Putrify

Putrify is a Monster Skill used by Putrid Defilers in Act V of Diablo II: Lord of Destruction. Though it seems harmless, it can prove deadly when left unchecked.

When a Putrid Defiler casts Putrify, the Defiler will hover towards another nearby monster. The monster will receive a special aura, appearing as reddish-yellow lines. When the monster is killed, several Pain Worms spawn from its corpse. When multiple monsters are infected with Putrify this can prove challenging.
