I've only really had one chance to fight against Balthazar in the snow. It didn't work out to his advantage, let me tell you that. I was able to form snowballs while Jolie used her wind magic to pelt creature after creature, giving Nikko and Summer the opportunity to easily move in and destroy a bunch of goblins and skeletons. I was also able to will the snow to freeze even more, becoming slick sheets of ice that rendered Balthazar's minions completely useless. And I was able to do all of that without having to expend much of my spark.
So, while it may not seem like much, snow can definitely be used to my advantage. I'm pretty sure Balthazar learned that a snowy battlefield was never going to lead to anything but defeat for him. I guess perhaps that's why he's avoided battles in the snow since then.
