Girls Frontline 2 Suomi Build: Why She Is Basically Mandatory

You've probably seen the tier lists. You’ve seen people screaming about "V1 or bust." Honestly, if you’re playing Girls' Frontline 2: Exilium, Suomi isn't just another unit you pull because she looks cool—though the Konepistooli drip is real. She is the backbone of almost every high-level team right now.

If you don't have a solid Girls Frontline 2 Suomi build, you're basically playing the game on "Hard Mode" without even knowing it. She heals. She shields. She cleanses those annoying stuns. She even does weirdly high damage for a support.

Let's break down how to actually build her so your team doesn't melt the second a boss looks at them.

The V1 Power Spike: Why Everyone Wants a Duplicate

Look, a "base" Suomi (V0) is good. She gives you shields based on her attack stat. But the real magic happens at Vertebrae 1 (V1).

Once you get that first duplicate, her Ultimate changes. It doesn't just shield anymore; it starts healing for a massive chunk of her max HP. In GFL2, losing HP usually means your Stability is gone, and you’re about to die. Suomi V1 fixes that. She also starts cleansing harder CC like Stun and Fear.

If you're F2P, saving your Collapse Pieces for her rerun to hit V1 is probably the smartest move you can make.

Best Weapons for Suomi

You have two real choices here. One is the "I spent money" option, and the other is the "I'm smart with resources" option.

• Unspoken Calling (Signature SSR): This is her "BiS" (Best in Slot). It’s designed specifically to make her shields beefier and her healing more consistent. If you have it, use it. Don't look back.
• Suomi (SR SMG): Yeah, the weapon is literally named after her. It's surprisingly great because it boosts shield effects by 5% and has solid attack scaling. For a free-to-play player, this is more than enough to clear 99% of the content.

Don't sweat the purple weapons too much. Just make sure whatever you equip has a high Attack stat, because her Frost Barrier shield scales directly off it. No attack, no shield. Simple as that.

The Attachment Meta: Ultimate Pursuit vs. Emergency Repair

This is where most people get confused. What set should you actually farm?

1. Ultimate Pursuit (The Scaling Choice)

This is the go-to for most builds. It increases the healing and shield strength of her Ultimate by 5%. Every time you use the Ult, it stacks, up to 20%. In long boss fights, this makes your team virtually unkillable.

2. Emergency Repair (The V1 Stability Choice)

If you have Suomi at V1, Emergency Repair becomes a monster. Since she now heals with her active skills, this set allows her to restore 2 Stability points to allies she heals to full.

Pro Tip: If you're struggling with "Stability Break" (where your dolls lose their cover bonus), switch to Emergency Repair. It keeps your dolls tucked safely behind their cover for much longer.

Substat Priority

When you're calibrating your gear, don't just click "Accept" on everything. You want these stats in order:

1. Attack / Attack % (Crucial for shield health)
2. Health / Health % (Crucial for her V1 healing)
3. Defense (Helps her survive when she's flanking)

Neural Helix: What to Click First

Don't just randomly dump your Cores. Focus on these specific nodes to get the most out of her kit:

• Little Guardian: This gives you three starting skill points. This is huge. It means you can pop your defensive skills or Ultimate much earlier in the fight.
• Winter's Ref: This helps restore Stability when you hit a Stability Break on an enemy. It’s great for momentum.
• Immovable: This node lets Suomi cleanse herself of Stun or Taunt immediately. A support who can't move is a dead support.

Team Synergies: Who Plays Well with Suomi?

Suomi is a "Freeze" element unit, but she’s flexible enough to fit anywhere. That said, she has a "best friend" in the current meta.

The Macchiato Pair
Macchiato is the premier single-target DPS, and she loves Freeze. Suomi can implant Freeze weaknesses into enemies, which lets Macchiato basically delete them from the map.

The Ice Team (Suomi + Lotta)
Lotta provides the AOE, Suomi provides the sustain. It’s a classic combo. If you’re running this, you can basically ignore most mechanics because the enemies will be too frozen to do anything about it.

The "Standard" Hypercarry
If you're running someone like Qiongjiu, Suomi is just there to make sure Qiongjiu never has to stop shooting. Her shields allow your DPS to stay in aggressive positions without worrying about chip damage.

Actionable Steps for Your Suomi Build

Stop overthinking it and just do this:

1. Check your V-level. If you’re V0, focus on Attack stats and Ultimate Pursuit. If you’re V1, start looking for Emergency Repair to fix your Stability issues.
2. Level her Signature or the SR "Suomi" weapon to max. Do not neglect the weapon level; the base Attack stat is the most important part of her kit.
3. Unlock "Little Guardian" in the Neural Helix. Being able to shield on turn one changes how you play the opening of every map.
4. Farm the "Targeted Study" for gold attachments. You want that Ultimate Pursuit set effect as soon as possible.

Suomi makes the game feel different. Without her, you're constantly worrying about HP bars. With her, you're just worrying about how fast you can clear the stage. Build her right, and she’ll carry you through the 2026 meta and beyond.

Check your inventory for those Intelligence Puzzles and get farming—those Attack % substats aren't going to roll themselves. Once you've hit at least 100% Attack scaling on her shields, you'll see exactly why she's considered the best unit in the game.
