How in the hell are you supposed to complete the Level 40 WHM quest O Brother Where Art Thou? The 4 sprites kick my ass before I can even kill one. I use Stoneskin, Protect and Regen before the fight starts. Next, I Repose 3 of them. Trying to keep the other 3 asleep while attacking one runs me out of mana way too quick. There has to be some better way, I can't imagine that a Level 40 WHM wouldn't be able to finish a Level 40 quest.

What am I doing wrong?
