Rise of the Demon Lords
He's the BEST! At what? Ask him!
Jimjar has a devil-may-care attitude, a fondness for coin, and an obsession with betting on virtually anything and everything. He regularly offers the other prisoners bets on things! He sometimes uses betting to goad others into doing things.
So far, he’s always been true to his word, managing to keep exact track of his debts in his head. He does his best to get along with everyone.
His behavior is unusual for the usually dour deep gnomes, and others of his kind (and everyone else, for that matter) find Jimjar annoying at best and unstable and potentially mad at worst.
