Basic Weakauras for every bossfight and trash mob in Karazhan.
Contains most of the important boss and trash debuffs, buffs and casts. Some weakauras require the nameplate of the mob to be visible.
Most of the weakauras are based on Spell IDs and/or NPC IDs, but some may only work with the english wow client
