Asta is widely regarded as one of the best Fire characters in Honkai Star Rail, especially when using the best build. She is a support unit and can be used for breaking shields and increasing the team’s SPD stat.

Upon the game‘s release, there were several debates on who sat at the top among Fire characters, with the options being Himeko, Asta, and Hook.

With Asta being able to deplete Fire shields very quickly, she rose toward the upper spectrums of the tier list. The only issue is that Asta needs plenty of resources before she can be the most effective in battle.

Best Team Comp for Asta in Honkai Star Rail

Seele pairs really well with Asta as the former can act as the primary DPS after the latter breaks the shields

Asta is a very situational unit, primarily used to break shields. She can buff allies, but there are other units who perform that task much more efficiently.

However, the best units you can pair with Asta for maximum efficiency in Honkai Star Rail are Seele, Tingyun, and a Healer Tank. Asta can break Fire shields very fast, and Seele can quickly burst down those weakened enemies.

Tingyun will provide damage buffs for the main DPS in combination with Asta’s SPD buffs. For a healer, we recommend Natasha or Bailu.
