Who is Suomi?

Suomi is an Elite Doll (SSR) and a member of the Support class. She was the first targeted banner character and is known for meta-defining Ultimate, which sponges incoming damage and heals all allied units on the battlefield.

Her ability to apply AoE Freeze and targeted Freeze damage to her enemies also makes her punch above the standard Support role. Her official description describes her as “calm and resolute” and a Doll that has a strong sense of duty.

Best weapon

Sunborn

The best Suomi weapon is the Unspoken Calling. This SMG is Suomi’s signature weapon and increases the value of her shield, increasing it by a maximum of 20%. If that wasn’t exciting enough, Unspoken Calling also raises all allied Freeze damage by 20%. Essentially, you’ll be able to unleash tankier shields and deal more damage to your enemies if you’re using a Freeze team comp.

Next up is the Classified Manuscript. This SMG applies additional movement during the next action and ignores enemy defense based on every tile Suomi moves. You’ll also be able to cleanse a random buff if your movement exceeds five tiles.

Of course, if you’re not lucky enough to roll one of these SSR weapons, then there are some other great SR options that we’ve listed in the table below:

Weapon	Trait	Effect
Unspoken Calling (Signature)	If the character moves 5 tiles or more, they gain Movement Boost II at the start of their next action, lasting for 1 turn.	Freeze damage dealt by all allied units is increased by 10/12/14/16/18/20%. The value of applied Shield is increased by 10/12/14/16/18/20%. If the user’s Stability index is greater than 0 before using the Ultimate skill, the value of the applied Shield increased by another 10/12/14/16/18/20%.
Classified Manuscript (SSR)	If this unit has moved 5 tiles or more, gains Movement Up II for 1 turn at the start of the next action.	For every 1 tile moved, ignores 5/6/7/8/9/10% of the target’s defense, up to a maximum of 25/30/35/40/45/50%. If movement exceed 5/5/4/4/4/3 tiles, cleanses 1/1/2/2/2/3 random buff from the target before attacking.
Suomi (SR)	If the character moves 5 tiles or more, they gain Movement Boost II at the start of their next action, lasting for 1 turn.	Shield application effects are increased by 5/6/7/8/9/10%. When granting buffs to allied units (excluding self), healing effects are increased by 5/6/7/8/9/10 % for 2 turns.
MP7H1 (SR)	If this unit has moved 5 tiles or more, gains Movement Up II for 1 turn at the start of the next action.	When applying a buff to an allied target, increases damage dealt by the next active skill by 10/12/14/16/18/20%.

Best team comp

Sunborn

While Suomi can be slotted into any team comp, we recommend using the following characters to get the best results from her on the battlefield.

• Makiatto (DPS)
• Qiongjiu (DPS)
• Tololo (DPS)/ Sharkry (DPS)
• Suomi (Healer)

This team has amazing damage output thanks to three DPS units of Makiatto, Qiongjiu, and Tololo or Sharkry. Makiatto’s self-targeted shield is bolstered even further with Suomi’s Ultimate, making it near impossible for enemy units to damage Makiatto.

Additionally, Suomi’s Ult also applies Frost tiles onto the battlefield which apply Freeze weakness to enemies that step into it. This makes Makiatto’s Freeze attacks even more lethal. We recommend rounding off the team with Qiongjiu for her amazing support attack synergy and Tololo/Sharkry for even more DPS.

Best Suomi build

The best Suomi build uses Unyielding Momentum, Little Guardian, and Positive Feedback Fixed Keys. The set you want to farm for is the Ultimate Pursuit set, as this increases the damage of healing and shield effects of Ultimate skills by 5%. Suomi will also gain one stack after each use of her ult up to a maximum of four stacks.

The second attachment set we recommend farming is Phase Strike. Phase Strike deals 15% increased damage to targets with Phase Element debuffs, which makes it a great fit for Suomi and other Dolls in the game. If you want a universal attachment build and don’t want to spend hours farming Ultimate Pursuit, then definitely farm Phase Strike instead.
