Demons
Activated Vessel

The Activated Vessels are the creatures into what Dark Vessels transform into, if they successfully summon a demon into their own bodies. They are one of the more disturbing monsters seen in Diablo III.
Activated Vessels are mutated, half-demonic beings who fight furiously and move very quickly. It is a good idea to kill off the Dark Vessels before they can activate, if at all possible.
Activated vessels have impressive death animations, standing still, shaking, and then shooting out embers of red light, like parts of the demon dispelling into the air.
Dark Berserker
Berserkers are Animals. It is likely that this monster is called a Berserker, and Dark is a subtype applied to Berserkers and a variety of other related evil human monsters.
Berserkers are the muscle of their evil, demon-worshiping cult. They are massive, powerful men who wear hoods and loincloths and carry huge mauls, with which they are happy to bash your brains in. Berserkers have a special overhead smashing attack, which they telegraph by powering up their mauls with a reddish glow. Their overhead attack is highly damaging, but if you dodge it the Berserker will hit the ground so hard their maul breaks through the ground and gets stuck there. While the Berserker struggles to pull his weapon free, he is defenseless and can be killed swiftly.
Cultists are human mages who spawn with Berserkers. Cultists are very weak, but they can shoot fireball projectiles and summon powerful Dark Demons, so it’s wise to bypass the hulking Berserkers to kill the Cultists as quickly as possible.
Cultists can be recognized from Dark Vessels by their lack of a staff. Vessels have a long staff which curls at the end, on which they lean while summoning up the demons by which they are possessed.
Dark Demon
Dark Demons are demons. These odd, half-skeletal creatures are summoned from raw, red manhole-like openings in the ground by Dark Cultists.
They are quadrupedal, and look a bit like a dog crossed with a crocodile, then turned inside out. They are quick of foot, but appear to possess only melee attacks.
