Pros & Cons

Excellent DPS unit
- One of the highest DPS ceilings in the game
- Flexible as you just want a driver/trigger for her Burst
Core of most Taser comps
Powerful constellations
Great unit available in Paimon's Bargains

C2 is a massive damage increase (up to 66% damage increase)
- As an early constellation, some would advise not using Beidou until she's C2
Needs multiple targets (Ideally 2) to unlock damage
Flexible with energy requirements but you'll generally want to bring an Electro battery
Lacks access to reactions that scale up her own damage
Hard to optimize stats

Builds

Off-Field DPS Build

Beidou can be an On-field DPS but her kit was designed with flexibility of having other units trigger her Burst so playing her as an Off-field DPS plays towards that strength. Regardless of field-time, Beidou will deal lots of damage and its better to play through her (with your trigger as a co-star/enabler) rather than have her support your trigger.

Talent Priority

Burst > Skill
Most of Beidou's damage comes from her burst, her counters can do a good amount of damage if you can consistently land them.

Stat Priority

Main stats: ATK/Electro/Crit
Substats: Crit/ATK/ER
In optimized builds, you really don't want to sacrifice the ATK% sands piece for an ER sands piece.

Weapons

Best Weapons

Wolf's Gravestone is ranked highest due to its massive ATK stats as well as its team ATK buff from its passive.

Wolf's Gravestone

ATK

Wolfish Tracker

Increases ATK by 20~40%. On hit, attacks against opponents with less than 30% HP increase all party members' ATK by 40~80% for 12s. Can only occur once every 30s.

Thrilling Tales of Dragon Slayers (TTDS) or Bennett allows this weapon to push past Wolf's Gravestone. Beidou's Burst being static/snapshot allows her to bypass the downsides of the passive. Overall, Serpent Spine provides a lot of stats that at R1 its a fine weapon and at R5 this can be her best weapon.

Serpent Spine

CRIT Rate

Wavesplitter

Every 4s a character is on the field, they will deal 6~10% more DMG and take 3~2% more DMG. This effect has a maximum of 5 stacks and will not be reset if the character leaves the field, but will be reduced by 1 stack when the character takes DMG.

Weapon Variations

Decent Damage

On Beidou's common comps this weapon beats R5 Sea-Lord at R1. R3 is the comfortable breakpoint and at R5 it's better than most 5★ weapons.

Akuoumaru

ATK

Watatsumi Wavewalker

For every point of the entire party's combined maximum Energy capacity, the Elemental Burst DMG of the character equipping this weapon is increased by 0.12~0.24%. A maximum of 40~80% increased Elemental Burst DMG can be achieved this way.

Burst Uptime

Relevant in comps that need more ER. Overcapping ER on Beidou hurts this weapon's ranking over alternatives.

Skyward Pride

Energy Recharge

Sky-ripping Dragon Spine

Increases all DMG by 8~16%. After using an Elemental Burst, Normal or Charged Attack, on hit, creates a vacuum blade that does 80~160% of ATK as DMG to opponents along its path. Lasts for 20s or 8 vacuum blades.

This weapon is only relevant if you can consistently get good skill counters as Beidou.

Sacrificial Greatsword

Energy Recharge

Composed

After dealing damage to an opponent with an Elemental Skill, the skill has a 40~80% chance to end its own CD. Can only occur once every 30~16s.

F2P Options

Beidou's main F2P weapon. It provides lots of ATK and burst DMG buff but it is unfortunately an event-exclusive weapon.

Luxurious Sea-Lord

ATK

Oceanic Victory

Increases Elemental Burst DMG by 12~24%. When Elemental Burst hits opponents, there is a 100% chance of summoning a huge onrush of tuna that charges and deals 100~200% ATK as AoE DMG. This effect can occur once every 15s.

Slightly worse stats than Sea-Lord but a cost-effective option.

Prototype Archaic

ATK

Crush

On hit, Normal or Charged Attacks have a 50% chance to deal an additional 240~480% ATK DMG to opponents within a small AoE. Can only occur once every 15s.

It's a good weapon but it relies on keeping its passive active for full potential. Additionally, 24 starglitter is expensive.

Blackcliff Slasher

CRIT DMG

Press the Advantage

After defeating an opponent, ATK is increased by 12~24% for 30s. This effect has a maximum of 3 stacks, and the duration of each stack is independent of the others.

Beidou does count towards the passive and it needs refines for the passive to truly shine.

Lithic Blade

ATK

Lithic Axiom - Unity

For every character in the party who hails from Liyue, the character who equips this weapon gains 7~11% ATK increase and 3~7% CRIT Rate increase. This effect stacks up to 4 times.

Artifacts

Best Sets

In general the best set for Beidou as you may feel the need for extra ER to comfortably Burst. Farming for this set is generally advised as this set is very good on a lot of units.
