The Version 3.1 update of Honkai: Star Rail releases the much anticipated 5-star character Mydei. Mydei is a Imaginary character following the Path of Destruction. This Honkai: Star Rail Mydei Build Guide will help you get the most out of his abilities by offering a detailed breakdown of his skills and recommending the best configurations to optimize his performance.
Mydei Gameplay
Mydei is a hypercarry unit that excels in consuming HP to fuel his devastating Godslayer attacks. His kit revolves around his turn rate, HP consumption, and buff uptime while ensuring he remains effective in combat.
Basic Attack
Mydei’s basic attack deals Imaginary damage to a single enemy based on his max HP.
Skill
Mydei’s first skill, Deaths are Legion, Regrets are None, consumes half of his current HP to deal heavy damage to one enemy and lower damage to nearby enemies. If he doesn’t have enough HP, this skill will leave him with just 1 HP.
Mydei has an automatic second skill called Kingslayer Be King, which works similarly to his first skill but consumes 35% of his current HP. It deals stronger damage to one enemy and more damage to nearby targets. If he doesn’t have enough HP, it also reduces him to 1 HP.
Another automatic third skill, Godslayer Be God, activates when he has 150 Charge points. It deals massive damage to a single target and high damage to nearby enemies, but while it’s active, it cannot gain more Charge.
Ultimate
Mydei’s ultimate restores some of his HP, gives him 20 Charge points and deals heavy Imaginary damage to one enemy and decent damage to nearby targets. It also forces those enemies to target him for two turns. The next time he uses Godslayer Be God, it will focus on the most recently attacked enemy.
Technique
His technique, Cage of Broken Lance, pulls in nearby enemies and stuns them for a short time. If he enters battle against stunned enemies, he deals Imaginary damage to all of them, taunts them for one turn, and gains 50 Charge points.
When leveling Mydei’s abilities, prioritize Skill > Ultimate >Talent > Basic Attack
Traces
- Earth and Water: This Trace gives a boost to Mydei’s “Vendetta” state. He will not exit the “Vendetta” state when receiving a killing blow.
- Thirty Tyrants: While in the “Vendetta” state, Mydei is immune to Crowd Control debuffs.
- Bloodied Chiton: This Trace increases Mydei’s Max HP, Mydei’s CRIT Rate, his Charge ratio from enemy targets’ DMG, and his Incoming Healing.
Among the Traces, priority should be Bloodied Chiton > Earth and Water > Thirty Tyrants

Honkai Star Rail Mydei Best Relics and Planar Ornaments
Mydei is all about using his skills and Ultimates frequently, as such keep in mind that he is an HP-based DPS unit. In this section of Honkai: Star Rail Mydei Build Guide we will discuss what relics, main stats, and planar ornaments you need to focus on for Mydei.
Prioritize maxing his HP till you hit at least 8k HP, afterwards focus on other stats.
- Body (HP/Crit%)
- Feet (Speed>HP)
- Planar Spear (HP%/DMG)
- Link Rope (HP)
Relic Set
| Scholar Lost in Erudition | The 4-piece Scholar Lost in Erudition is the optimal choice for Mydei. Mydei is all about using his skills and ultimates frequently, making this set his best choice. The set enhances his playstyle by providing the necessary boosts for his abilities. |
| Longevous Disciple | If you cannot get a full Scholar set, the next best options are Longevous Disciple or a mix of two-piece sets that offer useful bonuses. However, the Scholar set is so powerful that farming should be a top priority. |
Planar Ornaments
| Bone Collection’s Serene Demesne | For Planar Ornaments, Mydei works best with this planar ornament which complement his damage potential seeing as how it scales with his Max HP. |
| Rutilant Arena | Rutilant Arena increases the wearer’s CRIT Rate. When the wearer’s current CRIT Rate reaches 70% or higher, DMG dealt by Basic ATK and Skill increases as well. |
Honkai Star Rail Mydei Best Light Cone
| Flame of Blood, Blaze My Path (Mydei’s 5-Star Signature) | Mydei’s signature light cone is by far his best option. It provides the highest base HP among all light cones, additional max HP, and an incoming healing buff. More importantly, it introduces a new mechanic that allows Mydei to consume HP when using skills or his ultimate, enhancing his charge accumulation and overall power. Additionally, it grants a massive 60% DMG buff to attacks that consume HP, making it significantly stronger than standard limited 5-star light cones. |
| The Unreachable Side (5*) | If you do not have his signature light cone, the next best option is Blade’s light cone, which also benefits from HP scaling. |
| A Secret Vow (4*) | Increases DMG dealt by the wearer. The wearer also deals an extra DMG to enemies whose current HP percentage is equal to or higher than the wearer’s current HP percentage. |
| Ninja Record: Sound Hunt (4*) | Increases the wearer’s Max HP. When losing or restoring this unit’s HP, increases CRIT DMG by lasting for 2 turns. This effect can only trigger once per turn. |
Best Team Comps for Mydei in Honkai Star Rail
Mydei is a hypercarry unit that excels in consuming HP to fuel his devastating Godslayer attacks. His best teams maximize his turn rate, HP consumption, and buff uptime while ensuring he remains effective in combat. Below is a breakdown of his optimal team setups and synergies.
Sunday is his absolute best first support. More turns mean more HP consumption, Charge gain, and Godslayer attacks. Sunday provides the best hyper buffs in the game with long durations and extra energy, ensuring Godslayer targets the right enemies.
- Remembrance MC (RMC) or Sparkle are both viable alternatives to Sunday. RMC can provide strong action advance buffs, while Sparkle enables a hyperspeed setup.
- Tribbie is the best second support due to its high uptime and powerful damage amplification. She avoids focusing on ATK buffs, which are redundant and instead provides unique multipliers to enhance Mydei’s damage.
For sustainers, Luocha and Gallagher shine here due to Mydei’s frequent attacks. However, if your supports need team-wide healing, Luocha remains a strong choice.
Is Mydei worth pulling in HSR
Mydei is an incredibly strong DPS in Memory of Chaos (MOC). His ability to take numerous turns makes him a top-tier pick in this game mode. However, in Pure Fiction, he is underwhelming. Despite various team attempts, he struggles to exceed sufficient damage in this mode. At E1, his performance has improved significantly, but this requires additional investment.
In Apocalyptic Shadow, Mydei performs decently but isn’t the best. This suggests he will perform better against other bosses in the future, and upcoming showcases may highlight his potential in different matchups.
If you’re considering pulling for him, he is an excellent hypercarry for MOC but has situational effectiveness elsewhere. With careful team-building and investment, Mydei can become one of the strongest DPS options in the game. His mechanics and synergy requirements make him unique, and future content may further elevate his potential.
