He is much larger (and tougher) than any average Goblin, but is just as harmless. While he cannot attack directly, and moves slower than normal Goblins, he has a Jailer affix and will summon other demons (mostly Phasebeasts) at his side. In return, he will not escape through the portal, instead retreating and summoning more and more minions until he is slain. After patch 2.0, he uses the model of Gem Hoarder.
