Update: Mydei’s HSR build, kit, and materials has been updated on February 15, 2025.
Honkai Star Rail just added Amphoreus in the recent update and it introduced a set of completely new characters. Mydei is one of the newly introduced characters in Amphoreus, a Chrysos Heir and the rightful king of Castrum Kremnos. He has an Undying body as part of the Chrysos Heir curse and is considered a rival to Phainon. His kit and other playable details have been revealed, so here I have added everything we know about Mydei. Here is the complete guide to Mydei’s build, kit, materials, signature light cone, eidolons, and base stats in HSR.
Honkai Star Rail Mydei Build
Here is how you can build Mydei with his best Relics, Planar Ornaments, Stats, Light Cone, and Teams:
- Relic: Scholar Lost in Erudition (4-piece)
- Planar Ornament: Bone Collection’s Serene Demesne
- Main Stats: Crit Rate or Damage (Body), Speed (Boots), HP % (Sphere), HP % (Link Rope)
- Light Cone: Flame of Blood, Blaze My Path (5-star), Ninja Record: Sound Hunt (4-star)
- Team: Mydei, Tribbie, Sunday, Luocha
If you want more options for Mydei’s relics, planar ornaments, stats, light cones, and teams, then check out the individual sections below.
HSR Mydei Build: Best Relics
- Scholar Lost in Erudition (4-piece)
- Longevous Disciple (4-piece)
The Scholar Lost in Erudition is the best in-slot relic set for Mydei, especially if you have Sunday in the team. This relic set provides a ton of Crit Rate to the wearer, and also increases the damage dealt by Ultimate and Skill by 20%, which are the main damage sources for Mydei.
Other than that, Longevous Disciple is another great option you can use on Mydei. It increases the Max HP for the wearer and also increases their Crit rate after getting hit.
HSR Mydei Build: Best Planar Ornaments
- Bone Collection’s Serene Demesne
- Fleet of the Ageless
The new Planar Ornament set, Bone Collection’s Serene Demesne is currently the best Planar Ornament for Mydei. This Planar Ornament increases the Max HP of the wearer and increases Crit Damage by 28% if the wearer has a Max HP of 5000 or higher, which is always going to be the case for Mydei.
Other than that, you can use Fleet of the Ageless which increases the HP for the wearer and also increases the Attack of the allies.
Mydei Build: Main and Sub Stats for Relics
- Body: Crit Damage %
- Boots: Speed
- Planar Sphere: HP %
- Link Rope: ERR %
- Sub-stats: HP % (8000) > Crit Rate (above 70%) > Crit Damage (above 160%) > Speed (134 plus)
When it comes to Mydei’s stats, you need to prioritize on getting 8000 Max HP to get the full benefit of his passive. After that, get as much Crit Damage and Crit Rate as possible. Other than that, you need to get to 134 Speed breakpoint on him.
Effect Resistance is basically useless on Mydei as he becomes immune to Crowd-control debuffs after entering the Vendetta state.
Best Light Cones for Mydei Build in HSR
- Flame of Blood, Blaze My Path
- The Unreachable Side
- Ninja Record: Sound Hunt
- Flames Afar
- A Secret Vow
- On the Fall of an Aeon
Mydei has many different options for light cone as he is a Destruction unit. The best light cone for Mydei is his signature, Flame of Blood, Blaze My Path. We have given more information on this Light Cone later in the article.
Other than that, you can also use Blade’s signature Light Cone on Mydei, The Unreachable Side. For 4-star light cones, Ninja Record: Sound Hunt is the best in-slot option. Flames Afar, A Secret Vow, On the Fall of an Aeon, are also good Light Cone options for Mydei.
Best Mydei Teams in Honkai Star Rail
- Best: Mydei, Tribbie/Robin, Sunday, Luocha
- Alternative: Mydei, Bronya/Sparkle, Remembrance Trailblazer, Lingsha
- Mydei No Sustain: Mydei, Tribbie, Sunday, Remembrance Trailblazer
- F2P: Mydei, Hunt March 7th, Remembrance Trailblazer, Gallagher
Mydei’s best build has some strong team variations. His best team will feature Tribbie, Sunday and Luocha. As a Hypercarry, you will need someone like Bronya or Sunday with him to get the best out of his kit. Sparkle can also work well if you don’t have anyone else.
Other than that, Remembrance Trailblazer and March 7th can also act as a good sub-dps or support for Mydei.
Honkai Star Rail Mydei Release Date
Mydei is going to release in Honkai Star Rail 3.1, confirmed officially by his Drip Marketing and 3.1 Livestream. He will feature in the 2nd half of the banners, the first half featuring Tribbie. Huohuo will feature alongside Mydei as a rerun in the second half. If the current 42-day version cycle remains unchanged, then Mydei will be released on March 19, 2025.

Honkai Star Rail Mydei Kit
HSR Mydei’s kit has been revealed officially and he is going to be a strong DPS with self-sustaining abilities. Here is everything we know about Mydei’s HSR kit:
- Basic Attack (Vow of Voyage): Deals single target Imaginary Damage equal to 50% of Mydei’s Max HP.
- Skill (Deaths are Legion, Regrets are None): Consumes 50% of Mydei’s current HP and deals blast damage equal to 90% of his Max HP to the primary target and 50% of his Max HP to adjacent targets. If the current HP is not sufficient, the Skill reduces Mydei’s current HP to 1.
- Ultimate (Throne of Bones): Restores HP equal to 20% of Mydei’s Max HP and accumulates 20 Talent charge points. Deals Blast Imaginary Damage equal to 160% of Mydei’s Max HP to the primary target and 100% of Mydei’s Max HP to adjacent targets, with a 100% base chance to Taunt the target and their adjacent targets, lasting for 2 turn. The next use of “Godslayer Be God” prioritizes attacking one designated enemy, and this effect only works on the latest target.
- Talent (Blood for Blood): For each 1% of HP lost, accumulates 1 point of Charge (up to 200 points). When Charge is full, enters the “Vendetta” state, restores HP by 25% of Mydei’s Max HP, and advances action by 100%. While in ‘Vendetta’, Mydei increases Max HP by an amount equal to 50% of the current Max HP, maintains 0 Defense. When Charge reaches 150 points during the “Vendetta” state, Mydei immediately gains 1 extra turn and automatically uses “Godslayer Be God.” When receiving a killing blow during the “Vendetta” state, Mydei will not be knocked down, but will clear his Charge, exits the “Vendetta” state, and restores HP by 50% of his Max HP.
- Enhanced Skill (Kingslayer Be King): Consumes HP by an amount equal to 35% of Mydei’s current HP. Deals Imaginary Damage equal to 110% of Mydei’s Max HP to one enemy and Imaginary Damage equal to 66% of Mydei’s Max HP to adjacent targets. If the current HP is not sufficient, using Skill reduces Mydei’s current HP to 1. This ability will be automatically used.
- Enhanced Skill 2 (Godslayer Be God): Consumes 150 points of Charge. Deals Imaginary Damage equal to 280% of Mydei’s Max HP to one enemy and Imaginary Damage equal to 168% of Mydei’s Max HP to adjacent targets. This ability will be automatically used. While this ability is in use, Charge cannot be accumulated.
- Technique (Cage of Broken Lance): Pulls enemies within a certain area and inflicts Daze on them for 10 seconds. Dazed enemies will not actively attack ally targets. If actively attacking Dazed enemies, when entering battle, deals Imaginary Damage equal to 80% of Mydei’s Max HP to all enemies, and Taunts the targets, lasting for 1 turn. This unit gains 50 points of Talent Charge.
- Trace 1 (Earth and Water): When Mydei receives Fatal damage during the ‘Vendetta’ state, he won’t exit the Vendetta state. This effect can trigger 3 times per battle.
- Trace 2 (Thirty Tyrants): During “Vendetta,” Mydei is immune to Crowd control debuffs.
- Trace 3 (Bloodied Chiton): If Mydei’s Max HP exceeds 400 when battle starts, for every 100 excess HP, increases this unit’s CRIT Rate by 1.2%, his Charge ratio from enemy targets’ damage increases by 2.5%, and his Incoming Healing increases by 0.75%. Up to 4000 excess HP can be taken into account for this effect.
- Trace Stat Boosts: 37.3% Crit Damage Boost, 5 Speed, 18% HP Boost
Mydei’s kit is a perfect mix of a sustain and a DPS. He has very strong self-sustaining abilities, and can even survive fatal blows when in the Vendetta state. He completes scales on his Max HP and attacks on his own in his Vendetta state. Overall, Mydei’s current kit appears very interesting, and it would be great to have another health-draining mechanic character in the game.

Mydei Signature Light Cone in HSR
Mydei’s Signature Light Cone has also been revealed and its name is ‘Flame of Blood, Blaze My Path’. This Light Cone increases Max HP and incoming healing for the wearer. Additionally, it increases the damage of the character based on the amount the HP consumed, making it perfect for Mydei and Blade as well.
Name Flame of Blood, Blaze My Path Rarity 5-star Base HP 1376 Base Attack 476 Base Defense 397 Path Destruction Effect Increases the wearer’s Max HP by 18% and Incoming Healing by 20%. When using Skill or Ultimate, consume HP equal to 6% of the wearer’s Max HP and increases the Damage dealt by this attack by 30%. If this effect’s consumed HP is greater than 500, additionally increases this attack’s damage by 30%. If the current HP is not sufficient, this effect can reduce the wearer’s HP down to a minimum of 1.
Honkai Star Rail Mydei Eidolons
Here are all the details about the eidolons of Mydei in Honkai Star Rail 3.1.
- E1 (Frost Homes Spine of Steel): The damage multiplier applied by “Godslayer Be God” to the primary target increases by 30%. And “Godslayer Be God” becomes Imaginary damage dealt to all enemies equal to the DMG multiplier applied to the primary target.
- E2 (Strife Beholds Cry of Dead): During “Vendetta,” the Damage dealt by Mydei ignores 15% of enemy targets’ Defense. And when receiving healing, converts 40% of the healed amount to Charge. The tally of the converted Charge cannot exceed 40 points. Resets this tally of Charge after any unit takes action.
- E3 (Honor Exalts Feast of Faith): Skill Level + 2, Basic Attack Level + 1

So far this is all the information we have on Mydei’s kit, materials, and signature light cone. Tell us what you think about the undying Chrysos Heir and whether you prefer him over Blade in Honkai Star Rail.
