Sunna Agent Profile
Sunna is a support enabler who specializes in buffing Attack and Anomaly DPS characters through Fever, Mesmerized mark detonations, and Ether Veil: Idol. Her value comes from amplifying teammates’ burst damage rather than dealing damage herself.
Sunna applies the Mesmerized mark to enemies through most of her attacks. While she is on-field, the mark is continuously refreshed. When Attack or Anomaly teammates land heavy attacks on marked enemies, Mesmerized detonates, dealing AoE Attribute DMG. Detonations triggered by Anomaly characters are guaranteed to CRIT with greatly increased CRIT DMG, making Sunna especially strong in Anomaly-focused teams. Mesmerized also detonates faster during enemy Stun windows.
Her EX Special Attacks activate Fever and Ether Veil: Idol, providing powerful team-wide buffs that scale with Sunna’s ATK. Depending on team composition, Ether Veil increases Stun DMG multiplier, CRIT DMG, or Anomaly Proficiency, allowing Sunna to flexibly support both Attack and Anomaly lineups.
In practice, Sunna’s gameplay revolves around maintaining Mesmerized, triggering Fever, and opening Ether Veil: Idol before allies’ burst phases. She functions as a burst-focused support and damage amplifier, excelling at enhancing stun windows and maximizing team damage output.
