I just got a level 14 after returning the crown. No specials, but I got lucky getting a wand of mapping early. I used my single scroll of teleport in the hall of the king and landed near the treasure room in the top left and got a recurve bow of poison. That and fire arrows smoked the king. The only way it could have been better was with a potion of clairvoyance or two, because I didn't get any moonstone or mining helmet. Anyone have any tips?
