Quick verdict

Worth pulling if you have Ye Shunguang or an Angels of Delusion team, since she's their most natural support with long-term ATK buffs and Ether Veil. Outside those teams she's pickier than generic ATK supports, and you have to build to ~3500 ATK to unlock her full utility, so she demands fairly heavy disc investment.

Stat targets

Core threshold: aim for ~3,500 INITIAL ATK on Sunna, because her Core Skill shares squad ATK equal to 30% of her initial ATK, capped at +1,050 ATK (per game8/lootbar) — below this the team buff falls short. Since she is the most energy-hungry of the supports, invest enough Energy Regen to reliably fire her EX Special every time she enters (M1 removes this bottleneck). Suggested main stats: Disc 4 ATK% (or Energy Regen) · Disc 5 ATK% · Disc 6 ATK% / Energy Regen. Substat priority: ATK% > flat ATK > Energy Regen. She does NOT need CRIT since she isn't a primary damage source. (numbers per game8 + lootbar; beyond the ATK/ER thresholds the rest is qualitative.)

Rotation & combos

1) ON ENTRY: use EX Special (Bubblegum Barrage) to grant the whole squad Angelic Chord-ination for 40s and trigger Quick Assist. 2) Chain the second EX Special (Special Photography Technique) while Angelic Chord-ination is active to raise Ether Veil: Delusion Reprise — +50 ATK to all squad members for 40s (per genshin-builds). 3) Quick-swap to your carry (Ye Shunguang / Aria / an Attack agent) so they hit the Cat's-Gaze-marked target for the bonus damage: Attack chars ~300% ATK, Anomaly chars ~480% ATK with guaranteed CRIT + 150% CRIT DMG (per lootbar). 4) When Decibel is full, cast the Ultimate (Smash It All!) to heal the squad and gain 6 Claw Sharpeners, then loop from step 1. Core idea: she's a short-stay support built around casting EX EVERY rotation to keep Ether Veil and the ATK buff from lapsing.

Mindscapes — how far is worth it?
M1 Worth it

Starting Energy is raised to 30 → she can fire her EX Special IMMEDIATELY on entry; and each time Cat's Gaze hits an enemy it shreds 7% of the target's DEF for 40s (per game8). For an energy-hungry support this is arguably the most valuable QoL cinema: it removes her first-rotation energy bottleneck and layers in a teamwide DEF shred.

M2 Worth it

'Feline Go-With-the-Flow': while Sunna stands inside any Ether Veil the whole squad gains +10% ATK and she generates 1 Claw Sharpener every 10s; it also LOWERS the hit count needed to trigger Cat's Gaze and boosts its trigger multiplier — +200% when an Attack character triggers it, +300% when an Anomaly character does (per game8). This is the real teamwide damage inflection and the ideal stopping point for most players who want power without whaling.

M3 Low value

'Transformation Apple': Basic, Dodge, Assist, Special and Chain Attack +2 levels. A flat numeric bump with no gameplay change — low value, a stepping stone to M4.

M4 Situational

'Delusion Investigation Team': when Sunna casts her Ultimate, the whole squad deals +18% DMG for 60s (per game8). A flat damage layer that's easy to keep up thanks to the long 60s window — a sensible bump but not a must-have; worthwhile if you're already passing through it toward M6.

M5 Low value

'Galaxy Tramway': again +2 levels to all skills, same as M3. Still just flat numbers, a bridge to M6 — low value.

M6 Worth it

'Hollow Big Bang': after Sunna uses her EX Special she enters a Focused Creation state for 8s — during it her attacks GUARANTEE CRIT, she takes 40% less damage, and Cat's Gaze is re-applied by consuming Claw Sharpeners (per game8/ldshop). A whale-tier ceiling: thicker debuff uptime plus a survivability layer, but most players stop at M2 and only those with spare resources aim straight for M6 (skipping the bland M3/M5).

Pros
  • Teamwide ATK buff scaling off her own initial ATK (up to +1,050 ATK) plus +50 ATK from Ether Veil — a thick damage floor for both Attack and Anomaly carries.
  • Cat's Gaze turns each carry hit into bonus damage: Anomaly agents get guaranteed CRIT + 150% CRIT DMG, a rare mechanic that lets anomaly teams tap into CRIT.
  • Broad support utility: her Ult heals the whole squad (~2,950 HP), and with Attack / same-faction allies she grants +30% Stun DMG Multiplier — sustaining the team while padding stun-window burst.
  • The best-fit support for Ye Shunguang and full Angels of Delusion teams (Aria, Nangong Yu) — Ether Veil ramps those carries into their strong states faster.
Cons
  • The most energy-hungry of the supports — her whole kit hinges on casting EX Special every rotation, so without Energy Regen the buffs lapse (M1 or an energy W-engine is nearly required).
  • Stat-demanding: needs ~3,500 initial ATK to unlock the full buff (the +1,050 ATK cap), which asks for heavy ATK disc farming — below the threshold the team visibly loses damage.
  • Her peak value is gated behind Attack / same-faction Angels of Delusion teams (her Additional Ability is conditional); outside those comps she's pickier than a generic ATK support.

Endgame mode fit
Shiyu Defense

In Shiyu Defense, Sunna's score follows the carry she enables — she shines most in single-target burst teams around Ye Shunguang or a full Angels of Delusion comp, where the +1,050 ATK, Ether Veil and Cat's Gaze all funnel onto one target for a fast in-window kill. Outside those tailored teams she's usable but her edge over a generic ATK support narrows. (qualitative; new agent, no stable score table yet.)

Deadly Assault

In Deadly Assault against multiple high-HP foes, Cat's Gaze turns every carry hit into bonus damage and her Ult's squad heal (~2,950 HP) helps survive the heavy waves — she's a reliable enabler for Anomaly (Aria) or Attack teams. The score leans on the carry, but her long 40s buffs suit this mode's drawn-out fights. (qualitative.)

Core Skill2

Core Passive: Cuteness Is Justice
Characters in the Angelic Chord-ination state gain increased ATK, equal to 30% of Sunna's initial ATK, up to a maximum of 525 ATK. When Sunna's initial ATK reaches 1,750, the ATK bonus granted to all squad members reaches its maximum. When attacks from Basic Attack: Naughty Cat Spotted, EX Special Attack: Bubblegum Barrage, EX Special Attack: Special Photography Technique, Chain Attack: Don't Mess With the Cat, or Ultimate: Smash It All! hit an enemy, apply Cat's Gaze to the target for 12s. While Sunna is the currently active character, the duration of Cat's Gaze is continuously refreshed. Some normal enemies affected by Cat's Gaze show reduced aggression toward Sunna. When Attack or Anomaly characters in the squad continuously land attacks on enemies affected by Cat's Gaze, Cat's Gaze is triggered and removed: When triggered by an Attack character, deals the Agent's Attribute DMG equal to 150% of ATK to enemies in an area. When triggered by an Anomaly character, deals the Agent's Attribute DMG equal to 240% of ATK to enemies in an area. This DMG is guaranteed to CRIT, and the CRIT DMG is increased by 80%. DMG dealt by Cat's Gaze is treated as DMG dealt by the triggering Agent. When multiple enemies on the field have Cat's Gaze, only the primary attack target's Cat's Gaze is triggered. Upon triggering, Cat's Gaze is removed from all enemies on the field. When an enemy is Stunned, the number of attacks required to trigger Cat's Gaze is significantly reduced.

Additional Ability: Daydreamer's Counterpoint
