Crimson Malefact

Also known as Koo's Nushi Form

The hostile Nushi form taken by Koo and identified by the combat encounter as Crimson Malefact. The trophy description calls the same battle Koo's Nushi form, so both names are preserved on one page instead of being treated as separate monsters.

Recommended strategy

Emma fights this encounter without Koo, removing the partner commands used in most Nushi battles. Equip strong defensive armor and carry enough arrows or bolts to maintain pressure when approaching is unsafe. Published guidance recommends Poison buildup with the Hunter's Sword and Poison ammunition, but the same page labels the elemental weakness as Water; because those claims conflict, the Weakness field remains Not yet verified. In phase one, learn the four-hit sequence and parry or block through its end before countering. Dodge the backhand spring and rock throw, then use only a short punish so Emma can reposition. At roughly half health, the second phase adds more aggressive ranged flower attacks resembling Koo's Seeds and Bloom skills. Preserve ammunition for this phase and use Entanglement Overdrive only after an attack or completed combo. The safe plan is sustained status pressure, disciplined defense, and short counters rather than assuming an unverified weakness.
