WHERE IT FITS

Characters and equipment that use this material

Quantum★★★★★

Sparkle

Released Feb 6, 2024Skill Point-supporting Harmony character with action advance and CRIT DMG buffsGuide

Sparkle supports an ally by advancing that ally’s action and scaling their CRIT DMG from her own CRIT DMG. Her Ultimate restores Skill Points and her Talent raises the party’s Skill Point maximum, making her worth considering for teams that use Skill Points frequently and can make good use of repeated ally turns. The input contains two distinct ability descriptions for her, so the article describes the shared effects and avoids treating the alternate wording as additional effects to purchase.

Physical★★★★★

Robin

Released May 8, 2024Physical Harmony support who advances the team and adds damage during ConcertoGuide

Robin boosts all allies’ damage with her Skill, then uses her Ultimate to make teammates act immediately and enter Concerto. While Concerto lasts, she raises allied ATK and adds a fixed-crit Physical hit after each ally attack, but Robin herself cannot take turns or act until the state ends. Consider her when the team can make use of the coordinated action window and frequent allied attacks.

Imaginary★★★★★

Sunday

Released Dec 4, 2024Harmony support that advances an ally and their summon while supplying CRIT buffs and EnergyGuide

Sunday boosts one ally’s damage and CRIT Rate, lets that ally and its summon act immediately, and uses his Ultimate to restore Energy and grant a CRIT DMG buff. Consider him for a damage dealer with a summon or for a non-Harmony ally who benefits from repeated action access. His Skill’s immediate action effect does not work on Harmony characters.

Quantum★★★★★

Tribbie

Released Feb 26, 2025Quantum Harmony support with teamwide damage amplificationGuide

Tribbie supplies teamwide All-Type RES PEN while her Skill state is active, raises enemies' damage taken with her Ultimate Zone, and adds attacks when allies use Ultimates. Consider her when a team benefits from broad damage amplification and can make use of her Zone's hit-count-based additional damage.

Wind★★★★★

Cerydra

Released Sep 2, 2025Wind Harmony support who advances one ally from Military Merit to PeerageGuide

Cerydra focuses her support on one ally. Military Merit raises that ally’s ATK; Peerage adds Skill damage CRIT DMG and All-Type RES PEN and enables Coup de Main when the ally uses Skill on an enemy.

Imaginary★★★★★

Trailblazer (Harmony · Caelus)

Released May 8, 2024Imaginary Harmony Break supportGuide

Trailblazer (Harmony · Caelus) grants all allies Break Effect and lets their attacks convert Toughness Reduction into Super Break DMG against Weakness Broken enemies. Consider this form when the team can break enemies and continue attacking during their broken state.

Imaginary★★★★★

Trailblazer (Harmony · Stelle)

Released May 8, 2024Imaginary Harmony Break supportGuide

Trailblazer (Harmony · Stelle) provides the same listed Harmony kit as the Caelus form: team Break Effect, Super Break conversion against Weakness Broken enemies, and Energy from Weakness Breaks. Consider this form when the party can attack broken enemies during the Ultimate’s support window.

Harmony★★★★

Dreamville Adventure

Introduced in v2.0Harmony Light ConeGuide

Dreamville Adventure boosts the damage of the ability type the wearer most recently used for the whole party. Consider it when your Harmony wearer regularly uses the same kind of ability as the damage your allies rely on.

Harmony★★★★

Poised to Bloom

Introduced in v2.4Harmony ATK and shared-Path CRIT DMG Light ConeGuide

Poised to Bloom increases the wearer’s ATK and, at battle entry, grants CRIT DMG to characters when at least two characters share a Path. Consider it when the wearer and another character meet that Path condition and can benefit from the buff.

Harmony★★★★

In Pursuit of the Wind

Introduced in v3.4Harmony Light Cone for support characters whose team benefits from increased Break DMG.Guide

In Pursuit of the Wind grants all allies increased Break DMG after entering combat. Consider it when Break DMG is relevant to your party; the effect is teamwide, but it does not state a bonus to other damage types.

Harmony★★★★

For Tomorrow's Journey

Introduced in v2.2Harmony personal damage Light ConeGuide

For Tomorrow’s Journey raises the wearer’s ATK and increases their damage dealt for one turn after they use their Ultimate. Consider it when the Harmony wearer’s own damage matters and Ultimate timing allows them to use the short bonus window.

Harmony★★★★

The Forever Victual

Introduced in v3.5Harmony ATK Light ConeGuide

The Forever Victual grants the wearer ATK and builds additional ATK when they use Skills, up to three stacks. Consider it for a Harmony wearer whose personal output benefits from ATK and who uses Skills often enough to build the passive.

Harmony★★★★★

Earthly Escapade

Introduced in v2.0Harmony CRIT support Light Cone tied to Skill Point recoveryGuide

Earthly Escapade gives the wearer CRIT DMG and temporarily boosts teammates' CRIT Rate and CRIT DMG through Mask. Recovering Skill Points builds Radiant Flame, which refreshes Mask after 4 stacks. Consider it when the wearer can recover Skill Points often enough to renew the team bonus.

Harmony★★★★★

Flowing Nightglow

Introduced in v2.2Harmony Light Cone that cycles from energy regeneration to a team damage buffGuide

Flowing Nightglow builds Energy Regeneration Rate as allies attack, then trades those stacks for a one-turn team damage buff when the wearer uses their Ultimate. Consider it when the party attacks often enough to build Cantillation and the wearer can use their Ultimate to activate Cadenza.

Harmony★★★★★

A Grounded Ascent

Introduced in v2.7Harmony Light Cone for ally-targeted damage stacks, Energy, and periodic Skill Point recoveryGuide

A Grounded Ascent gives the wearer Energy and buffs the ally targeted by their Skill or Ultimate. After every two such ally-targeted uses, it restores a Skill Point. Consider it for a Harmony wearer who regularly targets one ally with these abilities and can build the ally’s Hymn stacks.

Harmony★★★★★

If Time Were a Flower

Introduced in v3.1Follow-Up-triggered Harmony support Light ConeGuide

If Time Were a Flower grants the wearer CRIT DMG and gives the whole team CRIT DMG while Presage is active. The wearer gains Energy and Presage on entering battle, and further Energy and Presage after launching a Follow-Up ATK. Consider it for a Harmony wearer that can trigger Follow-Up ATKs often enough to refresh the team buff.

Harmony★★★★★

Epoch Etched in Golden Blood

Introduced in v3.5Harmony Light Cone that supplies an ally Skill DMG buff and conditional Skill Point recovery.Guide

Epoch Etched in Golden Blood gives its Harmony wearer ATK, restores a Skill Point after an Ultimate used to attack, and buffs an ally’s Skill damage after the wearer uses Skill on that ally. Consider it when the wearer can use that ally-targeting Skill and the team benefits from Skill Point recovery and Skill-focused damage.
