It's a Cruma Tower quest. Not sure why you'd need it anyway, if you farm Cruma Tower from 40 - 50 you can pound those 10 levels in about 2 hours if you solo it. Even after the mobs turn green and light blue they still give out about 12-18k exp if you have vitality. Then again if you do it you only have to kill about 20 mobs in CT before its done so its only adding to my point anyway. Which is goto CT for 40-50
