Beidou got significantly more powerful with his Constellations in Genshin Impact, and his best upgrades are easy to obtain.
Constellations are a huge strength in Genshin Impact, especially for 4-star characters. They can completely change a unit’s kit and make it more versatile to play more roles and even do its job better.
Genshin Impact – Beidou Constellation Guide

Beidou is not a good character in C0 in Genshin Impact. Her constellations ensure her everything she’s been missing to become a force to be reckoned with. However, players don’t have to wait long to get all of Beidou’s Constellations, as his C1 and C2 are the stars of his kit.
Both Constellations give Beidou the offensive and defensive strength that his teammates need to improve their performance. In short, yes, Beidou Constellations are worth it in Genshin Impact.
C1
- It is made: When Stormbreaker is used, it creates a shield that absorbs up to 16% of Beidou’s maximum HP for 15s. This shield absorbs Electro DMG 250% more effectively.
- Importance: Priority
C1 Beidou has one of the best passives a 4 star can have in Genshin Impact. When Beidou casts her Elemental Burst, she will create a shield that protects her team for 15 seconds with a good portion of her HP.
This shield is super important as it can effectively block incoming attacks, especially Electro.
C2
- It is made: Stormbreaker’s arc beam can bounce to 2 additional targets.
- Importance: Priority
The second Constellation of Beidou is just as important as the first. While the former improves Beidou’s survivability, the latter greatly increases his Elemental Burst, increasing his off-field damage.
C4
- It is made: When attacked, Beidou’s Normal Attacks gain an additional instance of 20% Electro DMG for 10s.
- Importance: Low
C4 Beidou is not that important for players. First, Beidou won’t use his normal attacks, and even if he did, it’s not an attractive addition to his damage output. Constellation does not infuse Beidou’s attacks with Electro, it just adds an extra Electro multiplier that inflicts a minuscule number.
C6
- It is made: For the duration of Stormbreaker, the Electro RES of surrounding opponents is reduced by 15%.
- Importance: High
C6 Beidou gets another offensive passive that increases his damage even more. Beidou’s performance with other Electro users in Genshin Impact greatly improves after obtaining his C6.
