Quest:In Service of the Unholy

Objectives
Koltira Deathweaver at Agmar's Hammer in the Dragonblight wants you to use the Unholy Gem on Duke Vallenhal and return to him with a Filled Unholy Gem.

Provided Item: Unholy Gem

Description
The power of the unholy is coveted among my kind. It makes up the very fiber of our existence, granting death to those that dare make a mockery of it! Thankfully there is a fount from where I may draw from in my time of need.

Take this unholy gem and make your way to the Ruby Dragonshrine, east of here. It is there that you will find Duke Vallenhal, death knight of Arthas. Weaken his resolve in battle and unleash the power of the gem upon him. It will finish him off and steal his unholy energy!

Progress
Fill the gem with the power of the unholy!

Completion


Impressive. You bested a death knight of Arthas... Clearly you were not alone... but still...
