Boasting extremely high Dexterity, Thieves are your go-to trap busters. This may not seem all that important, until you realize that all the gold you get in the game is found only in chests that monsters drop, and there is about a 99% chance those chests are booby-trapped. Trust me, you want one on your roster somewhere, lest your whole party suffer poison, viruses, or just flat-out damage.
