That's why I say it's not likely they'll just patch some quick fix with Dammon, Gondians or whoever. If the change is coming, they'll likely improve her whole questline so she feels like an actual origin not side character. In short, they'll rewrite her concept
Tbh, I'd love that, as her content now is barebones. At times, she does give me the 'npc' companion feeling than an actual origin character which is sad. If Larian didn't manage to get her story whole due to time, then all the more reason to add more content now that the game is out.
Yea it would make sense if they want to add something large for karlach to get you up to scale with the other origin characters. I'm here for it as long as we are gonna get it but as others said larians history of not talking about anything is good for business bad for us. I just hope they give some small post on insta or Twitter that says yes we are giving karlach more content and a happy ending. I know it won't happen but I'd be really nice to see.
