Feel 100% free to write one now if you prefer. I'm going to paste them on the first page of the OOC anyway. Much more convenient than links, I think, so long as there are hiders.

Oh, and as to that talk about turning something into a dog, I just remembered I didn't address that. As it says up there, a wizard could theoretically do anything, but in reality their powers are very limited. Turning a human into a dog, for example, would involve describing all the internal workings and the exact appearance of a human, all the internal workings and exact appearance of a dog, as well as the process whereby one turns into the other. It's questionable whether all the magical terms involved are even known to all the wizards in the world, collectively, and there is certainly not a single wizard who could speak them all without stopping to draw breath. In fact, it would be a lot easier to turn a human into, say, gold, since that only involves a single kind of atom in the latter part of the spell. Still basically impossible, though.

Not that you need to be a chemist to play a wizard. A passing familiarity with high school science should be more than enough - just fill the blanks in with pulp. Just remember that the more complex and powerful a substance, reaction, item, etc is, the more words it takes to describe. A skilled enough wizard might be able to turn a human into what looks like a dog through a series of thousands of small changes, each sustainable (if unspeakably agonizing to live through) on its own, but if you cut that creature open, it probably wouldn't look like a dog on the inside. Kind of like that movie, Walrus, but with magic.
