[Glitch]

I'd say exping off of an overlooked broken quest is pretty creative rather than exploitative. It's not like the mob is particularly easy (it's actually pretty hard for its level, being rogue class and all), and it's not like it somehow prevents you from needing to med between kills. The only advantage to it is the instant respawn trigger (also limited by recovery time) and the misty thicket zone exp.

Oh, and the turn-in exp from the leg

and

and

holy fuck nerf this immediately.
