Light Cone
Flame of Blood, Blaze My PathFlame of Blood raises Max HP and incoming healing, then consumes HP to amplify each Skill and Ultimate attack.
When to use it : Do not pair its HP-loss play pattern with persistent shields; Mydei must actually lose HP to cycle Charge cleanly.
A Secret VowA Secret Vow gains its stronger damage bonus while Mydei remains below an enemy's HP percentage.
Ninja Record: Sound HuntNinja Record raises Max HP by 12% and grants 18% CRIT DMG for two turns when Mydei loses or restores HP, once per turn.
Flames AfarFlames Afar restores HP after a large loss and grants a damage bonus that Mydei refreshes naturally through self-consumption.
It is a permanent Forgotten Hall shop cone, so copies are obtained without limited Warps.
Relics
Scholar increases CRIT Rate and the Skill and Ultimate damage that dominate Mydei's Vendetta cycle.
When to use it : Use the Ultimate before a Skill or automatic enhanced sequence to capture Scholar's post-Ultimate bonus.
Longevous Disciple gains CRIT Rate after Mydei consumes HP.
Planar Ornaments
Bone Collection supplies HP and CRIT DMG at a threshold Mydei exceeds while pursuing his 8,000-HP Trace cap.
When to use it : Reach 5,000 HP before combat so Bone Collection's full 28% CRIT DMG is active from the first turn.
Rutilant Arena supports Skill damage after its CRIT Rate requirement is met.
Five allied follow-up attacks unlock Duran's 25% CRIT DMG for Mydei; its follow-up damage bonus does not apply to his automatic Skills.
Team lineup
Tribbie amplifies HP-scaled area damage, Remembrance Trailblazer advances Mydei's decisive action, and Luocha sustains repeated self-consumption without blocking it.
When to use it : Use Luocha's reactive healing instead of shields so Mydei safely loses and restores HP throughout Vendetta.

Mydei spends HP to build Charge, enters Vendetta at 100, then cycles automatic Kingslayer and Godslayer attacks while allies keep him alive.
Common build decisions
These answers explain the guide's stated mechanics and assumptions. Equipment comparisons are not measured damage tests.
Practical answers added :
What changes if I use the accessible cone instead of Flame of Blood?
Flames Afar restores HP after a large loss and grants a damage bonus, but it does not provide Flame of Blood's Max HP, healing bonus or HP-consuming amplification. Recheck the 8,000 sheet HP goal and survivability after changing cones. The guide does not claim a measured damage gap between them.
Compare the cone conditionsWhy can a well-equipped Mydei still enter Vendetta slowly?
Persistent shields can prevent the HP loss that feeds his Charge cycle. Use healing that lets him safely lose and recover HP, then verify 100 Charge for Vendetta and the later 150-Charge extra action. At 8,000 HP, his own Trace adds 48% CRIT Rate, so 52% on the sheet already reaches 100% without teammate buffs.
Check HP and CRIT targetsHow to play it
- 1Use Skill to consume HP and reach 100 Charge; heal only enough to preserve the next safe self-consumption.
- 2At 100 Charge, enter Vendetta; Kingslayer then fires automatically at the start of Mydei's turn. Continue building toward the 150-Charge Godslayer extra action.
- 3Use the Ultimate to mark the priority target and gain Charge. Its damage always scales with Max HP, which Vendetta increases.
Sources and methodology
Editorial recommendations are written from released game data, then cross-checked against specialist calculations. They are not copied from a single tier list.
Review method
Prydwen and StarGuide were read independently and checked against the released local 4.4 kit. The 8,000 HP breakpoint activates the full self-Trace CRIT conversion; the listed effective cap adds that self-buff but no external CRIT Rate buff. Rotation accounting includes Skill HP consumption, Vendetta entry at 100 Charge, Kingslayer at the start of Mydei's turn, the 150-Charge Godslayer extra action, and the Ultimate's HP-based damage, Charge and marked-target behavior. Shields are not counted as healing and can obstruct HP-loss generation.
