Serval
Situational—Serval batteries The Herta or fills early Lightning AoE. Ultimate “Here Comes the Mechanical Fever” hits every enemy on the field in one cast. Best with The Herta / Sunday. As Herta battery: Eagle + Passkey Ult spam; personal DPS is mid. Skip when Jade/Anaxa already battery The Herta.
Serval is a 4★ Lightning Erudition Main DPS. Skill “Lightning Flash” is the primary in-combat spend. Ultimate “Here Comes the Mechanical Fever” is the payoff window for damage or team utility. This Phase 1 page covers kit text, gear targets, and pull notes—team comps stay empty until Phase 2.

Strengths
- Ultimate “Here Comes the Mechanical Fever” hits the full field and forces DoT application/detonation in one cast—Pure Fiction waves melt once the status is seeded.
- “Lightning Flash” Blast-hits the main target plus adjacent enemies, so adjacent elites still take meaningful chip without waiting for Ultimate.
- Talent “Galvanic Chords” seeds or detonates DoT statuses in the same cast—ignore it and Serval plays like a worse generic Erudition unit.
- Technique “Good Night, Belobog” hits every enemy on the field in one cast—skipping it is free damage left on the table.
Weaknesses
- If Energy or Skill Points starve “Here Comes the Mechanical Fever”, Serval spends turns on Basics and the kit’s advertised multipliers never show up on the combat log.
- As a 4★ Erudition unit, Serval is easy to gear for early/mid game but usually loses the niche race to a modern limited option once that banner is built.
- Spamming “Lightning Flash” every turn without watching Skill Points strands the rest of the team—Serval is often the SP sink.
- If “Here Comes the Mechanical Fever” is still offline at the end of a MoC cycle, the build is usually Energy/ERR or rotation order—not a missing CRIT roll.
Trace Priority
Here Comes the Mechanical Fever carries most of the kit’s damage or utility—level this first.
Galvanic Chords supports the main rotation—raise after the top priority traces.
Lightning Flash supports the main rotation—raise after the top priority traces.
Roaring Thunderclap is last priority outside of filling trace materials.
Stat Priority
Open with Technique if it helps, spend Skill to advance the kit’s resource, and hold Ultimate for the damage or buff window. Exact teammate order lands in Phase 2.
Open supports first, then spend the carry’s Skill/Ult inside the buff window. Exact order varies by the team tab above.
Light Cones
5★ · Path cone
For every enemy on the field, increases the wearer's ATK by #2[f1]%, up to 5 stacks. When an enemy is inflicted with Weakness Break, the DMG dealt by the wearer increases by 0.3% for 1 turn.
Why it works —Strong Erudition option for Serval; use while farming or if signature is unavailable.
5★ · Path cone
Increases the wearer's ATK by 0.08%. After using an attack, for each enemy target hit, additionally increases ATK by 0.04%. 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 0.08%, lasting for 1 turn(s).
Why it works —Best accessible option for most accounts—raise superimposition when copies drop.
4★ · Path cone
Increases the wearer's DMG by 0.12%. For every enemy defeated by the wearer, the wearer's ATK increases by 0.04%, stacking up to 3 time(s).
Why it works —Budget path cone—fine while building the account.
4★ · Path cone
After entering battle, increases the wearer's DMG based on their Max Energy. Each point of Energy increases DMG by #1[f2]%. A max of 160 Energy will be taken into account for this.
Why it works —Budget path cone—fine while building the account.
Relics
Team Compositions
Primary multi-target Erudition team for Serval. The Herta, Sunday, Huohuo are the partners the kit / endgame clears assume first.
Core carry for this shell — owns the damage plan and sets the rotation pace.
The Herta is the damage seat in this shell — build the supports around their rotation, not the reverse.
Sunday is the Advance / DMG amp — time their Skill/Ult for the carry’s damage window.
Huohuo covers healing (and often Energy / cleanse) so the carry can stay on-curve.
