Sparkle / Qingque / Trailblazer (Ice) / Lynx
A Sparkle-centered Skill-Point consumption team. Use Qingque as the main DPS (F2P-friendly) to take full advantage of Sparkle's ATK buffs and the damage from consuming Skill Points. Lynx provides AoE healing and debuff clear; Trailblazer (Ice) fills the remaining support slot.
Sparkle / Archer / Cipher / Gallagher
A Sparkle team focused on an Archer-style DPS with Cipher as sub-DPS and Gallagher for sustain. This comp can be adapted into a Mono-Quantum team; if the enemy lacks Quantum weakness, consider bringing Silver Wolf to apply it.
Sparkle / Imbibitor Lunae / Tingyun / Luocha
A Skill-Point feeding comp built around Imbibitor Lunae as the main damage dealer. Sparkle supplies party ATK and other buffs while Tingyun restores Imbibitor's energy so he can use his Ultimate more often. Luocha offers reliable healing without consuming Skill Points. Many DPS options can replace Imbibitor depending on playstyle and Eidolons.
