Overview

F2P Lightning AoE DPS who applies Shock and hits all Shocked enemies with additional Lightning DMG on every attack. Excels in The Herta battery role or as an accessible general-purpose Lightning DPS with sufficient investment.

Lightning Erudition DPS who revolves around applying Shock and triggering Talent additional damage on all Shocked enemies with every attack. Skill applies Shock via Blast targeting, Ultimate extends Shock duration and deals AoE Lightning DMG. Talent procs additional Lightning DMG (72% ATK) on every Shocked enemy after each attack, including enemies not directly targeted. These Talent procs can CRIT, making CRIT stats essential despite her DoT nature.

Key Mechanics

Talent additional damage hits ALL Shocked enemies on every attack, even those not directly targeted. With 5 Shocked enemies, a single Basic ATK triggers 5 separate Talent procs (each eligible for CRIT), making enemy count a massive damage multiplier.
Shock application is the core bottleneck. Skill only hits 3 targets (main + adjacent), so in 4-5 enemy scenarios, some enemies remain unShocked. E4 solves this by letting Ultimate apply Shock to all non-Shocked enemies. Without E4, careful positioning and Effect Hit Rate investment are required.
Despite having DoT (Shock), Serval is primarily a CRIT-scaling DPS because Talent procs can CRIT. This creates an unusually demanding stat profile: she needs both 67%+ Effect Hit Rate for Shock guarantee AND competitive CRIT Rate/DMG for Talent damage.
In The Herta battery builds, Serval sacrifices personal damage (Passkey LC, Eagle set, Energy Regen rope) to maximize Ultimate frequency. Each AoE Ultimate generates Interpretation stacks for The Herta while E2 Talent Energy regen sustains the loop.

The Herta Battery

Serval acts as a dedicated Energy and Interpretation generator for The Herta. Equip Passkey and Eagle of Twilight Line to maximize Ultimate frequency — each Ultimate hits all enemies (generating Interpretation stacks) and triggers Eagle's action advance. With E2, cascading Talent Energy regen sustains the loop. Personal damage is largely sacrificed in exchange for dramatically amplifying The Herta's output.

Standard AoE DPS

Traditional CRIT-focused build where Serval acts as main Lightning DPS. Uses Pioneer Diver of Dead Waters or Scholar Lost in Erudition with damage-oriented light cones. Applies Shock with Skill and extends it via Ultimate, then hits all Shocked enemies with Talent additional damage on every attack. Performs best in Pure Fiction due to AoE coverage and Talent multi-proc potential.

Serval Investment Priority

E2 — Talent Energy regen (4 per proc) enables Ultimate loop in The Herta battery build. With multiple Shocked enemies each turn, this generates 12-20 Energy per round, making Ultimate spam viable without Energy Regen rope.
E4 — Ultimate applies Shock to all non-Shocked enemies at 100% base chance. Fixes the core weakness of missing Shock on 4-5 target waves, keeping Talent damage active across all enemies at all times.
E6 — Deals 30% more DMG to Shocked enemies — a universal multiplier across Skill, Ultimate, and all Talent procs. Worthwhile end-investment for committed Serval players.

Serval Relics and Stat Targets

Recommended: Pioneer Diver of Dead Waters with Firmament Frontline: Glamoth

Stat targets: CRIT Rate 70%+, CRIT DMG 140%+, ATK 2200-2600+, SPD 135-160+, Effect Hit Rate 67%+

Main stats: Body: CRIT Rate > CRIT DMG · Feet: SPD > ATK% · Sphere: Lightning DMG > ATK% · Rope: ATK% > Energy Regen

Best Serval Light Cones

Night on the Milky Way (Best in Slot): Best-in-slot for Pure Fiction and multi-target content. ATK stacks up to 5 times based on enemy count (up to 75% at S1), and Weakness Break triggers a 30% DMG bonus for 1 turn. Weakens significantly in single-target scenarios where stacks cannot be maintained.
Into the Unreachable Veil: Strong alternative on Serval. Provides CRIT Rate, Skill and Ultimate DMG bonus (60% at S1 after Ultimate), and SP recovery on Ultimate. The SP restoration is especially valuable in The Herta battery builds where Serval Ultimates constantly. Competitive with Night on the Milky Way in most content.
Eternal Calculus: Best 4-star option for Pure Fiction. ATK stacks per enemy hit (up to 5 stacks) and SPD increases when hitting 3+ enemies per attack. Requires multi-target scenarios to maintain value — falls off in MoC boss phases and Apocalyptic Shadow.
Geniuses' Repose: Accessible budget option. Provides ATK and a CRIT DMG buff on enemy defeat. More consistent across all modes than Eternal Calculus since the defeat trigger still fires in MoC and AS. Good baseline when no premium alternatives are available.

ATK stacks up to 5 times based on enemy count (up to 75% at S1), and Weakness Break triggers a 30% DMG bonus for 1 turn. Weakens significantly in single-target scenarios where stacks cannot be maintained.

How should I invest in Serval?

Important Notes

Shock application requires 67% Effect Hit Rate for guarantee with A2 trace — below this threshold, Talent damage drops sharply on missed Shocks.
E4 is strongly recommended for endgame — without it, Ultimate cannot apply Shock to non-Shocked enemies, leaving multi-target waves with coverage gaps.
Battery build (Passkey + Eagle) nearly eliminates personal damage in exchange for The Herta output — do not use this setup if running without The Herta.
Talent damage can CRIT but demands both CRIT investment and Effect Hit Rate simultaneously, making optimal stat distribution unusually demanding for a 4-star.
