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.
Yeah it seems super buggy. I had her in my party the whole time, did her quest etc, but she didn’t offer any help. Didn’t think anything of it until I reloaded the save to see some more endings, and all of a sudden she’s like “have some harpers!”
What’s weird is that I still had her harpers for the fight. I guess because she offered them right before telling me she hates me. It was a strange scene for sure. Anyways, I just beat the game. It’s an amazing game, the best I’ve ever played.
