You can have the most broken character inHonkai: Star Rail, but you still won’t be able to beat the endgame content until you put them in a synergistic team. You can have up to four characters in a team, and the battle’s outcome relies entirely on the units you use.
Support characters like Sparkle, who’s a five-star Quantum unit following the path of Harmony, are an integral part of your team. If you use her with the right team members, you’ll easily see over 100,000 damage every turn.

7Jing Yuan
Sparkle’s first limited banner in the second half of the Version 2.0 update came alongside a rerun of theGeneral of the Xianzhou Luofu himself, and coincidentally, they can also work quite well with each other. Jing Yuan gains stacks for his Lightning Lord whenever you use the Skill or Ultimate.
Ideally, you’d want to use his Skill every time he gets a turn, and the extra turns provided by Sparkle allow both him and the Lightning Lord to deal a lot more DMG. Moreover, Sparkle’s Artificial Flower bonus ability allows the Lightning Lord to enjoy the Crit DMG buff from her Skill as well.

6Yanqing
The synergy between Yanqing and Sparkle is almost too good, and she actually makes him viable for the endgame content. Whenever you use Yanqing’s Skill, you get the Soulsteel Sync effect that increases his Crit Rate and DMG while also giving him a chance to trigger a follow-up attack.
Using his Ultimate with the Soulsteel Sync active gives him even more Crit Rate and DMG. All of this stacks with the Crit DMG and normal DMG bonus provided by Sparkle to allow him to deal massive damage. Of course, you’ll need to build a ton of ATK on him to prevent diminishing returns.

5Huohuo
While Huohuo might not be the strongest character in lore, she’s turning out to be one of the strongest sustainers in the game. Apart from being able to heal your team and remove their debuffs, she can also grant a significant Energy and ATK bonus to your party with her Ultimate, giving her a hint of the Harmony path.
One of the main problems with Sparkle is the possible diminishing returns you’re able to get on the DPS unit with the whopping DMG boost. This can be prevented with the ATK boost from Huohuo, and the Energy Regeneration provided by her allows Sparkle to use her Ultimate more often.

4Misha
Misha is quite an interesting unit since a lot of his abilities are similar to Jing Yuan while he shares the path and combat type with one of thebest DPS units in the game. However, he can still be used alongside Sparkle if you don’t have access to Jingliu on your account.
His Skill grants him extra Hits Per Action for his Ultimate, which can be used to deal damage, freeze enemies, and reduce their Toughness bar monumentally. Paired with Sparkle, you may use all his abilities much more often.

3Argenti
The Knight of Beauty, Argenti, was released with quite a bang in Honkai: Star Rail since he had an entire path dedicated to him in the Simulated Universe. Unfortunately, he fell a little short in Memory of Chaos because of how long it took to get his Ultimate back if you don’t have both Tingyun and Huohuo in his team.
Thankfully, Sparkle can solve this issue if you give her a ton of SPD since she can essentially allow Argenti to get more turns. This also opens the way for you to build ATK Percent boots on him and get some extra damage overall.

2Qingque
Ever since the release of Honkai: Star Rail, Qingque has been one of the most fun DPS units since she allows you to gacha without having to spend your precious currency. Now that the game has a character to circumvent all the Skill Point problems, Qingque actually becomes a meta DPS unit.
You can get up to seven Skill Point slots when you have Sparkle on your team, which gives you enough chances to get all four similar Celestial Jade tiles with Qingque. Sparkle even has an entire Bonus Ability that gives you extra ATK on Quantum characters based on the number of characters from this combat type in your team.

1Dan Heng: Imbibitor Lunae
Finally, it’s no surprise that a five-star DPS unit that relies heavily on Skill Point usage works best in a team with Sparkle. Whenever Imbibitor Lunae gets a turn, you can use up to three Skill Points to enhance his Basic Attack. The more your enhancement levels, the more damage you’ll deal to the enemies.
While he can get two free Skill Points with his Ultimate, you’d still run into problems because of the high usage. This is completely circumvented if you use Sparkle, and his damage also gains a massive boost.
