Once a Synchronist at Startorch Academy, she now fights as a digital ghost piloting a mecha, alternating between Tune Rupture and Fusion Burst modes while managing Synchronization Rate for massive damage output.

Her gameplay emphasizes quick rotations, Heavy Attacks in Instant Response state, and core skills like Duet of Seraphic Plumes and Heavenfall Edict - Finale. Early calculations show her teams clearing 2.25+ million team damage in 25-second loops, outpacing many top DPS units.

With her banner live alongside Luuk Herssen, players face the classic gacha dilemma: save for dupes (Resonance Chains/S-sequences) or chase her signature weapon? Let's break it down with kit details, values, and damage insights:

Aemeath's Signature Weapon: Everbright Polestar

Stats (Level 90): 588 ATK, 24.3% Crit DMG.

Passive - Chasing the Stars: Grants 12% All-Attribute DMG Bonus. When applying Shock Deflection or Imbustion Effect, Resonance Liberation DMG ignores 32% of the target's DEF and 10% Fusion RES for 4-8 seconds (sources vary on duration).

This weapon is tailor-made for Aemeath's Res Lib-heavy kit, providing rare multiplicative DEF shred on her biggest hits. Community estimates peg it at a 40-45% personal DPS uplift, making her feel "incomplete" without it. Alternatives like Emerald of Genesis (energy/ATK) or 4-star Feather Edge (10.8% Res Lib DMG) fall short against high-DEF bosses.

Aemeath's Resonance Chains: High Early Value

Aemeath's sequences offer strong personal buffs, with S1-S3 providing direct damage spikes. Unlike some units, her chains enhance core mechanics without heavy team reliance until S4.

SequenceNameKey EffectsValue Notes
S1Gilded Glimmer of the First Dawn+300% Crit DMG on Heavy Attacks in Instant Response; transfers max stacks to new targets on kill; easier out-of-combat activation.Highest early value - massive Crit DMG amp + QoL. Slightly edges sig weapon for main DPS fluidity.
S2Downy Notes of Snowfluff+100% DMG Multiplier on Duet of Seraphic Plumes (Overture/Encore) - effectively doubles it; extra explosion in Fusion Burst on kills.Direct core skill double - huge DPR leap in both modes.
S3Fervor Sightly Burns Bright as NewDoubles Heavenfall Edict - Finale DMG Multiplier; self-activates 60% Crit DMG + 20% DEF Ignore buff (no team req).Game-changer for solo potential; biggest single ult boost.
S4Ethereal Waltz on Binary Tides20% All-Attribute DMG Bonus to team for 30s on Intro/core skills.Strong team support; endgame luxury.
S5Voyage to the Astral ShoreResets mecha flight stamina on kills; 1x revive with team shield (10min CD).Exploration/survivability - low combat value.
S6A Zephyr-Kissed Journey to YouEnemies take +40% Res Lib DMG; fixed 80% CRIT Rate/275% CRIT DMG on Tune Rupture/Fusion Burst; doubles Trail stacks.Ultimate ceiling - multiplicative monster.

Priority: S1 > S2 > S3. Early chains rival the sig's impact, especially S1's 300% Crit DMG on Heavies.

Damage Calculations and Comparisons

Theorycrafter ChemX32's spreadsheet (via Fractured Shores) highlights Aemeath's team potential in 25s loops (all C0 Aemeath assumed, premium supports S1):

Team SetupSlot 1 (Aemeath?)Slot 2Slot 3Total Team DMG
Lynae S1 + Mornye S1 (2x Rupture)1,589,145571,584112,5662,273,296
Lynae S1 + Mornye S1 (1x Rupture)1,555,089461,35795,0862,111,532
Lynae S0 Mist + Mornye S0 (1x)1,379,490390,46864,4631,834,421
Lynae S1 + Chisa S11,085,783390,876326,9361,803,595
Lupa S1 + Mornye S11,320,218395,788104,3871,776,484
Changli S1 + Lupa S1 (longer rot.)994,521500,269272,2691,767,059

Lynae/Mornye reigns supreme for Rupture mode; Shorekeeper lags due to stack competition. No direct C0R1 vs C1R0 in these, but S1 Mornye adds ~200k team DMG vs S0.

Qualitative TC consensus: Sig weapon ~40% personal DPS (DEF ignore scales hard late-game). S1 ~equivalent via Crit DMG + stacks/QoL; S1+S2 ~sig value combined. S2 doubles a key skill for reliable gains.

Verdict: Prioritize Signature Weapon (With Caveats)

Pull the weapon first. Its DEF/Fusion RES shred is irreplaceable for Aemeath's Res Lib spam, delivering 40%+ DPS in bossing where alternatives falter. F2P/low-spenders: Guarantee C0R1 for meta dominance; skip dupes unless whale-saving.

Dupes if... You lose 50/50 on her - chase S1 over weapon rerun (comparable value, better QoL). S2/S3 push her to top-1 DPS; S6 is luxury god-mode.

Ideal: C0R1 + S1 for broken synergy. Skip if saving for Luuk/Chisa teams, but Aemeath defines 3.1 powercreep.
