I have had her in my party again for a bit recently and it has made me painfully aware how much the game tries to shove her into the spotlight. She is the only character everyone expresses concern for, she gets a lot of little moments to make you feel for her, she gets dramatic or likability moments at the expense of other characters and she's even got the specially modified romance scenes. If there is any character in this game who does not need any more attention, it's Karlach. If that whole journey to acceptance turns into content that allows poor Wyll to properly shine, I am all for it though. The boy needs some love and some stuff to do.
Besides, the want to live is part of every character's heap of troubles in this game, even excluding the tadpoles for some. But at some point the basic question of survival changes into an exploration of what a liveable life looks like usually by putting previously held believes or wishes to the test. Following your story, Karlach's conflict is just a second "Find a cure" quest, nothing about her perception of the world gets drastically challenged in any way. The only thing she might learn is, that Hell does not necessarily mean to be alone - which could tie in nicely into "after all what is Hell without Hope" if you want to give it a super nice evil twist.
wyl does need help i'm not gonna argue with that but how are you gonna say karlachs story as it sits right now essentially being find 2 scraps of metal and kill her former boss a good amount for her? like kole said those little likable moments are all she really gets in the game since they planned so little around her as we now see. Karlach needs to get something more, avernus forge style fix or finishing act 3 and letting us do it there because i honestly think larian just lied in the IGN interview.
That being said kole is right in that Larian didnt have to give us anything but to think theyd make her story end on her burning up to death on some random dock alone and that be her proper ending[since thats what we got at launch before the outcry] is honestly disgusting. im shocked larian didnt think people would be pissed with the original endings and im glad they listened to the community so much. im pretty happy where she is now its hopeful with a real possibility of future DLC taking us to avernus and to the forge.
