About Oni

Oni is a Mythical-rarity race in Sailor Piece, providing +65% max hp, +55% damage, +20% damage, +10% damage reduction. Its combined bonuses make it a top-tier choice relative to other races of the same rarity, and its stat spread pairs naturally with builds that prioritise tank / infinite tower and boss damage.

To obtain Oni: Race Rerolls are earned from bosses and occasional event rewards. Because it is Mythical-rarity, expect 150-400 attempts on average before it rolls for the first time, so budget inventory accordingly before spending a reroll stack.

In the current meta, Oni slots into builds that want tank / infinite tower, boss damage. Pair it in the Build Calculator with a complementary clan, race, and trait to verify that the combined total damage, HP, and utility stats exceed the threshold you need for the content you're grinding.
