Who is ONiON?

ONiON is a 3-star Mineral-afflatus character whose tag lists DPS and Debuff, but whose kit satisfies neither role adequately. Her incantations deal extra damage when targets are under Stats Down, Neg Stats, or Control status — similar to Leilani — but without Leilani's Moxie generation or competitive damage multipliers. She also has minor team damage reduction and a self-[Taunt] option that conflicts with a damage-oriented kit. Low base stats compound the issue. ONiON is widely considered the weakest unit in the game and is not recommended for serious investment.

Kit Summary

Conditional bonus damage

Both incantations deal extra Reality DMG when the target is under a debuff or control status — the only offensive hook in her kit.

Hybrid tank-gestures

Minor team damage reduction and access to [Taunt] give a defensive veneer without the stats to back it up, creating a confused identity between carry and tank.

Build Guide

🔮 Best Relic / Echo Set

Not recommended for investment. If used, ATK resonance to get any damage value from her incantations.

Best Light Cone / Weapon

His Bounden Duty: High base ATK plus 12% DMG Bonus compensates slightly for her low base stats — the best available option if she must be used.

👥 Best Teams

No recommended team composition. She can theoretically slot into a debuffer team for bonus damage but is outperformed by any alternative at the same role.

F2P Verdict

SkipPatch 3.4

Considered the weakest unit in the game by Prydwen; no meaningful use case in any team composition at any stage of the game.

Available from the standard gacha pool at 3-star rarity. Do not invest resources. She occupies a roster slot but contributes nothing a better character cannot do more effectively.

Frequently Asked Questions

Is ONiON really the worst character in the game?

According to Prydwen, yes — her kit tries to be a debuff-enabled carry and a tank simultaneously without the stats or mechanics to succeed at either, leaving her without a viable niche.

Is there any situation where ONiON is useful?

Not meaningfully. Even in low-rarity challenge content, Leilani or Darley Clatter fill offensive and support roles more effectively at the same investment level.
