Mydei

Imaginary Destruction HP-scaling damage dealer with self-taunt

Released Mar 19, 2025

Mydei is an HP-scaling damage dealer whose Skill spends his current HP to build Talent Charge, while his Talent turns repeated HP loss into Vendetta, self-healing, extra actions, and automatic attacks. Consider him when you can support a character who deliberately spends HP and draws enemy attention, and whose damage scales from Max HP.

Mydei GUIDE

Understand Mydei

Useful when…

Using Skill and incoming attacks to build Charge, then letting Vendetta generate automatic attacks and a powerful charged attack.
Using Ultimate to restore HP, add Charge, hit a selected enemy and adjacent targets, and Taunt them.
Using his Technique to gather and daze nearby enemies before beginning combat.

HP loss, Charge, and Vendetta

Each 1% of Mydei's HP lost gives one Charge point, up to 200. His Skill consumes 50% of current HP and deals Imaginary damage based on Max HP; if there is not enough HP, it sets his current HP to 1. At 100 Charge, he consumes 100 points, restores 15% of Max HP, advances his action by 100%, and enters Vendetta. In that state, Max HP rises by 50% of current Max HP and DEF remains at 0. At the start of his turn he automatically uses Kingslayer Be King, which spends 35% of current HP and deals damage based on Max HP. Reaching 150 Charge during Vendetta grants an extra turn and automatically uses Godslayer Be God, consuming 150 Charge.

Ultimate, targeting, and survival

His Ultimate restores HP equal to 15% of Max HP, gives 20 Charge, deals damage to one enemy and adjacent targets, and Taunts them for 2 turns. The Taunt also makes the next Godslayer Be God prioritize that designated enemy; it applies only to the latest target. If a killing blow lands during Vendetta, Mydei is not knocked down: he clears Charge, leaves the state, and restores 50% of Max HP. This provides a recovery condition, but his DEF stays at zero during Vendetta, so the state carries a real incoming-damage risk.

Technique and trace investment

His Technique pulls nearby enemies in and dazes them for 10 seconds; actively attacking a dazed enemy to enter combat deals Imaginary damage to all enemies, Taunts them for one turn, and grants 50 Charge. For upgrades, Talent, Skill, and Ultimate govern the Charge cycle, automatic attacks, and recovery or control effects, while the Basic ATK is also Max-HP based but contributes less to the defining cycle. Consider HP and CRIT damage bonus traces as additional investment. His 50% current-HP Skill cost and automatic Vendetta actions make staying aware of current HP part of using him effectively.

Risk and control

Mydei's core loop deliberately spends HP: the Skill and automatic Kingslayer Be King can reduce him to 1 HP when current HP is insufficient. He can recover through the Talent's Vendetta entry and Ultimate, but the kit does not make the zero-DEF Vendetta state safe by itself. His Taunt directs attacks toward him, which helps build Charge through HP loss but also concentrates incoming pressure. Avoid treating his self-healing as a replacement for monitoring his survival.

Limitations and tradeoffs

Skill and automatic attacks consume current HP and can leave him at 1 HP when the available amount is insufficient.
Vendetta sets DEF to zero while increasing Max HP, and his Technique and Ultimate can Taunt enemies toward him.
His high Charge action requires accumulating HP loss; the automatic Godslayer attack consumes the 150 Charge reached during Vendetta.

Common mistakes to avoid

Using Skill at low current HP without accounting for it reducing Mydei to 1 HP.
Treating Vendetta as a defensive state despite its zero DEF.
Assuming the Ultimate's Taunt persists across targets; only the latest designated target applies.
