Overview[edit | edit source]

Demon bosses sporadically appear throughout most of Gielinor every hour. Their appearance is indicated with an news broadcast on the player's message box if it has not been disabled. Their pre-arrival is indicated with an evil symbol on the ground; this will despawn the previous demon boss if it has not been defeated.

Where the demon boss appears is random. To access all locations, the player needs to have started Regicide, as one of the potential spawn locations is in Tirannwn.

After the symbol disappears, the demon boss will appear with fourteen minions; six imp heralds, four lesser demons and two black demons. The imp heralds possess 2,450 health, the lesser demons have 30,000 health and the black demons have 60,000 health.

The boss will start off with 200,000 health, but cannot be attacked. In order to attack them, its minions must be killed. It will siphon health from its lesser and black demon minions, healing 3,000 and 6,000 health at a time respectively. The imps are the only minions who can be attacked first; once killed, the demon will be forced to send its lesser demons. If the lesser demons are killed, then it has no choice but to send the black demons on them. Once the black demons are killed, the boss becomes attackable.

If the boss ends up siphoning all of its health from its minions, it can be immediately attacked without having to fight the imps.

Demon bosses use powerful melee and magic attacks, which are further strengthened if the player attempts to use prayers outside of Protect Item and blood spells. Demon bosses possess offensive stats of 99 Attack and Magic, along with 85 Defence. Despite their "Nothing" weakness, they are susceptible to Darklight and the inquisitor staff. They possess 65 magic, 55 melee and 45 range affinity. They are immune to poison and stun, but not to leech and reflect. They are also considered greater demons for the purpose of a slayer task.

The demon comes with a randomly generated name and prefix, two of these making each fight unique by itself. These also determine what titles it can potentially drop when killed.

In order to be eligible for drops, the player must deal more than 500 damage in a single hit, and before the boss falls below 40,000 health. The player must be in combat with the demon; if they leave combat, they will be ineligible for drops until they satisfy the drop requirement.

Demon bosses in the Wilderness provide extra drops compared to those in non-Wilderness locations. Multiple drops can be obtained if they are fought in small groups.

Name[edit | edit source]

A demon boss's name will contain both a prefix and a suffix title, which indicate how the boss will fight.

All "area of effect" abilities apply to the demon's area of effect: within 3 squares of the boss.

Prefix Effect Suffix Effect
General Accurate melee Blazing Magic damage over time
Executioner High damage Corrupting Poison area of effect
Castellan High defence Frostborn Stun area of effect
Deacon Multi-target magic Glorious Stun target
Infernal Magic damage over time area of effect
Obscured Stat drain area of effect
Pestilent Poison target
Rending Melee damage over time
Shattering Melee area of effect
Terrifying Bind and reduced adrenaline gain area of effect

Prefixes[edit | edit source]

This section covers effective strategies to use based on the boss's prefix. Keep in mind that this alone cannot decide the best strategy, as the demon's suffix will need to be taken into consideration.

General[edit | edit source]

Demons with the general title possess more accurate melee attacks than usual.

Executioner[edit | edit source]

Demons with the executioner title possess more damaging attacks than usual.

Castellan[edit | edit source]

Demons with the castellan title have possess more defence than usual.

Deacon[edit | edit source]

Demons with the deacon title have their magic attacks turned into AoE attacks with a 3x3 radius from their current target (2 tiles from center).

Suffixes[edit | edit source]

This section covers effective strategies to use based on the boss's suffix. Keep in mind that this alone cannot decide the best strategy, as the demon's prefix will need to be taken into consideration.

Blazing, Rending, Infernal[edit | edit source]

Demons with these titles will apply a very weak damage over time attack with every successful attack they land. The former two will apply their damage over time to the tank, while the latter will apply it as an area of effect, and thus it may be avoided by standing back away from the boss.

Overall, the damage is very minor and will be very insignificant compared to the main hit. This damage over time effect can be used to your advantage. Every hit will trigger abilities like Revenge, allowing you to maximise your damage output quickly, and Preparation, to get Resonance off of cooldown quickly. These small hits will also trigger resonance, so it will need to be activated at the last second to have the large hits activate the effect.

Corrupting, Pestilent[edit | edit source]

Demons with these titles have the ability to poison. The former is an area of effect that can be avoided by standing back from the demon. The latter is more dangerous, as the poison will stack high, allowing it to hit well over 1,600. Having several doses of antiposion++ or an item with the Venomblood perk is recommended for pestilent demons.

Frostborn, Glorious[edit | edit source]

Demons with these titles have the ability stun and bind players for 3 seconds. The former is applied as an area of effect, and it may be avoided by standing back from the boss. The latter applies only to the main target, and will only stun on a successful hit. Freedom and Anticipation are very important for staying in combat with the boss. Plan your attacks ahead so that you can be under these abilities' effects, having stun immunity during combo or channelled attacks. Care should be taken when using prayer, as being stunned before you can cast resonance or other defensive abilities may result in death. Prayers can be deactivated and familiar scrolls can be used (including healing aura) even under this stun.

Shattering[edit | edit source]

Demons with the shattering title have a melee attack that hits all players in front of them. This can be avoided by standing back from the demon.

Terrifying[edit | edit source]

Demons with the terrifying title can bind and reduce adrenaline gain by 50% in a 3x3 AoE from the main target.

Obscured[edit | edit source]

Demons with the obscured title can drain the stats of players within their area of effect. Players using overload potions or its variants can practically ignore this ability, as it will recover the stats extremely quickly. It is recommended to avoid using anything that isn't an overload against demons with this title, as they will be quickly removed due to its effect. Super restore is mandatory if fighting these demons to counter their stat drain.

General/DPS role[edit | edit source]

This section covers strategy that is important to all players, and also provides insight into strategy for players taking on a solely DPS-based role.

Style[edit | edit source]

Despite the demon bosses having no explicit weakness, they are actually the weakest towards magic, moderately weak to melee, and the most resistant to range. Therefore, magic or melee with Darklight is recommended. Melee is inherently less flexible than magic and ranged as it requires being adjacent to the boss. For demons with an area of effect ability, this is a large hindrance, and it may be preferable to use a different style; for demons without, melee can be equally effective for the fight. Overall, however, melee has a huge advantage with the darklight upgrade that can be purchased after Dimension of Disaster. With the upgrade, it is extremely easy to achieve near 100% accuracy, even without potions.

Equipment[edit | edit source]

No matter what your role is, accuracy and damage will be important. Players taking on DPS role should preferably be using superior Elite Void Knight equipment. If you do not have superior elite void, then power armour will be preferable over tank armour.

Beginning a fight[edit | edit source]

If you are present when the boss is freshly spawned, he will be surrounded by 6 imp heralds, 4 lesser demons, and 2 black demons. Unlike the common mob-type demons, these demons have significantly higher health.

The boss immediately starts siphoning health from the lesser demons, one at a time. If all the heralds are killed or he finishes off the lesser demons, the boss immediately starts siphoning from the black demons. The boss siphons health equal to 1/10th of his current target's health, so he heals 3,000 life points at a time from lesser demons, and 6,000 from black demons.

To interrupt the healing as fast as possible, kill all the imp heralds. This will prompt the boss to send his lesser demons at his assailants. Once all the lesser demons are killed, he will be forced to send his black demons at you.

Use of prayer[edit | edit source]

Except for protect item, all prayers and curses will greatly increase the boss's damage and accuracy. Avoid using prayers at all times, unless you are tanking and using the mechanic to your advantage (covered below).

Tank[edit | edit source]

For a tank role, defence is not as important as it may seem. Dual-wielded equipment is superior to two-handed because it allows use of a shield without sacrificing damage. For most demon bosses, tank gear can be replaced with power armour or void knight equipment to increase damage.

For lower levels, a beast of burden can be used to store extra food. With higher end equipment and levels (90+), a beast of burden can be replaced with a Unicorn stallion, as healing will be less demanding.

Use of prayer[edit | edit source]

Except for protect item, all prayers and curses will greatly increase a demon boss's accuracy and damage. While for the most part, prayer should be avoided, this can be turned into an advantage if executed properly.

If the boss fires an attack while Resonance is active, the effect will be disabled; however, if activated after the attack is fired, the effect can work. If the boss's attack misses, then the next attack may remove the effect of Resonance. By turning prayer on before an attack is fired and activating Resonance after, this mechanic can be used to provide very high heals (upwards of 5,000).

Demon bosses are not immune to deflect, so if prayer is active while Reflect is in effect, large amounts of damage can be deflected back on the boss. This can be combined with Resonance, allowing a high hit to not only heal you, but damage the boss as well. Do note that under Reflect, all damage received is cut in half, so Resonance cannot heal as high. You may prefer to wait until Reflect's effect is over to cast Resonance.

Transfigure can have damage absorbed to heal you. While the ability stuns and binds you, it does not prevent you from activating and deactivating prayers. Cast Transfigure at mid health (around 4,000–5,000) and turn prayer on for 1 or 2 hits (depending on how much is dealt).

Solo (Upgraded Darklight method)[edit | edit source]

This section covers methods for a player who is taking on the boss on their own.

Equipment[edit | edit source]

This specific setup revolves around hefty use of the upgraded Darklight's special, Weaken. This special attack applies a stacking Attack, Strength, and Defence debuff on the demon boss. By using this tactic, one can effectively drain a demon's accuracy and defence to such low amounts it will rarely hit the player, and will be unable to block any hits the player deals. By regularly using the special throughout the fight, the player can ensure the demon is severely weakened, making it only a matter of time before the boss falls. The state where a demon boss will miss most of its attacks is usually reached after ten successful special attacks.

Using this strategy, it is needed to effectively put as much adrenaline as possible into the special attacks until the demon is weakened enough. As using prayers (besides Protect Item) should generally be avoided, the player should be able to heal as much as possible without eating food that causes adrenaline drain. A Blood necklace (Fury or Brawler's), Vampyrism aura and Scrimshaw of vampyrism are good options for lifestealing off of the boss, while a healing familiar such as a Unicorn Stallion or a Bunyip may provide passive heals that do not cost the player any adrenaline. Saradomin brews are also a very viable option to heal up while not being interrupted. However, it is only recommended to use these if also taking Overloads, because of the 15 second re-boosting effect these potions bring.

It is possible to solo every single type of boss using the upgraded Darklight with Jessika's sword and Bandos equipment with a full inventory of sharks, with exception of the "Terrifying" suffixed bosses, unless the player is fairly experienced.

Start of the fight[edit | edit source]

Often, a demon boss will already have consumed all of its Lesser demons and Black demons generals when the player arrives. If not, it is fairly easy to kill those after finishing off all of the Imp heralds. They have high health, but do not deal significant damage or have any special properties. The player should aim to finish off the last black demon with 100% adrenaline present, so that they may immediately use two special attacks on the Demon boss.

If only the Imp heralds stand alongside the boss, it is still recommended to kill these to build up adrenaline up to 100%, in order to directly use two special attacks in succession.

Using Legacy mechanics[edit | edit source]

For demon bosses that spawn in a reasonably accessible location, one strategy is to switch to Legacy mode (to start the fight with 100% Weapon Special attack) and deposit all items except for the Darklight and an off-hand weapon. Use the Darklight's special attack on the demon twice, and let the demon kill you. As the Weapon Special attack bar resets to 100% on death, the player can immediately go back to attack the demon again without waiting for the bar to refill. Repeat this a few times. When the demon starts to frequently miss its attacks even when you are not wearing any armour, then it means you are likely ready to defeat the demon in standard combat.

Adapting to the Demon's properties[edit | edit source]

As all Demon Bosses have two traits that give them a unique effect - a prefix and a suffix - it can be crucial the player is well prepared against some of them. Every trait is explained and has a recommended strategy when struggling with the fight. This does not mean these are required by any means.

Prefixes[edit | edit source]

General[edit | edit source]

The demon boss will have more accurate melee attacks. This means it will require more stacks of Weaken in order to have the boss miss most of its attacks to you.

Executioner[edit | edit source]

The hits of the Demon Boss will be considerably higher. While this can cause some difficulty in the beginning of the fight, this trait is fairly harmless later along, as the boss will miss most attacks on the player anyway.

  • Recommended, if struggling: shield switch in combination with Resonance, Tank armour with life boost (Tetsu, Teralith).

Castellan[edit | edit source]

Previously regarded as the most difficult and/or tedious trait, this is the contrary when using the Darklight method. Because of the massive defence drain Weaken offers in combination with the high accuracy boost Darklight has versus demons, it will be easy to consistently hit the demon, especially later in the fight. This is generally considered the "easiest" prefix to fight.

Deacon[edit | edit source]

This prefix will cause the Demon Boss to have multi-hitting Magic attacks. While soloing, the player should not have any problems with this trait.

Suffixes[edit | edit source]

Blazing, Rending, Infernal[edit | edit source]

These three traits will make the Demon Boss apply a fairly weak damage over time effect on the player. Generally, these can be ignored, as the damage received is insignificant. The constant bleeding effect does open up the possibility to make very effective use of Revenge and Preparation (for Resonance), as the small damage ticks will quickly boost the abilities.

  • Recommended, if struggling: usage of a shield, in combination with Revenge and Preparation.

Corrupting, Pestilent[edit | edit source]

These two suffixes will cause the demon to apply a strong poisonous effect, either area of effect based or as a single-target bleed respectively. In contrary to the other bleeds, the poisonous one from the Pestilent bosses will actually deal significant damage in longer fights.

Frostborn, Glorious[edit | edit source]

As these Demon bosses can repeatedly stun the player, they can cut down the ability to build up adrenaline and apply Weaken stacks often enough. It is recommended to only use Weaken or other thresholds while under the buff effect of Anticipation or Freedom to ensure the player does not get stunned halfway through an attack. While Barricade also provides stun immunity if used with a shield, it is not considered worth its cost.

  • Recommended, if struggling: paying close attention to using Anticipation and Freedom as much as possible, while not overlapping the buffs.

Shattering[edit | edit source]

This trait will turn the Demon's attacks into huge area of effect damage. For soloing, this should not affect killing at all. This is generally considered the "easiest" suffix, as it does not bring any extra effect to the table while taking on the boss alone. As such, there is no special recommendation for this type.

Terrifying[edit | edit source]

Demons with this trait can bind the player and halve their adrenaline gain. While the bind may not be a problem for the player, the halved adrenaline gain can be a major nuisance, and will make the kill considerably harder. This suffix is the "hardest" to face, as it will take twice as long to gain enough adrenaline to use Weaken. Many players consider this type to not be worth the effort when using this method.

A trick that may sometimes be used while fighting the Demon boss in areas where other monsters are present, is to tag a weak monster (such as a Skeleton in the wilderness) and continue to attack the demon. While the monster attacks you in melee distance, you will often not suffer the decreased adrenaline gain.

Obscured[edit | edit source]

As this Demon boss will drain your stats over time, it can be wise to counter this effect by bringing stat-restoring or even stat-boosting measures. When using Overloads, the stat-draining effect is negligible, and can be ignored.
