Spoilers for the end of act 3 below.
Idk what happened. I’ve only ever helped her. We just came from the astral plane and are ready to fight the brain. She pledged her sword and I gave a speech saying everyone is the hero of Baldur’s Gate or some such, and then it cut to her telling me off and telling me if I die against the absolute it’s better than I deserve and she left. WTF? Does anyone know why that happened?
Edit: mystery solved. More spoilers below.
If you kill Minsc instead of saving him, and then don’t talk to Jahiera before the battle, she finds out about it after your speech, is hella pissed, tells you off, and leaves. She already pledged her harpers though, so you still get to use them.
Gale shat on me for taking Raphael’s deal.
I did not even speak to Raphael.
Probably a game oopsie
That kind of sucks. I’ve intentionally kept her around so that she would be useful in this last fight. Oh well. I think I’m almost to the brain and I haven’t had to call on reinforcements yet.
I was reading that they fixed this in a recent patch. It also happened to me.
