Wuthering Waves Lily Support Build: Echo Buffs, Weapons, and Rotations

To build Lily as an Echo-focused support in Wuthering Waves, equip her with the 5-piece Moonlit Clouds set, prioritize Energy Regeneration until her Resonance Liberation triggers consistently every rotation, and use her rapid Concerto generation to pass buffs to your primary burst carry.

Core Kit and Echo Buffing Mechanics

Lily provides targeted amplification for summoned and transformed Echo skills rather than standard stat boosts. Her kit centers on three mechanics:

• Resonance Skill: Deploys a persistent field that continuously increases the damage of party Echo skills while generating Concerto Energy.
• Forte Circuit: Basic attacks and skills accumulate musical charges. Consuming a full gauge with a Heavy Attack enters Lily into a resonant performance state, granting the entire team bonus Echo skill damage and critical strike stats for a brief window.
• Outro Skill: Transfers a direct Echo skill amplification buff to the incoming Resonator upon swapping out.

Because her Outro buff and active field linger on the battlefield, you must swap into your main damage dealer immediately after her Heavy Attack and Echo cast to align their burst skills with these active windows.

Lily vs. Shorekeeper Support Comparison

Lily and Shorekeeper fill different support roles depending on whether your team relies on frontloaded Echo bursts or sustained broad-stat carry windows:

Lily excels in dual-core setups where rapid Concerto generation cuts down rotational downtime, allowing burst carries to cycle through Tower of Adversity stages faster.

Echo Sonata and Stat Priorities

Lily requires sufficient Energy Regeneration to ensure her Resonance Liberation is ready every time she takes the field.

• Sonata Effect: Moonlit Clouds (5-Piece) is her primary set. It grants an attack buff to the incoming Resonator when Lily triggers an Outro Skill, stacking directly with her Echo amplification. If another team member already holds this set, use an alternative utility or energy sonata to avoid duplicate set overlap.
• 4-Cost Primary Echo: Impermanence Heron provides extra teamwide damage amplification when cast right before triggering an Outro Skill.
• 3-Cost Echoes: Run Energy Regeneration on both 3-cost slots until rotation thresholds are met.
• 4-Cost Main Stat: Run Critical Rate or ATK% to maintain off-field damage contribution.
• Sub-Stat Priority: Energy Regeneration > Critical Rate / Critical DMG > ATK%.

Weapon Selection

Lily requires weapons that grant Energy Regeneration or bonus Concerto generation to prevent rotation delays.

• Signature Weapon: Provides an immediate burst of energy upon casting a skill, alongside an aura that passively boosts party Echo damage.
• Four-Star Energy Alternatives: Any weapon featuring an Energy Regeneration secondary stat lowers the burden on Echo sub-stats. Weapons that grant bonus Concerto Energy on hit or skill execution allow Lily to execute her entire sequence and trigger an Outro Skill in a single attack string.
• Weapons to Avoid: Pure damage weapons lacking energy utility. Failing to charge her Outro Skill on cooldown negates her main advantage over general buffers.

Resonance Chain (Sequence) Investment

Lily functions as a complete support at S0. Extra copies provide targeted convenience or transition her into a secondary damage dealer:

• Sequence 1 (S1): Improves energy generation and adds interruption resistance during her Forte Heavy Attack, preventing bosses from canceling her performance state.
• Sequence 2 (S2): Increases the duration and stat values of her Outro Skill Echo buff, making it the most cost-effective stopping point for spenders pairing her with carries that have longer burst animations.
• Sequences 3 to 5 (S3–S5): Primarily raise personal damage multipliers without altering team support functions.
• Sequence 6 (S6): Grants high personal damage scaling during her resonant state, turning her into a hybrid burst-carry.

Rotation Sequence

Pair Lily with a dedicated carry who relies on high-multiplier Echo skills, alongside a standard healer or secondary buffer. Follow this five-step sequence during combat:

1. Opener: Trigger your healer or primary buffer's skills to set up initial shields, healing fields, or baseline attack buffs.
2. Lily Entry: Swap into Lily via Intro Skill and immediately cast her Resonance Skill to drop her buff field.
3. Forte Discharge: Execute basic attack strings until her musical gauge is full, then cast a Heavy Attack to enter the resonant state and activate her Resonance Liberation.
4. Echo and Outro: Activate Impermanence Heron to lock in the Moonlit Clouds bonus, then immediately trigger her Outro Skill.
5. Carry Burst: Swap to your primary DPS, instantly unleash their main Echo skill inside Lily's overlapping field, and execute their full burst combo.
