Dragonfire, and your fire spells, can light the scenery aflame. Oil can also be lit on fire.
I couldn't be happier, as I usually play a fire battlemage. But I can't help wondering what other magic<-->environment combinations are planned for skyrim?
Can certain frost spells freeze the ground? Can lightning course through puddles of water, electrocuting everyone standing in it? Will fire melt snow, to a certain extent?
Could a frost mage traverse a lake by freezing the surface as he goes? By the same token, could a fire mage melt a hole in the ice of a frozen lake, dodging just in time to trick a troll into falling in?
Possibilities possiblities. What are your thoughts on this? How likely do you think each of those possibilities are? Do you have any ideas of your own on the matter?
