This guide covers the Light Cones, Relics, Trace priority, stat priority, teams, and Eidolon verdicts for the best Mydei build in this guide, along with a full rotation breakdown and my final verdict on whether he’s worth investing into right now.
Mydei is a 5-star Imaginary Destruction unit who turns his own HP into damage, consuming a chunk of his current health every time he uses his Skill and getting stronger for it. He is built to tank hits, taunt the field, and keep swinging without a sustain unit propping him up if you build him right.

How to play Mydei: Rotation and Tips
Mydei’s playstyle revolves around a single resource:
his own HP. Every Skill, Deaths are Legion, Regrets are None, burns 50% of his current HP to hit one enemy hard and splash the rest, and every point of HP he loses feeds his Talent’s Charge meter.
Once that meter fills, he enters the Vendetta state, where his Max HP balloons and his DEF drops to zero, and his kit shifts to auto-firing his strongest attacks.
Once Vendetta is active, Kingslayer Be King and eventually Godslayer Be God trigger automatically at the start of his turn, so there’s very little manual sequencing left to manage.
Just remember to keep his HP topped up enough that he can keep affording his own Skill, and building enough Max HP that his passive CRIT Rate and healing bonuses from Bloodied Chiton stay maxed out.
