For me would have to be running Catacombs on Singh and getting in a argument with somebody in general chat that was Margruite Dryden able to be brought down or not. After about 10 minutes on my paladin, I did manage to kill her, much to the other persons surprise.
Still have to kill whisperdoom in Tanglegroot tho.
So Sarlona, share some good and funny memories. Regale with the tales of your adventures. Heck just tell me of a good prank you pulled on pugs.
