During a long campaign you can divide XP's at resting points. If you recall I did give out XP's just before the group entered the lair since a few members did face some encounters. Rasarow I believe had enough to go up to second level.
As for the sealed chest I will send Randall the contents so our Psion can open it at a rest point. If you shake it hard enough you may hear a +10 Orc Battle Axe, A sure shot barbarian bow, and an orc spear of returning inside the small handheld chest(jk)
I can meet on Mon-Thurs from 8:30pm to midnight EST.
