Disguising oneself

You cannot make a deer look like a fox - that's just not how it works (normally). In this game, disguise kits are magic items that have something not unlike makeup, but with Illusory effects. Someone who is proficient in this manner of work (or just manages to work it out) knows what to apply, and where, to create the desired effect. The disguise kit cannot make you seem larger or smaller, and it cannot change any aspect of you that is not visible. It also has no effect on nonliving things.
