Honkai Star Rail does not feature any co-op but that does not stop you from getting help from other players. There is a Support system in place that allows you to borrow a character from other players to help you clear content. You can also set one character from your roster on your profile that others can borrow. If you do not know how to set support characters in Honkai Star Rail, here’s how you can use it to your advantage.

How to use support characters in Honkai Star Rail
If you want to use other players’ support characters, here’s what you need to do:
Launch any activity that requires Traiblaze Power
On the fourth slot of your party, you can click on the Support button
Choose a character you want to borrow
Complete the activity and repeat it as many times as you want
Do note that not all activities allow you to use support characters. There are no downsides to using support characters and if you do not have access to leveled units, using supports can help a lot. If you are struggling with content even with supports, we recommend focusing on ascending your characters and raising their talent/trace levels.
Remember to claim any credits that you earn from your support units from your Trailblazer profile and if you have a well-built unit that a lot of players borrow, you can get quite a bit of credits for Honkai Star Rail account.
