Sunna ZZZ Kit & Best W-Engine Build (2.6)

When analyzing the full Sunna ZZZ Kit, it is immediately clear that she isn’t your typical “press E and forget” Support like Soukaku or Nicole.

As a member of the new Angels of Delusion faction, her mechanics are frankly… a lot. She summons a cat named Bubblegum, manages a resource called “Claw Sharpeners,” and forces you to pick the perfect Sunna W-Engine just to hit that demanding 3,500 ATK threshold.

Is she worth the headache? After reviewing hours of gameplay footage from analysts like iamrivenous and The Sacred Spear, our answer is a resounding YES, but with a catch.

You should absolutely pull if you main Yixuan (Ye Shunguang) or plan to get Aria (the upcoming Anomaly unit) since she is their best-in-slot partner.

However, you might want to skip if you strictly play simple “Stun-focused” teams like Lycaon/Ellen and hate managing complex rotations.

Sunna ZZZ Kit Breakdown

If you’re searching for a real Sunna ZZZ kit breakdown, this is the one that explains everything without putting you to sleep.

Sunna in Zenless Zone Zero is a burst-support specialist built around three pillars:

1. Cat’s Gaze (her detonation mechanic)
2. Claw Sharpener stacks (resource engine)
3. Angelic Chord-ination + Ether Veil (team amplification phase)

Look, she’s a damage multiplier in disguise.

Basic Attack

1. Basic Attack

Sunna performs up to four forward hammer strikes, dealing Physical DMG. Nothing fancy here, it’s mainly for refreshing Cat’s Gaze when needed.

2. Basic Attack – Naughty Cat Spotted (Off-Field Passive)

Okay, this section feels more interesting when:

• Sunna is off-field
• No enemy currently has Cat’s Gaze

Bubblegum (her companion) consumes 1 Claw Sharpener and automatically attacks. Important details:

• Bubblegum inherits Sunna’s initial ATK
• Sunna can hold up to 6 Claw Sharpeners
• Gains 2 stacks when Ether Veil activates
• Gains 1 stack when Anomaly is applied (10s cooldown)

Sunna keeps pressure even when she’s not on the field. She maintains Cat’s Gaze uptime through Bubblegum as long as you manage Claw Sharpeners properly.

If you ignore stack management, her rotation becomes clunky.

Dodge Kit

1. Dodge – Can’t Hit Me

Quick dash with full invulnerability.

2. Dash Attack – Skyward Hammer

Launches enemies into the air with Physical DMG.

3. Dodge Counter – Delusion Strikeout

Perfect Dodge → multi-hit hammer combo. Fully invulnerable during execution.

You won’t keep her on-field long, but when you do, she’s extremely safe.

Assist Skills

Sunna’s Assist kit actually adds serious value during burst windows.

1. Quick Assist – Sonic Beatdown

Triggered when the active character is launched. Multi-hit hammer attack with invulnerability.

2. Defensive Assist – Stage Fright

Parries enemy attacks → deals massive Daze. This is huge for stun setups.

3. Assist Follow-Up – Jump Training

After Defensive Assist, she leaps forward, dealing heavy Physical DMG. So yes, she contributes meaningful Daze and burst setup even outside her EX cycle.

Special Attack

Now we get to the real mechanics.

1. Special Attack – Star Shooter

Shoots Bubblegum forward to deal Physical DMG and bring it into combat. This is your basic Bubblegum activation.

2. EX Special – Bubblegum Barrage

This is where things start cooking. When activated:

• Throws Bubblegum
• Applies Angelic Chord-ination for 40s
• Triggers Quick Assist on a heavy hit
• Fully invulnerable during cast

This state is the gateway to her main buff cycle.

3. EX Special – Special Photography Technique

While Angelic Chord-ination is active:

• Perform a coordinated attack with Bubblegum
• Activates Ether Veil: Delusion Reprise
• Grants +50 ATK to all squad members for 40s
• Can only be used once per Angelic Chord-ination cycle

This is the burst amplifier. Ether Veil boosts team ATK and enhances stun-phase damage scaling.

You want this active right before your DPS unloads everything.

Chain Attack – Don’t Mess With the Cat

Triggered during stun sequences.

• Massive Physical DMG
• Triggers Quick Assist
• Full invulnerability

This helps reapply Cat’s Gaze and extend burst flow.

Ultimate – Smash It All!

When Decibel is maxed:

• Multi-hit hammer combo
• Bubblegum explosion
• Gain 6 Claw Sharpeners
• Triggers Quick Assist
• Restores HP to all squad members
• Fully invulnerable

That 6-stack gain is extremely important.

It resets your Claw Sharpener engine so you can maintain Cat’s Gaze uptime longer.

Core Mechanic

Now we talk about the real reason Sunna exists. You apply this automatically using her EX Special or Ultimate.

The magic happens when your DPS triggers the mark. The damage scaling changes based on your agent’s role:

Triggering Agent	Damage Multiplier	Bonus Effect
Attack Agents	300% ATK	Standard Attribute DMG.
Anomaly Agents	480% ATK	Guaranteed CRIT + 150% Crit DMG.

The damage calculation uses the Triggering Agent’s Stats, NOT Sunna’s. This is why Sunna is a “Damage Amplifier.”

She borrows your DPS’s high stats to create massive explosions. So, the stronger your DPS, the stronger Sunna becomes

Claw Sharpener Stacks

Sunna gains stacks when:

• Ether Veil activates
• An anomaly is applied
• Ultimate grants 6 stacks

When Cat’s Gaze expires, Bubblegum consumes 1 Claw Sharpener to reapply it. So the gameplay loop becomes:

Inflict Cat’s Gaze → Trigger detonation → Maintain stacks → Reapply → Repeat.

If you mismanage stacks, Cat’s Gaze falls off, and you lose burst uptime.

Angelic Chord-ination

When EX Special activates Angelic Chord-ination, Sunna’s Core Passive kicks in: Teammates gain ATK equal to 30% of Sunna’s initial ATK (Capped at 1,050 ATK). Which means:

You want ~3,500 ATK on Sunna. That’s the breakpoint for maximum team scaling.

Below that, her buff isn’t fully optimized.

Ether Veil: Delusion Reprise

When activated:

• Team gains flat +50 ATK
• Increases burst synergy
• Boosts Daze vulnerability

This is your “go now” signal. Activate this before your DPS combo during stun windows.

How to Play Sunna (Real Rotation Logic)

These are the clean flow:

1. Swap in Sunna
2. Use EX Special (Angelic Chord-ination)
3. Trigger Special Photography Technique (Ether Veil)
4. Apply Cat’s Gaze
5. Swap to DPS
6. Burst during stun
7. Maintain Claw Sharpener stacks
8. Repeat

She’s a setup character. She prepares the stage. So, yeah, your DPS performs the finale.

Best Sunna ZZZ Build Kit in Complete

Sunna is an off-field Physical Support who buffs team damage, boosts ATK through her Core Skill, and enables your main DPS to cook absolutely.

So we built her around fast energy generation, maximizing ATK scaling, and boosting team-wide damage.

Best W-Engine for Sunna ZZZ

Sunna has one major weakness, which is energy hungry. If she can’t cast EX consistently, her buffs fall apart.

So your W-Engine choice is everything.

1. Sunna’s Signature W-Engine: Thoughtbop

This is Sunna’s best-in-slot. Period. Why is it insane?

• Boosts Energy Regen while off-field (exactly where she lives).
• After using EX Special (Physical DMG), the whole squad gains:
  • DMG increase (stackable up to 2x)
  • At 2 stacks → extra ATK boost
• Only one instance per squad (so don’t double it).

Thoughtbop Stats (at Level 0–Max)

• Base ATK: 48 → 713
• Advanced Stat: Energy Regen (24% → 60%)

That Energy Regen stat alone makes her rotation smoother.

Materials to Fully Upgrade Thoughtbop

• Support Component ×4
• Specialized Support Component ×30
• Reinforced Support Component ×32
• Denny ×400,000

If you have it? Use it. No debate.

2. Weeping Cradle (Punishment)

If you don’t have her signature, this is your next best bet, because:

• Off-field Energy Regen: +0.6/s
• When she hits enemies → increases team DMG against that target
• The buff ramps up over time (up to ~20% total bonus)
• Re-trigger refreshes the ratio but not the ramp amount

It’s slightly more conditional than Thoughtbop but still very strong for boss-focused comps.

3. Kaboom the Cannon

A more accessible option. It can affect:

• When any ally hits an enemy:
  • All allies gain ATK (2.5% per stack, up to 4 stacks)
• Each ally contributes stacks separately

It’s consistent, easy to maintain, and good for multi-character rotation teams.

Best Drive Discs for Sunna

Sunna’s discs should amplify her role as a pure buffer. Remember, her ATK determines how strong her team-wide buff becomes.

Target: 3,500 Initial ATK. Then, you must combine 4-Pc Moonlight Lullaby + 2-Pc Astral Voice

Moonlight Lullaby (4pc):

• Energy Regen bonus
• Team DMG increases after EX usage

Perfect synergy with her EX spam rotation.

Astral Voice (2pc):

• ATK bonus
• Helps reach 3,500 ATK cap

This setup balances Energy + ATK scaling

Main Stat Priority

Sunna scales off ATK and wants consistent EX uptime.

Slot Priorities:

• Slot 4: ATK%
• Slot 5: ATK%
• Slot 6: Energy Regen

If Energy feels fine already, you can double down on ATK%.

Substat Priority

1. ATK%
2. Flat ATK
3. Energy Regen
4. HP% (minor survivability)

She does not care about Crit. She is not your DPS. Let her live her supportive life.

Skill Priority

Level these in this order:

Skill	Priority	Why
Core Skill	Max First	This boosts her ATK buff and Cat’s Gaze effect. Her entire identity lives here.
Special Attack	Max ASAP	Core part of her kit and buff activation.
Chain Attack	High	Improves Ultimate healing and overall utility.
Assist	Medium	Helps for Defensive Assist Daze value.
Basic Attack	Skip	She shouldn’t stay on-field long.
Dodge	Skip	Not meant for extended field time.

Short version? Core > Special > Chain > Assist > Ignore the rest.

Sunna’s ZZZ Mindscape Cinema

Sunna’s Mindscape Cinema upgrades turn her from a strong off-field buffer into a team-defining enabler, and at higher levels, even a legitimate Sub-DPS.

Below is a clear breakdown of what each key Cinema level does and whether it’s worth your pulls.

Recommended Stopping Point

Cinema	Rating	Why It’s Strong
M1 – Loneliness Corruption Symptoms	★★★★★	Best value power spike
M2 – Feline Go-With-the-Flow	★★★★☆	Excellent team-wide scaling
M4 – Delusion Investigation Team	★★★☆☆	Long-duration team buff
M6 – Hollow Big Bang	★★★★☆	Turns her into a Sub-DPS

Recommended Team Compositions for Sunna ZZZ

Sunna is a buff-centric Support who thrives in teams that can capitalize on ATK buffs, explode during stun windows, and trigger her Additional Ability (requires specific team conditions like Attack-type synergy).

Based on testing in Shiyu Defense and Deadly Assault, here’s how her best teams stack up.

Team Ranking (Score-Based)

Team Name	Composition	Shiyu Score	Verdict
The Golden Trio	Sunna + Ye Shunguang + Dialyn	43,700	GOD TIER (Tier 0)
Double Support	Sunna + Ye Shunguang + Astra Yao	40,100	S-Tier (Glass Cannon)
Soldier’s Blaze	Sunna + Soldier 11 + Anby	38,900	A-Tier (Stable & Reliable)
The “Trap”	Sunna + Yuzuha + Miyabi	37,000	B-Tier (Synergy Issues)
F2P Physical	Sunna + Corin + Dialyn	23,000	Great Budget Option

1. Sunna + Ye Shunguang + Dialyn

Team Roles:

• Main DPS: Ye Shunguang
• Stunner: Dialyn
• Support: Sunna

Sunna’s EX Special interaction (Selfie Mode mechanic) can instantly refill a huge portion of Ye Shunguang’s resource bar.

This eliminates Ye Shunguang’s downtime, the single biggest weakness in her kit.

Rotation looks like this:

Dialyn Stuns → Sunna applies Cat’s Gaze → Ye Shunguang detonates during stun with boosted multipliers

The results are massive burst windows that outscale every other tested lineup.

If you own Ye Shunguang, Sunna is borderline mandatory. The damage gap between this comp and the non-Sunna versions is enormous (~5,000-point difference).

This is Sunna’s true Tier 0 environment.

2. Sunna + Ye Shunguang + Astra Yao

Team Roles:

• Main DPS: Ye Shunguang
• Support 1: Sunna
• Support 2: Astra Yao

Strengths

• Extremely high ATK stacking
• Massive burst during short damage windows
• Very fast front-loaded damage

Weaknesses

• No dedicated stunner
• Lower consistency against tanky enemies
• Can feel fragile.

3. Sunna + Soldier 11 + Anby

Team Roles:

• DPS: Soldier 11
• Stunner: Anby Demara
• Support: Sunna

Why It Works

• Classic Attack + Stun + Support structure
• Stable rotations
• Easy to execute

Downsides

• Doesn’t abuse Sunna’s resource feeding mechanic
• Lower ceiling than Yin Guang comp.

4. F2P Physical Teams (Budget Friendly)

1. Option A: Sunna + Corin + Dialyn

• DPS: Corin Wickes

Corin’s rapid hits trigger Cat’s Gaze explosions effortlessly. Sunna buffs her massive Chain Attack windows extremely well.

This team proves Sunna can revive older Physical units.

2. Option B: Sunna + Billy + Dialyn

• DPS: Billy Kid

Slightly weaker than Corin in single-target, but excellent for AoE-heavy content. Sunna’s ATK buffs make Billy’s Ultimate hit noticeably harder.

To wrap it up, Sunna’s Kit in ZZZ is an absolute powerhouse, but only if you commit to building her properly.

She’s not a plug-and-play support you can leave half-finished. If you’re not reaching 3,000+ ATK, her buffs will feel underwhelming, and you won’t unlock the explosive value she’s designed to provide.

Overall rating? S-Tier in optimized Physical/Anomaly teams, and a strong A-Tier as a general support. In the right setup, she defines the entire damage window.
