What Makes Sunna Special
Sunna stands out as a rotation specialist who makes team rotations feel incredibly smooth. She fits into many team compositions and provides multiple benefits at once. Her special ability called Angel’s Accord turns her into a powerful setup character who creates opportunities for your main damage dealers.
When Sunna uses her EX Special Attack, she enters Angel’s Accord state and triggers Bubble Pop hits. She opens Fantasia Encore (Ether Veil) right before her heavy attack lands. When that heavy attack connects, it instantly triggers Quick Assist, pulling your carry into battle already inside the Veil with no downtime.
Her Cat’s Gaze marking system allows Attack and Anomaly characters to detonate marks for extra attributed damage. Attack characters deal attribute damage equal to their attack stat when detonating marks. Anomaly characters deal similar damage with guaranteed critical hits and increased critical damage. These marks detonate faster on stunned enemies, making her perfect for burst damage windows.
Best W-Engines for Sunna
Choosing the right W-Engine greatly improves Sunna’s performance. Here are the top options:
| W-Engine | Rarity | Why It Works |
| Cuteness is Justice | S-Rank | Her signature weapon with highest support value. Provides 25% damage and 25% attack to all squad members after activating EX Special Attack twice. Fits perfectly into her core rotation. |
| Weeping Cradle | S-Rank | Strong alternative with decent buffs. Provides up to 20.7% damage bonus for 3 seconds. Timing can be tricky but effective when mastered. |
| Punishment | A-Rank | Best budget option. Increases all units’ damage against struck targets by up to 20%. Stacks further over time up to maximum 19.8% additional increase. Has energy regeneration while off-field. |
| Bashful Demon | S-Rank | Provides critical rate buff against enemies weak to Physical. Only effective when facing three Physical-weak enemies. Situational but strong in right scenarios. |
Best Drive Discs for Sunna
Sunna has one clear best Drive Disc set with solid backup options:
Best Choice: Moonlight Lullaby (4-piece) + Energy Regen or ATK (2-piece)
The 4-piece Moonlight Lullaby provides 18% damage bonus for 25 seconds to all squad members after using her EX Special Attack. This set works perfectly with Sunna’s kit since she constantly uses EX Special Attacks to trigger her support state.
The 2-piece sets should focus on Energy Regeneration or Attack percentage. Energy regeneration helps Sunna charge her abilities faster and maintain buff uptime. Attack percentage increases her personal damage and strengthens her Cat’s Gaze mark detonations.
Alternative Option: Astral Voice (4-piece) + Physical DMG or CRIT DMG (2-piece)
If someone else on your team already uses Moonlight Lullaby, equip Astral Voice as your 4-piece. This set needs testing to see if stacks can be maintained effectively enough to outperform Moonlight Lullaby. The 2-piece Physical Damage or Critical Damage sets can increase Sunna’s personal damage output.
Drive Disc Stats Priority
Here’s what stats you should aim for on each Drive Disc piece:
| Disc Slot | Main Stat | Priority Substats |
| Slot 4 | ATK% | ATK% > Energy Regen > CRIT Rate |
| Slot 5 | ATK% | ATK% > Energy Regen > CRIT Rate |
| Slot 6 | ATK% | ATK% > Energy Regen > CRIT Rate |
Substat Priority: ATK% > Energy Regen > CRIT Rate
Attack percentage is your most important stat because it strengthens both her support buffs and her mark detonation damage. Energy regeneration comes second because more energy means smoother rotations and more consistent Veil triggers. Critical stats help if you want Sunna to deal personal damage during her support windows.
Skill Priority
Level up Sunna’s skills in this order:
- Core Skill
- Special Attack
- Basic Attack
- Assist
- Chain Attack
- Dodge
The Core Skill is where her real support value scales. It boosts the mark and pop package so your carry gets more consistent credited pop damage. It also strengthens her Veil-related benefits that turn normal stun windows into high damage opportunities.
How to Play Sunna
Start battles by using Sunna’s EX Special Attack to enter Angel’s Accord state. This triggers Bubble Pop and opens Fantasia Encore. When the heavy attack lands, it instantly pulls your main damage dealer into battle through Quick Assist.
Rotate between your two main damage dealers while Sunna stays off-field. Her cat companion will automatically maintain Cat’s Gaze marks on enemies by consuming Attack Points. Each time your team triggers or extends Ether Veil, Sunna gains 3 Attack Points to fuel this system.
Focus on detonating marks during stun windows for maximum damage. Stunned enemies allow marks to detonate faster, creating explosive burst damage. Your Attack or Anomaly characters will automatically detonate marks when landing heavy attacks on marked enemies.
Best Team Synergies
Sunna works exceptionally well with:
- Attack Agents – Ye Shunguang and other Attack types benefit from her critical damage buffs and clean rotation windows
- Anomaly Agents – Aria (same faction) and other Anomaly types gain Anomaly Mastery buffs and guaranteed critical hits on mark detonations
- Angels of Delusion faction members – Natural synergy with faction teammates like Aria
With proper building and team composition, Sunna becomes an essential support character in Zenless Zone Zero. Her universal buffs, smooth rotations, and unique marking system make her valuable for any team strategy focused on maximizing damage during burst windows.
