Koltira Deathweaver on Orgrim's Hammer wants you to use the Abomination Reanimation Kit to create a Reanimated Abomination, which you are to use to kill 15 Icy Ghouls, 15 Vicious Geists, and 15 Risen Alliance Soldiers.
15x Icy Ghouls Exploded
15x Vicious Geists Exploded
15x Risen Alliance Soldiers Exploded
They can be a very capable enemy. I've seen them turn the tide of battle more than once. What few realize, is that they can also be very capable friends.
They are not deep thinkers. If you know the secrets of their creation, you can issue them basic orders that they will not question.
Fortunately for you, I know these secrets.
This kit will reanimate the remains of the abominations you defeat. Take it, and learn to use them against the Scourge on the death gate.
