Playstyle overview

Mydei is a damage dealer who gains enhancements by consuming his own HP. Once Mydei has consumed a certain amount of HP, he enters the Vendetta state, gaining enhancements and automatically using powerful abilities. In this state, Mydei will not be knocked out even if he takes a fatal hit.

Pros & Cons

Pros

  • Outstanding damage
  • Completely immune to death and to crowd control
  • Has an enormous HP pool and scales off HP
  • Taunts enemies frequently and for a long time
  • Good Energy regeneration thanks to being hit constantly
  • His kit has absurdly high built-in offensive and defensive stat boosts
  • Flexible team building, and he can be played without a sustain unit
  • Still has room to grow stronger even though he is already very strong

Cons

  • The free Light Cones are fairly weak compared with his signature
  • He is forced into auto battle once he enters Vendetta, so the only thing you use by hand is his Ultimate
  • That forced auto battle makes certain enemy mechanics harder to handle

Best Mydei Build Guide

Main DPS Build

Stat Targets

  • HP 8000 or higher (out of combat)
  • CRIT Rate 90-100% (in combat)
  • CRIT DMG 150% or higher
  • SPD 134/135 or any higher SPD breakpoint

Mydei’s strongest build uses Scholar Lost in Erudition, because most of his damage comes from his Skill. The Bone Collection’s Serene Demesne Planar Ornament set is also a great fit, since Mydei has very high HP.

Mydei gets fixed CRIT Rate from the “Bloodsoaked Cloak” Trace, so you should prioritize a CRIT DMG piece to maximize his damage.

Mydei needs at least 8000 HP out of combat to receive the full bonus CRIT Rate from the “Bloodsoaked Cloak” Trace. You can use an HP Planar Sphere to reach that HP target easily.

For CRIT Rate, Mydei should be at 90% or higher, or close to 100% so his hits crit more consistently.
