Sampo | Honkai: Star Rail

Overview

Wind Nihility damage-over-time applier who stacks Wind Shear rapidly and increases the DoT damage enemies receive.

Role

Wind Shear applier and DoT amplifier.

Playstyle

Stack Wind Shear on priority targets, Ultimate before Kafka or allied DoT detonations, and Basic when stacks are maintained.

Why It Works

Repeated hits stack Wind Shear while Ultimate applies DoT vulnerability, making multi-hit Skill and effect reliability central.

Watch For

Random Skill bounces can dilute stacks in crowded waves, and low Effect Hit Rate makes both Wind Shear and vulnerability unreliable.

Playstyle

Combat Flow

Build Wind Shear on priority enemies with Skill. Apply Ultimate's DoT vulnerability before important DoT ticks or allied detonations. Basic when Wind Shear is established and the team needs Skill Points; at E4, Skill also gains value against targets with five Wind Shear stacks.

Key Notes

Talent can apply Wind Shear from Sampo's attacks, up to five stacks.
Trap extends Talent Wind Shear by one turn.
The Ultimate's DoT vulnerability benefits allied DoT as well as Sampo's.
Random bounces can spread hits away from a priority enemy.
E4 needs five Wind Shear stacks on the enemy being hit; it is not an unconditional extra hit.

Build & Investment

Light Cones

Primary

Eyes of the Prey

Adds Effect Hit Rate for application reliability and a damage bonus for Wind Shear.

Alternative

Good Night and Sleep Well

Raises damage for each debuff on the target, up to three; its effect includes DoT.

Situational

Resolution Shines As Pearls of Sweat

For a support role: hits can apply Ensnared to reduce enemy DEF when that debuff is not already present.

Relics

Primary

Prisoner in Deep Confinement

Adds ATK and ignores DEF according to the number of DoTs on the target, counting up to three. Five stacks of one Wind Shear are not five separate DoTs.

Planars

Primary

Revelry by the Sea

Adds ATK and grants DoT damage at 2400 and 3600 ATK. Evaluate the threshold with the actual team's buffs.

Alternative

Firmament Frontline: Glamoth

Adds ATK, then damage at 135 and 160 SPD. Do not sacrifice application reliability solely to chase the higher tier.

Eidolon Investment

E0 applies Wind Shear and DoT vulnerability. E4 adds Skill-triggered Wind Shear damage, and E6 strengthens the Talent DoT; build around the ranks already available.

Eyes of the Prey supplies useful Effect Hit Rate and DoT damage; Good Night and Sleep Well needs an adequate debuff count.

Adds one random Skill hit, creating another chance to apply Wind Shear.

Defeating an enemy with Wind Shear gives a 100% base chance to spread one Talent-equivalent Wind Shear stack to enemies.

Each Skill hit on an enemy with at least five Wind Shear stacks immediately deals 8% of the current Wind Shear damage.

Increases the Talent Wind Shear damage multiplier by 15 percentage points; this is not a generic damage bonus.

Teams

Recommended Teammates

Kafka
