So as a spoiler but have to say...

From what i read in the patchnotes Karlach just got extra steps to her bad endings. She litearlly is the most good Character in this game and just deserves a good ending. Just give another upgrade , reuse the animations and DONT blow her up at the end... She can life with the character nice and happy. I mean i got 4 more metal for her its not really hard to get.... Please larian... don't give me the cyberpunkt ending style where evertything is loosing...
