Although weak, they are capable of rather powerful backstabs (400+ dmg). Also, they probably have the largest aggro radius when compared to any other mob in PoF. These are the guys that can make breakins difficult.
These mobs are the most annoying mobs in poh... Thanks to their random teleportation that throws you around like mad. On a good note, their relatively weak and can be taken down with ease. The only loot I've seen them drop is the eyerazzia(sp?).
