Mydei is an Imaginary Destruction damage dealer who scales entirely on Max HP. Every 1% of HP he loses becomes Charge: at 100 Charge he enters Vendetta, where he gains 50% Max HP, acts automatically and becomes immune to crowd control, and at 150 Charge he unleashes Godslayer Be God, his strongest Blast attack. He is SP-friendly, extremely hard to kill and can even be played without a dedicated sustain.

HP DPS

Light Cones

Flame of Blood, Blaze My Path BiS
5★
Signature and best in slot by a landslide: huge base HP, Max HP, a 60% DMG bonus on most of his kit, and extra HP consumption that builds Charge faster.
Max HP +18% and Incoming Healing +20%; the Skill and Ultimate consume 6% of Max HP for +30% DMG, or +60% if over 500 HP is consumed.
The Unreachable Side
5★
Blade's signature: good stats all round, though its CRIT Rate overlaps with Bloodied Chiton.
CRIT Rate +18% and Max HP +18%; being attacked or consuming HP grants +24% DMG until the next attack.
Ninja Record: Sound Hunt
4★
Game8's best 4★ pick (from an event): HP% and a CRIT DMG buff he keeps active 100% of the time.
Max HP +12%, and losing or restoring HP grants +18% CRIT DMG for 2 turns (once per turn).
A Secret Vow
4★
Prydwen's best 4★ pick at S5, slightly ahead of Ninja Record: he spends much of the fight below max HP, so the extra DMG bonus is often active.
DMG +20%, plus another 20% against enemies whose HP percentage is at or above the wearer's.
Flames Afar
4★
Free fallback: less HP and a buff that isn't always up.
Losing or consuming over 25% of Max HP at once heals 15% of Max HP and grants +25% DMG for 2 turns (once every 3 turns).

Teams

Recommended teams

Cyrene hypercarry

Mydei
Cyrene
Robin • Summeretto
Hyacine

Game8's recommended team: Cyrene's Ultimate triggers Godslayer Be God on demand and boosts its CRIT DMG, Robin • Summeretto adds offensive buffs, and Hyacine (a Chrysos Heir) keeps Cyrene's Ultimate coming while raising his Max HP.

Chrysos Heirs

Mydei
Cyrene
Trailblazer (Remembrance)
Hyacine

His most used team on Prydwen: the Trailblazer (Remembrance) adds CRIT DMG, True DMG and occasional action advances, and helps charge Cyrene's Ultimate.

Budget

Mydei
Trailblazer (Remembrance)
Pela
Lynx

Free-to-play option: Pela lowers DEF, and Lynx raises his Max HP and his chance of being attacked while healing him.

Guide

How to play

How he works

  • Charge (Talent). Mydei gains 1 Charge per 1% of HP lost (up to 200). At 100 Charge, he consumes it to enter Vendetta: he restores 25% of his Max HP, advances his action by 100%, gains Max HP equal to 50% of his current Max HP, but his DEF drops to 0.
  • Vendetta. At the start of each turn he automatically uses Kingslayer Be King (consumes 35% of his current HP, Blast). When Charge reaches 150, he immediately takes an extra turn to use Godslayer Be God (280% of his Max HP on the main target). A killing blow normally ends Vendetta, clears his Charge and heals him for 50%; his A2 (Earth and Water) keeps him in Vendetta instead, up to 3 times per battle. His A4 (Thirty Tyrants) makes him immune to crowd control in Vendetta.
  • Bloodied Chiton (A6). At the start of battle, each 100 Max HP above 4,000 gives him 1.2% CRIT Rate, 2.5% more Charge from enemy damage and 0.75% more healing received — capped at 8,000 HP (48% CRIT Rate, +100% Charge, +30% healing received).
  • Ultimate (160 Energy). Heals 20% of his Max HP, grants 20 Charge, deals Blast DMG and Taunts the target and adjacent enemies for 2 turns. The next Godslayer Be God targets the Ultimate's main target.

Rotation

  1. Use his Technique: an AoE opener that Taunts enemies and grants 50 Charge.
  2. Outside Vendetta, use his Skill (consumes 50% of current HP) to reach 100 Charge quickly.
  3. In Vendetta, he plays by himself: your only input is his Ultimate. Use it to top up Charge and pick Godslayer Be God's target — with 4-piece Scholar Lost in Erudition, cast it right before Godslayer so the set bonus applies.

Tips

  • 8,000 HP before combat is his key target: it maxes Bloodied Chiton.
  • A strong healer means more HP to lose, hence more Charge. Cyrene can trigger Godslayer Be God on demand with her Ultimate.
  • Forced auto-battle in Vendetta can make some enemy mechanics trickier to handle.

Strengths

  • Excellent damage output
  • Immune to death and crowd control in Vendetta
  • Massive HP and self-sustain
  • Frequent, long-lasting enemy Taunts
  • Great Energy economy from constantly getting hit
  • Flexible team building, can even skip the sustain slot

Weaknesses

  • Free Light Cones are far behind his signature
  • Forced auto-battle in Vendetta: you only control his Ultimate
  • Auto-battle can make some enemy mechanics harder to deal with
