You're not the only one with a story to tell in Genshin Impact, and in fact some other characters you team up with may have more depth and characterization than you first realize. The writers put a lot of work into making all the party members you recruit have strong backstories and motivations, but they won't just spout it all at you in a boring exposition dump. If you want to learn everything there is to know about your companions, you'll need to raise their friendship levels to unlock more and more of their history. Here's how friendship levels work and the ways you can raise them in Genshin Impact.
How To Raise Friendship Levels In Genshin Impact
Friendship levels are earned, appropriately enough, by earning companionship experience. Earn enough companionship experience with a character and their friendship level will go up. There are several ways to go about earning companionship XP, but before you can start grinding you'll need to bring your Adventure Rank up at least to the point where you've unlocked Daily Commissions.
By completion either Daily Commissions, dungeons, or random events that appear across the map, you will earn some companionship XP. These points, again, are used to level up your relationship with all the companions in your party. If you're unsure if a quest or activity is going to reward you with any companionship XP you can always review it in your menu to check the rewards.
Because each character has their own friendship levels, you will end up having to run dungeons and Commissions quite a few times if you want to max out every character in your party. Aside from just getting to know all your party members a little better, there are other reasons to build up these levels early on. The developers have shared that the system was created to make players care more about the characters you were fighting alongside in the game, but also have you make important choices with them during quests. While nothing like that is in the game right now, it is very possible for these features to be added soon, so getting those levels early might just end up paying off.
