Core goal: Stack as much Anomaly Proficiency as possible so Vivian's off-field Abloom, Corruption, and Disorder hits actually hurt. She lives off-field and triggers extra attacks when teammates use EX Specials. The build exists to make those procs scale hard.

1W-Engine Choice

Flight of Fancy (Signature) Best

Big AP substat plus 40 percent Anomaly Buildup Rate plus stacking AP every time she deals Ether damage (up to 6 stacks). Players treat this as a large upgrade but not mandatory.

Weeping Gemini R5 Best F2P

Stacks large AP every time anyone on the team applies an Attribute Anomaly. This matches her playstyle perfectly because she stays off-field while Jane, Alice, Yuzuha, Yanagi, etc. apply anomalies. Multiple players run it on both Vivian and another anomaly unit in the same team with no issue.

Electro-Lip Gloss or Rainforest Gourmet Filler

Acceptable fillers if you don't have Gemini yet.

Decision point: Don't pull the signature unless you already have the characters you need. Community consensus is Weeping Gemini is good enough, save pulls. If you already own Flight of Fancy, keep it on her.

2Drive Disc Sets

24pc Phaethon's Melody plus 2pc Chaos Jazz or Freedom Blues
  • 1
    Phaethon's Melody 2pc: plus 8 percent Anomaly Mastery.
  • 2
    Phaethon's Melody 4pc: When any teammate uses an EX Special, Vivian gets plus 45 AP for 8s.

    If it wasn't her own EX, she also gets plus 25 percent Ether DMG. This lines up with how her kit works.

  • 3
    Chaos Jazz or Freedom Blues 2pc: plus 30 Anomaly Proficiency.
Don't settle for mixed 2pc plus 2pc plus 2pc. The 4pc is the point. Farm the Phaethon set in the relevant Combat Simulation stage.

3Main Stats and Substats

SlotStat
Disc 4Anomaly Proficiency (mandatory)
Disc 5Ether DMG percent first, then PEN Ratio or ATK percent
Disc 6Anomaly Mastery (do not default to Energy Regen unless you are constantly starving for Flight Feathers)
SubsAnomaly Proficiency, then ATK percent, then Flat ATK or PEN
3Good Enough Finished Numbers
  • 1
    With signature: around 2500 ATK and 450 or more AP.
  • 2
    With Weeping Gemini: around 2600 to 2650 ATK and around 360 AP on the stat screen.

    The engine stacks extra AP in combat.

Level discs to 15. A mediocre S-rank disc is still better than a purple one.

4Practical Farming and Upgrade Order

  • 1
    Get Weeping Gemini (or her signature) and level it.
  • 2
    Farm 4pc Phaethon's Melody until you have usable main stats on 4, 5, and 6.
  • 3
    Then chase AP substats on Disc 1 to 3.
  • 4
    Only then worry about perfect rolls.
Players repeatedly say stop using Tuning Calibrators on anomaly characters except in rare cases. Just keep farming raw pieces.
