Sparkle is a Harmony support who excels at enabling skill-point-hungry damage dealers by raising the team's maximum skill points to six and recovering four with her ultimate. Her skill grants party-wide crit damage based on her own crit damage, so stacking that stat on her directly amplifies every ally's output. In mono-Quantum teams, her Nocturne bonus provides up to +30% attack depending on how many Quantum teammates are present, making her especially valuable alongside characters like Qingque or Seele. A well-optimized Sparkle build focuses on crit damage, speed, and energy regeneration to maximize uptime on her buffs and ultimate.

Light Cone Choices

Sparkle's signature light cone, Earthly Escapade, is the top pick. It boosts her crit damage by 32%, which directly improves the buff her skill provides, and introduces the Mask mechanic. At the start of battle, Mask increases allies' crit rate by 10% and crit damage by 28% for three turns. Each time Sparkle recovers a skill point (e.g., via her ultimate), she gains a stack of Radiant Flame; at four stacks, she gains a new Mask, keeping the partywide crit bonuses active. If you lack the signature, Bronya's But the Battle Isn't Over is an excellent alternative. It grants 10% energy regeneration rate for more frequent ultimates, regenerates an extra skill point every two ultimates, and increases the next ally's damage by 30% after Sparkle uses her skill—synergizing well with her action advance. For four-star options, Planetary Rendezvous works in mono-Quantum teams by boosting same-type damage, while Past and Future provides a similar damage boost to the next acting ally.

Relic Setup

Messenger Traversing Hackerspace is the recommended four-piece relic set for Sparkle. Its two-piece bonus gives +6% speed, and the four-piece effect grants allies +12% speed for one turn after Sparkle uses her ultimate, allowing them to act faster and benefit from her buffs sooner. For main stats, prioritize crit damage on the chest piece, speed on the boots, and energy regeneration rate on the Planar Ornament link rope. If you plan to use Broken Keel as your planar set, aim for at least 20% effect resistance to unlock the +10% crit damage bonus for the whole team; this often requires a few substat rolls but is worth the investment.

Planar Ornaments

Broken Keel is the default planar set for Sparkle. It provides 10% effect resistance and, when total effect resistance reaches 30%, grants all allies +10% crit damage. This extra crit damage stacks additively with Sparkle's skill buff, further amplifying the squad. An alternative is Penacony, Land of the Dreams, which increases energy regeneration rate by 5% and boosts damage for all allies of the same damage type by 10%—ideal in a mono-Quantum composition since it requires no extra stat threshold. For a sphere, Quantum damage bonus is a strong choice if you're running Penacony, though defensive or HP options can work if survivability is a concern.

Ascension Materials

To fully ascend Sparkle, you will need the following:

• 15 Tatters of Thought
• 15 Fragments of Impression
• 15 Shards of Desires
• 65 Dream Flamer
• ~300,000 credits

Tatters of Thought can be obtained from the Penacony assignment Tranquillity of Vimala-Bhumi and from all three Golden Calyx stages on Penacony (which also yield XP materials or credits). The higher-tier Fragments and Shards are crafted from Tatters. Dream Flamer drops from the Crimson Calyx (Shape of Roast) on Penacony's Dreamscape. If you need additional credits or character XP, farming the Golden Calyx remains the most efficient method.
