The Monarch

For the complete strategy, see the full boss guide: The Monarch.

The Monarch is a late-game sculk boss fought in the sculker nest, deep in the Sift. It brings 1,400 health, hits of up to 18, poise of 600, and 30 souls dropped on defeat. Its moveset mixes a flying attack sequence (9 physical), a charge (15 physical), and a heavy melee strike (18 physical).

Its signature mechanic is the summon: it roars and calls two sculk slashers and two sculk mages, and it cannot summon again while they live. Once it has lost a quarter of its health, it conjures the Monarch's Echo, a spectral clone with the same attacks. The critical rule: focus the Monarch, not the Echo — defeating the Monarch ends both.

You fight it in "Wrath of the Sculkers" and the "End of the procedural dungeon" boss room, both in the Ravines. Use jump attacks, revive downed teammates together, and read the full boss guide before you descend.
