Hey there, fellow Proxies! As we dive deeper into 2026's meta, I've been absolutely obsessed with dissecting the kit of Sunna, the S-Rank Physical Support Agent. Let me tell you, she's not just another healer or buffer; she's the conductor for a symphony of destruction, specifically tuned for our Attack and Anomaly specialists. Playing her feels like I've discovered a secret weapon that was hiding in plain sight, and today, I want to break down exactly why she's become a cornerstone of my most successful teams.

Her entire playstyle revolves around two core mechanics: Angel's Accord for allies and Cat's Gaze for enemies. Think of Angel's Accord not as a simple stat boost, but as a direct power siphon. She channels a portion of her own formidable Attack stat into her teammates, supercharging their damage output. It's like she's handing them a supercharged battery pack mid-fight. The real magic, however, lies with Cat's Gaze. This debuff is her signature mark, a predatory stare that lingers on foes whether Sunna is on the field or comfortably in the backline. Enemies branded with this mark become hyper-vulnerable, taking significantly increased damage. The effect intensifies based on who attacks them: an Attack Specialist tears into them with brute force, while an Anomaly Specialist triggers more complex, debilitating reactions. Setting this up is as crucial and satisfying as placing a masterfully crafted domino; once it falls, the chain reaction of damage is spectacular.

But her utility doesn't stop there. Sunna is also a maestro of the Ether Veil effect. She doesn't just activate it; she nurtures and extends its duration, allowing DPS characters who thrive under its influence to stay in their empowered state longer. It's the difference between a fleeting moment of power and a sustained onslaught.

🛠️ Gearing Up the Maestro: W-Engines & Drive Discs

As a primarily off-field support, Sunna's gear focuses on empowering her team indirectly. She's not the one swinging the sword, but she's the one sharpening it to a razor's edge.

W-Engine Philosophy:

We want engines that amplify team-wide damage and, crucially, feed Sunna two key resources: Energy Regen and Attack. A faster Ultimate rotation means more Angel's Accord uptime, and a higher Attack stat means a bigger buff for your carries. It's a virtuous cycle.

Drive Disc Sets:

The undisputed best-in-slot for her is the 4-piece Moonlight Lullaby set. This set is her lifeblood, providing the essential Energy Regen she craves while also boosting the team's damage—a perfect match for her kit. For the remaining two slots, slap on any 2-piece set that boosts her Attack, like Astral Voice. Here’s a quick breakdown:

📊 Stat Priorities: Hitting the Sweet Spot

Managing Sunna's stats is like tuning a high-performance engine. You're aiming for two key thresholds:

1. Energy Regen: Enough to maintain a smooth, consistent rotation for her Ultimate and skills.

2. Attack Stat: This is her most important offensive stat. We have a clear goal:

✨ The Magic Number: 3500 ATK ✨

Hitting 3500 Attack maximizes the potency of her Core Skill's buff. If you can reach this benchmark using only Attack main stats on two of your Drive Discs (typically slots #4 and #5), you have a fantastic optimization opportunity: you can switch the main stat on her #6 Disc to Energy Regen. This creates the perfect balance, ensuring her buffs are monstrous and she can keep them coming.

Stat Priority Checklist:

• Main Stats: Energy Regen (if needed for rotation) / ATK% > ATK%

• Sub-Stats: ATK% > Energy Regen > Flat ATK

⚡ Team Synergy: Building Around Sunna

Sunna shines brightest in teams built around Attack and Anomaly Specialty Agents. She's also the heart of any Angels of Delusion faction team, boosting her fellow idols to stardom. Let me share one of my favorite comps that has been clearing end-game content with ease:

Team: Ether Veil Powerhouse

• Main DPS: Ye Shunguang

  She's the star of the show, the cannon we're loading. Her massive damage potential is fully unlocked under Ether Veil, and with Sunna's buffs, her numbers go from impressive to screen-clearing.

• Stunner/Support: Dialyn

  The perfect setup artist. Dialyn rapidly fills the enemy Daze gauge for stuns, setting up Ye Shunguang for her maximum-damage Ultimate conversion. Her ability to gift Ye Shunguang a free Ultimate is the cherry on top, creating devastating damage windows. No Dialyn? No problem! Zhao is a great alternative for this slot.

• Support/Sustain: Sunna

  That's our girl! She amplifies the team's damage when Ether Veil is active (which is often, thanks to her), provides healing, and can even step in to deal respectable damage when Ye Shunguang needs a breather. She's the glue, the amplifier, and the safety net all in one.

Wrapping this up, mastering Sunna has completely changed how I approach team building. She’s more than a support; she’s a force multiplier, a strategic linchpin that turns strong teams into unstoppable ones. Getting her geared and understanding her rhythm is one of the most rewarding investments you can make in your roster right now. Trust me, once you experience the fluid, amplified destruction she enables, there's no going back!
