Serval is a 4★ Lightning Erudition damage dealer. Her Blast Skill spreads Shock, her cheap 100-Energy AoE Ultimate extends it, and her Talent hits every Shocked enemy after each of her attacks. On her own she's mostly an early-game carry, but she keeps a niche as The Herta's Erudition partner, spamming Ultimates to feed her Energy and Interpretation stacks.

Guide
How to play
How she works
- Lightning Flash (Skill). Blast: 140% ATK on the target and 60% on adjacent enemies, with an 80% base chance (100% with her A2, Rock 'n' Roll) to Shock them for 2 turns. Shocked enemies take Lightning DoT equal to 104% of her ATK at the start of each turn.
- Here Comes the Mechanical Fever (Ultimate, 100 Energy). 180% ATK on all enemies, and enemies already Shocked stay Shocked for 2 more turns (at E4, it also Shocks the others).
- Galvanic Chords (Talent). After each of her attacks, every Shocked enemy takes Lightning Additional DMG equal to 72% of her ATK.
- Traces. String Vibration (A4): 15 Energy at the start of battle. Mania (A6): +20% ATK for 2 turns after defeating an enemy.
Rotation
- Use her Technique to start the fight with every enemy Shocked for 3 turns.
- Use her Skill on the largest group to spread Shock, then her Ultimate to extend it on everyone.
- Keep attacking: every hit triggers her Talent on all Shocked enemies.
Tips
- Despite her DoT, she scales with CRIT and ATK like a regular damage dealer.
- With The Herta, she uses a different build: Passkey, 4-piece Eagle of Twilight Line and 160 SPD to spam Ultimates. Each of her attacks gives The Herta Energy and Interpretation stacks, and as a second Erudition character she unlocks The Herta's +80% team CRIT DMG. Her E2 makes this much smoother.
- Her cheap Ultimate also makes her a decent Toughness breaker in Super Break teams with the Trailblazer (Harmony).
Strengths
- Reliable damage from her Talent and Shock
- Good single-target Toughness damage thanks to her Blast Skill
- Can keep enemies Shocked indefinitely
- Spammable 100-Energy Ultimate
- Budget Erudition partner for The Herta
Weaknesses
- Low damage ceiling (Prydwen T5 in every mode at E0)
- Still needs CRIT stats despite her DoT
- Struggles to Shock every enemy against 4–5 targets
- Relies on Eidolons for comfort
