You all triumphantly return topside. There's a dockside bar, or you can return to the Guild or go shopping.
Before heading up, Mustave heals himself the rest of the way with his Healing Belt.
Once he gets up there, he looks to see if he can purchase 40 flasks of acid. If he can find a place that deals in magic swag, he looks for a
+2 Vest of Resistance and/or a
+2 Cloak of Charisma. If so, he'll see if they'll accept his
Cloak of Resistance +1 and/or his 8 scrolls of
Grease for part of the trade.
When his shopping is done, Mustave heads back to the guild. He checks in to report how things went, deposits the 5,000 gp reserved from the 50k found, and asks if there is any news.
OOC: when do we return for the guns?
