The Bile Demon is a fat creature in Dungeon Keeper and Dungeon Keeper 2.

Dungeon Keeper[]

"A very big, red, greedy creature that eats you out of house and Dungeon if you are not careful. Despite this, they are excellent fighters and as hard as nails. Also, their primary job is manufacturing. If they don’t get enough food, they will get angry and sleep until food arrives."
— Dungeon Keeper Manual

Bile Demons are powerful combatants, with ample health, access to area-of-effect gas spells (to which they are immune), and morning stars chained to their horns, which deal decent damage. They work especially well in groups, since these poison gas clouds stack and can wipe out whole teams of foes that close in. Bile Demons should not be paired with any melee-bound allies that can be harmed by poison gas.

At level 4 they learn Fart, a unique area-of-effect spell that works like Poison Cloud at melee range and does not hurt allies, but they will continue to use their Poison Cloud as well in their attack rotation. Bile Demons' massive weight means that they are not affected by Wind, so they are especially good to throw in against an enemy Priestess.

The challenge of retaining Bile Demons is not their salary, a modest 406 gold at level 10, but their Lair space requirements, the fairly-high cost of training them, and their excessive use of the Hatchery. Bile Demons crave 6 Chickens every 4500 Turns. Build the Hatchery adjacent to their worksites and make it very efficient, or they will waste a lot of time waddling through the corridors and possibly get angry. Fortunately, they handle their restroom breaks in combat.

Bile Demons are proficient craftsmen (in fact, they're joint second best with Orcs and Mountain Dwarves, according to their raw manufacturing skill ratings), and their default job is manufacturing in the Workshop. They can be dropped into the Library, but perform research only with very basic ability. They will not take damage when slapped, although it still lowers their happiness.

Trivia[]

  • This creature's abysmal base Dexterity of 40 likely emerged from confusion during development, because it was supposed to represent the melee evasion rate— with Bile Demons making very wide targets. As a result of this score, however, Bile Demons will seldom land hits in melee. Most of their damage will come from their poison gas attacks. They are not very effective against gas-immune creatures.
  • Bile Demons are natural enemies of Skeletons, and the two species fight if placed in the same Lair; they also refuse to group with each other in a Barracks.

  • Whenever you slap a Bile Demon, they will briefly display two fingers up at you in anger.
    • In Australia and the UK, this two-finger salute, always done with the back of the hand towards the target, is the equivalent to flipping the middle finger in the US.
  • In at least one Dungeon Keeper prototype, Bile Demons were not immune to Wind.
  • In at least one early version of Dungeon Keeper's intro, the Bile Demon's growl at the Knight is heard.
  • 'Perfidious Yuck' was an early name for the Bile Demon.


Dungeon Keeper Unused Frontend
  • In the data of the first game, there is an unused screen of Dungeon Keeper text with a Bile Demon standing behind it. It is likely that this is an early loading or title screen, or possibly a main menu backdrop.


  • Before the revamp in 1996, Bile Demons were well-armoured and powerful spellcasters.[2]


Dungeon Keeper 2[]

Bile Demons are huge and gluttonous creatures cursed with notoriously poor control of the most rudimentary bodily functions. Their primary use is combat, a field in which their success owes more to their hefty bulk than to any particular combat skills, despite the flail-like horns. However, they do also have basic construction skills, so can be put to work in the Workshop.

Dungeon Keeper 2 Bile Demon concept art

DK2 Concept Art (Dungeon Keeper 2 Manual)

Bile Demons, not best known for their intellect, loathe researching. They also have an ongoing antipathy towards Giants. If possible, they’ll set up their beds in the proximity of a Hatchery to avoid having to waddle too far for food.

The Bile Demon is the slowest creature you have, but is also the highest health creature you can attract. They need food, a lot, so place plenty of Hatcheries around to avoid unhappiness.

They have extremely high health, 1/3 more than a Black Knight, and even more than a Royal Guard, and tend to outlast most creatures in a combat pit melee, even if they are 3 or more levels lower.

Progression

Overview[]

Bile Demons were huge gluttonous creatures that spewed forth a poisonous stream of gas. Hygiene wasn't one of their strong points and had developed an immunity to poison.

They were attracted to wealth and could not get enough of it! They would make their way to the nearest Treasury or Warehouse (whichever was closet) when placed in an enemy dungeon.

Apart from their love of gold and stone, they also loved to eat and, as such, liked to reside in the Hatchery, gorging themselves on chickens.

In order to get a Bile Demon for your dungeon, you required a Hatchery.

Notes[]

  • Very effective against Treasuries and Warehouses.
  • Portrayed as a 'tank' with heaps of health, though isn't as tough as you'd think.
  • After all resource rooms were destroyed, they would attack the nearest building.
  • Not very effective against doors, which were often blocking their way to resource rooms.
  • Took extra damage from Skeletons, though this could be reduced to 1.5x.
  • While Skeletons were immune to poison damage, Bile Demons could still damage Skeletons quite effectively.
  • Very effective against Warlocks.
  • High level Bile Demons were good for holding Trolls from attacking Hatcheries.
  • Very weak against Vampires.
