Pandemonium Event
Andariel
- "Die, maggot!"
Andariel, Maiden of Anguish and lesser evil, is lurking within the depths of the Act 1 Catacombs. She is the leader of the corrupted rogues. She has mastered the vile arts of poisoning, and heroes challenging her should keep in mind that she is particularly vulnerable to fire.
Duriel
- "Looking for Baal?"
Left behind by Mephisto as a surprise for unwary adventurers, Duriel, Lord of Pain and lesser evil, is guarding the ancient tombs of Tal-Rasha. Charging with demonic speed, he is a formidable foe especially to heroes lacking vitality and defenses. To make matters worse, he also employs a freezing aura to chill mercenaries unfortunate enough to face him to the bone. Duriel is often fought up close or against a wall, so he can't make repeated charges.
Mephisto
- "My brothers have escaped you."
Mephisto, Lord of Hatred and a greater evil, lurks in the depths of his Durance of Hate of Act 3, well guarded by corrupted council members, undead stygian dolls, and more hellspawn. Even the spirits are allied with him in his lair, although you will have worse things on your mind if he fires a skull missile at you.
Diablo
- "Not even death can save you from me."
Diablo, Lord of Terror and a greater evil, feels right at home in Hell, where he unleashes flames and lightning to fry unprepared victims where they stand. His thick carapace makes him hard to score physical hits on, unless they are magical projectiles or spells.
Baal
- "My brothers will not have died in vain!"
Baal, Lord of Destruction and a greater evil, hides in Mount Arreat, where he plots against humanity by using the Worldstone to finally literally raise Hell on Earth. If challenged, he is happy to demonstrate his powers in sorcery by summoning monsters, creating clones of himself, and draning mana of his victims.
The Cow King
- "Moo-moo moo moo moo, moo moo-moo moo?"
The infernal Cow King is not your regular cow, and with his legion of halberd-wielding cows is eager to make short work of any who dare to enter his realms. The Cow King can occasionally drop special set item pieces, forming the rare Cow King's Hide set.
