Sampo Gameplay
Sampo is a 4-star Wind Nihility character who specializes in persistent multi-target pressure through his signature Wind Shear application. His Skill, Ricochet Love, throws a dagger that bounces between enemies, dealing Wind damage multiple times. This "bounce" mechanic is remarkably effective for both shredding the Toughness bars of Wind-weak bosses and ensuring that debuffs are spread across the entire enemy field in a single turn.
His combat utility revolves around the synergy between his Talent and his Wind Shear stacks. Whenever Sampo attacks—whether through his Basic ATK, Skill, or Ultimate—he has a high base chance to inflict Wind Shear, which can stack up to 5 times. His Ultimate, Surprise Present, transitions his role into a premier DoT enabler, dealing AoE damage while significantly increasing the DoT taken by all enemies. This makes him a vital anchor for teams featuring Kafka or Black Swan, as he effectively amplifies the team's total damage floor.
Sampo's passive Traces are what truly solidify his position as a sustainable DoT carry. His A2 Trace (Trap) is a game-changer, extending his Wind Shear duration to 4 turns, which drastically improves his skill-point efficiency in long battles. His A4 Trace (Defensive Position) restores 10 Energy upon using his Ultimate, allowing for faster rotation cycles and higher debuff uptime. Finally, his A6 Trace (Spice Up) grants him a 15% damage reduction from enemies afflicted with Wind Shear, providing the necessary survivability to stay in the spotlight during high-level endgame content.
Sampo Trace Priority
| Trace | Priority |
| Talent | ★★★★★ (Top) |
| Ultimate | ★★★★☆ (High) |
| Skill | ★★★☆☆ (Mid) |
| Basic | ★☆☆☆☆ (Low) |
Sampo’s Talent is his most vital trace because it defines his role as a premier DoT dealer. It governs the damage multiplier of his Wind Shear, which is the primary source of his DPS. Since Sampo can stack up to five layers of Wind Shear on a single target, every level invested here exponentially increases the "ticking" damage enemies take at the start of their turns. In the 2026 meta, where bosses have massive HP pools, maximizing this scaling is non-negotiable for any Nihility-focused team.
His Ultimate is a high priority due to its unique team-wide utility. While the direct Wind damage is modest, its true value lies in the DoT Vulnerability debuff it applies to all enemies. Investing in this trace increases the percentage of extra damage enemies take from all DoT sources (Bleed, Shock, Burn, and Wind Shear). This makes Sampo an indispensable partner for characters like Kafka or Hysilens, as he effectively acts as a global damage multiplier for the entire squad's elemental effects.
Sampo’s Skill is a mid-level priority. It serves as his primary tool for Weakness Breaking and rapidly stacking Wind Shear thanks to its "bounce" mechanic. While leveling this trace increases the direct damage of the daggers, the bulk of his performance comes from the DoT applied by his Talent rather than the hits themselves. However, keeping this trace leveled is still beneficial for clearing smaller "trash" mobs and ensuring he contributes meaningful chip damage during his rotation.
His Basic ATK is the lowest priority. In optimal rotations, Sampo only uses his Basic ATK to generate Skill Points (SP) when his stacks are already capped or when SP is scarce. The damage scaling is negligible, so your resources are better spent elsewhere. Prioritize unlocking his Bonus Traces instead, particularly Trap, which extends his Wind Shear duration to 4 turns, significantly reinforcing his efficiency in high-level content like the Simulated Universe: Gold and Gears.
Sampo Best Light Cones
To select the ideal Light Cone for Sampo, evaluate your build against these three tactical needs to ensure his daggers—and his jokes—hit exactly where they hurt the most:
Maximizing Total Damage Ceiling: Since Sampo thrives on stacking debuffs to amplify his Wind Shear, prioritize Light Cones like Lies Dance on the Breeze or Good Night and Sleep Well. These provide massive damage multipliers that capitalize on the sheer number of status effects on the enemy. Lies Dance on the Breeze is the premier choice for the 2026 meta, offering not just a significant damage boost but also unique debuff layers that allow Sampo to act as a pseudo-Harmony unit for his fellow DoT teammates.
Ensuring Wind Shear Consistency: Sampo’s entire kit falls apart if he can’t land his stacks. To maintain high Effect Hit Rate (EHR) without sacrificing your relic substats, Eyes of the Prey remains his most reliable companion. It provides a massive 40% EHR boost at S5, which is essential for bypassing the high Effect RES of endgame bosses, effectively guaranteeing that every bounce of his skill results in a fresh stack of Wind Shear.
Bolstering Team-Wide Utility: If you're running Sampo as a sub-DPS or support enabler for a powerhouse like Kafka, Resolution Shines As Pearls of Sweat is a tactical masterstroke. By applying the "Ensnared" state, Sampo can shred enemy DEF, allowing the entire team’s damage to bypass enemy armor. This utility is vital in high-level content where enemy defenses are the biggest hurdle to a fast clear.

Sampo Relics, Ornaments & Stats Priority
The 4-piece Prisoner in Deep Confinement set stands as the absolute best choice for Sampo in the current meta, as it successfully bridges the gap between a utility debuffer and a dedicated DoT carry. The 2-piece and 4-piece bonuses significantly amplify his Wind Shear effectiveness, but the true value lies in the unique passive that grants up to an 18% DEF ignore against targets afflicted with multiple status effects. If you are looking for a more tactical, "turn-cycling" build, the 4-piece Eagle of Twilight Line remains a powerful second-best option, focusing entirely on maximizing Action Advance to ensure he can stack Wind Shear faster than the enemy can recover. Finally, for a more accessible and high-speed build, a 2-piece hybrid of Prisoner in Deep Confinement and Messenger Traversing Hackerspace is a reliable third choice, offering a balanced mix of raw ATK and a permanent 6% SPD boost to keep his skill cycling efficiently.

Sampo Best Teams
To choose the best team for Sampo, look for synergistic Damage over Time (DoT) compositions where his multi-hit daggers can rapidly apply Wind Shear stacks while amplifying the team's total damage floor. Because his Ultimate provides a unique DoT Vulnerability debuff, he is a game-changer for allies like Kafka or Black Swan who rely on high-frequency elemental ticks to dismantle boss health bars. His kit acts as a reliable toughness-breaking engine, making him a perfect fit for Nihility-focused strategies that benefit from frequent, automatic strikes. Additionally, his ability to transition into a "detonator" at E4 and pair with modern 2026 supports like Hysilens or DHPT makes him a comfortable, utility-minded pick for any lineup that requires a blend of focused single-target pressure and wide-scale battlefield control.

Sampo Eidolons
While Sampo is functional as a DoT enabler at E0, his Eidolons are some of the most impactful in the game for a 4-star character. They transform him from a simple "Wind Shear bot" into a potent sub-DPS that can actively trigger his own damage.
Eidolon Performance
| Eidolon | Rating | Explanation |
| E1 | ★★★★☆ | Rising Love. Adds 1 extra bounce to his Skill (moving from 5 hits to 6). This is huge for Energy generation and for hitting that 5-stack Wind Shear cap on bosses much faster. |
| E2 | ★★★☆☆ | Infectious Enthusiasm. When an enemy is defeated while under Wind Shear, all other enemies gain 1 stack. Excellent for "trash" mobs, but has zero value in solo-boss fights. |
| E4 | ★★★★★ | The Deeper the Love, the Stronger the Hate. This is his "Kafka moment." If an enemy has 5+ stacks, his Skill daggers instantly trigger 8% of that total DoT damage. This is why Sampo is viable as a main DPS. |
| E6 | ★★★★★ | Increased Spending. Flatly increases his Wind Shear damage multiplier by 15%. This sounds small, but because it applies to every single stack, it boosts his total damage floor by a massive margin. |
Eidolon Effect
| Eidolon | Effect |
E1 | ''Rising Love'' When using Skill, deals DMG for 1 extra time to a random enemy. |
E2 | ''Infectious Enthusiasm'' Defeating an enemy with Wind Shear has a 100% base chance to inflict all enemies with 1 stack(s) of Wind Shear, equivalent to the Talent's Wind Shear. |
E3 | ''Big Money!'' Skill Lv. +2, up to a maximum of Lv. 15. Basic ATK Lv. +1, up to a maximum of Lv. 10. |
E4 | ''The Deeper the Love, the Stronger the Hate'' When Skill hits an enemy with 5 or more stacks of Wind Shear, the enemy immediately takes 8% of the current Wind Shear DMG. |
E5 | ''Huuuuge Damage!'' Ultimate Lv. +2, up to a maximum of Lv. 15. Talent Lv. +2, up to a maximum of Lv. 15. |
E6 | ''Increased Spending'' Talent's Wind Shear DMG multiplier increases by 15%. |
Conclusion
Sampo is far more than just a silver-tongued merchant; he is a relentless Damage over Time (DoT) specialist that truly finds his stride in Wind Shear stacking and high-frequency detonation compositions. His kit is built around his multi-hit skill and his ultimate's vulnerability debuff, which essentially allow him to amplify team-wide damage while acting as a reliable energy battery for himself. By focusing on his ATK, Speed, and Effect Hit Rate stats, you ensure his daggers remain a constant threat while keeping his Ultimate ready to melt enemy health bars exactly when the team needs to break through.
In the heat of endgame content, Sampo stands out because he provides a unique blend of sustained pressure and damage amplification that traditional DPS characters cannot match, amping up the squad's overall output by providing essential debuffs and specialized synergy for other DoT units.
