If you don't have a mod for many character traits, then you've probably already encountered the problem of not having enough space for the traits you planned. I would like to assign them to the character, but I have to choose between them, since space is limited.

As you already understood from the name of the mod, all in-game character traits will be rewarded! To do this, you need to select the one you need and install it into the game (in the mods folder). Now it will become a reward and will not take up an extra slot.
