Honkai Star Rail Sparkle Build Guide

Sparkle is a 5-star character who uses Quantum elements and follows the Path of Harmony. She is one of the few 5-star Harmony characters and a member of the Masked Fools. She is mysterious, tricky, and loves playing different roles. She has many faces and wears various masks, not caring about wealth, status, or power. The only thing that captures her interest is having fun or being amused.
Sparkle boosts a team's damage and offers extra Skill Points. Thanks to a bonus Trace, Sparkle is especially beneficial when teamed up with other Quantum characters.

Abilities

Effect

Basic Attack

Monodrama

Deals Quantum damage equal to 50% of Sparkle's attack to a single enemy.

Skill

Dreamdiver

Boosts an ally's Crit Damage by 12% of Sparkle's Crit Damage plus 27% for one turn. Also, moves the ally's action forward by 50%. When used on Sparkle herself, the Action Advance effect doesn't trigger.

Ultimate

The Hero with a Thousand Faces

Restores four Skill Points for the team and gives all allies Cipher. When Cipher allies trigger Sparkle's Talent for a damage boost, each stack amplifies its potency by an extra 6%, extending over a span of two turns.

Talent

Red Herring

When Sparkle is on the field, the maximum number of Skill Points increases by two. When an ally consumes one Skill Point, it boosts the damage of all allies by 3% for two turns. This effect can stack up to three times.

Technique

Unreliable Narrator

Grants all allies Misdirect for 20 seconds. Characters with Misdirect won't be detected by enemies, and entering battle in Misdirect recovers three Skill Points for the team.

Traces

Almanac

When using her Basic attack, Sparkle regenerates an extra 10 Energy.

Traces

Artificial Flower

The Crit Damage Boost effect from Sparkle's Skill extends until the start of the target's next turn.

Traces

Nocturne

Enhances the attack of all allies by 15%, with an additional 5%/15%/30% increase in attack for Quantum-Type allies when 1/2/3 Quantum characters are present on your team.

Eidolons

Effect

E1

Suspension of Disbelief

The Cipher effect extended by Sparkle's Ultimate now lasts for an extra turn, and all allies affected by Cipher experience a 40% increase in their attack.

Purely Fictitious

Each Talent stack enables all allies to ignore 8% of the enemy target's defense when dealing damage.

Pipedream 

Enhances the level of Sparkle's Skill by two, with a maximum upgrade level of 15. It also enhances the level of her Basic Attack by one, with a maximum upgrade level of 10.

Life Is a Gamble

Sparkle's Ultimate restores one extra Skill Point, and her Talent increases the maximum number of Skill Points by an additional point.

Parallax Truth

Boosts the level of Sparkle's Ultimate and Talent by two, with a maximum upgrade Level of 15.

Narrative Polysemy

The Crit Damage Boost effect of Sparkle's Skill is additionally boosted by 30% of Sparkle's Crit Damage. When she activates her Skill, the Crit Damage Boost effect extends to all allies currently under Cipher. When Sparkle uses her Ultimate, this effect spreads to all allies under Cipher if the allied target has the Crit Damage increase effect provided by the Skill active on them.

Earthly Escapade

★★★★★

Optimal 5-Star Choice

The best Light Cone for Honkai Star Rail Sparkle is the 5-star Earthly Escapade. It provides a permanent Critical Damage bonus to the entire team. Also, the Mask effect raises allies' Critical Rate and Critical Damage for three turns at the beginning of the battle. With Sparkle's Ultimate, recovering four Skill Points, it becomes easy to accumulate the four Radiant Flame stacks required to activate the Mask effect again.

But the Battle Isn't Over

★★★★★

Alternative 5-Star Option

Another excellent 5-star Light Cone option is But the Battle Isn't Over because it makes energy regeneration easier. While the extra Skill Point can be beneficial, its usefulness depends on your team composition. Recovering 5 Skill Points simultaneously is significant, so teams with lower Skill Point requirements may gain more than they use.

Dance! Dance! Dance! 

★★★★

Alternative 4-Star Option

The best 4-star Light Cone for Sparkle is Dance! Dance! Dance! It advances allies' actions forward each time Sparkle uses her Ultimate. Given that the best Sparkle builds prioritize high Speed and Energy stats, this effect triggers frequently. Carve the Moon, Weave the Clouds is another strong 4-star choice; despite offering one of three random effects, each is well-suited for a Sparkle team.

Messenger Traversing Hackerspace

The Best Relic set for your Sparkle build is the 4-piece Messenger of Traversing Hackerspace set because Sparkle needs a lot of Speed. Since Sparkle frequently utilizes her Ultimate, the 4-piece set effect, which provides a Speed bonus for the entire team, is consistently triggered. If you currently lack enough Messenger Relics for your Sparkle build, you can temporarily combine the 2-piece set with a 2-piece Genius of Brilliant Stars, Musketeer, or Prisoner set.

Eagle of Twilight Line

This is the second-best set for Sparkle. It is most effective for Sparkle when she attains 160 SPD. This enables her to move forward in the turn order.

Broken Keel

Broken Keel is the best Planar Ornament for Sparkle because it provides CRIT DMG to herself and other party members. But remember that, Sparkle needs at least 30% Effect RES to activate the ornament's Critical Dmg effect.

If your Sparkle build is tailored for a Quantum-only team, opt for the Penacony, Land of the Dreams set instead of the Broken Keel set, as it provides an outstanding damage bonus for the team.
