• Increases Resonance Energy of the equipping character and the ATK of the next character taking the field.
• The skill itself deals 300%+ total Havoc DMG.
• Still the best in slot for any Sub-DPS running Moonlit Clouds. The nightmare version of this echo only has the Midnight Veil sonata effect which is a bit more inclined for Havoc Sub-DPS's.

• The best Rejuvenating Glow echo for the best HP-scaling supports in the game.
• Works with Shorekeeper, the best healer in the game right now.
• Can charge Concerto Energy extremely fast by holding the echo button. Resonators can still act while Fallacy is delivering a flurry of punches.

• The best echo for Sub-DPS that does coordinated attack.
• ATK increase for the current resonator as long as the coordinated attacks deal critical hits.
• Echo effect summons blades that also works off-field.

• Extremely effective attacker when summoned in battle.
• ATK is increased for 15s after skill activation
• The skill deals up to 270% damage.
• Can be used in the overworld to traverse quickly.

• Deals a total of 270% damage everytime it is summoned.
• Skill can be charged up to three times, so you can use the echo skill multiple times.

• One of the two best echo for Electro DPS.
• See if your Resonator scales off Resonance Skill or Resonance Liberation. If Resonance Skill, use Tempest Mephis.
• Also has access to Empyrean Anthem sonata effects, so this echo could also work with coordinated attack Sub-DPS characters.

• One of the two best echo for Electro DPS.
• See if your Resonator scales off Resonance Skill or Resonance Liberation. If Resonance Liberation, use Thundering Mephis.

• Primary Gusts of Welkin and Windward Pilgrimage 4-cost echo.
• Grants Aero DMG Bonus to the wearer with bonus 10% if worn by Aero Rover.
• Can also be used by Ciaccona as the definitive Aero Erosion enabler.
• Definitive echo set for the Erosion DPS, Cartethyia.
• Seems to provide a small window of time-slowing effect when used, enabling you to deal damage freely.

• Primary Aero Crown of Valor 4-cost echo.
• Can group enemies with its echo skill, great for mobs of enemies.
• Echo Skill is summon-type, so it will not interrupt any combo.

• Deals decent Spectro DMG to enemies.
• Part of both Rite of Gilded Revelation and Pact of Neonlight Leap, which are good for Spectro Resonators, both DPS and Sub-DPS, respectively.
• Gives 10% All-Attribute DMG Bonus to Intro Skill of the next Resonator.

• Great for providing passive Glacio DMG Bonus and Coordinated Attack DMG buffs.
• The skill itself deals 270%+ Glacio DMG.
• Less useful than Hecate in most situations as not all resonators that deal Coordinated Attacks scale off Glacio DMG Bonus.

• The main echo for the two characters that uses Spectro Frazzle: Zani and Phoebe.
• The better option over Nightmare: Mourning Aix because it can also provide Heavy Attack DMG unconditionally.
• Pretty hard to farm because it's a 3-cost echo.

• Focuses mainly on Sub-DPS in Havoc teams, so it is a bit inflexible.
• The normal variants may be a bit more useful in non-Havoc team situations.
• The skill itself deals 300%+ total Havoc DMG.

• The best echo for those running the new Frosty Resolve sonata effect.
• Deals a lot of damage as an echo.
• Does not need to be summoned to provide echo bonuses.

• Slightly tailor-fitted to Augusta, since it gives both Electro DMG and Heavy Attack DMG Bonus.
• The only 4-cost Echo in Crown of Valor, making it a high value option.
• This Echo is a transform-type Echo, so you will be using some time to deal damage with it.
• The stat bonus doesn't require Echo Skill activation, so you automatically get it once equipped.

• A bit niche to use, since it can only be used by Lupa.
• Only 4-cost in Flaming Clawprint, so it is a bit valuable.
• Effect performs well with Lupa alone, but is a big waste on other units.
• Only farm if you are building Lupa!

• So far only works as the second 4-cost for the 44111 echo configuration of Cartethyia.
• Buffs are a bit underwhelming, as it buffs both Glacio and Aero DMG Bonuses.
• No sonata effect that benefits Glacio characters despite buffing them.

• Limited utility; serves as a basic DPS option but lacks notable advantages over other echoes.

• A specialized echo best suited for specific team compositions; overall not very versatile.

• Provides decent buffs but overshadowed by higher-ranking echoes with more unique effects.
