Sunna Best Build in ZZZ 2.6: 3,500 ATK Goal, Cat’s Gaze, Ether Veil

🎵 Sunna Is a “Buff Engine” Who Turns Your Carry Into the Show

Sunna isn’t just a stat stick — she’s a tempo controller. Once you build her to the 3,500 ATK breakpoint, she stops feeling like “a Support who presses EX sometimes” and starts playing like a buff loop you maintain: refresh Angelic Chord-ination, drop Ether Veil: Delusion Reprise, and keep Cat’s Gaze cycling so your Attack/Anomaly carry gets paid every time the enemy gets Stunned or pressured.

🧾 Sunna Profile Snapshot

• Rarity: S-Rank

• Attribute / Specialty: Physical / Support

• Faction: Angels of Delusion

• Ability Triggers: Works best with Attack Agents and Angels of Delusion teams

• Strengths: Big squad ATK buffs, Cat’s Gaze bonus damage, Ultimate healing, easy kit, F2P W-Engines exist

• Weaknesses: Wants Aria to function in Anomaly teams, and her kit doesn’t pair well with Rupture units

🧠 What Sunna Actually Does (In Plain English)

1) Angelic Chord-ination = your long buff window (40s)

• Triggered by EX Special Attack: Bubblegum Barrage

• It’s the “on” switch that enables her stronger EX follow-up and starts the rhythm of her play

2) Ether Veil: Delusion Reprise = your “performance stage” ATK layer

• Triggered by EX Special Attack: Special Photography Technique

• While it’s active, the whole squad gains additional ATK (flat +50 ATK in the text you provided), and it also enables a key synergy for certain Attack cores via her Additional Ability

3) Cat’s Gaze = your payoff detonator

• Applied when specific Sunna hits land (Core lists: Basic Naughty Cat Spotted, EX Barrage, EX Photography, Chain, Ultimate)

• Detonates when Attack or Anomaly characters keep hitting the marked enemy:

  • Attack trigger: Attribute damage based on 150% ATK (upgraded versions scale higher)

  • Anomaly trigger: Attribute damage based on 240% ATK, guaranteed CRIT with bonus CRIT DMG (upgraded versions scale higher)

• Huge rule: When it triggers, it’s removed from all enemies, and only the primary target is detonated if multiple are marked

• When an enemy is Stunned, it takes far fewer hits to trigger (meaning Cat’s Gaze becomes “faster money” during Stun windows)

🧰 Best Sunna Build (Support) — The One Build That Matters

✅ Support Build Core

• Best W-Engine: Thoughtbop

• Drive Discs: Moonlight Lullaby (4-pc) + Astral Voice (2-pc)

• Main Stats:

  • Disc 6: Energy Regen or ATK

  • Disc 5: ATK

  • Disc 4: ATK

• Substats: ATK, then CRIT Rate / CRIT DMG (you’re not chasing personal DPS first — you’re stabilizing buff uptime and Cat’s Gaze reliability)

The two breakpoints to respect

• 1,750 ATK: caps the basic Core buff (525 ATK cap in your text)

• 3,500 ATK: unlocks the maximum Core scaling at endgame and gives her Energy Regen support behavior for smoother EX usage
  Practical takeaway: Build ATK until 3,500 feels real, then decide whether Disc 6 needs Energy Regen or you can stay ATK.

⚙️ Best W-Engines for Sunna

1) Thoughtbop (Best-in-slot)

• Boosts off-field Energy Regen

• EX that deals Physical DMG grants a team damage buff that can stack up to 2

• At 2 stacks, it adds an extra ATK increase

• Only one instance of this squad effect can exist (clean, consistent “Support weapon” logic)

2) Weeping Cradle (Best generic alternative)

• Off-field Energy Regen trickle

• Adds escalating team damage taken-to-target amplification that ramps while active (strong for sustained pressure, especially on boss targets)

3) Kaboom the Cannon (Solid F2P-style team ATK ramp)

• Any squad hit can add stacks of team ATK (up to 4)

• Stack durations are separate, and multiple units can contribute
  Good when you want simple value and your team hits constantly.

💿 Best Drive Discs for Sunna

Best Set

Moonlight Lullaby (4-pc) + Astral Voice (2-pc)

• Moonlight Lullaby is your “Support identity” set — it pushes party-wide value

• Astral Voice (2-pc) feeds ATK, which Sunna’s Core scaling directly wants

Second Best

Moonlight Lullaby (4-pc) + Swing Jazz (2-pc)

• If you’re already hitting her ATK cap comfortably, Swing Jazz helps stabilize Energy Regen to keep EX timing smooth.

✅ Skill Priority (What to Level First and Why)

1. Core Skill — ★★★★★
   Your ATK buff scaling and Cat’s Gaze rules live here. This is Sunna.

2. Special Attack — ★★★★★
   This is how you turn the kit on (Angelic Chord-ination → Ether Veil → Quick Assist flow).

3. Chain Attack / Ultimate — ★★★★☆
   Improves the healing she provides and strengthens her “safety net” value.

4. Assist — ★★★☆☆
   Useful mainly for Defensive Assist Daze, but not your primary engine.

5. Basic Attack / Dodge — ★☆☆☆☆
   You’re not meant to camp her on-field — invest here last.

🎮 How to Play Sunna (The Real Rotation Logic)

Step 1: Apply Cat’s Gaze early

• Your first goal is simply: put Cat’s Gaze on the target

• Her EX Special options do it naturally while starting her buff state

Step 2: Maintain Claw Sharpeners so Cat’s Gaze never “falls off”

• She gains Claw Sharpeners when:

  • any squad member activates Ether Veil (she gains 2)

  • any squad member applies an Attribute Anomaly (she gains 1, max once per 10s)

• If she’s off-field and there are no enemies with Cat’s Gaze, Bubblegum can consume 1 Claw Sharpener to automatically attack and reapply pressure
  Translation: Sharpeners are your “autopilot fuel” that keeps Cat’s Gaze online without Sunna living on-field.

Step 3: Trigger Angelic Chord-ination → then Ether Veil: Delusion Reprise

• Use EX Special: Bubblegum Barrage to grant Angelic Chord-ination (40s)

• While in that state, use EX Special: Special Photography Technique to activate Ether Veil: Delusion Reprise
  This is the “stacked buff moment” you want right before your carry begins their real damage sequence.

Step 4: Cash out during Stun windows

• Cat’s Gaze triggers faster when the enemy is Stunned

• Pair Sunna with a reliable Stun unit if your carry loves burst windows, because Sunna turns Stun phases into “detonation phases.”

👥 Best Teams and Bangboo

✅ F2P Team (Simple and Functional)

• Sunna (Support) + Billy (Attack) + Anby (Stun)

• Bangboo: Sumoboo

• Alternatives: Bagboo / Brawlerboo / Overtimeboo
  Why it works: Billy takes buffs cleanly, Anby provides Daze to speed up Cat’s Gaze detonations.

✅ Attack Team Core (Universal “put Sunna behind a carry”)

• Sunna (Support) + Ye Shunguang (Attack) + Dialyn (Stun)

• Bangboo: Sprout

• Alternatives: Luckyboo / Bangvolver / Brawlerboo / Overtimeboo / Birkblick
  Notable note from your text: Ether Veil can help Ye Shunguang reach an Enhanced state faster, and Dialyn provides strong Stun value plus a “free Ultimate” style payoff in kit flow.

✅ Anomaly Team (Requires Aria)

• Sunna (Support) + Aria (Anomaly) + Yuzuha (Support)

• Bangboo: Biggest Fan

• Alternatives: Luckyboo / Bangvolver / Baddieboo / Bild N. Boolok
  Core reason: Aria can detonate Cat’s Gaze in an Anomaly context, which Sunna needs for Anomaly teams to feel complete.

🧩 Blueprint: Build Sunna Around the Two “Caps” and One Habit

The caps

• ATK cap 1: 1,750 initial ATK → Core buff maxed at early ceiling

• ATK cap 2: 3,500 initial ATK → true endgame scaling + smoother EX cadence

The habit

• Treat every fight like a loop:

  1. Mark (Cat’s Gaze)

  2. Stage (Ether Veil: Delusion Reprise)

  3. Detonate (during Stun / sustained pressure)
     If you can keep that rhythm, Sunna stops being “support maintenance” and becomes an always-on amplifier.
