Serval GUIDE

Understand Serval

Useful when…

Applying Shock across groups with her Skill.
Dealing all-enemy damage and extending existing Shock with her Ultimate.
Adding damage to Shocked enemies after Serval attacks.

Attacks and Shock

Her Skill hits one target and adjacent enemies, with a base chance to Shock enemies hit for two turns. Shock deals Lightning damage at the start of the affected enemy’s turn. Her Talent deals additional Lightning damage to all Shocked enemies after she attacks. Her Ultimate hits all enemies and extends the Shock duration of enemies already Shocked by two turns. The description does not specify whether the Ultimate hit can also apply Shock. Her Technique attacks one random enemy and has a base chance to Shock all enemies when combat begins.

Practical use and investment

Use the Skill against groups to damage its primary target and adjacent enemies, then use the Ultimate to hit all enemies and extend Shock already on them. Her damage effects scale from ATK. Skill investment supports its multi-target damage and Shock chance; Ultimate investment supports its all-enemy hit and Shock extension; Talent investment supports additional damage against Shocked enemies. Basic ATK is a single-target option. Promotion and bonus traces are separate progression tracks; bonus traces include CRIT Rate and Effect Hit Rate boosts.

Limits and comparison

The Skill’s Shock chance is a base chance applying to enemies hit, and the Ultimate’s stated extension applies only to enemies already Shocked. The Skill deals less damage to adjacent targets than to its primary target. Kafka is another listed Lightning character, but she follows Nihility while Serval follows Erudition; the available facts do not establish that Kafka is a direct replacement.

Limitations and tradeoffs

Shock and Talent damage depend on enemies being Shocked; the Ultimate extends Shock on enemies already affected.
The Skill’s adjacent targets take less damage than its chosen target.

Common mistakes to avoid

Assuming the Ultimate cannot apply Shock; its description only specifies extending existing Shock.
Assuming the Skill’s base Shock chance applies only to its primary target.
Using the primary-target damage as the adjacent-target damage.
