Best Serval Honkai Star Rail build: Relics, Light Cones, Eidolons & Abilities

Serval is one of the strongest and most underrated units in Honkai Star Rail. However, she is a resource-heavy character and in order to utilize her strength, you need to spend some time building her optimally.
Serval is a Lightning Erudition character which means she can deal AoE damage to enemies. Her ability to break shields is unmatched which has helped her maintain a respectable position in various tier lists for Honkai Star Rail.
There have been a few opinions stating that Jing Yuan makes Serval an obsolete unit. However, it is important to remember that Jing Yuan is a 5-star unit and is extremely difficult to come by. In such cases, Serval is invaluable against every enemy with a Lightning shield in the game.
Here is our detailed guide for Serval in Honkai Star Rail, covering her abilities, best Light Cones, Relic sets, and team compositions.

Best Team Comp for Serval in Honkai Star Rail

Serval is an extremely versatile unit and you can run her with almost anyone and everyone. However, the optimal partners for Serval in Honkai Star Rail will be Fire Trailblazer, Tingyun, and Seele. This is because Fire Trailblazer will act as the tank that will protect the entire team.
Tingyun can buff Serval and also provide the latter with energy. Lastly, Seele will be the single target DPS in the team who can burst down enemies quickly. Serval is an AoE unit which means her damage against bosses will be sub-par.
Hence, Seele can help with that once Serval removes the shields from the boss or any enemy. However, this team is not final as you can replace Seele with Yanqing and Tingyun with Bronya. If you are having survivability issues then Tingyun can make way for Natasha for the heals.
