[@Ghost Queen] For most mages, that's true, with probably 90% of mages having enough power or less than what you'd need to destroy a building through brute force. Sometimes, you'll get a lucky mage who can collapse multiple buildings, heading up to more than one street's worth of buildings per "full charge", though that's starting to get into "you're likely to inconvenience yourself to some extent to do this" territory. And that goes up the scale, until you get the prodigies who can at full power nuke cities, though they'll probably nuke themselves in doing so, never mind the efficiency limitations for more practical uses of that much power. And don't worry, your questions are fine. I encourage them.
