Wizardry is all about thinking ahead, about being prepared. Wizards aren't really superhuman. We just have a leg up on seeing things more clearly than other people, and being able to use the extra information we have for our benefit. Hell, the word wizard comes from the same root as wise. We know things. We aren't any stronger or faster than anyone else. We don't even have all that much more going in the mental department. But we're god-awful sneaky, and if we get the chance to get set for something, we can do some impressive things.
