To the best of my knowledge, in a Gold Box game, you need to exit the game and start it up again to load a game. It's kind of shit. I think they are trying to encourage you not to save scum your way through the game, since restarting the entire game is such a hassle.
Yeah I realised this later thank you. You seem to know your way around was wondering what I'm missing with combat extra options, ie: when I enable quick mode I see them sweeping and attacking multiple times but I cant get them to do it in aim mode. I should have 2 magic missiles with my mage but he only fires 1 I did 2 damage one time which is impossible at lev 3??
So, to the best of my knowledge, your fighters will sweep when they attack while surrounded by low level creatures. This happens a lot in Pool of Radiance, never seen it in Curse of the Azure Bonds, and that's as far as I've played.
As for Magic MIssile, you won't see extra missiles. You'll just see the damage steadily go up. In Curse, I was routinely seeing Magic Missile hit for 20+ damage towards the end of the game.
