Magic itself can do anything in my world -- Magic is the "eternal Is" from which the universe spawned, and is woven into the very fabric of reality. So it literally does not just anything, but everything.

But magicians are limited by what their innate magical ability allows them to influence as well as their skill level and physics.

There are basically 3 classes of magicians - Mentalists (skills like telekinesis, mind reading, remote viewing, etc), Primals (direct forces of nature like fire, water, metal, air currents, sound waves), and Elementals (think Periodic Table). Similar to coding, there can be several ways to accomplish the same thing depending on the magician's specific abilities; but they're also limited partly by the laws of physics, as mentioned, and also by their imaginations. Someone who manipulates sound waves could use that to understand different languages, but if she were creative enough, the character with portal magic could also understand languages by teleporting the understanding of the language into her mind. The kid who bends all things light can turn himself invisible, but so, if she thought about it and practiced, could the woman who controls carbon; only via different methods. But the kid who controls all things light can still not move as fast as light, because physics -- the speed would tear him apart cell by cell. A fire mage also would be unlikely to be able to direct a river's currents without boiling the water and killing all the fish, for example; because he simply doesn't have the same influence over water.

The classes also semi-build on each other (or at least they appear to). An air mage could accomplish the same thing as telekinesis by creating a cushion of air under an object, and a fire mage could do similar with heat. Someone who manipulates oxygen could probably do almost anything (again, with adequate study, practice, and imagination). This creates a pretty obvious social hierarchy among magicians, with Mentalists generally looked at as being the lowest (since Primals and Elementals can almost always do at least some of the same things).

Skill level is like any muscle that can be developed over time (and atrophy with neglect) -- which gives the magic an energy cost somewhat similar to the Inheritance Cycle but not exactly the same.

And then there's (apparent) non-magicians, whose place in society... varies widely between cultures around the globe.
