Sparkle is a Quantum element character who follows the Path of Harmony. She is well known for her powerful DMG and Crit DMG boosts, especially thanks to her kit that increases the team’s Skill Point limit by 2. She is also an excellent choice for Skill Point–hungry teams, as she can restore 4 Skill Points simply by unleashing her Ultimate.
Best Cavern Relics
(2) Increases SPD by 6%.
(4) When using Skill or Ultimate on one ally target, increases the ability target's CRIT DMG by 18%, lasting for 2 turn(s). This effect can stack up to 2 time(s).

(2) Increases SPD by 6%.

(2) Increases Wind DMG by 10%.
(4) After the wearer uses their Ultimate, their action is Advanced Forward by 25%.

Best Planar Ornaments
(2) Increases the wearer's Effect RES by 10%. When the wearer's Effect RES is at 30% or higher, all allies' CRIT DMG increases by 10%.

(2) Increases the wearer's Energy Regeneration Rate by 5%. When the wearer's SPD reaches 120 or higher, the wearer's action is Advanced Forward by 40% immediately upon entering battle.
This set is particularly good for making Sparkle the first character to act at the start of the battle.
(2) Increases the wearer's Energy Regeneration Rate by 5%. If the wearer is not the first character in the team lineup, then increases the ATK of the first character in the team lineup by 12%.
Aside from the Energy Regeneration% it provides, this set also boosts the ATK% of the character in the first team slot. Note that this character should be your main DPS to maximize the effect.

info
It is essential to prioritize Crit DMG on Sparkle to maximize the Crit DMG buff she provides to her allies. She also needs high SPD so she can take frequent turns and spam her Skill. Equipping an Energy Regeneration Rate Rope is a must to help maintain her Ultimate uptime. For her Body and Sphere relics, HP% or DEF% main stats are recommended to improve her survivability when taking hits.
Best Light Cones
SourceLight Cone Event Warp
Capriciousness
Increases the wearer's CRIT DMG by 32~60%. At the start of the battle, the wearer gains Mask, lasting for 3 turn(s). While the wearer has Mask, the wearer's allies have their CRIT Rate increased by 10~14% and their CRIT DMG increased by 28~56%. For every 1 Skill Point the wearer recovers (including Skill Points that exceed the limit), they gain 1 stack of Radiant Flame. And when the wearer has 4 stacks of Radiant Flame, all the stacks are removed, and they gain Mask, lasting for 4 turn(s).This Light Cone fits perfectly as her signature, as Sparkle can maintain its Crit stat buffs simply by using her Ultimate each time it becomes available.
SourceStellar Warp, Light Cone Event Warp, Starlight Exchange, Stellar Convergence
Heir
Increases the wearer's Energy Regeneration Rate by 10~18% and regenerates 1 Skill Point when the wearer uses their Ultimate on an ally. This effect can be triggered once after every 2 uses of the wearer's Ultimate. When the wearer uses their Skill, the next ally taking action (except the wearer) deals 30~50% more DMG for 1 turn(s).This Light Cone is still good for Sparkle, as it helps manage her Ultimate uptime. However, the 1 Skill Point regeneration is somewhat underwhelming, since it can only be triggered after every two uses of her Ultimate. Additionally, the DMG buff granted to the next ally is hard to manage, as it requires your Main DPS to have lower SPD than Sparkle.
SourceLight Cone Event Warps
Departing Anew
After the wearer uses Skill or Ultimate on one ally character, the wearer regenerates 6.0~8.0 Energy and the ability's target receives 1 stack of "Hymn" for 3 turn(s), stacking up to 3 time(s). Each stack of "Hymn" increases its holder's DMG dealt by 15~24%. After every 2 instance(s) of Skill or Ultimate the wearer uses on one ally character, recovers 1 Skill Point.This Light Cone is less appealing, as the DMG buff it provides requires targeting a single ally with either a Skill or Ultimate. This puts Sparkle at a disadvantage, since only her Skill can target a specific ally, limiting the Light Cone’s effectiveness.
SourceStellar Warp, Departure Warp, Character Event Warp, Light Cone Event Warp
Cannot Stop It!
When the wearer uses their Ultimate, all allies' actions are Advanced Forward by 16~24%.This Light Cone may not provide any damage boosting, but it does grant an advance forward effect for the team, which is useful for stealing turns from enemies.
SourceStellar Warp, Departure Warp, Character Event Warp, Light Cone Event Warp
Departure
After entering battle, if an ally deals the same DMG Type as the wearer, DMG dealt increases by 12~24%.This Light Cone is only effective for Mono Quantum teams and offers little benefit outside of that setup.
