Though d1 doesn't have AI curses, but its expansion Diablo: Hellfire has berserk :
https://diablo2.diablowiki.net/D1_Spellbooks#BerserkBerserk is a curse-like spell that resets a monster's AI, and makes them hostile to their own kind. Monsters will fight other monsters when Berserked, but they are not necessarily on the character's side; they simply attack whatever is nearest. This spell is best used as a decoy or diversion; turning an army of monsters with Berserk can be amusing, but it's not an especially viable strategy.
Berserked monsters deal enhanced damage, (20-30% + Slvl). Players do not receive experience for monsters killed by a Berserker. Berserkers are not immune to player damage, and can be killed just like any other monster.
Though Berserk does not deal direct damage, it is considered a form of magic, and thus will not work on magic immune monsters. All unique and special monsters are also immune, as are monsters in mid-charge or who are phasing in or out. There is a 50% chance that magic resistant monsters will not be Berserked.
