Barrigan Turaen is a panhandler located near the House K. gate in the Marketplace. Right now he makes a few random statements about the condition of the Marketplace. Why don't you make him useful? How about he actually begs for coins. Maybe he's a djin in disguise. Give him some coins and he casts an unknown random spell on you as in the Potion of Wonder. They don't necessarily have to last like the spells we get from the House P. and House J. vendors (although that would be nice). But, if there is a panhandler, let him beg for coins.
