Note:
As of patch 2.4.3, libram switching is no longer possible. You'll want to disable or delete this mod immediately.

Holy Librams! is a tiny addon with a narrow purpose: to automate libram-switching in order to maximize either the healing throughput or mana efficiency of holy paladins. It includes logic to manage alternating between the Libram of Mending and the Libram of Absolute Truth and works in a 100% transparent manner in and out of combat.
