Aurelia Complete Build Guide: Free A-Rank Main DPS from 14-Day Login + Stellar Veil S-Rank Arc & Cadenza Mechanic

Key answer: Aurelia is the free A-rank Main DPS gifted by the 1.0 14-day login event — the character on Day 3 + the S-rank signature Arc “Stellar Veil” on Day 10, the highest value-for-effort free combo of the entire launch. Element Psyche, Arc type Plasma, JP CV Karin Takahashi, former band member of the Tamamochi Street Resident Association. Her core mechanic is Cadenza (a 12-second output window + seamless uptime from A2). The A-rank damage ceiling, and paired with the Devil’s Blood: Curse 4-piece she can clear the main story completely F2P.

Commuting on a giant jellyfish, former Tamamochi Street band member, the moon jellyfish whose scientific name is Aurelia aurita — Aurelia is dubbed across the whole community as “a free A-rank used as a Main DPS”, “a gift to F2P players”, and “the textbook free Main DPS”. This guide lays out her mechanics, gear, Eidolons, recommended teams, and build path all in one place.

1. Character Basics

Item	Details
Name	Aurelia
Rarity	A-rank (standard banner)
Element	Psyche
Arc type	Plasma
Role	Main DPS
Gender / Birthday	Female / March 9
JP CV	Karin Takahashi (Vladilena in “86”)
EN CV	Kira Buckland
CN CV	Ge Zirui (in-game version takes precedence)
Backstory	A member of the “Tamamochi Street Resident Association”, and a former band member who once played in a short-lived but lively band alongside Sakiri. Not a member of BAC or the Interstellar Express
How to get	Launch 14-day login event: Aurelia is auto-gifted on Day 3, and her signature Arc “Stellar Veil” on Day 10

Origin of the Name

Aurelia is taken from the moon jellyfish’s scientific name, Aurelia aurita, which is why she has a jellyfish-themed identity. She is most famous for commuting through the skies above Hezero on a giant jellyfish, and the locals even established a fun precedent that “riding a jellyfish doesn’t count as a violation”.

2. Skill Kit (Music Theme)

Skill type	Name	Mechanic highlights
Basic Attack	Cappella / Legato	4-hit Psyche combo, the main damage source (70-80% of total output)
Dodge	Staccato	Hold dodge to ride the jellyfish in flight; with enemies nearby it auto-fires jellyfish shots, damage +70% in the Cadenza state
Aerial attack	Portamento	Aerial swing-down dive, landing AoE damage
Lethal counter	Syncopation	Basic Attack after a perfect dodge, AoE damage + applies a stagger debuff
Shift (E)	Cadenza Aria ⭐	AoE damage, enters the Cadenza state for 12 seconds, 15-second CD (always open with it)
Assist	Dissonance	Jellyfish-rush AoE damage, key to maintaining Cadenza after Eidolon 2
Ultimate (Q)	Canon Chorus	6-hit AoE damage + gathers enemies, 120 energy
Passive	Crescendo	Each jellyfish-shot hit grants ATK +1%, up to 10 stacks (raised to 20 at A6)
Passive 2	Harmonics	Deals extra Psyche damage when Nova ends

Core Rotation

E (enter Cadenza) → Basic Attack (Cappella) to stack Crescendo
→ Hold dodge to ride the jellyfish for output
→ Assist / perfect dodge to extend Cadenza
→ Q to gather mobs and finish

3. Eidolons / Awakenings (A1-A8)

Level	Name	Effect	Priority
A1	Overture to the Future	Crit Rate +15% while in Cadenza	⭐⭐⭐
A2	A Special Song	A perfect dodge or Assist enters/extends Cadenza by 5 seconds, up to a max of 12 seconds	⭐⭐⭐⭐⭐ most crucial
A3	Rest of the Trio	Ultimate damage +20% while in Cadenza	⭐⭐⭐
A4	Blank Space on the Staff	DEF +20% when casting Staccato	⭐ no damage benefit, can skip
A5	An Ordinary Song	Ultimate Crit Rate +15%	⭐⭐
A6	Fugue of Days Past	Raises the Crescendo cap to 20 stacks, and grants 10 stacks immediately after casting Cadenza Aria	⭐⭐⭐⭐
A7	Resonant Harmony	Basic Attack, Shift, and Ultimate skill levels +1	⭐⭐
A8	Shared Melody	When entering / extending Cadenza, the whole team gains Psyche damage +8% for 15 seconds	⭐⭐

A0 playability: fully usable. At 0 Eidolons with the signature Arc Stellar Veil she can handle the Main DPS job in the 1.0 version. The recommendation is to unlock A2 (Cadenza uptime) and A6 (stack cap) first.

4. Best Gear

Arc Selection

Rank	Name	Source	Stats & passive
Theoretical best	Ready-Ready	Gacha (Nanally’s signature)	Base ATK 570, sub-stat Crit Rate 24% — Aurelia benefits from it too
⭐ F2P first choice	Stellar Veil	Free from Day 10 of the 14-day login	Base ATK 33→512 (max level), sub-stat ATK 27.5%. Core passive “Mercury”: Psyche anomaly damage +12%; each time you deal Psyche damage, Crit DMG +2% for 5 seconds, up to 10 stacks (+20%), can trigger every 0.1 seconds
Alternative	Fluff of Fortitude	Gacha	Unconditional damage bonus
Alternative	Ola Ora!	Gacha	Basic Attack stacking

Gear: Devil’s Blood: Curse 4-Piece

Pieces	Effect
2-piece	Psyche anomaly damage +10%
4-piece	Damage dealt +18%; when attacking a target affected by Nova or Stain, the damage bonus is doubled to +36%

Stat Priority

Slot	Priority
Main stat	Crit Rate → ATK% → Psyche DMG% → Crit DMG
Sub-stat	Crit Rate > Crit DMG > ATK% > generic DMG% > flat ATK

5. Recommended Teams

1. Nova Golden Team ⭐

Aurelia + Daffodill + Haniel + Fadia

Triggers the Nova reaction (Chaos + Psyche) to amplify the Curse set’s 36% bonus

2. Stain Team

Hathor + Skia + Aurelia + Fadia

Psyche + Lakshana triggers the Stain reaction, detonating the set bonus

3. F2P Lineup 1

Aurelia + Sakiri + Haniel + Mint

An all-free character combo

4. F2P Lineup 2 (Protagonist Team)

Aurelia + Skia + Esper Zero + Adler

Adler provides shields + DEF reduction

5. Top Setup (1.0 theoretical-best Aurelia team)

Aurelia + Daffodill + Hathor + Haniel

6. Build Priority

1. Ascend character level to 70 (main-story requirement), push to 80 if you have the resources
2. Skill leveling order: Basic Attack ≥ Ultimate > Assist > Shift (E)
   • Basic Attack contributes 70-80% of output, so leveling it first is never wrong
   • The Shift skill has the lowest marginal value and can go last
3. Max-level the Stellar Veil Arc (a free S-rank — no reason not to invest)
4. Devil’s Blood: Curse 4-piece: first gather loose pieces with the correct main stats, then slowly re-roll sub-stats
5. Awakening unlock priority: A2 > A6 > A1 > A3

7. Pull Advice

✅ No Need to Pull at All!

Aurelia is a free character auto-gifted on Day 3 of the 1.0 launch login, with her signature Arc Stellar Veil gifted on Day 10.

Just log in for 10 days and you’ll own:

• ⭐ 1 A-rank Main DPS character
• ⭐ 1 S-rank signature Arc

This is the highest value-for-effort free combo of the entire launch period, and you don’t even need to spend Crystals on the standard banner.

8. Community Memes / Reception

• “A free A-rank used as a Main DPS” — the highest damage ceiling among 1.0 A-rank characters, and getting her signature Arc for free puts her output at a near-S-rank level
• “Double free: login-gifted character + S-rank Arc” — an unprecedented free set, the best opening Main DPS for newcomers
• “The textbook free Main DPS” — Aurelia + Stellar Veil is the poster combo for “graduating without spending money”, called by the Chinese-language community “a gift to F2P players”
• “Legal jellyfish commuting” — an in-game detail meme, where Aurelia established the fun precedent for Hezero that “riding a jellyfish doesn’t count as a violation”
• Bahamut reception: some players note that “A-rank damage isn’t enough, only pull for love”, but the mainstream view is that Stellar Veil + the Curse 4-piece is enough to clear the 1.0 main story, making her a must-build for F2P players
