Last night, I picked up my the shadow specialty. I went to the Altar, did the quest, etc. Got back to Shat and noticed that it gave 9500 experience. So...I got to thinking "Hey, with that bonus...maybe I could just drop and repeat over and over again!"
Is this possible to do? I would test it, but I'm not crazy about finding out that I can't do the quest again. Also, doesn't it cost money to drop it?
