Best Sampo Build Guide

Sampo Sub DPS Build - DoT DMG

Stat Targets

  • Effect Hit Rate 67%
  • ATK 2600 or higher
  • SPD 135+ / SPD must be higher than Kafka

This build lets Sampo deal damage while keeping his debuffs landing reliably through stacked Effect Hit Rate.
Prisoner in Deep Confinement heavily raises DoT damage and provides DEF ignore, which increases Sampo’s total damage.

Revelry by the Sea raises Sampo’s DoT DMG and directly increases his damage as long as he reaches 2400 or 3600 ATK.
