Realized I got a few questions re: magic! 

So I'm going for a more destructive angle with my Battlemage, in a "point her at a direction and it goes boom" sort of way, but unsure what the powerscale for magic like that would be, or how specialized a typical Battlemage is. Like are they more focused on their own niches, or is it typical for a Battlemage to supplement their main focus with other spells (like, say, a d&d wizard)? And if someone's main focus [i]was [/i]to cause destruction, what scale would we be talking? 

I'm cool with anything, just don't wanna take her in a completely different direction than intended!
