Honkai: Star Rail's co-op gameplay comes in the form of friend support, which you can use to complete Calyxes, Stagnant Shadows, Caverns of Corrosion, and Echoes of War. The more your support is used, the more Credits you can earn each week.

With Credits in short supply in the bloated intergalactic economy, maxing out your friend support bonuses can be a great source of weekly income. Here are some of the best support characters you can share with others in Honkai: Star Rail.

I chose the characters below based on how likely they are to be picked by others. You generally want to stay away from free-to-play units, as most players already have those. Using the characters below isn't enough either: make sure they're built well!

Bronya has been a universally excellent support unit since launch due to her unique ability to buff allies and Advance Forward. Since she is a standard banner five-star character, there are not many players who have her, so she will be picked quite often if you set her up as a support character.
