Sunna Agent Overview
| Agent Overview |
 | Rarity | S Rank |
| Attribute | Physical |
| Specialty | Support |
| Combat Role | Support DPS Hybrid |
Sunna is a Physical Support Agent who focuses on teamwide ATK buffs, Ether Veil, and a unique debuff called Cat’s Gaze. Her kit is built around buffing the entire squad. By using her Special and EX Special Attacks, Sunna applies Angel’s Accord and opens Ether Veil, granting long-duration ATK bonuses that scale with her initial ATK. She also marks enemies with Cat’s Gaze, which can be triggered by teammates to deal guaranteed critical Attribute Anomaly.
Sunna Skill Priority
Below are the best skill priorities for Sunna in Zenless Zone Zero:
| Skill | Priority | Reason |
Core Skill 
| ★★★★★ (Top) | Sunna’s most important skill, as it defines the strength of Angel’s Accord, her main teamwide ATK buff. Since this buff scales from her initial ATK, upgrading the Core Skill is essential for maximizing her support value. |
Special Skill 
| ★★★★★ (Top) | Central to Sunna’s support role. These skills apply Angel’s Accord, open Etherveil, trigger Quick Assists, and provide full invulnerability. Leveling them improves buff uptime and rotation consistency. |
Chain Attack 
| ★★★★★ (Top) | Deals heavy damage, triggers Quick Assist, and contributes to burst windows while keeping Sunna safe. Useful for maintaining pressure and supporting team damage flow. |
Basic Attack 
| ★ (Low) | Mostly used situationally, as Sunna spends limited time on-field. |
Assist 
| ★ (Low) | Low return on investment. |
Dodge 
| ★ (Low) | Sunna has built-in invulnerability on key skills |
Sunna Best W-Engines
Sunna scales primarily with ATK and Energy Regeneration. Sunna has a wide set of viable W-Engine options. Any W-Engine that provides Energy Regen, ATK, or teamwide buff effects works well with her kit, as these directly strengthen Angel’s Accord and Etherveil uptime. Obviously, Sunna’s signature W-Engine is her best-in-slot option, offering superior energy recovery and powerful teamwide damage buffs that align perfectly with her support role. To maximize Sunna’s buff duration and overall team amplification, obtaining her signature W-Engine is strongly recommended.

Sunna Best Drive Disc Sets
Sunna performs best with Moonlight Lullaby (4-PC). Moonlight provides high Energy Regeneration and a long-duration teamwide DMG bonus, which is easy to maintain through EX Special and Ultimate cast.
Astral Voice (4-PC) is a solid alternative for teams that rely heavily on Quick Assists. It offers a strong damage buff for quick assist teams. Though its uptime is less consistent compared to Moonlight Lullaby.
| Best Choice |
Moonlight Lullaby | - 2 Pc-Set Bonus - Energy Regen +20%
- 4 Pc-Set Bonus - When the equipper is a Support character and uses an EX Special Attack or Ultimate, the DMG dealt by all squad members increases by 18% for 25s. Repeated triggers reset the duration. Passive effects of the same name do not stack.

Sunna Best Teams
Sunna pairs best with DPS Agents that scale with ATK. She is also very strong in Anomaly teams, where Cat’s Gaze can be triggered efficiently and deal high guaranteed critical damage. Outside of Anomaly-focused setups, Stun Agents become more important, as frequent stuns help Cat’s Gaze trigger faster and improve overall team damage consistency.

Sunna Best Mindscapes
| M1 - Loneliness Corruption Symptoms |
- Rating - ★★★★ (Very Good)
- Effect
- When Sunna enters the battlefield, she gains 15 Energy. In Investigation Zone Mode, this effect can trigger once every 180s.
- When Cat's Gaze triggers and hits an enemy, the target's DEF is reduced by 7% for 40s, stacking up to 3 times. The duration of each stack is calculated separately.
- Reason - Adds Energy on entry and introduces a stacking DEF reduction tied to Cat’s Gaze. This improves team damage output and scales well in longer fights, making it Sunna’s most valuable early Mindscape.
|
| M2 - Feline Go With the Flow |
- Rating - ★★★★★ (Amazing)
- Effect - While Sunna is within any Ether Veil, all squad members gain 10% ATK and she gains 1 Claw Sharpener every 10s. Cat’s Gaze requires fewer hits to trigger, and its DMG Multiplier is increased by 200% when triggered by Attack characters and 300% when triggered by Anomaly characters.
- Reason - This Mindscape significantly strengthens Sunna’s core mechanics. It boosts team ATK, improves Cat’s Gaze reliability, and massively increases Cat’s Gaze damage, especially in Anomaly teams.
|
| M3 - Transformation Apple |
- Rating - ★ (Low)
- Effect - Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2
- Reason - Skill level increase only.
|
| M4 - Delusion Investigation System |
- Rating - ★★★★ (Very Good)
- Effect - When Sunna uses her Ultimate, all squad members deal 18% increased DMG for 60s.
- Reason - Provides a long-duration, teamwide damage buff.
|
| M5 - Galaxy Tramway |
- Rating - ★ (Low)
- Effect - Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2
- Reason - Meh. Same reason as M3
|
| M6 - Hollow Big Bang |
- Rating - ★★★★★ (Top-Tier)
- Effect
- When Sunna uses an EX Special Attack, she enters the Focused Creation! state for 8s.
- While in the Focused Creation! state, all attacks Sunna performs are guaranteed to CRIT, and her CRIT DMG increases by 0.03% of her initial ATK, up to a maximum of 105%.
- While in the Focused Creation! state, Sunna's Anti-Interrupt Level is increased, and DMG taken is reduced by 40%.
- While in the Focused Creation! state, Sunna can trigger Cat's Gaze, its DMG being calculated using Attack Agent rules. If Cat's Gaze is triggered while Sunna has a Claw Sharpener, the Claw Sharpener is immediately consumed, and Cat's Gaze is reapplied to the enemy.
- While in the Focused Creation! state, DMG dealt when any squad member triggers Cat's Gaze increases by 50%.
- Reason - This Mindscape dramatically raises Sunna’s ceiling. It turns her into a powerful support–DPS hybrid during Focused Creation!. Massively boosts Cat’s Gaze damage for the entire team, enabling extremely high DPS potential.
