Originally appear as corpses but act in the same way as the Protean Spawns, coming back to life at around 40% health and attacking. After being aggro'ed until some time after their death they regularly hit random nearby people with "Energy Discharge" for 700-1000 Arcane damage. They are immune to taunt, and many other aggro-generating or reducing abilities. They also reset aggro from time to time, which makes them very uncontrollable. When they get low on life (about 5%) their hands begin to turn blue and they stop doing anything, including moving. After some time they will explode for about 4k-5k damage. Watch out for their arcane discharges which even continues some time after their second death.
