Serval is a Lightning Erudition character who specializes in multi-target damage and Shock DoT application. Her Skill deals Lightning DMG to a primary target and adjacent enemies, with a chance to inflict Shock, causing damage over time each turn. Her Ultimate deals AoE Lightning DMG to all enemies and extends the duration of Shock debuffs, helping maintain consistent DoT uptime. Serval’s Talent also triggers bonus Lightning DMG to shocked enemies whenever she uses her Basic ATK, Skill, or Ultimate, making her well-suited for teams that focus on AoE damage and DoT amplification.
Best Cavern Relics
(2) Increases DMG dealt to enemies with debuffs by 12%.
(4) Increases CRIT Rate by 4%. The wearer deals 8%/12% increased CRIT DMG to enemies with at least 2/3 debuffs. After the wearer inflicts a debuff on enemy targets, the aforementioned effects increase by 100%, lasting for 1 turn(s).
Serval’s damage output mainly comes from inflicting Shock DoTs with her Skill. Equipping this set will significantly enhance her DoT effectiveness.
(2) Increases CRIT Rate by 8%.
(4) Increases DMG dealt by Skill and Ultimate by 20%. After using Ultimate, additionally increases the DMG dealt by the next Skill by 25%.
This set only amplifies her Skill and Ultimate damage but doesn’t improve her overall DoT output.
(2) Increases Lightning DMG by 10%.
(4) When the wearer uses their Skill, increases the wearer's ATK by 20% for 1 turn(s).
This can be considered for Serval, as it grants an ATK boost whenever she uses her Skill, providing better DoT damage output.
Best Planar Ornaments
(2) Increases the wearer's ATK by 12%. When the wearer's ATK is higher than or equal to 2,400/3,600, increases the DoT DMG dealt by 12%/24%.
This set significantly enhances Serval’s Shock DoT, and she only needs to reach 3,600 ATK to gain the high DoT boost. It is currently her best Planar Ornament and is also considered the top choice for most DoT-focused characters.
(2) Increases the wearer's ATK by 12%. When the wearer's SPD is equal to or higher than 135/160, the wearer deals 12%/18% more DMG.
Reaching the highest damage boost is somewhat complicated, as it requires Serval to have high SPD substat rolls. This makes it harder to stack ATK, which is also essential for maximizing her Shock DoT.

A Knight's Pilgrimage
Increases the wearer's CRIT DMG by 36~60%. When the wearer uses Ultimate, increases DMG dealt by the wearer's Ultimate based on their Max Energy. Each point of Energy increases DMG dealt by Ultimate by 0.36~0.60%. A max of 180 points of Energy will be taken into account for this.For Serval, prioritize ATK% first, as it directly increases her Shock DoT damage. Next, focus on Effect Hit Rate to improve the chance of inflicting Shock with her Skill. Speed is also important so she can act more often and refresh debuffs or use her Ultimate faster.

Long Night
Increases the wearer's CRIT DMG by 36~60%. Increases DMG dealt by the wearer's Skill and Ultimate by 18~30%. After the wearer uses Skill or Ultimate, gains Somnus Corpus. Upon triggering a follow-up attack, consumes Somnus Corpus, and increases DMG dealt by follow-up attack by 48~80%.Before Dawn is a solid Light Cone for Serval, as it greatly increases her Skill and Ultimate damage and provides a Crit DMG boost. However, since most of Serval’s damage comes from Shock DoT, this Light Cone doesn’t directly enhance her DoT output. It mainly improves her initial burst when applying Shock and dealing AoE hits

Meteor Swarm
For every enemy on the field, increases the wearer's ATK by 9.0~15.0%, up to 5 stacks. When an enemy is inflicted with Weakness Break, the DMG dealt by the wearer increases by 30~50% for 1 turn.Night on the Milky Way is a good Light Cone for Serval in multi-enemy battles, since it increases her ATK for each enemy on the field and provides an additional damage boost against enemies affected by debuffs—including her Shock. This makes it effective for enhancing both her Skill damage and DoT output. However, in single-target fights or short encounters, its value drops compared to other options that offer consistent ATK or DoT bonuses.
Boundless Thought
Increases the wearer's ATK by 8~12%. After using an attack, for each enemy target hit, additionally increases ATK by 4~8%. This effect can stack up to 5 times and last until the next attack. If there are 3 or more enemy targets hit, this unit's SPD increases by 8~16%, lasting for 1 turn(s).Eternal Calculus is a solid 4★ Light Cone option for Serval. It increases her damage against enemies affected by DoT, directly boosting her Shock DoT output. This makes it a good budget choice if you want to focus on maximizing her sustained damage over time. While it doesn’t provide as much burst as some 5★ Light Cones, it synergizes well with Serval’s playstyle of applying and maintaining Shock.
