D2 Affix

Monsters can spawn as elites with random affixes (Cold Enchanted, Extra Fast, Teleportation, etc.) and auras (Might, Holy Freeze, Conviction, etc.), classified into five tiers: Common / Champion / Unique / Super Unique / Minion, distributed by difficulty-based weights. Killing the Ender Dragon unlocks Nightmare difficulty; killing the Wither unlocks Hell difficulty — higher difficulty spawns stronger and rarer elites. Supports entity tag restrictions (undead, beast, etc.), configurable whitelist/blacklist and equipment pools. Adds crossbow AI (non-Common elites auto-switch to firework rockets), bow AI, and trident AI to vanilla mobs. Includes 13 custom attributes (resistances, critical strike, thorns, render channels), 8 custom damage types, and 3 immunity potions.
