Beidou
Who is Beidou?
Beidou is a 4★ Electro Claymore off-field sub-DPS from Liyue who becomes excellent with the right battery. Her Elemental Burst (Stormbreaker) fires off-field arc lightning that jumps between enemies whenever the active character attacks — her primary damage source. She also delivers strong parrying counter-damage via her Skill. Her main drawback is a very high Energy Recharge requirement (especially at low constellation), which demands a reliable Electro battery such as Fischl or Raiden Shogun. C2 is widely considered her best constellation. Source: https://keqingmains.com/q/beidou-quickguide/
Kit Summary
Hold the Skill to parry incoming attacks for a powerful Electro counter — a perfect counter yields maximum damage and 3 Energy particles; Tap Skill deals reduced damage with 2 particles.
Grants a shield and deploys arc lightning that jumps between up to 2 (C0) or 4 (C2) targets each time the active character attacks. Her main off-field damage source — snapshots buffs on cast.
Rarely used as her off-field contribution dominates.

📊 Substats Priority
👥 Best Teams
Quicken / Aggravate: Beidou + Dendro + secondary Electro (e.g., Fischl) + flex
Electro-Charged: Beidou + Hydro DPS + optional second Electro + Anemo
National Variant: Beidou + Fischl + Xiangling + Bennett
F2P Verdict
Fully viable at C0 but ER-hungry — target ~110–160% with Fischl present, or ~185–250% as solo Electro. Use Favonius Greatsword or Mailed Flower for the weapon slot. 4pc Emblem of Severed Fate covers her ER need while boosting Burst DMG. Perfect parrying with her Skill significantly lowers ER requirements. Her Burst snapshots: cast after Bennett/Kazuha/TTDS for max value. Source: https://keqingmains.com/q/beidou-quickguide/
Frequently Asked Questions
Is Beidou good for beginners?
She is effective once you have a battery (Fischl or Raiden Shogun) to meet her ER needs. Without a battery she is ER-starved and rotation-inconsistent. Source: KQM.
What is the best free weapon for Beidou?
Favonius Greatsword (Energy Recharge crutch) or Mailed Flower (event weapon — EM). Source: KQM.
What is Beidou's best constellation?
C2 — 'Stormbreaker's arc lightning can jump to 2 additional targets,' dramatically increasing AoE DPS. KQM calls it her best constellation. Source: KQM.
Why does Beidou need so much Energy Recharge?
Her Burst (Stormbreaker) costs 80 Energy and is her entire off-field kit; maintaining it every rotation requires a dedicated Electro battery like Fischl or Raiden Shogun. Source: KQM.
