Recommended Substats

Defense %HP %DMG Reduction Rate

Ermes is an SSR Defense unit who tanks off Defense scaling and Kiss stickers. Hypersonic Harpoon and License for Revenge reposition or duplicate-burst while Shields and Damage Res stack from Ultimates and Duplicated Form. She also shares Shields to nearby allies, so she is more than a selfish wall. A+ Defense for sticky frontlines — prioritize her when you want Defense-based damage plus team shielding.
