Can you create custom hirelings to recruit as companions? Or customize the pre-made ones (beyond class re-specification)?
I don't think it is possible through the vanilla game. Are there any mods which will let me do this?
I think I heard something about Larian Studios releasing example mods for how to create hirelings, but there's no workshop support for BG3 on Steam as of yet, so if such mods exist, I wouldn't know where to find them.
