Daggerface is a (possibly insane) Dwarven dragon shaman (1st level, possibly with other levels in fighter or something). He was originally a mine supervisor named Huevo in Corso's Chasm, but became an adventurer after being horifically scarred both physically (with a knife) and mentally (by being left in a magic fear cave) during the Drow incident in epiosde one. He joined the party in episode five.
Interestingly, Daggerface appears to be immune to the effects of the Astral Plague. The mechanism of this resistance is unknown.
