How the kit works
Start with EX Special Attack: Ode to Dawn (Special) when you have enough Energy. It deals Lumiflux DMG and applies 2 Lumiflux Buildup to enemies hit. On entering the battlefield, Remielle also recovers to 60 Energy if she has less; in Investigation Zone Mode, that recovery can trigger once every 180 seconds.
Hold Basic Attack: Solo Dance to gain Floating Radiance when it hits. The fourth hit of Basic Attack: Leap applies 1 Lumiflux Buildup. Once Floating Radiance reaches 120, hold after a Special Attack or EX Special Attack to enter Stance Shift, then switch characters to enter Phase Flow. Against a Stunned enemy, a hit from either Special at full Floating Radiance also lets you switch directly into Phase Flow during the attack.
In Phase Flow, Remielle attacks on her own while Floating Radiance drains. You cannot normally switch her back in until she exits, unless you use a Chain Attack. Triggering three reactions during one Phase Flow unlocks her normal switch-in and Assist: Flower & Feather Dance. That Assist extends a hit enemy's Stun by 3 seconds, once per Stun window, and enters Luminous Reflection. It costs no Floating Radiance if she has 90 or less when it activates.
Reactions Remielle triggers through a teammate generate Voidflare; she can store the three most recent. With Voidflare stored, hold Basic Attack: Rainbow's End to attack and consume it. In Luminous Reflection, that attack becomes Basic Attack: Fleeting Grace. Either triggers Luminize on a hit, dealing Attribute Anomaly DMG based on the stored Voidflares. Chain Attack: Interwoven Dance Steps also enters Luminous Reflection. The Assist and Ultimate: Dazzling Curtain Call can trigger Luminize on a hit too.
Build and why
Use four pieces of Feathered Fate and two pieces of Freedom Blues. Feathered Fate gives Anomaly Proficiency and, after Remielle enters or switches in, another 50 Anomaly Proficiency plus 15% Attribute Anomaly DMG for 15 seconds. The buff stays active off-field, which suits Phase Flow. Freedom Blues adds another 30 Anomaly Proficiency from its two-piece bonus. Two pieces of Chaos Jazz offer the same stat as an alternative.
Anomaly Proficiency suits her core passive: it increases her Refringe Coefficient and the Luminize multiplier. Put Anomaly Proficiency on disc 4 and Percent ATK on discs 5 and 6. For substats, follow the game's order: Percent ATK, Anomaly Proficiency, then ATK. Her squad ATK increase also scales with her initial ATK.
Ode of Resurrected Wings is the first weapon choice. It gives 96 Anomaly Proficiency; a Refringe reaction grants the equipper 20% Anomaly DMG and the squad 30% DMG for 30 seconds. Weeping Gemini is next: squad Attribute Anomalies build up to four Anomaly Proficiency stacks, though they expire when the target recovers from Stun or is defeated. Flamemaker Shaker is another option, with off-field Energy Regen and Anomaly Proficiency once its damage buff reaches five stacks.
Leveling priority
Follow the game's skill order: Core Passive: Temporal Patterns = Stilled Colors first, then Chain Attack: Interwoven Dance Steps, Basic Attack: Leap, Quick Assist: Featherglow Rebirth, Special Attack: Sliver of Light, and Dodge: Retreating Light. The core passive governs Voidflare and Luminize; the next priorities cover attacks used to enter Luminous Reflection and spend stored Voidflare.
For maximum ascension, you need 800,000 Denny, 4 Basic Anomaly Certification Seal, 32 Advanced Anomaly Certification Seal and 30 Controller Certification Seal. For all skills, the listed total is 2,905,000 Denny, 25 Basic Lumiflux Chip, 75 Advanced Lumiflux Chip, 250 Specialized Lumiflux Chip, 5 Hamster Cage Pass, 9 Timeworn Husk and 60 Higher Dimensional Data: Deep Erosion Circuit.
Mindscapes worth it
A suggested progression priority is Fall Into the Noise, Naive Oath, then Lone Feather's Endless Flight. M2 adds 20% Refringe Coefficient and lets Anomaly damage from Anomaly characters ignore 15% DEF against enemies affected by Prismatic. That DEF effect lasts another 8 seconds after Prismatic ends. M2 also makes Remielle apply Lumiflux Buildup more often through automatic attacks in Phase Flow.
M1 gives 200 Decibels when she uses Assist: Flower & Feather Dance, once every 18 seconds. M6 gives three special Voidflares after the fourth Basic Attack hit lands; their damage is 25% of the special Voidflares gained on entering the battlefield. The Garden of Diverging Time and To Drink Forgetfulness only raise skill levels, so they are reasonable upgrades to skip if you are choosing which effects to prioritize.
Teams
With the additional ability active, three Anomaly characters give the squad an ATK increase equal to 40% of Remielle's initial ATK, capped at 1,600. Her Prismatic effect gives attacks against affected enemies 15% increased Anomaly Buildup Rate. The increase persists for 8 seconds after Prismatic is removed.
Common mistakes
Do not switch out immediately after entering Stance Shift unless you have the next character ready to use the field time. During Phase Flow, Remielle cannot normally return until the state ends or her switch-in is unlocked. If you do not switch after Stance Shift, she attacks downward and returns to the ground instead.
Do not spend stored Voidflare without checking whether Luminous Reflection is available. Chain Attack and her special Assist can give her the upgraded held Basic Attack. Against a Stunned enemy, landing the Assist also gives the team more time to attack.
Do not ignore ATK while chasing Anomaly Proficiency. Both matter to her build, and the game's recommended substats put Percent ATK first. Also remember that Feathered Fate's four-piece buff has a 15-second duration, even though it remains active off-field.
