Overview
Suomi's Mod fixes almost all the issues with her pre-Mod version, and then goes on to make her practically the strongest tank in the game.
Her abysmal Evasion is fixed immediately upon rarity change. She gets an extra tile behind her and the multipliers are significantly improved. She gains a massive 150 HP shield with permanent duration upon Skill 1 activation with a massive 35% Damage Reduction rivaling Alchemist in her tanking abilities.
Skill 2 in itself is very wordy but quite simple in practice. Suomi now shoots randomly, changing her target constantly. This is actually a good thing, because all her shots now apply a stack of Chill regardless if it hits. Every 4 seconds, every Chill stack will be consumed which will damage the enemy and give them various debuffs. The damage is a flat 10% of their current HP, capped at 100000 HP (don’t worry much about this cap, only some of the newer bosses will actually be able to reach it). Most importantly though, each Chill stack consumed gives a 4 HP shield, an additional 0.5% damage (this brings 1 stack damage to 10.5%) and debuffs to EVA, RoF and MOV for 10% each, stacking up to 3 times. The extra shields from Skill 2 work alongside the bigger shield from Skill 1, and even activates the damage reduction if Skill 1’s shield is depleted.
With all of the above, it’s easy to see why Suomi has ascended to the top of the SMG hierarchy. She requires so little effort from your part, giving you so much in return. There’s no fancy bells or whistles to how she works, she keeps up all her own shields and protects everyone else while doing so. MOD2 is where she reaches the apex of her survivability, but even MOD1 is a strong upgrade if you’re currently low on resources.
