Hey Tuna. Check out this quest. There is a group of 3 ogre mercenaries bundled up at the prison area in East Wastes (#2 on the map), which drop the quest items. Drop rate for this quest is about 70% or more. Just bring a lot of empty bag space. Ogres are about level 38-40. Gives Yelinak faction too! Got my mage some good exp through the low 50s which was nice. Good luck!
