Should You Pull?YES

Yes for Spectro Frazzle / Prayer carry—Phoebe’s Absolution window is the kit. Liberation “Dawn of Enlightenment” deals a focused attribute damage hit as the named setup tool. Best with Zani / Shorekeeper / Verina. Full Prayer into Absolution/Confession wants clean Forte routing—half stacks waste the Liberation. Skip when you won’t build Spectro Frazzle teams and already cover Spectro damage.

Phoebe is a 5★ Spectro Main DPS who fights with a Rectifier. Liberation “Dawn of Enlightenment” deals a focused attribute damage hit as the named setup tool. Forte “Radiant Invocation” spends full Prayer on Absolution / Confession Forte casts.

Strengths

  • Liberation “Dawn of Enlightenment” deals a focused attribute damage hit as the named setup tool — that window is where Phoebe’s clear speed actually shows up.
  • Forte “Radiant Invocation” spends full Prayer on Absolution / Confession Forte casts, so resource banking is mandatory, not optional filler.
  • Outro “Attentive Heart” hits every nearby target in one cast — swap timing is part of the damage plan, not just Concerto filling.
  • Aerial / plunge routes give flexible dodge and reposition options mid-combo.

Weaknesses

  • Field-time hungry once Liberation “Dawn of Enlightenment” is up — double-DPS swaps dilute the dump window.
  • Wants dedicated supports and ER planning; dropped into a random squad, Liberation uptime falls off a cliff.

Lynae

Rover (Spectro)

Rover (Spectro) shares field time with Phoebe — trade Intro / Outro so both Liberation windows get amp coverage.

Resonance SkillTo Where Light Shines

Summon a Ring of Mirrors at the target location, making the target hit stagnate for 2s and dealing Spectro DMG. The stagnation effect can be applied to 12 targets max for each Ring of Mirrors. Using Resonance Skill again shortly after the summoning teleports Phoebe to the Ring of Mirrors' location, dealing Spectro DMG. Unable to teleport if Phoebe is too far from the Ring of Mirrors. Ring of Mirrors - Ring of Mirrors lasts for 30s. When Phoebe summons a new Ring of Mirrors, the existing Ring of Mirrors disappears. - When Phoebe is outside of the Ring of Mirrors, a Basic Attack or Dodge Counter that hits the Ring of Mirrors will refract Holy Light, which deals Spectro DMG to targets inside the Ring of Mirrors and pulls the targets hit to the center of the ring. The DMG dealt is considered Basic Attack DMG. Can be triggered once every 0.5s. - When Phoebe is inside the Ring of Mirrors, Basic Attack becomes Basic Attack Chamuel's Star, which performs up to 3 consecutive attacks, dealing Spectro DMG, considered Basic Attack DMG.

Resonance LiberationDawn of Enlightenment

Phoebe concentrates the light in her hands into the Mirror of Enlightenment and smashes it, dealing Spectro DMG. - Absolution Enhancement: Increase DMG Multiplier by 255%. - Confession Enhancement: Apply 8 stacks of Spectro Frazzle to targets hit.

Tune BreakTune Break: Rectifier

When the target's Off-Tune Level is full, the Resonator may cast Tune Break on the target.

Forte CircuitRadiant Invocation

When Phoebe's Prayer is full, consume all Prayer to cast one of the following skills: - Hold Basic Attack to cast Heavy Attack Absolution Litany, dealing Spectro DMG and applying 1 stack of Spectro Frazzle to the targets hit. Phoebe enters Absolution status, which allows her to deal more damage. - Hold Resonance Skill to cast Resonance Skill Utter Confession, dealing Spectro DMG and applying 1 stack of Spectro Frazzle to the targets hit. Phoebe enters Confession status, which allows her to better exploit Spectro Frazzle. - Absolution and Confession cannot coexist. Entering into one will end the other. - When Divine Voice is not exhausted, Phoebe is unable to cast Heavy Attack Absolution Litany and Resonance Skill Utter Confession. - When Divine Voice is exhausted, Phoebe will not exit the Absolution or Confession status. Heavy Attack: Starflash When Phoebe has Divine Voice, casting Basic Attack Stage 3 or Dodge Counter replaces the next Heavy Attack with Heavy Attack: Starflash, which deals Spectro DMG at the cost of 30 Divine Voice. - Absolution Enhancement: Reduce the cost of Divine Voice by 15. When the targets hit have Spectro Frazzle, the skill gains 256% DMG Amplification. - Confession Enhancement: Apply 5 stacks of Spectro Frazzle to the targets hit.

S1Warm Light and Bedside Wishes

When in Absolution, Resonance Liberation Dawn of Enlightenment now increases DMG Multiplier by 480% instead of 255%. When in Confession, Resonance Liberation Dawn of Enlightenment increases DMG Multiplier by 90% and applies Spectro Frazzle to the targets with the maximum stack the targets can receive.

Is it worth getting?

Modest S1: Adds RES / DEF shred or a large DMG Bonus clause. Helpful padding, not a build-defining unlock.

S2A Boat Adrift in TearsPull Target

When in Absolution, DMG dealt by Outro Skills to targets with Spectro Frazzle is Amplified by 120%. When in Confession, Silent Prayer grants 120% more DMG Amplification for Spectro Frazzle.

Is it worth getting?

Stat-leaning S2: Extra Amplification on Liberation / attribute damage. Clear damage, but it does not rewrite Phoebe’s rotation the way a mechanic Sequence would.

S3Daisy Wreaths and Dreams

When in Absolution, the DMG Multiplier of Heavy Attack Starflash is increased by 91%. When in Confession, the DMG Multiplier of Heavy Attack Starflash is increased by 249%.

Is it worth getting?

Situational S3: When in Absolution, the DMG Multiplier of Heavy Attack Starflash is increased by 91%.

S4Ringing Bells on Wings Aloft

When Basic Attack, Basic Attack Chamuel's Star, Dodge Counter, or Chamuel's Star: Dodge Counter hits, the target's Spectro RES is reduced by 10% for 30s.

Is it worth getting?

Side-grade: Adds RES / DEF shred or a large DMG Bonus clause. Happy if it drops; not a planned stopping point.

S5Prayer to the Distant LightSkip

Casting Intro Skill Golden Grace increases Phoebe's Spectro DMG Bonus by 12% for 15s.

Is it worth getting?

Late luxury: Adds RES / DEF shred or a large DMG Bonus clause. Grab it if you overshoot toward S6 — never hard-pity for S5 alone.

S6Whispering Chirps in SilenceSkip

Targets entering the Ring of Mirrors are stagnated for an additional 2s. The stagnation effect affects all targets entering the Ring of Mirrors and can be applied to 12 targets max for each Ring of Mirrors. Each target will only be affected by this effect once. When in Absolution or Confession, summoning a Ring of Mirrors with Resonance Skill increases Phoebe's ATK by 10% for 20s, and triggers an extra Heavy Attack Starflash at the Ring of Mirrors' location. This Heavy Attack Starflash does not consume Divine Voice and is not considered as casting a Heavy Attack.

Is it worth getting?

Whale ceiling: Raises party ATK from a Stellarealm / team aura. Only chase if Phoebe is your dedicated main and S0–S2 already feel finished.

Phoebe is fully usable at S0. Most dedicated mains stop at S2 before chasing higher Wavebands. First stop: S2. Endgame target: S2.
