Disco-Tamer with a high end GD. 1150 luck suit without a statue buff.
IMO room selection is key to being successful in Covetous. As a tamer I try to avoid the mobs with AOE... things like wither really screw up my vet. You also have to be careful of the nearby rooms for those mobs that open doors. I like going through the first locked door on the east and camping the room at the end of the hall.
