The Library

The Library is an Act 2 event where the player enters a grand library filled with books. They can sleep (heal 15 HP and forgo any card reward) or browse the shelves (choose one card from a selection of 7 cards from any character's card pool to add to their deck). Sleeping provides healing while browsing provides a card.

The Library presents a consistent choice between HP recovery and card acquisition. If at low HP and lacking healing resources, the sleep option can be life-saving. If at high HP, browsing for cards from a pool of 7 (which may include powerful options from other characters) is typically more valuable. The cross-character card pool makes The Library uniquely capable of providing rare cross-class synergies unavailable through normal card acquisition.
