I'm asking for a spoiler here. I 've been trying to save Minsc from the absolute, but I'm not sure if it is possible at all.

I got to the cistern and thought that if I could keep Minsc alive and kill the dopplegangers and the rest of the Bhaalists, he would realize that he was fooled. But that doesn't seem to happen. I did manage to kill every enemy except Minsc, but he keeps fighting. Cast a "domination" spell on him, which entirely stopped the battle. But when the domination runs out, a new battle starts with only Minsc against us.

So Jaheira leapt to her death in true kamikaze style at Moonrise towers. Does it make sense to continue to try to befriend Minsc or is it impossible without Jaheira ?
Thanks for your insight.
