Who is Sampo?

Sampo is a 4★ Wind DoT amplifier following the Nihility Path. He applies Wind Shear (stackable Wind DoT) via his Skill and AoE, and his Ultimate applies a teamwide DoT vulnerability debuff — increasing all DoT damage enemies receive. He is the premier budget Kafka DoT partner and remains useful even in later patches as an accessible DoT amplifier. Source: prydwen.gg.

Kit Summary

Skill

Deals Wind DMG to a single target, bouncing to adjacent enemies; applies Wind Shear (stackable Wind DoT, up to 5 stacks).

Ultimate

Deals Wind DMG to all enemies and applies DoT Vulnerability — all enemies take more DoT damage for 2 turns.

Talent

When Wind Shear is triggered, deals additional Wind DMG based on stacks.

Notable use case

Budget DoT amplifier for Kafka; the only 4★ that applies a teamwide DoT vulnerability debuff.

F2P Verdict

💎 F2P FriendlyPatch 4.2

The best free DoT amplifier and Kafka's most accessible 4★ partner. Always useful in a DoT composition and free from story rewards.

Given free via story content early in the game. Standard pool for Eidolons. E6 increases his Wind Shear stacks to 8 — a large damage increase. Very rewarding to farm Eidolons for if running a DoT team.

Frequently Asked Questions

Is Sampo good without Kafka?

His Wind Shear DoTs deal less damage without Kafka amplifying them, but his DoT vulnerability Ultimate still benefits any team running DoT characters like Guinaifen or Luka.

What Effect Hit Rate does Sampo need?

80%+ to reliably apply and stack Wind Shear. Below that threshold, stacks fall off and his DoT output drops sharply.
