Seriously? Is there a setting or something I'm missing? After one of my first fights in the caves underneath Cyseal, I had to heal my entire party after running right through the fire I had made on the ground.
That's the point! The characters behave normally at the adventure mode, but they will go mad and ignore all the adverse conditions everytime after a fight.
So at this time, we have to stand by for further heal spells. It's a little bit annoying, right?
