Super Unique monsters are unique monsters, usually tied to quests, and spawn in the exact same place every single game. They differ from random uniques, which are randomly generated by the game engine and do not appear in all games. They include the Three Prime Evils, the lesser evils, and their lieutenants and underlings. They have special abilities, attacks, appearances, and are without a doubt the toughest monsters you will find in the game.
