Description: Defeating Croesus
Please add tips to the subpage, rather than the article below.

Croesus is a giant fungal boss, part of the Croesus Front in the Elder God Wars Dungeon. It was revived by Bik in the Senntisten graveyard in order to attack the forces defending the cathedral from the Elder Gods.[1][2]

Croesus is the game's first skilling boss. Having at least level 80 Construction, Fishing, Hunter, Mining, and Woodcutting is recommended when engaging the boss, although these are not required. Instead of relying on Constitution to survive, the player has a "health" bar, dependent on their skill levels, as their primary health. If this bar empties, the player will fall unconscious and be returned to the arena's entrance. Any player removed from the encounter this way will not be able to rejoin it until Croesus returns to its dormant state.

Despite being a skilling boss, Croesus does have all the features of a regular boss. In order to be assigned Croesus for Soul Reaper, the player must enable receiving skilling boss assignments in the Soul Reaper settings. Unlike the other bosses in the Elder God Wars Dungeon, Croesus does not have a hard mode variant.[1][2]

Drops from the boss include the Scripture of Bik and incomplete variants of cryptbloom armour, a powerful set of tier 90 magic tank armour, as well as skilling off-hands for both Mining and Woodcutting.

Obtaining all of the unique drops from this boss completes the achievement Some Fungi are Only Edible Once, unlocking the title [Name] the Infected.

Location[edit | edit source]

Croesus can be found at the Croesus Front on the eastern side of Senntisten as part of the Elder God Wars Dungeon.

If you're looking for teams/public instances. Players have been using World 68 which is the group bossing world.

Mechanics and strategy[edit | edit source]

Croesus cannot be killed, and needs to be put to a dormant state. To do that, the players need to clear fungus from the trophy carcasses of four beasts, found near the graves of four heroes from the Second Age. Clearing out the graves reduces Croesus' strength. However, the fungus can grow back, which can be slowed by using the collected rotten fungus. After collecting enough materials, the players can use Construction to restore four statues of the heroes, and pray to them to temporarily subdue the boss. This grants access to Croesus' fungal core for a period of time. Once this core is destroyed, the encounter ends.[1][2][3][4]

Croesus does not directly damage players, instead they possess a blue health bar, signifying their skill levels. If this bar empties, the player is removed from the encounter. This health can be restored with potions and other stat-boosting items, and the drain can be reduced by wearing the shadow pontifex ring upgraded with resonant anima of Bik. Higher levels in respective skills, better tools, and elite skilling outfits are all beneficial during the fight. The player's contributions in subduing Croesus determine the amount of experience and rewards obtained - masses provide faster kills, while smaller groups provide better experience and rewards.[1][2][3][4]

History[edit | edit source]

During the Second Age, shortly after the end of the Kharidian Campaign, a Praetorian expedition that had been sent to the Unquiet Ocean returned to Senntisten with a very unusual species of fungus. They intended to use it as a biological weapon against the Zarosian Empire's enemies and as political leverage.[5]

In their laboratories, they were able to turn the fungus into a being which they called Croesus and experimented on it, feeding it slaves, burning away weaknesses and continually evolving it. This was done so well that Croesus was eventually able to break out of containment and into the city; while the breach was considered serious, what happened was unknown. They were then ordered to stop experimenting on it.[6]

This order was ignored - Croesus, now even stronger than before, broke out of containment again and was able to infect one of the city's districts, feeding on the citizens to empower itself. The Tenth Legion was recalled from the Empire's borders to combat the fungus. Gorvek, along with the legion, razed miles of city in an attempt to contain it, but they were unsuccessful. The legion was almost wiped out, forcing Zaros to personally intervene. He quarantined the district by burying it beneath the earth. [7] Zaros' intervention prevented it from spreading further, but it had already killed 50,000 people by the time it was stopped, creating such an impact that Zarosians called its rampage the "year of Croesus".[8] Without new hosts to infect and sustain itself, Croesus either died or fell into a dormant state.[9]

Croesus' rampage would soon be a distant memory by future Zarosians, who thought of it as legend or nonsense. Only Yokai, a Zarosian witch, appeared to be aware of the existence of Croesus and was prompted to dig at the graveyard to unearth it for reasons unknown.[10]

In the Sixth Age, 7,000 years later, Bik found Croesus beneath the graveyard of Senntisten and revived it, commanding it to reclaim the Elder God eggs. It massacred the troops of the Varrock and Lumbridge Guard that were stationed at the graveyard by Seren.[11] Fortunately, the World Guardian and their allies were able to turn Croesus' fungi against it, preventing it from growing too strong. Despite their efforts, Croesus continued to advance towards the cathedral.

The following takes place during Extinction.

Croesus continued moving towards the cathedral, somehow eventually moving from its spot at the heroes' graveyard to the normal one. The World Guardian was able to destroy the mutated nodes powering Croesus, putting it in a dormant state and relieving pressure on its front. While the World Guardian was tracking Seren and the eggs, Armadyl incinerated Croesus, eliminating all traces of the mutated fungi to prevent it from returning for good.[12]

Drops[edit | edit source]

Rewards for subduing Croesus are determined based on the player's participation in the encounter, called the contribution factor, which includes the following:

  • Gathering fungi from the trophy carcasses
  • Placing fungi at the statues of the four heroes
  • Restoring the statues
  • Removing energy fungi
  • Freeing other players from sticky fungi
  • Damaging the core of Croesus, and interacting with green (blue in colourblind mode) and white spores on the core

Actions that will decrease the player's contribution, and should be avoided, include:

  • Gathering from rotten nodes
  • Healing Croesus by interacting with red spores on the core[13]

At the end of a successful encounter, the player's contribution factor is displayed in the chatbox. This determines the number of times the reward table is rolled at the end of the kill. Starting from a factor of 60, players additionally have a chance to access the unique drop table, which contains 9 items: the 5 incomplete parts of the cryptbloom armour set, the Croesus foultorch, Croesus sporehammer, Croesus spore sack, and the Scripture of Bik.[14] The player can roll at most 10 common drops; the 11th and 12th rolls on the reward table can only give unique rewards, or nothing.[15]

Contribution factor Rolls Chance of obtaining
at least 1 unique
Chance of obtaining
at least 1 of a specific unique
0–19 0 N/A N/A
20–59 1 N/A N/A
60–99 1 1/600 1/5400
100–179 2 1/300.3 1/2700.3
180–229 3 1/200.3 1/1800.3
230–279 4 1/150.4 1/1350.4
280-309 5 1/120.4 1/1080.4
310-329 6 1/100.4 1/900.4
330–344 7 1/86.1 1/771.9
345–359 8 1/75.4 1/675.4
360–379 9 1/67.1 1/600.4
380–399 10 1/60.5 1/540.5
400–419 11 1/55 1/491.4
420 or more 12 1/50.5 1/450.5

Using the above table, we can calculate the odds of getting a unique drop in an hour. With an experienced four-man team, 9 kills an hour can be assumed, and a contribution score of at least 420 every kill. This results in a 17.82% chance to receive any unique drop in an hour. In contrast, in a public instance, the number of kills an hour can be nearly doubled at a cost of reducing average contribution scores to a 180-229 range. Assuming 16 kills an hour, this leads to a maximum of 7.69% chance of getting a unique drop in an hour. This means that four-man teams are ideal for profit per hour with a higher unique reward chance and more plentiful other loot.

Higher contribution also increases the amount of Croesus flakes awarded to the player. It is possible, although unlikely, to obtain multiple unique items from a successful encounter, as both a group and individual.

Rewards are placed in the chest near Gorvek. They can be accumulated from multiple kills, as long as the player does not exit to lobby or log out of the game. If they do so, the rewards will be sent to the bank - if the bank is full, items are sent to the player's inventory. If the inventory is also full, then the items are lost. If the chest becomes full, additional loot will be placed on the ground in front of it.

Trivia[edit | edit source]

  • Croesus is named after the ancient king of Lydia known for his magnificent wealth and hubris, fitting for the boss' name as it was a source of Praetorian greed and pride.[16]
  • Croesus was first hinted by the blood warden who mysteriously stated "The roots claim the dead.", referring to its preference to feed on dead organic matter. It was later hinted again by Yokai, who sought out a "monstrous fungus" at the graveyard. The boss was later hinted again during a teaser in which it showed a fog of sorts with roots moving in the background.
  • Similarly to the Arch-Glacor, Croesus in the overworld appears as an environment piece rather than an actual NPC. The dead harvestable guards that are found near the large carcasses are not seen in the overworld either, only appearing in an instance.
  • Of all the "generals" in the God Wars Dungeon series, Croesus is the only one to be killed in a lore perspective.
  • Croesus is the only boss of the Elder God Wars Dungeon who doesn't have any drops related to tier 95 equipment.
  • The sound effects of Croesus were made by Mod Surma by cracking vegetables (for the bone movements), as well as recording pig noises and squeaks of a swing (for the shrieks and screams).[17]
  • Croesus' character model consists of 187 bones, 13 away from the limit of 200 for characters. The limit is there to not cripple the game's framerate.[18]
