%.
On 27 June 2016, another boss with enrage, Telos, the Warden, was released. Telos' enrage functions similarly to Araxxor and Araxxi's, but with additional functions. Although the auto-attack scaling is significantly weaker (as a 300% enrage Telos deals far less damage than Araxxi), the damage dealt from his special attacks scales significantly higher in response. Various mechanics are added and/or modified as his enrage increases (such as a final phase in encounters of 100% enrage and higher). The higher Telos' enrage is, the more likely a unique can be rolled, although streaks still play a higher role in the drop rate in most cases. Telos does not possess any mechanics that increase his enrage during the fight; this is only applied whenever the player continues their streak after each kill, with a 5-20% enrage stack accumulating to the current level of enrage.
While not technically enrage, Beastmaster Durzag, Yakamaru and Nex: Angel of Death also possess enrage-like mechanics in the form of stacks, although the latter also possesses a passive enrage mechanic throughout the fight. The Liberation of Mazcab bosses' enrage can cause increased damage; Durzag's stacks are applied on the target he is focused on, while Yakamaru's stacks are applied on anyone in front of it as it attacks; the former causes defensive resets, while the latter has a damage multiplier. These may be halved by using Freedom.
Nex's enrage stacks are only focused on the target she is on with successful melee attacks, causing defensive resets at 5, 10 and 15 successful hits. After gaining 15 stacks, each melee attack after that will reset defensives. These "stacks" are removed when she has not attacked her target with melee after 30 seconds if she does not use melee or they missed.
On 31 August 2021, the Arch-Glacor was released, with enrage and streak mechanics largely similar to those of Telos. Unlike Telos, the Arch-Glacor has no health cap, resulting in it possessing 3,300,000 health at 4000% enrage, the highest of any solo boss in game and is widely considered the hardest challenge outside of soloing team bosses. The only mechanic that initially changes with enrage is the addition of a Bolstered Glacyte at 250% enrage and higher. The next change comes in at 2500% and higher enrage, in which the health of the Icy Arms and glacytes begin to scale alongside the boss.
The Zamorakian Undercity is also intended to use an enrage system. Unlike other bosses, enrage is only gained in intervals of 10% after defeating Zamorak, Lord of Chaos. Enrage increases the health of most enemies inside, and will begin to add and/or replace enemies as needed. Zamorak himself also uses enrage, with a new phase introduced at 100%+ encounters and mechanics being modified after 500%+.
