Genshin Impact: Beidou Quick Character Guide

1) Wolf's Gravestone (ATK: 608 • ATK: 49.6%)

[Refinement 1] Increases ATK by 20%. On hit, attacks against opponents with less than 30% HP increase all party members' ATK by 40% for 12s. Can only occur once every 30s.
Note: Serpent Spine is a fine choice for Off-Field DPS Beidou and can outperform Wolf's Gravestone by a significant margin when Bennett/Sara ATK buffs are applied. Be sure to use Beidou in slot 1 to pre-stack Serpent Spine before starting an abyss floor. At high refinement, Serpent Spine has the potential to be Beidou's best weapon, especially at low-medium ER requirements.

2) Beacon of the Reed Sea (ATK: 608 • Crit Rate: 33.1%)

[Refinement 1] After the character's Elemental Skill hits an opponent, their ATK will be increased by 20% for 8s. After the character takes DMG, their ATK will be increased by 20% for 8s. The 2 aforementioned effects can be triggered even when the character is not on the field. Additionally, when not protected by a shield, the character's Max HP will be increased by 32%.
Note: Depending on the amount of ATK% buffs you're getting, this weapon (and Redhorn Stonethresher) can overtake Wolf's Gravestone in personal damage. Beacon ranking assumes one stack.

3) Redhorn Stonethresher (ATK: 542 • Crit DMG: 88.2%)

[Refinement 1] DEF is increased by 28%. Normal and Charged Attack DMG is increased by 40% of DEF.

4) The Unforged (ATK: 608 • ATK: 49.6%)

[Refinement 1] Increases Shield Strength by 20%. Scoring hits on opponents increases ATK by 4% for 8s. Max 5 stacks. Can only occur once every 0.3s. While protected by a shield, this ATK increase effect is increased by 100%.

5) Akuoumaru (ATK: 510 • ATK: 41.3%)

[Refinement 1] 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%. A maximum of 40% increased Elemental Burst DMG can be achieved this way.
Note: Assuming 260 team energy, this weapon outperforms Skyward Pride on a low ER requirement Beidou (where she is paired with other Electro characters to battery her energy needs). At [R3+], it becomes exponentially better and comes very close to Serpent Spine and Wolf's Gravestone.

6) Luxurious Sea-Lord (ATK: 454 • ATK: 55.1%)

[Refinement 5] Increases Elemental Burst DMG by 24%. When Elemental Burst hits opponents, there is a 100% chance of summoning a huge onrush of tuna that deals 200% ATK as AoE DMG. This effect can occur once every 15s.

7) Rainslasher (ATK: 510 • Elemental Mastery: 165)

[Refinement 1] Increases DMG against opponents affected by Hydro or Electro by 20%.
Note: At max refinement in Aggravate teams this weapon will perform slightly better than Luxurious Sea-Lord.

8) Prototype Archaic (ATK: 565 • ATK: 27.6%)

[Refinement 1] On hit, Normal or Charged Attacks have a 50% chance to deal an additional 240% ATK DMG to opponents within a small AoE. Can only occur once every 15s.

5) Skyward Pride (ATK: 674 • Energy Recharge: 36.8%)

[Refinement 1] Increases all DMG by 8%. After using an Elemental Burst, Normal or Charged Attack, on hit, creates a vacuum blade that does 80% of ATK as DMG to opponents along its path. Lasts for 20s or 8 vacuum blades.

6) Prototype Archaic (ATK: 565 • ATK: 27.6%)

[Refinement 1] On hit, Normal or Charged Attacks have a 50% chance to deal an additional 240% ATK DMG to opponents within a small AoE. Can only occur once every 15s.

[Refinement 1] Increases DMG against opponents affected by Hydro or Electro by 20%.

1) 4-Pc Emblem of Severed Fate

2-Piece Bonus: Energy Recharge +20%
4-Piece Bonus: Increases Elemental Burst DMG by 25% of Energy Recharge. A maximum of 75% bonus DMG can be obtained in this way.
Note: Even after considering the 4-piece set effect, you should refrain from investing into Energy Recharge beyond what is needed to burst off cooldown as it will result in a damage loss as compared to prioritising offensive stats such as ATK/Crit. In team comps where Beidou has low ER requirements (i.e. when paired with Electro batteries), a Noblesse Oblige (2) / Thundering Fury (2) / +18% ATK set (2) [Choose Two] will outperform Emblem of Severed Fate (4).

2) Noblesse Oblige (2) / Thundering Fury (2) / +18% ATK set (2) / Emblem of Severed Fate (2) [Choose Two]

3) 4-Pc Thundersoother

2-Piece Bonus: Electro RES increased by 40%.
4-Piece Bonus: Increases DMG against opponents affected by Electro by 35%.
Note: This set works best in teams where you can maintain near perfect uptime on its passive, such as in Electro-Charged, Mono Electro and Aggravate teams.
