Best Light Cones
#1
Night on the Milky Way (S1)
Top option especially for Pure Fiction. For every enemy on the field, increases ATK by up to 15% (5 stacks). When an enemy is inflicted with Weakness Break, DMG increases by 50% for 1 turn. Best-in-slot for multi-target scenarios.
#2
Eternal Calculus (S5)
Increases ATK by 12% and gains additional ATK stacks per enemy hit, up to 5. Grants 16% SPD when 3 or more targets are hit. Strong in multi-enemy Pure Fiction content.
#3
Geniuses' Repose (S5)
Increases ATK by 32% and boosts CRIT DMG by 48% for 3 turns after defeating an enemy. Solid generalist option available from Stellar Warp.
#4
The Seriousness of Breakfast (S5)

Cavern Sets
1
Pioneer Diver of Dead Waters
Best-in-slot cavern set when you can maintain 3 debuffs on enemies. The 4-piece bonus increases CRIT Rate by 4% and grants up to 12% CRIT DMG against enemies with 3+ debuffs. After inflicting a debuff, these effects double for 1 turn. Serval's Shock qualifies as a debuff, making this consistently strong.
2
Band of Sizzling Thunder
Excellent alternative. The 2-piece grants 10% Lightning DMG and the 4-piece increases ATK by 20% for 1 turn after using Skill. Since Serval uses her Skill frequently to apply Shock, this bonus has nearly 100% uptime. Straightforward and reliable.
3
Scholar Lost in Erudition
Increases CRIT Rate by 8% (2-piece) and boosts Skill and Ultimate DMG by 20%, with an additional 25% Skill DMG boost after using Ultimate. Well-suited for Serval's Skill-heavy rotation and pairs well with her low-cost Ultimate.
Planar Ornament Sets
1
Firmament Frontline: Glamoth
Best planar set. Increases ATK by 12%. When SPD is at 135 or higher, deals 12% more DMG; at 160+ SPD, increases to 18% more DMG. With proper investment Serval easily hits the 135 threshold, and the 160 breakpoint is the target for The Herta team builds.
2
Space Sealing Station
Increases ATK by 12% and adds another 12% ATK when SPD is 120 or higher. A simpler and more accessible option if SPD building is difficult, as the 120 SPD requirement is easy to meet.
S
Eagle of Twilight Line: Specialist
After Serval uses her Ultimate, her action is Advanced Forward by 25%. Used exclusively in The Herta team where Serval acts as a fast stack generator. Sacrifices personal damage to dramatically increase the speed at which Serval can cycle her Ultimates to generate Herta's stacks.
Best Teams for Serval
Serval's primary role in endgame content is as a stack and Energy generator for The Herta. She can also function as an independent Lightning DPS, where she benefits from buffers that grant additional actions or ATK amplification.
01 · The Herta Core
Best endgame composition
Serval uses Passkey + Eagle of Twilight Line to spam Ultimates and generate stacks for The Herta as quickly as possible. Tribbie amplifies the team. Aventurine provides shielding without requiring heals. This is the primary endgame use case for Serval per MoC statistics.
02 · The Herta + Hyacine
Heal-based sustain variant
Hyacine replaces Aventurine as the sustain option for players without a shield sustain. Both compositions appear in top MoC clears for Serval. Choose based on availability and personal preference.
03 · Serval DPS · Buffer Core
Serval as primary damage dealer
04 · F2P · Super Break

Echo Chamber
Basic ATK deals Lightning DMG equal to 60% of the Basic ATK's DMG to a random enemy adjacent to the target of the Basic ATK. Adds a splash component to the Basic ATK, improving its coverage in multi-enemy scenarios.
Minor Upgrade

Encore!
Every time Serval's Talent is triggered to deal Additional DMG, she regenerates 4 Energy. Since the Talent triggers on all Shocked enemies after each attack, this can generate significant bonus Energy each turn, especially in multi-target fights.

Listen, the Heartbeat of the Gears
Skill Lv. +2 (max 15) and Basic ATK Lv. +1 (max 10). Increases Skill damage output, which is Serval's primary source of Shock application and a major damage contributor.
Solid Upgrade

Make Some Noise!
Ultimate has a 100% base chance to apply Shock to any enemies not currently Shocked. This Shock has the same effects as the one applied by Skill. A transformative quality-of-life improvement that resolves Serval's single biggest weakness: difficulty spreading Shock to all enemies. Dramatically reduces required Effect HIT Rate.

Belobog's Loudest Roar!
Ultimate Lv. +2 (max 15) and Talent Lv. +2 (max 15). Increases the damage of both her AoE Ultimate hit and her Talent's additional hits on Shocked enemies. Meaningful but not transformative on its own.

This Song Rocks to Heaven!
Serval deals 30% more DMG to Shocked enemies. Since her Talent triggers on all Shocked targets and her goal is to keep all enemies Shocked, this is effectively a near-permanent 30% DMG amplifier that pushes her from E0's 100% baseline to 145% in 3-target scenarios.
Massive Upgrade
Major Traces
Rock 'n' Roll
Ascension 2
Skill has a 20% increased base chance to Shock enemies, bringing the base chance from 80% to 100%. This is her most critical trace: the new 100% base chance means you only need about 67% Effect HIT Rate for a guaranteed Shock application against endgame enemies.
String Vibration
Ascension 4
At the start of battle, immediately regenerates 15 Energy. Combined with her 100 Energy cost Ultimate, this gives Serval a head start toward her first Ultimate, improving early-battle Shock extension and damage output.
Mania
Ascension 6
Upon defeating an enemy, ATK increases by 20% for 2 turns. Provides a damage boost during wave-clear content and Pure Fiction where enemies die frequently. Less impactful against single tough bosses.

Frequently Asked Questions
Yes, but primarily as a support for The Herta. As a dedicated Lightning DPS she is outclassed by other options, but she fills a specific niche as a free unit that can cycle Ultimates quickly to generate stacks for The Herta. If you have The Herta and no other Lightning Erudition units, Serval is well worth investing in. As a standalone DPS, she is decent for early-to-mid game content.
After Serval uses any attack (Basic ATK, Skill, or Ultimate), she deals additional Lightning DMG equal to 72% of her ATK to every enemy that is currently Shocked. This means if all five enemies are Shocked and you Basic ATK one, the Talent will still hit all five. The additional hit can CRIT, making CRIT stats valuable despite her DoT identity. This is why keeping Shock on all enemies is so important: more Shocked enemies means more Talent procs.
Before the A2 trace (Rock 'n' Roll), Serval's Skill only has an 80% base chance to Shock, which is low for endgame enemies with high Effect RES. Her Skill also uses Blast targeting, hitting only the main target and adjacent enemies, meaning she cannot directly Shock more than 3 enemies at once. The A2 trace raises this to 100% base chance, greatly improving consistency. E4 solves the targeting issue entirely by allowing her Ultimate to apply Shock to all enemies not yet Shocked.
With the A2 trace active (100% base Shock chance), Serval needs approximately 67% Effect HIT Rate for a guaranteed Shock application against standard endgame enemies. Her minor traces already provide +18% Effect HIT Rate, so you need roughly 49% from substats and other sources. Do not neglect this stat; failing to apply Shock means her Talent deals no damage at all.
CRIT stats. Despite having a DoT (Shock), Serval is more of a traditional damage dealer who cares about CRIT Rate and CRIT DMG because her Talent's additional hits can CRIT. Building pure ATK for DoT damage is suboptimal. Target 65–75% CRIT Rate and 130–150%+ CRIT DMG for best performance. The Shock DoT component is a bonus on top of her CRIT-based damage, not the primary focus.
In The Herta teams, Serval uses the Passkey Light Cone and the Eagle of Twilight Line planar set. Passkey generates extra Energy on Skill use, while Eagle of Twilight Line advances Serval's action after each Ultimate. This allows her to act extremely frequently, spamming Ultimates to generate stacks for The Herta. In this role she sacrifices personal damage output in exchange for dramatically boosting The Herta's damage. Target 160+ SPD to maximize action frequency.
