Sparkle — Qingque / Trailblazer (Ice) / Lynx
A simple Mono-Quantum Sparkle comp using free-to-play options. Use Qingque and Lynx to take advantage of Sparkle's Bonus Ability that boosts all Quantum units' ATK. Qingque is the recommended F2P DPS since she scales well when consuming Skill Points.
Sparkle — Archer / Cipher / Gallagher
Mono-Quantum Sparkle team that fully utilizes Sparkle's kit. If the enemy lacks a Quantum weakness, consider bringing a unit like Silver Wolf (not listed in core) to apply the missing Quantum weakness so your Quantum DPS can benefit fully.
Sparkle — Imbibitor Lunae / Tingyun / Luocha
Sparkle + Imbibitor Lunae centered comp: feed Imbibitor Skill Points for massive damage. Tingyun helps by restoring energy so Imbibitor can Ultimate more often; Luocha provides sustain without needing Skill-Point consumption.
