Updated Sunna’s full build.

Sunna (ZZZ) is one of the Physical characters with role. Sunna (ZZZ) is one of the S Rank characters in Zenless Zone Zero.

Sunna Build (ZZZ) is included in this guide, you can jump to Sunna Build (ZZZ) Here.

Sunna’s positioning is as a pure off-field character; she is almost never brought on-field to actively fight, and her actual combat operation is also very simple. You only need to use her Ex Special Skill and Ultimate; her other skills don’t need to be used.

First, let’s look at her Special Skill. In actual combat, her regular Special Skill is essentially useless. Next, I’ll show you her Ex Special Skill. When her energy reaches at least 70 points, she can consume 70 energy by holding down the Special Skill key to use her Ex Special Skill. Because the animation duration for her Ex Special Skill is quite long, don’t just tap it; you must hold down the key to ensure the entire Ex Special Skill sequence completes.

So, what are the effects of Sunna using her Ex Special Skill? It has three main functions:

Grants the entire team +1,050 ATK for 40 seconds. This ATK buff reaches its maximum value when Sunna’s own out-of-combat ATK reaches 3,500.
Opens an Ether Veil called “Delusion Reprise”. This Ether Veil grants the entire team an additional +50 ATK and increases the enemy’s Daze vulnerability multiplier by 30%, also lasting 40 seconds.
Triggers the next character’s Quick Assist.

These are all the functions of Sunna’s Ex Special Skill.

Now, let’s move on to her Ultimate. Its damage isn’t particularly noteworthy. The main point is that using her Ultimate provides area-of-effect healing for the entire team. The moment the Ultimate is cast, the entire team’s HP is increased by 2,950 points. This is the primary use of her Ultimate.

Additionally, Sunna has a passive ability that grants the entire team a certain amount of off-field DPS capability. When Sunna’s off-field special basic attacks, Ex Special Skill, Chain Attack, or Ultimate hit an enemy, they apply a debuff called “Cat’s Gaze” to that enemy. If we then switch to other Attack-type or Anomaly-type characters in the team and continuously attack an enemy marked with Cat’s Gaze, the mark will be detonated, dealing additional damage.

Characters in the Angelic Chord-ination state gain increased ATK equal to 30% of Sunna’s initial ATK, up to a maximum of 615 / 705 / 795 / 885 / 975 / 1,050 ATK. When Sunna’s initial ATK reaches 2,050 / 2,350 / 2,650 / 2,950 / 3,250 / 3,500, 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 175% / 200% / 225% / 250% / 275% / 300% ATK to enemies in an area.
• When triggered by an Anomaly character, deals the Agent’s Attribute DMG equal to 280% / 320% / 360% / 400% / 440% / 480% ATK to enemies in an area. This DMG is guaranteed to CRIT, and the CRIT DMG is increased by 90% / 100% / 120% / 130% / 140% / 150%.

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.
