Beidou Build & Teams: 4-Star Electro On-Field Applicator & Battery

How Beidou Works

Beidou is the classic "on-field sub-DPS + battery":

• Skill "Lightning Tidecaller": while empowered, Normal/Charged Attacks deal Electro, apply it continuously, and proc Energy particles on hit.
• Empowered hits trigger Electro-Charged/Aggravate at high frequency (multi-hit).
• She's both a damage source (on-field Aggravate) and the team's Electro ER core — dual role.

Artifacts

Set	2pc	4pc
Thundering Fury	+15% Electro DMG	+40% Overload/Aggravate/Superconduct/Hyperbloom; after triggering, E CD −1s (once/0.8s) — top for the sub-DPS
Instrument of the Fortified Will	+20% ER	Team DMG buff after teammates' Bursts; pure battery slot
The Exile	+18% Electro DMG	DMG bonus when Electro-infused; pure on-field Electro

Main & Sub Stats

Slot	Main Stat
Sands	ATK% (on-field DPS) / Energy Recharge (battery slot)
Cup	Electro DMG Bonus
Circlet	Crit Rate / Crit DMG

Sub-stat priority: Crits > ATK > ER > EM. On-field Aggravate leans Crits; a pure battery leans ER.

Weapons

Weapon	Rarity	Notes
Wolf's Gravestone	5★	Team ATK on low-HP hits; on-field damage
Redhorn Stonethresher	5★	ER substat; fits the battery build
Prototype Archaic	4★	ATK%; craftable, top F2P pick

Team Comps

Charged / Taser Team (classic)

Beidou (on-field Electro) + Fischl (off-field Electro) + Xingqiu (Hydro/Sub-DPS) + Sucrose/Kazuha (grouping/shred)

• Electro Resonance + Xingqiu's Hydro → constant Electro-Charged.
• Beidou's empowered multi-hit fires at high frequency; Sucrose groups + shreds Electro RES.

Aggravate Team

Beidou + Fischl + Nahida (Dendro/EM) + Yaoyao/Baizhu (healer)

• Nahida applies Dendro + Beidou/Fischl apply Electro → target stays Quicken'd.
• Beidou's on-field Normal Attacks trigger Aggravate; Thundering Fury 4pc amplifies it.

Superconduct Physical Team

Beidou (Electro) + Eula/Razor (Physical DPS) + Zhongli (shield/shred) + Diona/Rosaria (Cryo)

• Cryo + Electro trigger Superconduct, shredding 40% Physical RES for the physical carry.

Constellation Priority

• C2: extends the empowered "Lightning Tidecaller" window — the biggest on-field damage upgrade, top value.
• C1: ER/shield after Burst, smoother battery play.

FAQ

Is Beidou a main DPS or sub-DPS?

She's an on-field sub-DPS and battery. She's both a high-frequency Aggravate source and the team's ER core, so she does more than a single-role carry.

Beidou or Fischl?

Fischl is more hands-off (Oz applies Electro off-field); Beidou is stronger on-field (multi-hit + ER). They can even run together. Use Beidou on-field if you lack Fischl, and vice versa.

What set does Beidou use?

Thundering Fury 4pc for on-field Aggravate (reactions +40%). For a pure battery slot, use Instrument of the Fortified Will 4pc. Main stat ATK vs ER follows her role.

No 5-star weapon — what's the F2P pick?

Prototype Archaic (craftable ATK%) > Favonius Greatsword (ER) > Whiteblind/Sacrificial. Forge Prototype Archaic for now.

Can Beidou clear the Spiral Abyss?

Yes. Aggravate/Charged teams are her home turf. Pair her with Nahida, Raiden and Yaoyao for a F2P-friendly 12-star Electro core.
