Equip: Your attacks have a chance to summon a member of your Army of the Dead.
APOCALYPSE! 2 sec Cast, 45 sec cooldown. Channel the power of Pestilence, dealing (880% of weapon damage) damage and applying three stacks of Festering Wounds.
On another note, the fluff text and trait names make it seem like the acquisition quest will have us up against the Four Horsemen of the Apocalypse.
Frost weapons have a chance to invoke the spirit of the past Lich King, deal dmg and grant us effect.
