Mydei
Yes—Mydei is a strong Imaginary HP-drain Destruction carry. Ultimate “Throne of Bones” Blast-hits the main target plus adjacent enemies. Best with Sunday / Tribbie / Hyacine / Luocha. HP drain wants high healing throughput. Skip when you lack Remembrance/HP-sustain partners.
Mydei is a 5★ Imaginary Destruction Main DPS. Skill “Deaths are Legion, Regrets are None” is the primary in-combat spend. Ultimate “Throne of Bones” is the payoff window for damage or team utility. This Phase 1 page covers kit text, gear targets, and pull notes—team comps stay empty until Phase 2.

Strengths
- Ultimate “Throne of Bones” Blast-hits the main target plus adjacent enemies—most of the kit’s damage lives inside that window, not on filler Basics.
- Skill “Deaths are Legion, Regrets are None” spends HP as a deliberate self-damage cost—the rotation wants controlled self-damage, not panic healing that cancels the state.
- “Blood for Blood” spends HP as a deliberate self-damage cost—cleaving a trash mob can snowball into another full Skill/Ult cycle.
- When you own “A Thankless Coronation”, Mydei’s damage or utility ceiling jumps because the cone was written around this kit’s triggers—not a generic path stick.
Weaknesses
- E0 without “A Thankless Coronation” is still clearable, but the gap versus a signature copy is larger than a single eidolon for most Destruction carries—plan the cone before deep eidolon hunting.
- HP-spend skills mean Mydei can soft-lock if sustain is weak or if a healer tops them up at the wrong time and breaks a low-HP / Charge condition.
- Extra-turn and single-target Ultimate patterns shine on bosses but stall in Pure Fiction unless adds die fast enough to proc the talent loop.
- Spamming “Deaths are Legion, Regrets are None” every turn without watching Skill Points strands the rest of the team—Mydei is often the SP sink.
Trace Priority
Throne of Bones carries most of the kit’s damage or utility—level this first.
Deaths are Legion, Regrets are None supports the main rotation—raise after the top priority traces.
Blood for Blood supports the main rotation—raise after the top priority traces.
Vow of Voyage is last priority outside of filling trace materials.
Stat Priority
Open with Technique if it helps, spend Skill to advance the kit’s resource, and hold Ultimate for the damage or buff window. Exact teammate order lands in Phase 2.
Open supports first, then spend the carry’s Skill/Ult inside the buff window. Exact order varies by the team tab above.
Light Cones
5★ · Path cone
Increases the wearer's CRIT DMG by 0.36%. When using Ultimate, increases the wearer's ATK by 0.4%, and if the wearer's Max Energy is greater than or equal to 300, regenerates a fixed amount of Energy equal to 0.1% of the wearer's Max Energy and once again increases the wearer's ATK by 0.4%, lasting for 2 turns.
Why it works —Signature / best-in-slot when owned—passive lines up with Mydei’s kit triggers.
5★ · Path cone
When the wearer attacks, increases their ATK by 0.08% in this battle. This effect can stack up to 4 time(s). After the wearer breaks an enemy's Weakness, increases DMG dealt by 0.12%, lasting for 2 turn(s).
Why it works —Best accessible option for most accounts—raise superimposition when copies drop.
4★ · Path cone
Increases DMG dealt by the wearer by 0.2%. The wearer also deals an extra 0.2% of DMG to enemies whose current HP percentage is equal to or higher than the wearer's current HP percentage.
Why it works —Budget path cone—fine while building the account.
4★ · Path cone
Increases the wearer's ATK by 0.16%. When the wearer defeats an enemy, the wearer's CRIT Rate increases by 0.12% for 3 turn(s).
Why it works —Budget path cone—fine while building the account.
Relics
Team Compositions
Primary Remembrance / HP team for Mydei. Sunday, Tribbie, Luocha are the partners the kit / endgame clears assume first.
Core carry for this shell — owns the damage plan and sets the rotation pace.
Sunday is the Advance / DMG amp — time their Skill/Ult for the carry’s damage window.
Tribbie is the Advance / DMG amp — time their Skill/Ult for the carry’s damage window.
Luocha covers HP / memosprite upkeep so the Remembrance loop does not collapse mid-wave.
Traces & Eidolons
Traces
Deals Imaginary DMG equal to 70% of Mydei's Max HP to one designated enemy.
Consumes HP by an amount equal to 50% of Mydei's current HP. Deals Imaginary DMG equal to 113% of Mydei's Max HP to one designated enemy and Imaginary DMG equal to 63% of Mydei's Max HP to adjacent targets. If the current HP is not sufficient, using Skill reduces Mydei's current HP to 1.
Restores HP by 22.5% of Mydei's Max HP and accumulates 20 Talent's Charge point(s). Deals Imaginary DMG equal to 192% of Mydei's Max HP to one designated enemy, and deals Imaginary DMG equal to 120% of Mydei's Max HP to adjacent targets. Additionally, Taunts the target and targets adjacent to it, lasting for 2 turn(s). The next use of "Godslayer Be God" prioritizes attacking one designated enemy, and this effect only works on the latest target.
For each 1% of HP lost, accumulates 1 point of Charge (up to 200 points). When Charge reaches 100, consumes 100 points of Charge to enter the "Vendetta" state, restores HP equal to 30% of Mydei's Max HP, and advances action by 100%. While the "Vendetta" state is active, Max HP increases by 50% of the current Max HP and DEF remains at 0. At the start of this unit's turn, automatically uses "Kingslayer Be King." 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.
After using Technique, pulls in enemies within a certain area and inflicts Daze on them for 10 second(s). Dazed enemies will not actively attack ally targets. If actively attacking Dazed enemies, when entering battle, deals Imaginary DMG equal to 80% of Mydei's Max HP to all enemies, and Taunts the targets, lasting for 1 turn(s). This unit accumulates 50 point(s) of Talent's Charge.
Consumes HP by an amount equal to 35% of Mydei's current HP. Deals Imaginary DMG equal to 138% of Mydei's Max HP to one enemy and Imaginary DMG equal to 83% 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.
Consumes 150 point(s) of Charge. Deals Imaginary DMG equal to 350% of Mydei's Max HP to one enemy and Imaginary DMG equal to 210% of Mydei's Max HP to adjacent targets. This ability will be automatically used. While this ability is in use, Charge cannot be accumulated.
Eidolons
Increases the DMG multiplier dealt by "Godslayer Be God" to the primary target by 30%. This ability now deals to all enemies Imaginary DMG equal to the DMG multiplier dealt to the primary target.
Is it worth getting?
Modest E1: Increases the DMG multiplier dealt by "Godslayer Be God" to the primary target by 30%. Helpful padding, not a build-defining unlock.
During "Vendetta," the DMG dealt by Mydei ignores 15% of enemy targets' DEF. After he receives healing, converts 40% of the healed amount to Charge. The tally of the converted Charge cannot exceed 40 point(s). Resets this tally of Charge after any unit takes action.
Is it worth getting?
Defining stop for many accounts: Adds RES PEN (or ignore) during the burst window. Pull here if you main Mydei; this is the eidolon that changes how the kit is played.
Skill Lv. +2, up to a maximum of Lv. 15. Basic ATK Lv. +1, up to a maximum of Lv. 10.
Is it worth getting?
Skill + Basic ATK levels only (+2). Free if you roll into it; never spend currency aiming for E3.
While in "Vendetta," increases CRIT DMG by 30% and restores HP by 10% of this unit's Max HP after receiving attacks from enemy targets.
Is it worth getting?
Side-grade: Flat combat-stat bump tied to a specific trigger. Happy if it drops; not a planned stopping point.
Ultimate Lv. +2, up to a maximum of Lv. 15. Talent Lv. +2, up to a maximum of Lv. 15.
Is it worth getting?
Ultimate + Talent levels only (+2). Skip as a goal—grab it if you overshoot toward E6, never hard-pity for it.
When entering battle, immediately enters the "Vendetta" state, and lowers the Charge required for "Godslayer Be God" to 100 point(s).
Is it worth getting?
Whale ceiling: When entering battle. Only chase if Mydei is your dedicated Destruction main and E0–E2 already feel finished.
Mydei is fully usable at E0. Dedicated mains often stop at E0 before chasing higher. First stop: E0. Endgame target: E0.
