Best Nilou Build for 2026

Nilou does not deal meaningful personal damage, and that is fine - she is the enabler of one of the strongest AoE archetypes in the game. Her passive replaces normal Bloom cores with Bountiful Cores that detonate almost instantly and deal damage in a larger radius. Critically, this passive only works when the party contains Hydro and Dendro characters exclusively, so team building around her is a hard constraint rather than a preference. Her contribution scales with nothing but HP: every 1,000 HP above 30,000 increases Bountiful Core damage, capping at roughly 74,444 HP for the maximum bonus. This means her entire build is HP% main stats with HP% substats, and her weapons are judged almost entirely on how much HP they give (Key of Khaj-Nisut is far ahead of everything else). The standard Nilou Bloom rotation is counterintuitive: she opens with E x3 (Sword Dance -> Whirling Steps -> Luminous Illusion) to set up her Hydro ring, then swaps out and lets the Dendro and Hydro appliers generate cores. The on-field driver should be the Hydro healer (Kokomi or Barbara) so Bloom self-damage is healed, with Nahida providing the Dendro aura. Where she struggles: Nilou is completely inflexible. Any Pyro, Electro, Cryo, or Anemo teammate disables her core passive, and against single-target bosses Bountiful Core teams are much weaker than Hyperbloom or traditional carries.
