Sunday
Yes for summon/hypercarry—Sunday’s Skill Advance + CRIT buffs stay elite. Ultimate “Ode to Caress and Cicatrix” refunds a meaningful chunk of Energy inside the Skill. Best with Aglaea / Jing Yuan / The Herta / Phainon / Mydei. Energy LC helps; Ultimate Energy is wasted on non-Energy DPS (Feixiao/Acheron). Skip when your DPS can’t use single-target Advance cleanly.
Sunday is a 5★ Imaginary Harmony Support. Skill “Benison of Paper and Rites” is the primary in-combat spend. Ultimate “Ode to Caress and Cicatrix” is the payoff window for damage or team utility. This Phase 1 page covers kit text, gear targets, and pull notes—team comps stay empty until Phase 2.

Strengths
- Ultimate “Ode to Caress and Cicatrix” refunds a meaningful chunk of Energy inside the Skill—time it for the carry’s damage window instead of casting on cooldown out of habit.
- “Benison of Paper and Rites” action-advances an ally with a damage amp attached—one Skill Point buys a full extra carry turn.
- Sunday’s memosprite/summon adds a second actor that hits and breaks without always spending the team’s Skill Points.
- Talent “The Sorrowing Body” buffs allies’ damage for a short window—ignore it and Sunday plays like a worse generic Harmony unit.
Weaknesses
- Buff windows on “Ode to Caress and Cicatrix” are short—casting them when the carry cannot attack wastes the CRIT DMG/ATK amp for a full cycle.
- Sunday’s Skill is often the expensive part of the rotation; SP-negative teams force Basic ATKs and you lose the advance/amp that made the unit worth playing.
- Spamming “Benison of Paper and Rites” every turn without watching Skill Points strands the rest of the team—Sunday is often the SP sink.
- If “Ode to Caress and Cicatrix” is still offline at the end of a MoC cycle, the build is usually Energy/ERR or rotation order—not a missing CRIT roll.
Trace Priority
Benison of Paper and Rites carries most of the kit’s damage or utility—level this first.
Ode to Caress and Cicatrix supports the main rotation—raise after the top priority traces.
The Sorrowing Body supports the main rotation—raise after the top priority traces.
Gleaming Admonition is last priority outside of filling trace materials.
Stat Priority
Open with Technique if it helps, spend Skill to advance the kit’s resource, and hold Ultimate for the damage or buff window. Exact teammate order lands in Phase 2.
Open supports first, then spend the carry’s Skill/Ult inside the buff window. Exact order varies by the team tab above.
Light Cones
5★ · Path cone
After the wearer uses Skill or Ultimate on one ally character, the wearer regenerates #1[f1] Energy and the ability's target receives 1 stack of "Hymn" for 3 turn(s), stacking up to 3 time(s). Each stack of "Hymn" increases its holder's DMG dealt by 0.15%. After every 2 instance(s) of Skill or Ultimate the wearer uses on one ally character, recovers 1 Skill Point.
Why it works —Signature / best-in-slot when owned—passive lines up with Sunday’s kit triggers.
5★ · Path cone
Increases the wearer's Energy Regeneration Rate by 0.1% and regenerates 1 Skill Point when the wearer uses their Ultimate on an ally. This effect can be triggered once after every 2 uses of the wearer's Ultimate. When the wearer uses their Skill, the next ally taking action (except the wearer) deals 0.3% more DMG for 1 turn(s).
Why it works —Flexible alternative on the same path—equip if you already own it at higher superimposition.
4★ · Path cone
At the start of the battle and whenever the wearer's turn begins, one of the following effects is applied randomly: All allies' ATK increases by 0.1%, all allies' CRIT DMG increases by 0.12%, or all allies' Energy Regeneration Rate increases by 0.06%. The applied effect cannot be identical to the last effect applied, and will replace the previous effect. The applied effect will be removed when the wearer has been knocked down. Effects of the same type cannot be stacked.
Why it works —Best accessible option for most accounts—raise superimposition when copies drop.
4★ · Path cone
When the wearer uses their Skill, the next ally taking action (except the wearer) deals 0.16% increased DMG for 1 turn(s).
Why it works —Budget path cone—fine while building the account.
Relics
Team Compositions
Sunday enabling Archer. Archer, Sparkle, Fu Xuan complete the hypercarry shell.
Archer is the damage seat in this shell — build the supports around their rotation, not the reverse.
Enabler / amp piece this page is built around — keep their buffs or debuffs online every cycle.
Sparkle is the Advance / DMG amp — time their Skill/Ult for the carry’s damage window.
Fu Xuan shields the hypercarry and softens MoC / AS chip so glass DPS can commit to Skill spam.
Traces & Eidolons
Traces

Is it worth getting?
Comfort opener: Adds DEF ignore or shred on the enhanced hit. Nice QoL/damage, but E0 still runs the full kit—don’t break pity for E1 alone.
After the first use of Ultimate, recovers 2 Skill Point(s). The DMG dealt by "The Beatified" increases by 30%.
Is it worth getting?
Kit add-on: After the first use of Ultimate, recovers 2 Skill Point(s). Evaluate against your supports—pull only if that specific clause solves a problem you actually hit.
Ultimate Lv. +2, up to a maximum of Lv. 15. Basic ATK Lv. +1, up to a maximum of Lv. 10.
Is it worth getting?
Ultimate + Basic ATK levels only (+2). Free if you roll into it; never spend currency aiming for E3.
When the turn starts, regenerates 8 Energy.
Is it worth getting?
Side-grade: Refunds Energy when the listed trigger fires. Happy if it drops; not a planned stopping point.
Skill Lv. +2, up to a maximum of Lv. 15. Talent Lv. +2, up to a maximum of Lv. 15.
Is it worth getting?
Skill + Talent levels only (+2). Skip as a goal—grab it if you overshoot toward E6, never hard-pity for it.
The Talent's CRIT Rate boost effect becomes stackable up to 3 time(s), and the Talent's duration increases by 1 turn(s). When Sunday uses Ultimate, can also apply the Talent's CRIT Rate boost effect to the target. When the Talent's CRIT Rate boost takes effect and the target's CRIT Rate exceeds 100%, every 1% of excess CRIT Rate increases CRIT DMG by 2%.
Is it worth getting?
Whale ceiling: Flat combat-stat bump tied to a specific trigger. Only chase if Sunday is your dedicated Harmony main and E0–E2 already feel finished.
Sunday is fully usable at E0. Dedicated mains often stop at E0 before chasing higher. First stop: E0. Endgame target: E0.
