Summary
Mydei is a 5-star Imaginary Destruction DPS who scales heavily with HP. This HSR Mydei build guide covers his best Light Cones, relics, trace priorities, and team setups to unleash his full power.
Best Honkai Star Rail Mydei Build: Light Cones, Relics, Teams, and More
Mydei thrives on stacking HP—ideally over 8,000—to unlock massive CRIT Rate bonuses and faster talent charges. His unique Vendetta state triggers when fully charged, where he autonomously uses powerful enhanced skills. This makes Mydei easy to play but extremely strong, especially in hypercarry teams.
Best Light Cones for Mydei
- Flame of Blood, Blaze My Path: Signature Light Cone boosting Max HP and Incoming Healing. Consumes HP on Skill/Ultimate to increase damage up to 80% more if the consumed HP exceeds 500. Perfect for sustaining and maximising his HP-based damage.
- The Unreachable Side: Raises CRIT Rate and Max HP, and boosts damage when Mydei consumes HP or is attacked. Offers near-constant damage increase for sustained fights.
- A Secret Vow: Provides a flat damage boost plus extra damage when Mydei’s HP percentage is higher than enemies. Great for maintaining high damage output.
- Ninja Record: Sound Hunt: Boosts Max HP and CRIT DMG when losing or restoring HP, which synergises well with Mydei’s self-damaging playstyle.
- Flames Afar: Heals and boosts damage after losing over 25% HP in a single attack, ideal for burst phases.

- Scholar Lost in Erudition (4-piece): +8% CRIT Rate; increases Skill and Ultimate damage by 20%, plus 25% more Skill damage after Ultimate.
- Longevous Disciple (4-piece): +12% Max HP; grants stacks of CRIT Rate when hit or consuming HP.

Trace and Skill Priority for Mydei
Prioritize upgrading Mydei’s Skill first, then Ultimate, followed by Talent and lastly Basic Attack, as his enhanced state rarely uses Basic Attacks.
For Traces, focus on:
- Major Trace 1 (Earth and Water): Survival boost during Vendetta.
- Major Trace 2 (Thirty Tyrants): Immunity to Crowd Control.
- Major Trace 3 (Bloodied Chiton): CRIT Rate scaling with excess HP, key for maximizing damage.
Team Composition for Best Mydei Build
Mydei excels in hypercarry teams with supports who boost HP scaling, damage, and sustain. Core supports include Sunday, Sparkle, Remembrance Trailblazer, and Tribbie for damage buffs and debuff application.
Sustain characters like Huohuo, Gallagher, or Luocha help mitigate his HP consumption and keep him active longer.
Final Thoughts
Mydei offers a unique mix of survivability and high HP-scaled damage, making him a formidable hypercarry DPS.
Prioritizing HP, critical stats, and appropriate team synergies will unlock his true potential. His signature Light Cone and relic sets perfectly complement his playstyle, balancing damage and sustainability.
