About

Cinema-grade boss content. Six themed dungeons spawn naturally across the world. Each houses a multi-phase boss with custom AI, attack patterns, and tier-defining drops. Bosses scale roughly: Harbinger (early), Leviathan (mid, deep ocean), Netherite Monstrosity (late Nether), Ignis (Nether forge), Ender Guardian (mini-end-dungeon), Ancient Remnant. Drops are used by Cataclysm Weaponery-tier weapon recipes.
