How the kit works
Start with To Where Light Shines to place a Ring of Mirrors at the target. It deals Spectro DMG and stagnates the target for 2 seconds. Recast the skill shortly afterwards to teleport to the ring, provided Phoebe is not too far away. The ring lasts 30 seconds, and placing another removes the old one.
Inside the ring, O Come Divine Light becomes the three-hit Chamuel's Star. From outside, a Basic Attack or Dodge Counter that hits the ring refracts light, damages targets inside and pulls those hit toward its center. This damage counts as Basic Attack DMG and can trigger once every 0.5 seconds.
Radiant Invocation gives Phoebe up to 120 Prayer, regenerating 5 per second. At full Prayer, hold Basic Attack for Absolution or hold Resonance Skill for Confession. Either choice restores 60 Divine Voice, but neither can be used while Divine Voice remains. The chosen status stays even after Divine Voice runs out.
With Divine Voice available, use the third Basic Attack or a Dodge Counter, then Heavy Attack for Starflash. In Absolution it costs 15 Divine Voice and gains 256% DMG Amplification against targets with Spectro Frazzle. In Confession it costs 30 and applies 5 stacks. Dawn of Enlightenment gains 255% DMG Multiplier in Absolution or applies 8 stacks in Confession.
When switching out, Attentive Heart deals Spectro DMG equal to 528.41% of Phoebe's ATK. In Confession it also reduces nearby targets' Spectro RES by 10% and grants 100% Spectro Frazzle DMG Amplification for 30 seconds, or until Phoebe enters Absolution. It extends the damage interval by 50% when Spectro Frazzle deals damage.
Build and why
Use the recommended five-piece Eternal Radiance. Its two-piece effect gives 10% Spectro DMG, which suits Phoebe's attacks. The five-piece effect is not described in the supplied game data, so do not assume an extra effect from it.
Luminous Hymn is the first weapon choice. It gives 12% ATK, rewards damage against targets with Spectro Frazzle with Basic Attack DMG Bonus and Heavy Attack DMG Bonus, and amplifies Spectro Frazzle DMG after an Outro Skill. Stringmaster comes next: its Attribute DMG Bonus and ATK effects are useful for damage. Cosmic Ripples follows, offering Energy Regen and a stacking Basic Attack DMG Bonus.
Ocean's Gift is another option when you can keep Spectro Frazzle on targets: hitting them builds Spectro DMG. ATK also matters to Phoebe's Outro, whose damage uses her ATK. No main-stat or substat selection is listed in the build.
Leveling priority
A good leveling order is Radiant Invocation, then Dawn of Enlightenment. Starflash is part of the Forte, while Liberation deals damage in either mode and applies Spectro Frazzle in Confession.
After those, consider O Come Divine Light, To Where Light Shines, then Golden Grace. Basic Attacks are part of Phoebe's field time, the skill places her ring, and the Intro deals Spectro DMG when she enters. This order is a suggestion, not a stated game recommendation.
For maximum ascension, you need 170,000 Shell Credit, 4 LF Whisperin Core, 12 MF Whisperin Core, 12 HF Whisperin Core, 4 FF Whisperin Core, 46 Cleansing Conch and 60 Firecracker Jewelweed. For all skills, you need 2,030,000 Shell Credit, 25 LF Whisperin Core, 28 MF Whisperin Core, 40 HF Whisperin Core, 57 FF Whisperin Core, 26 Sentinel's Dagger, 25 Lento Helix, 28 Adagio Helix, 55 Andante Helix and 67 Presto Helix.
Resonance Chain nodes worth it
Warm Light and Bedside Wishes (sequence 1) is a good first stopping point. In Absolution it raises Liberation's added DMG Multiplier from 255% to 480%. In Confession, Liberation gains 90% DMG Multiplier and applies the maximum number of Spectro Frazzle stacks the target can receive.
A Boat Adrift in Tears (sequence 2) is worth considering for either mode: it amplifies Outro Skill damage against targets with Spectro Frazzle in Absolution, or gives Silent Prayer 120% more Spectro Frazzle DMG Amplification in Confession. Whispering Chirps in Silence (sequence 6) adds an extra Starflash when the ring is summoned in either status, without consuming Divine Voice.
If you do not need those later effects, you can stop before Daisy Wreaths and Dreams (sequence 3), which increases Starflash's DMG Multiplier. Ringing Bells on Wings Aloft (sequence 4) offers a 10% Spectro RES reduction, while Prayer to the Distant Light (sequence 5) gives Phoebe Spectro DMG Bonus after her Intro. Reaching the sixth node requires the earlier nodes, so you cannot skip them on the way.
Teams
For a team built around Phoebe's own damage, consider keeping her on the field in Absolution and bringing teammates that cover the rest of the team's needs. For a Spectro Frazzle team, use Confession and switch out after building stacks. The available data does not describe the teammates' kits, so check their abilities before assigning healing or stack application to them.
Common mistakes
Do not try to enter a different status while Divine Voice remains. Spend it on Starflash first, then use full Prayer to make your next choice. Running out of Divine Voice does not remove your current status.
Do not switch to Absolution if you want to keep the Confession Outro effect: that ends it early. Also watch your position around the ring. Its Basic Attack behavior changes depending on whether Phoebe is inside or outside, and the skill's teleport fails if she is too far away.
