Increases Resonance Energy and buffs the next character’s ATK; deals high total Havoc DMG and is top Sub-DPS choice for Moonlit Clouds, with the nightmare variant favoring Havoc Sub-DPS via Midnight Veil.

Best Rejuvenating Glow for HP-scaling supports; synergizes with Shorekeeper and can rapidly charge Concerto Energy by holding the echo button without stopping the Resonator’s actions.

Best coordinated-attack Sub-DPS echo; provides ATK increase tied to critical hits from coordinated attacks and works off-field via blade summons.

Strong attacker when summoned; grants ATK buff for 15s after skill, deals up to 270% damage, and can be used in overworld for fast traversal.

Deals a total of 270% damage per summon and can be charged up to three times for multiple echo uses.

One of the two best Electro-DPS echoes; choose based on whether your Resonator scales off Resonance Skill, and it also supports coordinated-attack Sub-DPS via Empyrean Anthem sonata effects.

One of the two best Electro-DPS echoes; use when your Resonator scales off Resonance Liberation (Electro DPS matchup).

Top Wind/Aero-oriented reminiscence choice for Aero units; provides Aero DMG bonus (extra value for Aero Rover), helps Cartethyia’s Erosion DPS, and may offer a small time-slowing window.

Primary Aero Crown of Valor echo; can group enemies and is summon-type so it won’t interrupt combos.

Solid Spectro damage and useful in Spectro Resonator setups (DPS/Sub-DPS); grants 10% All-Attribute DMG Bonus to the next Resonator’s Intro Skill.

Good for passive Glacio DMG and coordinated-attack buffs; deals 270%+ Glacio DMG but is generally less universal than Hecate due to coordinated-attack scaling restrictions.

Main echo for Zani and Phoebe Spectro Frazzle builds; better than Nightmare: Mourning Aix because it can unconditionally provide Heavy Attack DMG, though it’s harder to farm (3-cost).

Strong passive for Aero units scaling off Echo Skill DMG; summon-type so it blends into rotations and deals quick Aero damage on cast.

Provides Spectro and Basic Attack DMG simply by being equipped as main Echo, and has unique utility from using both Twin Nova echoes together.

More inflexible because it targets Sub-DPS in Havoc teams; nightmare version gives 300%+ total Havoc DMG, while normal variants can be better outside Havoc.

Rated as strong due to its Glacio/coordinate synergy (nightmare flavor), though its value depends on whether your Coordinated Attacks scale with Glacio DMG Bonus.

Niche echo usable only by Lupa; valuable as a 4-cost in Flaming Clawprint but otherwise largely wasted—farm only if building Lupa.

Best echo for the Frosty Resolve sonata effect; deals lots of echo damage and doesn’t need to be summoned to grant its bonuses.

Slightly tailored to Augusta with Electro DMG + Heavy Attack DMG bonuses; high-value because it’s the only 4-cost in Crown of Valor and provides stats without needing Echo Skill activation.

Primarily works as the second 4-cost echo for Cartethyia’s 44111 configuration; buffs are somewhat underwhelming (Glacio + Aero) and don’t provide a sonata benefit for Glacio characters despite buffing them.
