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[]

  • Guarded by warlocks, up to a max of 4
