The Copper Monstrosity Revived

The Copper Monstrosity Revived is a boss-rematch side quest in the Rainy Plains, and its two objectives say everything: enter the arena, then defeat the Copper Monstrosity — Minecraft Dungeons II Boss Guide again. Rematches in Minecraft Dungeons II hit harder than the story version of the fight, and this one is no exception — the Monstrosity brings its full electric kit, the conductive-status attacks, the electrified phase after its blast, and the revival stage that extends the fight past the first health bar.

Preparation

Treat this as an endgame-gear check at level 21. Poison damage is the answer here: the boss takes +50% from poison and resists lightning at -35%, so lightning builds that carried you through the region will struggle. Stock up on healing before the arena — the head slam and the charge both hit for the mid-20s to 30, and the copper cubes it summons after electrifying add pressure from the flanks.

Rewards

First completion rewards Stormcaller. There are no repeat-run rewards listed, but the quest exists to be re-run: it is the cleanest farm for the Monstrosity's drops at level 21. You must finish Wading Rainy Plains before it becomes available, and it pairs well with Recycling Your Monstrosity for a full Rainy Plains session.
