The Library is a room in Dungeon Keeper, Dungeon Keeper 2, Dungeon Keeper Online, and Dungeon Keeper Mobile that enables researchers to unlock new rooms and Keeper spells for their master. It can also serve as a storage area for captured Dungeon Special boxes.

Dungeon Keeper[]

The Library is one of the "basic five" rooms that are nearly always available for construction. Creatures skilled in research can work in the Library to develop the more advanced spells and rooms available in the scenario. The Library attracts Warlocks through the Portal whenever they are in the Creature Pool.

Research Path[]

Dungeon assets can be unlocked in a pre-designated order shown left-to-right, top-to-bottom in the table below. Most campaign and skirmish levels start the players with the first nine of these topics, down to and including the Training Room, already researched. Campaign levels also have some items disabled entirely.

Researchers[]

Some creatures are natural researchers with intellects and otherworldly knowledge, and some are not. Research is particularly serious business for Wizards and Warlocks. They have a "Job Stress" attribute uniquely associated with Library work, and will attack "unworthy researchers" (any creature for whom Library work is not a primary or secondary job) that is attempting to work in or pass through the Library. They do this regardless of the creature's Research Skill, which can be ironic because they'll happily work with Ghosts, but will kick Avatars out despite them being superior researchers (see below).

This behaviour requires a ranged spell[Note 1], which Warlocks gain at level 2 and Wizards already possess at level 1. Level 1 Warlocks can work alongside "unworthy researchers" without difficulty.

Research & Spellbook Mechanics[]

A spellbook

Ongoing research activity produces gay firework-like magical sparks, and when something has been researched, the room's occupants will cheer to the accompaniment of a more spectacular display.

A spell that has been researched appears in the form of a glittering spellbook. These books are capturable objects and use up space in the Library. Some map scenarios harbour spellbooks in dangerous areas that can be captured and carted to the Library by Imps. Enemy Wizards on the Hero side sometimes prioritize entering the Keeper's Library and "stealing" (destroying) the spellbooks. If the Library itself is sold or destroyed, its spellbooks will disappear, and you will have to research the spells again (in KeeperFX, if you have another Library, spell books will be transferred there instead if it has remaining capacity).

A Room that has been researched does not generate a corresponding capturable object. Room advancements are retained by the Keeper permanently once achieved, no matter what happens to the Library.

You can see the progress of the current research project by clicking on the “?” Icon (the Information Panel) on the far left of the Control Panel.

Recommendations[]

The Library needs to be isolated from thru-traffic while still in reasonable proximity to a Hatchery and Treasure Room. To research spells faster, build more Library space and throw more creatures into it. Since completed spells also use Library space, bear that eventuality in mind when deciding on dimensions for the room. Finish fortifying the Library's walls before introducing a trained Warlock or a Wizard to the room, or you risk losing Imps.

Warlocks and Dragons will often enter the dungeon and begin researching as soon as the basic rooms are up. Acquiring different sorts of creatures with skill in this task usually requires a great deal of effort and pre-existing research. Dullards can help research in a pinch as long as the Warlocks working in the room are untrained, but their contributions will not be impressive.

For much of the original campaign, a level 10 Vampire can be transferred. On some levels it is possible to transfer a trained-up level 10 Wizard— with his combination of high research value and killing power, he can be as formidable overall as the Vampire, and he works for one-sixth the payday (apparently the joy of blazing through your research topics and perforating enemies pays for itself).

The Library is your dungeon’s research centre, where new spells can be discovered and known ones upgraded. It is a furnished room, and can accommodate one researcher per bookcase or shelf/podium, plus one. A functioning Library attracts Warlocks. Other evil creatures who will research are the Vampire, Dark Angel and Maiden; on the heroes’ side, the Fairy, Monk and Wizard are also keen scholars. Wizards were the very best research aces until Almaric (the Elite Warlock), Kessler Van Doom (the Elite Vampire) and Zachariah (the Elite Dark Angel) came along.

All other creatures (including the Elite Skeleton, strangely) have 0 research skill.

In the campaign, on levels where a new spell becomes available, it must first be researched. Once this is done, a spell book will appear above the central bookshelves in your Library. These spells will subsequently be available at the start of each new level. At the beginning of a new level, all your known spells start at grade 1 and can be researched to grade 2 (upgraded).

In Skirmish and Multiplayer modes, the Library is used to upgrade known spells. It is possible to research a spell by claiming a Library that contains the spell book for it. Researched spells can be lost if the Library or bookcase where it is stored is claimed, destroyed or sold.

The Library is also used to store magic items. Once your Imps claim a land tile that contains a magic item, they carry it back to the nearest Library, where it is stored above the central bookshelves and can be accessed via the Spell Casting tab. Each of your Library’s central bookshelves can store two new spells or magic items.

  • If you have multiple Libraries, spells appear in the one where research towards the spell was last conducted.
  • Magic items in the Library can't be picked up, but if their Library loses tiles, they may be moved.

All spells require 500 Research Points to research, and their upgrades require an additional 1500.[3]

Dungeon Keeper Mobile[]

Dark Library

Dark Library

Overview[]

Cell service down below is non-existent, no matter WHICH carrier you use. And I'm afraid there's no Wifi, Keepers. So if you need to do any kind of research (particularly the arcane kind), you're going to need to visit a Dark Library!

Available early on in the game, several astute Keepers might argue that the Dark Library is one of the most important structures you can build in your Dungeon. Used to generate and store Mana (the magical energy used to fuel your Spells), the Dark Library is also where individual Spells are researched prior to becoming part of your arsenal.

Comprising a 4x4 area in your Dungeon, upgrading the Dark Library will grant access to more potent Spells, in addition to bolstering the defensive strength of the Library's inherent defenses (bolts of electricity, which are able to target both ground and air targets). Upgrading also increases the maximum amount of Mana at your disposal.

So don't forget your library cards, Keepers; you're going to want to make regular visits! Just don't expect this library to be very quiet, like most regular ones. In fact, you're bound to hear more than a few screams... but it's really not all that different from elevator music, now that I think about it. Delightful!

Notes[]

  • Unlocks access to Spells
  • Generates Mana to cast Spells
  • Unlocks the Warlock
  • Does not regenerate mana whilst it is being upgraded
  • Bolstering reduces spell costs and increases the rooms health
  • Does lightning damage which is effective against Tiny and Ghosts
  • Guarded by warlocks, up to a max of 4
