I did the attached quest of killing 20 wasps and workers and getting their green crunchie bits.  So I quietly slayed them one at a time, getting 474-550 xp per kill until I had picked up the 20 drops.  Then went behind the two nests (south) and sat on a little hillock until flapping stinglasher came by.. despatched him effortlessly and all told with quest Xp... kill xp got 23,000 xp and a deceny drop of armour sold at 2G. I was a 46Lvl Paladin... whole lot 35 mins a nice leisurely quest.
