A question to the group, and I apologize if someone has asked this previously.
I am running a convention one-shot session. The adventure is written without time for the party to take a rest and level up. The adventure takes place in the course of a few hours.
Part of the consolation prize for rolling 6- is marking XP, and I love that. For this game though, it does not seem like there is a way for players to utilize their XP.
Has anyone done on-the-fly leveling of characters or any other use for accumulated XP during the course of the adventure?
