Serval | Honkai: Star Rail

Overview

Lightning Erudition damage dealer who maintains Shock while dealing direct damage to several enemies.

Role

Multi-target damage dealer or specialized attack generator for The Herta.

Playstyle

Apply Shock with Skill, use Ultimate to extend it, and alternate Skill or Basic according to Energy and team resources.

Why It Works

Talent adds damage to Shocked enemies after Serval attacks, while Ultimate reaches every enemy.

Watch For

Shock enables her Talent, but her direct damage still benefits from CRIT. At E4, Ultimate can also apply Shock to enemies that lack it.

Playstyle

Combat Flow

Apply Shock to the important targets, then use Ultimate while its extension or damage is useful. Basic when Shock is maintained and Skill Points are needed; Skill when new targets need Shock or the extra damage and Energy matter.

Key Notes

Rock 'n' Roll raises Skill's Shock base chance from 80% to 100%; resistance can still prevent application.
Talent damage occurs after attacks against Shocked enemies and is additional damage, not a follow-up attack.
E2 restores Energy when Talent deals its additional damage, making Shock coverage important to Ultimate access.
Do not equip follow-up-only bonuses expecting Talent to activate them.
Passkey and Eagle trade personal damage for attack frequency in a dedicated The Herta setup.

Build & Investment

Light Cones

Primary

The Seriousness of Breakfast

Adds damage and gains ATK stacks as Serval defeats enemies.

Situational

Eternal Calculus

For populated waves: hitting different enemies builds ATK, and hitting at least three grants temporary SPD.

Situational

Passkey

For a dedicated attack-generation role: Skill restores additional Energy once per turn. Its low base stats reduce personal damage.

Relics

Primary

Band of Sizzling Thunder

Adds Lightning damage and one turn of ATK after Skill.

Situational

Eagle of Twilight Line

For a fast The Herta support setup: Ultimate advances Serval's action by 25%. The Wind damage two-piece bonus does not help Serval.

Firmament Frontline: Glamoth

For personal damage: grants ATK and damage at 135 or 160 SPD.

Alternative

Meet useful action timings, then balance CRIT and ATK for personal damage. Maintain adequate Shock reliability for the chosen enemies without adopting a universal Effect Hit Rate target.

Eidolon Investment

E0 provides Shock extension and multi-target damage. E2 helps Energy and E4 broadens Shock application; E6 improves damage against Shocked targets.

Breakfast serves personal damage, Eternal Calculus suits populated waves, and Passkey belongs to a specialized Energy-focused role.

Basic also deals 60% of its damage to a random adjacent target.

Talent's additional damage restores 4 Energy when triggered.

Ultimate has a 100% base chance to apply Skill-equivalent Shock to enemies that are not already Shocked.

Increases Serval's damage against Shocked enemies by 30%.

Teams

Recommended Teammates

The Herta

The Herta benefits from a second Erudition ally and frequent multi-target attacks. Serval can prioritize attack frequency through Passkey and Eagle, budgeting the repeated Skills needed.

Sunday

Sunday advances Serval, supplies Energy and buffs direct damage. The extra turns require Skill Points and should land during useful Shock coverage.
