How the kit works
Once Lily arrives, build Dream Perfume by hitting enemies with Basic Attacks or casting Dream Blend. The skill restores 130 points and switches between Woven Fairytale (Heavy Attack) and Woven Phantasm (Heavy Attack). At 300 Dream Perfume, hold Normal Attack to use the selected mode.
During either mode, Lily pulls enemies, heals the team every second for 2 seconds and gains Dreambell Chime. At 300 Chime, press or hold Normal Attack for the corresponding finale. It also happens automatically when the mode ends. Switching early ends the mode, so let the finale resolve before switching.
The finale grants Sillage for 6 seconds. Use Blooming Fragrance during that window to give the team Silvered Dream and 25% All DMG Amplification for 30 seconds. Silvered Dream also increases interruption resistance and improves Echo Skill Crit. Rate and Crit. DMG.
Into the Dream Cradle starts Slumberland and Cradle Lullaby. Slumberland heals the nearby active Resonator every 3 seconds. While Cradle Lullaby is active, other teammates' Intro Skills build Dream Aroma, which increases team ATK. Lily's next Intro ends Slumberland and removes that buff, but restores Dream Perfume and helps her next Heavy Attack gain Chime.
Build and why
The game's build recommends five pieces of Flower of Tinged Yearning. Its supplied two-piece effect gives 10% Healing, which suits Lily's team healing. The five-piece effect is not included in the data, so do not plan around an assumed bonus. Rejuvenating Glow is an alternative with 10% Healing Bonus from two pieces.
Lullaby is the first weapon choice. Its Max HP increase and Concerto Energy on Liberation fit Lily's support kit. Healing with a Heavy Attack also enables its team effect: a Resonator who gains Unison or triggers Unison Response receives 16% ATK for 30 seconds while Soothed Soul is active. The supplied description of another effect is incomplete.
Cadenza is the next option, restoring 8 Concerto Energy on Resonance Skill once every 20 seconds. Static Mist follows, with 12.8% Energy Regen and an ATK increase for the incoming Resonator after Lily's Outro. Build Energy Regen: the finales gain critical bonuses above 100%, while the ATK bonuses from Silvered Dream and Dream Aroma scale above 190%.
Leveling priority
A suggested order is Dreamland of Flowers, Into the Dream Cradle, Dream Blend, Blooming Dream, then Mend and Cleanse. The Forte contains Lily's team healing and finales, while the Liberation provides sustained healing and the team ATK effect. The data does not say exactly how each effect changes with skill levels.
For maximum ascension, prepare 170,000 Shell Credit, 4 LF Exoswarm Core, 12 MF Exoswarm Core, 12 HF Exoswarm Core, 4 FF Exoswarm Core, 46 Suncoveter's Reach and 60 Reverie Lily.
For all skills, prepare another 2,030,000 Shell Credit, 25 LF Exoswarm Core, 28 MF Exoswarm Core, 40 HF Exoswarm Core, 57 FF Exoswarm Core, 26 Gold in Memory, 25 Incomplete Combustor, 28 Aftertune Combustor, 55 Remnant Combustor and 67 Reverb Combustor.
Resonance Chain nodes worth it
A suggested stopping point is Resonance Chain 2. Listen, a Requiem from the Dream Cradle (sequence 2) adds 2% Crit. Rate and 6% Crit. DMG per Dream Aroma stack while Cradle Lullaby is active. Dream Aroma can stack up to four times.
Look, White Flowers from the Ruins of Dreams (sequence 1) is required on the way and is useful on its own. It makes Lily immune to interruption during her woven attacks and finales, and lets each eligible teammate Intro grant two Dream Aroma stacks instead of one.
May Your Soul Wander No More (sequence 3) is worth considering for extra Dream Perfume, faster Dreambell Chime gain and extra energy. You can stop after sequence 2 or 3 if you do not need the later nodes: sequence 4 increases Slumberland healing, sequence 5 expands an Intro-triggered pull, and sequence 6 increases Lily's specified attack damage.
Teams
When Lily arrives, you can plan around her as the healer and buffer beside a damage dealer. Hsin, Suoming and Jinhsi are named teammate options. The available data does not establish which of them can trigger Unison Response, so check that condition rather than assuming it.
Lily's Outro gives the whole team 25% All DMG Amplification. For Silvered Dream's ATK bonus, the active Resonator must be able to trigger Unison Response, and the bonus counts up to four Unison Boon stacks on the team. Her Echo Skill critical bonuses and interruption resistance do not state that same condition.
During Cradle Lullaby, switch between other teammates to gain Dream Aroma through their Intro Skills. Each stack increases team ATK based on Lily's Energy Regen above 190%, up to 7% per stack and four stacks. Bringing Lily back removes Cradle Lullaby and Dream Aroma.
Common mistakes
Do not switch out during a woven Heavy Attack if you want its finale. Let it finish, then use the Outro while Sillage is still active. Sillage can trigger once every 20 seconds, so a second finale inside that interval will not provide it again.
Do not expect the Liberation's Shield to protect the next Resonator: it belongs to Lily and lasts 4 seconds. Switching during Slumberland keeps Lily on the field and preserves its healing, but stops Dreambind's attacks.
Do not ignore Energy Regen when planning her gear. Several buffs start scaling only above 190%. Also, do not count on the fatal-blow protection from Flowers for You for every rotation: it can trigger once every 5 minutes.
