Overview
Mika's skill applies Soulwind stacks that buff Physical DMG and ATK SPD when teammates hit enemies. His burst provides healing and additional Soulwind application. Buffs scale with HP-build HP% and ER (180%+). He quickswaps in to apply buffs before Physical DPS on-field windows.
How to Play
Cast burst for healing, use skill (tap or hold for different targeting), then swap to Physical DPS. Mika stays off-field-Soulwind stacks apply on party member hits. Hold skill for more stacks on multiple enemies. At C6, Physical characters gain CRIT stats from his buff.
Optimal Rotation
Mika Burst → Mika Hold Skill → Fischl Skill → Raiden Burst → Eula Burst → Eula Skill → Eula NA combo. Apply Superconduct with Cryo/Electro before Eula's window. Refresh Mika buff when Soulwind expires.
F2P Options
Favonius Lance or Prototype Starglitter are F2P polearms. Noblesse 4pc is farmable. C0 Mika fully enables Eula Physical teams-C6 is luxury. Mika is a 4★ from Eula's banner.
Common Mistakes
Using Mika without Physical DPS-his buffs only benefit Physical damage dealers. Building ATK over HP%-buff scaling uses HP. Too little ER-burst healing and buff uptime suffer. Staying on-field-Mika is a quickswap support.
