The quest itself is pretty simple, and goes in two parts.
- Hunt down Wretched Devourers and Wretched Fiends, and slaughter them for their Mana Remnants. You'll need four Remanants, and the drop rate felt like it was around 50%. The mobs are only level 68, and don't pose much of a problem; they do a puny drain life/mana and a very short silence. They can be found starting in the Shattered Sun Staging Area and spreading in an arc down near the western shoreline.
- Once you have your four Mana Remnants, come back up near the Staging Area to a Crystal Ward (pictured, at 49,35) and right-click the stack of Mana Remnants in your inventory. There's some nice pretty zapping effects, and you're done with your quest. 9g and 150 Shattered Sun rep await you.
