[@TMS Prime] It would be raw elemental power as I haven't considered the possibility of one-off skills like ice, mist, etc. But I would say it's something that could likely be developed in the story itself. I'm thinking to get those kinds of results, someone would need to know water and wind to make ice. Or someone would need air/wind and fire to get heat through the air. Or maybe some kind of stone is crafted into a device that adjusts the raw power like a scope or filter perhaps. I'd say I'd be pretty open as long as the power's intensity was thoughtful and not overkill. 

Does that help? Probably not. I'm sorry! -cringe- But it's a concept I am open to but since the use of magic wasn't going to be too frequent I didn't want to dive too far down the rabbit hole.
