About Sparxie

Sparxie works by entering a livestream state that transforms her Basic Attack into a powerful Blast attack called “Bloom! Winner Takes All.” This enhanced attack hits the main target and adjacent enemies. The key mechanic is Engagement Farming, which triggers extra hits and stacks damage as the fight progresses.
Her Skill starts the livestream connection without consuming a Skill Point, making her surprisingly SP-friendly for a main DPS. Each Engagement Farming proc buffs her Bloom attack and can grant Punchline currency or even extra Skill Points as gifts.
Her Ultimate grants Punchline points and deals Fire damage to all enemies. The more Elation teammates you have, the more Punchline you gain. Punchline then converts into teamwide CRIT DMG buffs and Thrill stacks. When her ATK exceeds 2000, she gains additional Elation scaling, making ATK an important offensive stat.
The Certified Banger talent adds random extra hits to her finisher for every Engagement Farming proc. Her Elation Skill cashes in Punchline for Thrill, which can offset SP costs since spending Thrill counts as spending Skill Points.
Best Light Cones for Sparxie

Choosing the right light cone significantly improves Sparxie’s damage and Elation generation. Here are the best options:
| Light Cone | Rarity | Why It’s Good |
| Dazzled by a Flowery World | 5-Star | Her signature with CRIT DMG, increased SP limit, and DEF ignore |
| Today’s Good Luck | 4-Star | Best 4-star option with CRIT Rate and Elation stacking |
| Mushy Shroomy’s Adventures | 4-Star | Provides Elation boost and increases Elation DMG taken by enemies |
Best Relics for Sparxie
Relics are crucial for building Sparxie correctly. Here’s what you need:
Best Relic Set
The 4 piece Magical Girl’s Shining Medal is Sparxie’s best relic set. The 2 piece bonus gives 16% CRIT DMG. The 4 piece bonus makes Elation DMG ignore 10% of target DEF. For each 5 accumulated Punchline stacks allies gain, the Elation DMG additionally ignores 1% DEF, stacking up to 10 times for a total of 20% DEF ignore.
This set is perfectly designed for Sparxie’s kit since she constantly generates Punchline through her rotation and benefits massively from both the CRIT DMG and DEF shred mechanics.
Best Planar Ornaments
For planar ornaments, use Livestream’s Protean Vistas for maximum damage. This set provides 16% CRIT DMG baseline. When you consume 3 or more Skill Points in the same turn, it increases CRIT DMG by an additional 32% for 3 turns. Since Sparxie can easily consume multiple Skill Points in a single turn, this set is tailor-made for her playstyle.
Main Stats and Substats
Focus on these stats for maximum effectiveness:
Main Stats:
- Body: CRIT Rate
- Feet: ATK%
- Planar Sphere: ATK%
- Link Rope: ATK%
Substats Priority:
- CRIT Rate
- CRIT DMG
- ATK%
- Speed
The focus on ATK main stats is important because Sparxie gains extra Elation when her ATK exceeds 2000. For every 100 points above 2000, she gains 4% Elation, up to a maximum of 80% bonus Elation. This makes ATK both an offensive and scaling stat for her.
Best Team Compositions
Sparxie works best with other Elation characters and strong supports. Here are some of the best team options:
- Premium Elation Team: Sparxie + Yao Guang + Sparkle + sustain
- Alternative Support Team: Sparxie + Yao Guang + Robin + sustain
- Balanced Team: Sparxie + Sparkle + flex support + sustain
Yao Guang is currently the only other Elation unit available and has heavy synergy with Sparxie. Yao Guang provides increased Certified Banger uptime, Skill Points for the team, and additional Elation generation.
Sparkle provides extra SP, CRIT DMG buffs, and action advance. While she is a good support option, Sparxie prefers Elation units on the team, so Sparkle may decrease in value as more Elation characters release.
Robin works as a universal support providing ATK buffs, CRIT DMG, and additional damage through her concert mechanic. She fits into most team compositions.
Trace Priority
Level Sparxie’s traces in this order:
- Elation Skill and Ultimate
- Talent
- Skill
- Basic Attack
For bonus abilities, prioritize them based on their impact on your team composition and playstyle. Focus on traces that improve Elation generation and Punchline accumulation first.
Eidolons Worth Considering
Sparxie’s Eidolons provide significant power increases but are not necessary for her to function. Her E1 grants 5 extra Punchlines when Aha Instant ends and increases all allies’ All Type RES Penetration by 1.5% per Punchline owned, up to 15%. Her E2 gives an extra turn after Aha Instant ends plus 2 Thrill stacks for increased CRIT DMG.
However, Sparxie functions perfectly well at E0 with proper team building and relic investment. Save your pulls for other characters or light cones unless you are heavily investing in Elation teams.
