Mydei Trace Priority
Focus on unlocking Mydei's Major Traces first, followed by ability upgrades:
- Major Trace 1 (Earth and Water): Survive lethal damage in Vendetta state which is critical for survivability since he consumes a lot of HP during this state.
- Major Trace 2 (Thirty Tyrants): Grants immunity to Crowd Control debuffs which might help with enemies that have a lot of Crowd Control (Kafka, Aurumaton, etc).
- Major Trace 3 (Bloodied Chiton): Grants CRIT RATE based on excess HP (up to 48% at 4000+ HP) which makes building him much easier.
Mydei relies mostly on his Skill and Ultimate to maximize the damage output he dealt while still having his Ultimate recovers more HP. To maximize his potential, focus on upgrading his Skill and Ultimate with his Talent next. His Basic ATK is the least important trace since he never use his Basic ATK during Enhanced State. In short, his trace priority is Skill > Ultimate > Talent > Basic ATK.

Mydei Recommended Teams
a. Hypercarry Team
Mydei works well in a hypercarry team with supports that synergize well with HP scaling DPS such as Sunday, Sparkle, Remembrance Trailblazer, etc. It is important to note that Mydei will need some help with sustaining his HP consuming abilities (the more HP% he consumes, the faster he uses his Enhanced Skill 2) so you will need to bring at least 1 sustain in a non-zero cycle. Sunday works well with Mydei since Sunday increases a lot of DMG%, CRIT DMG, SP generation, and energy that helps Mydei uses his Ultimate to heal himself more often. Sparkle works the similarly as Sunday but it is recommended to use Slow Mydei with Sparkle since her Advance Forward is only 50% compared to Sunday who has 100% Advance Forward. Remembrance Trailblazer also works well with him due to True DMG, CRIT DMG, SP positive, and Advance Forward. The new upcoming character Tribbie is also good for Mydei since Tribbie increases the RES PEN of the team and has a Vulnerability field which is good for HP scaling DPS. For sustain, you can use Huohuo for energy, Gallagher that can heal whenever an ally attacks the Besotted state, or Luocha that has a field which heals the team whenever any ally attacks.
Main DPS: Mydei
Support 1 & 2: Tribbie / Remembrance MC / Sparkle / Sunday
Sustain: Huohuo / Gallagher / Luocha

Conclusion
Mydei stands as a formidable 5-star Imaginary Destruction character, excelling as a hypercarry DPS with unparalleled survivability and damage output. His unique playstyle revolves around balancing self-sustain with high-risk, high-reward mechanics, making him a dynamic and engaging addition to any team. By strategically consuming his own HP to fuel his Enhanced Skill and Vendetta state, Mydei transforms into a relentless force capable of decimating enemies while maintaining remarkable durability. This guide has outlined the essential components to optimize his performance, from trace priorities to team synergies, ensuring players can harness his full potential.
Central to Mydei’s effectiveness is his reliance on HP management. His Major Traces, such as Bloodied Chiton (granting up to 48% CRIT Rate based on excess HP), emphasize the importance of stacking Max HP while balancing survivability and damage. Prioritizing his Skill and Ultimate upgrades ensures consistent access to his Enhanced State, where his damage peaks. Light Cones like Flame of Blood, Blaze My Path synergize perfectly with his kit, amplifying his HP scaling while compensating for his self-inflicted HP drain. Alternatives such as The Unreachable Side or A Secret Vow offer flexibility, catering to players seeking CRIT boosts or situational damage multipliers.
Equipping the right Relics and Planar Ornaments further elevates Mydei’s prowess. The Scholar Lost in Erudition set enhances his Skill and Ultimate damage, while Longevous Disciple provides CRIT Rate stacks through HP consumption, both aligning with his aggressive playstyle. Planar Ornaments like Bone Collection’s Serene Demense (for HP-focused builds) or Rutilant Arena (for CRIT-heavy setups) allow players to tailor his stats to their team’s needs. Stat priorities should prioritize CRIT DMG on the Body, SPD or HP% on Feet, and HP% on the Link Rope, ensuring a balance between speed, survivability, and burst potential.
Team composition is critical for Mydei to thrive. Hypercarry teams benefit from supports like Sunday or Sparkle, who amplify his damage through Advance Forward mechanics and CRIT boosts. Sustain units like Huohuo or Gallagher mitigate his HP drain, ensuring he remains active in prolonged battles. The synergy between Mydei and characters like Remembrance Trailblazer or Tribbie further enhances his utility, offering RES PEN or Vulnerability debuffs to maximize his damage ceiling.
In summary, Mydei’s strength lies in his adaptability and raw power, but mastering him requires careful attention to gear, stats, and team dynamics. By investing in his traces, optimizing his Light Cones and Relics, and pairing him with synergistic supports, players can transform Mydei into an unstoppable force.
