And when Lúthien's translated that -
Okay. Making a wish alone won't do anything except mean that you can't make any more wishes, but doing the whole magic package thing involves some stuff, which I don't consider likely to be a dealbreaker but somebody might and which you should know about in advance anyway. I am technically not inhabiting my body; I'm this rock, she taps the back of her hand, operating my body by remote control, range limit a hundred meters. This costs magic to do and it's the only magic cost you can't stop paying unless you want to just be a rock without a body, which is pretty unpleasantly sensory-deprivationy. Amount of magic is signified by brightness of gem. It's a ratchet on emotional state; you can't get happier than your gem is bright - the gem will also dim if you get upset. I am unusually good at working around that and avoiding depressive spirals when I get low. The infinite energy hack is a happiness song of which I have a recording I can provide you a copy of, charges us right back up, obvious side effects are obvious. With the version I'm offering, which is better than the one I got, running entirely out of magic will leave you unable to operate your body until you're recharged and you will have the obvious happiness ratchet problem; I don't know whether an uncharged soul gem can still hear-for-magical-purposes through its body's ears if the body still exists to do that with, probably not, but somebody can donate charge to you from their own soul gem if this happens. Magic is quite intuitive to do but gem dimming is not intuitive to track and if you're trying to do anything with magic that isn't on the standard everyone-can-do-this list or one of your theme thingies you should be prepared for it to be unexpectedly expensive. For some reason the entire process comes with a costume change - out of costume the soul gem is a ring, in either form it can adopt a bauble shape, in costume it defaults to being on the costume somewhere. It breaks, you die. It does require considerable concentrated force to break one. Costume'll subconsciously customize somewhat to your tastes but it seems to have a thing for skirts and I don't know how much of that is the thing where in my world it's girls only. Questions?
