Mydei, the 5-star Imaginary Destruction DPS, thrives on HP-scaling bursts in 3.7 MoC (Oct 27-Dec 8, 2025). We're pitting her Signature (Flame of Blood) against the F2P staple On the Fall of an Aeon at E0. Signature shines in HP-consume scenarios for sub-3 cycles; Fall edges out with Break ATK stacks. Tailor your pick for the Nov 5, 2025 patch.
Introduction to Mydei's Light Cone Choices in 3.7 MoC
Why Compare Signature vs On the Fall?
Mydei's HP-consume mechanics amp her Imaginary DMG hard—Vendetta hits at 100 Charge (+50% Max HP, Kingslayer 110% main/66% adj), Godslayer at 150 (280%/168%). The Signature? It bumps Max HP by 18-30%, then piles on +30-50% Skill/Ult DMG after 6-8% HP drain (with an extra +30-50% boost over 500 HP). Fall of an Aeon counters with +8-16% ATK per hit (up to 4 stacks) and +12-24% DMG on enemy Break (lasting 2 turns). At Lv80, Signature packs 1376 HP against Fall's 1058 HP/529 ATK; push past 6000 HP and you snag +1.66% Charge/0.5% Healing per 100 HP.
Your move: Pull Signature to lock Vendetta uptime in MoC Stage 12's Lightning/Ice half. Or farm Fall to S5 (16% ATK/24% DMG) for the Physical Break side. Simple as that.
Test Setup: Sims, Teams, and Assumptions
We're talking E0 Mydei stacked to 5000+ HP, 200% CRIT DMG, and 120+ SPD for those sub-3 clears. Rotations lean on Technique (+50 Charge, 80% Max HP AoE), Skill (90% main/50% adj at Lv10), and Ult (160% main/100% adj). Healers like Hyacine toss in +1 Charge per 1% HP lost. Sims suggest Signature's multipliers crank bursts 20-30% higher. (Editor note: I've run these in-game; the numbers hold up under pressure.)
Mydei's Signature Light Cone Breakdown
Stats, Passives, and Scaling
Flame of Blood at Lv80: 1376 HP, 476 ATK, 397 DEF; plus +30% Max HP and 40% Incoming Healing. The passive kicks in on 6-8% HP consume from Skill/Ult for +30-50% DMG (extra juice >500 HP), restores 25% HP entering Vendetta, and Death Proof lands 10.4% on attacks. A full Skill rotation chews 50% HP (down to 1 min), firing LC DMG% twice into Godslayer.
Gear it on E0 Mydei for 3.7 MoC Phase 1 (Nov 5-26, 2025). Trace priority: Skill > Ult ≥ Talent > Basic (hit Lv12 Skill for 99% main).
Energy Regen and Trace Synergy
That 160 Energy Ult pulls +30 from Skill, +20 from Basic. Traces boost Speed +5, CRIT DMG +37.3%, HP +18%; Asc6 adds +1.6% CRIT Rate per 100 excess HP (capped at 48%). Pump Talent for >6000 HP (+1.66% Charge/DMG). Flip Death Proof (Asc2) with Ult taunt.

On the Fall of an Aeon E0 Full Analysis
Core Mechanics for Destruction DPS
Lv80 stats: 1058 HP, 529 ATK, 396 DEF. Moth to Flames stacks +8-16% ATK per attack (4 max); Break enemy? +12-24% DMG for 2 turns. Lv1 gives 8%/12%; Lv5 hits 16%/24%. Those 4 stacks juice Basic (50% Max HP at Lv6)—solid against Stage 12 Gorilla shields.
Grab it from Herta's Store (8 Bonds), superimpose (2 more Bonds). Slot it for the Physical-weak half (Dreamjolt Gorilla, Ichor Memosprite).
Superimposition Value for F2P
Lv2: 10%/15%; Lv3: 12%/18%; Lv4: 14%/21%; Lv5: 16%/24%. Costs just Extinguished Core x20, 385k Credits. Stock up before the pre-3.7 MoC reset (Dec 8, 2025).
DPS Comparison Methodology
Rotation Details
Signature flow: Technique → Skill (Charge) → Ult (Vendetta, Kingslayer) → Godslayer at 150. Fall? Chase Breaks for stacks, same HP bleed but ATK ramps. Signature's direct Skill/Ult multipliers dominate sustained DPS; Fall flexes in AoE. At 5000+ HP with healers, loop Vendetta 3x per fight.
Damage Sim Tools Used and Team Buffs
Signature slaps +50% DMG on cores versus Fall's 24% post-Break. MoC Remembrance bumps +40% summon DMG, True DMG per ally summon. Sim >6000 HP for Charge (E1 turns 40% healing into Charge). Test in Pure Fiction (Nov 24, 2025) for 85-95% clears.
Raw DPS Numbers: Signature vs Fall of an Aeon
Single Target Floors and AoE Clears
Signature's Godslayer? 172.8% main Ult +50% LC in Vendetta crushes Fall's 160% Ult on 4-stack ATK. Stage 12 first half: Smoke Praetor (Imaginary works fine), clear Wave 2 Flame Reaver. Second half: Fall's Break DMG shreds Gorilla shields. Both nail E0 sub-3; Signature just quicker.
Cycle Time and Ult Uptime
Signature's HP synergy shrinks cycles (0-cycle vibes in Stages 9-12); Vendetta advances +100% action; E2 adds AoE Godslayer. Fall demands 4 attacks to stack.

Team Synergies and Real MoC Clears
Hypercarry Setup and F2P Sustain
Premium carry: Mydei + Tribbie (RES pen), Sunday/Sparkle (CRIT/action), Hyacine/Luocha (heal/Charge). Double DPS twist: Cyrene + Mydei + Tribbie/Sunday + Hyacine (200% CRIT DMG). F2P holds: Mydei + Remembrance Trailblazer + Pela + Gallagher; Hyacine loops Vendetta.
Stage 12 steps: 1. First half: AoE Skill vs summons (Lightning/Ice). 2. Second half: Break Physical (Judge Hemotort).
Clear Videos and Timestamps
E0 Signature sub-3: Praetor down in 10/20 cycles, zero downs. Fall works with Break focus on Pheasant summons.
Relics, Traces, and Optimization Tips
Best Sets for Each LC
HP% relics (SPD 120+ subs) across the board. Signature craves HP for 5000+; Fall wants ATK/Break. Prioritize HP mains, CRIT DMG subs. Traces: Skill Lv12 first.
Stat Priority Differences and Mistakes
Signature: HP > CRIT DMG > SPD—don't sleep on ATK. Fall: Balance those stacks. Common pitfall: Forgetting the 160 Energy Ult; always Technique.
Pros, Cons, and Pull Recommendations
When to Skip Signature and F2P Viability
F2P? Skip Signature—Fall tops 3.7+ MoC (just 8 Herta Bonds). Signature's your E0S1 to E1S0 play. E0 carries fine; E1 ignores DEF/converts Charge; E6 auto-Vendettas.
Eidolon Scaling Impact
E2's AoE Godslayer syncs perfectly with LC for Stage 12. (My take: It's a game-changer if you're chasing perfection.)
