You best think twice before you toss a coin to any caster. The bad ones ain't worth a dime. The good ones may tell you something you just as soon not know. Changing This talent is about the most common there is, which still don't make it very common. Changers are those what an make themselves look like other people, or animals, or even conjurations.
Most changers can only change to one other shape, a few can handle a fair variety.
Even if their talent doesn't always deal them the top hand in a fight, most changers can swallow a bullet and keep going. It don't take more than that to lick a man without talent. That might be the truth, because chattering is about as tough a talent as you're like to run into. Oh, there are some whose chattering don't amount to much more than a mad man's raving. For a top rail chatterer, almost anything is possible.
