I went the route of choosing to side with Orpheus, but noticed his hit points were oddly low compared to everyone else. I thought maybe he suffered from the same issue Minsc does and that you just need to change the difficulty level and back again to fix it.
What I did notice was strange. His hit points went up as the difficulty level increased, while the rest of the party's went down. And vice versa, his went down as the difficulty level got easier while the rest of the party increased.
Is this a glitch or is it supposed to be that way? One would think his hit points should be higher on easier levels.
