Best Light Cones
#1
Lies Dance on the Breeze
Best option if Sampo reaches 170+ SPD. Increases SPD by 18% and applies a DEF reduction of up to 24% to all enemies. The "Theft" state stacks for additional DEF shred when that SPD threshold is met.
#2
Good Night and Sleep Well
Best widely accessible option. For every debuff the target has, Sampo deals up to 24% more DMG, stacking up to 3 times. This bonus also applies to DoT, making it perfect for Sampo's kit. Available from Stellar Warp.
#3
Eyes of the Prey
Increases Effect Hit Rate by 40% and boosts DoT damage by 48% at S5. Directly addresses Sampo's two key stats. Most commonly used by players in endgame (100% usage in AS data). Available from Stellar Warp.
#4
Resolution Shines As Pearls of Sweat
Applies Ensnare to enemies with a high base chance, reducing their DEF by 16% for 1 turn. Solid budget option that provides DEF shred to amplify all of Sampo's damage.
#5
Fermata
Increases Break Effect and boosts damage against enemies afflicted with Wind Shear or Shock. A decent stepping-stone option available from Stellar Warp if the above are unavailable.
Best Relics
Cavern Sets
1
Prisoner in Deep Confinement
Best-in-slot for Sampo. The 4-piece bonus ignores 6% of the target's DEF for each DoT afflicting them (up to 3 DoTs), for a maximum 18% DEF ignore. Since Sampo stacks Wind Shear, this translates directly to massive DoT damage increases. 100% of players use this in endgame modes.
2
Eagle of Twilight Line (2pc) + Prisoner (2pc)
Mixing the Eagle 2-piece (10% Wind DMG) with the Prisoner 2-piece (12% ATK) is a competitive alternative if you lack a well-rolled Prisoner 4-piece. After using Ultimate, Eagle also advances Sampo's action by 25%.
3
+
Flex 2-piece Mix
Combine any two 2-piece bonuses from: Pioneer Diver of Dead Waters, Musketeer of Wild Wheat, Prisoner in Deep Confinement, or The Wind-Soaring Valorous. Use whatever gives the best substat rolls until you farm your ideal Prisoner 4-piece.
Planar Ornament Sets
1
Revelry by the Sea
Best-in-slot planar set for Sampo. Increases ATK by 12%, and further boosts DoT DMG by 12% when ATK reaches 2400, or by 24% when ATK reaches 3600. With proper investment and team buffs, Sampo can hit both thresholds, directly supercharging his Wind Shear output.
2
Firmament Frontline: Glamoth (160 SPD)
Increases ATK by 12% and grants 18% more DMG when SPD reaches 160. If you can hit the 160 SPD breakpoint, this slightly edges out Revelry for pure damage output.
3
Firmament Frontline: Glamoth (135 SPD)
Same set at the easier 135 SPD threshold, granting 12% DMG bonus. A reliable choice if you are building toward a speed breakpoint and cannot yet hit 160 SPD.
4
Pan-Cosmic Commercial Enterprise
Increases Effect Hit Rate by 10% and converts 25% of current EHR into bonus ATK (up to 25% ATK). Useful if you need more Effect Hit Rate coverage while still boosting ATK.
Best Teams for Sampo
Sampo excels as a DoT Sub-DPS. His Ultimate amplifies DoT damage taken by all enemies, benefiting any teammate with DoT in their kit. Kafka is his premier partner, able to re-trigger active DoTs with her Skill and Ultimate.
01 · DoT Premium
Best-in-slot DoT composition
02 · Kafka + Gallagher
Accessible premium variant
Black Swan adds her own persistent DoT and amplifies all team DoTs further. Gallagher provides healing and applies his own debuff (Weaken), making this a strong triple-DoT team. Sampo's Ultimate DoT vulnerability debuff benefits all three DoT dealers simultaneously.

Rising Love
When using Skill, deals DMG for 1 extra bounce to a random enemy. This takes the Skill from 5 hits to 6 hits, adding more Wind Shear application chances, additional Toughness damage, and extra Energy gain. Considered one of the most valuable E1s for a 4-star character.
Highly Recommended

2
Infectious Enthusiasm
When an enemy with Wind Shear is defeated, there is a 100% base chance to inflict all remaining enemies with 1 stack of Wind Shear equivalent to the Talent's Wind Shear. Excellent for multi-wave fights and respawning enemies, keeping Sampo's DoT propagating automatically.

Big Money!
Skill Lv. +2 (max 15) and Basic ATK Lv. +1 (max 10). Increases Skill damage scaling directly, which improves both the direct hit damage and, more importantly, the frequency of Wind Shear application across multiple targets.
Skill Boost
E
4
The Deeper the Love, the Stronger the Hate
When Skill hits an enemy with 5 or more Wind Shear stacks, the enemy immediately takes 8% of the current Wind Shear DMG per hit. Since the Skill can hit 5-6 times, this effectively detonates 40-48% of the current Wind Shear damage on top of the DoT tick. A large burst damage spike at full stacks.
Burst Spike

Huuuuge Money!
Ultimate Lv. +2 (max 15) and Talent Lv. +2 (max 15). Both level increases improve core output: the Talent level boost raises Wind Shear's ATK multiplier from 52% to 57.2% per stack, and the Ultimate gets improved damage and DoT vulnerability scaling.
Core Upgrade

Increased Spending
Talent's Wind Shear DMG multiplier permanently increases by +15% per stack. Combined with E5, Wind Shear goes from 52% to 72.2% ATK per stack, for a total of 361% ATK per turn at 5 stacks. Simulation shows E6 Sampo dealing 170.92% more damage than E0 in single target, and 157.58% more in 3-target scenarios.
Massive Upgrade

Trap
Ascension 2
Extends the duration of Wind Shear caused by Sampo's Talent by 1 additional turn, bringing the total duration to 4 turns. With 4-turn Wind Shear, even the fastest enemies in the game cannot avoid it; no enemy in the current meta moves fast enough to outlast 4 of Sampo's turns.
Defensive Position
Ascension 4
Using Ultimate additionally regenerates 10 Energy. This effectively reduces Sampo's Ultimate cost from 120 to 110 Energy, letting him loop his Ultimate more frequently and maintain higher uptime on the DoT vulnerability debuff.
Spice Up
Ascension 6
Enemies affected by Wind Shear deal 15% less DMG to Sampo. Since Sampo will nearly always have Wind Shear on enemies at all times in combat, this is effectively a permanent 15% damage reduction, significantly improving his survivability without any additional defensive investment.

Frequently Asked Questions
Sampo is a solid B-Tier 4-star who performs reliably in a Kafka DoT team. While he has fallen behind newer limited 5-star damage dealers, he remains a consistent performer who can be SP-positive, deals excellent Toughness damage against Wind-weak foes, and provides a team-wide DoT vulnerability debuff via his Ultimate. For players who enjoy the DoT archetype or need a Wind character, he is worth building.
No, but Kafka is his best synergy. Kafka can re-trigger Sampo's Wind Shear DoTs with her Skill and Ultimate, dramatically amplifying his passive damage. Without Kafka, Sampo still deals consistent Wind Shear damage on his own and can be paired with other DoT characters like Serval, Himeko, or Luka. His Ultimate's DoT vulnerability debuff benefits any DoT ally, not just Kafka.
The recommended breakpoints are 134 SPD, 143 SPD, or 160 SPD. Many players run 134 SPD as a comfortable midpoint. If you can equip Lies Dance on the Breeze, pushing toward 160 SPD is highly rewarding since that threshold unlocks the additional DEF shred. Sampo should generally move faster than enemies to maximize Wind Shear uptime and Ultimate frequency.
Each of Sampo's attacks has a 65% base chance to apply Wind Shear for 3 turns (4 turns with the A2 trace). Wind Shear stacks up to 5 times, with each stack dealing 52% of Sampo's ATK as Wind DoT at the start of the enemy's turn. You only need to reapply once to refresh the entire stack duration, meaning you have generous windows to maintain 5 stacks. At max stacks, enemies tick 260% ATK in Wind DoT each turn passively.
E1 is highly recommended: adding a 6th Skill bounce gives more Wind Shear applications, more Toughness damage, and more Energy per rotation. E4 is the next major spike, allowing Sampo to detonate 40-48% of current Wind Shear damage when hitting an enemy at 5 stacks. E6 is a significant but costly upgrade, boosting the Wind Shear multiplier by 15% and resulting in 170% more single-target damage vs E0 in simulations.
Yes. Sampo's Ultimate increases DoT taken by affected enemies by 30% for 2 turns, and this applies to all DoT sources, including Kafka's Shock, Black Swan's Arcana, Luka's Bleed, Himeko's Burn, and even Break-inflicted DoTs. This makes Sampo a genuine team DoT amplifier, not just a selfish damage dealer, and is the main reason he pairs so well with multi-DoT compositions.
