Sampo GUIDE

Understand Sampo

Useful when…

Inflicting and stacking Wind Shear with attacks.
Increasing enemies’ DoT taken with his Ultimate.
Using his Technique to blind nearby enemies before combat.

Wind Shear and attacks

Sampo’s Skill hits a chosen enemy and makes four additional hits, each against a random enemy. His Talent gives attacks a 65% base chance to inflict Wind Shear for three turns. Wind Shear deals Wind DoT at the start of an enemy turn and can stack up to five times. His Ultimate damages all enemies and has a 100% base chance to increase their DoT taken by 20% for two turns. His Technique blinds nearby enemies for ten seconds. If combat starts against a Blinded enemy, the listed fixed chance to delay all enemies’ actions by 25% is 100%.

Practical use and investment

His Skill’s random follow-up hits can distribute damage among enemies, while his Ultimate’s DoT-taken increase can benefit DoT effects during its two-turn duration. His damage and Wind Shear scale from ATK. Skill, Ultimate, and Talent upgrades support the bounce damage, DoT-taken increase, and Wind Shear respectively. Bonus traces include Effect Hit Rate and ATK; these are separate unlocks with listed prerequisites and costs.

Limits and comparison

The four additional Skill hits target random enemies, so their distribution is not controlled. Wind Shear uses a base chance, and the Technique’s action delay applies when combat begins against a Blinded enemy.

Limitations and tradeoffs

Skill hits after the first target random enemies.
Wind Shear application uses a base chance, and DoT damage occurs at the start of enemy turns.

Common mistakes to avoid

Expecting all Skill hits to target the chosen enemy.
Treating the Wind Shear base chance as a guarantee.
Treating the Ultimate’s DoT-taken increase as a general damage increase.
