He can provide a picture. And then blink when it works, which he had not been expecting in the slightest.

"You will be one of the richest women in the world if you find a way around your power's restrictions."

"Good luck, my planet's had magical girls for hundreds of years and the rule on removing magically conjured stuff is no grow no go."

She already knows how to use her shapeshifting to make tremendous amounts of money via growing. Other uses for it - he assumes that she's already thought of modeling, since this is a planet where she isn't competing with other magical girls, and, indeed, very few shapeshifters at all?

"Magical girls do do that at home. It doesn't interest me as a main line but if there's some kind of career agency that'll let me know if a billion dollars are up for grabs I'd look at it."

"I think I can get you on some lists. Do you want to try increasing your strength with shapeshifting, or are you worried about that pushing it?"

"I don't think that'd push it too bad and if you ask for something that's definitely not worse than borderline I can take a wing off."

He nods. If she tries to become stronger - and focuses on the fact, which is very true, that her wing muscles are very strong because they're lifting her - can she obtain super-strength?

She can embuffen her arms - she's normally going for a willowier look - and then she is stronger, though they are not more impressive than if she went to the gym a lot for months and maybe indulged in a little T.

But that is just being stronger. She's not being super-strong in her arms, even though she is super-strong in her wings.

... Are her wings actually outputting enough force to move her, or are they somehow making her super-light via magic? There's high enough ceilings, and he has fancy enough testing pads for her to stand on, to see if the force outputted when she takes off is more or less than the amount it would take to move an object of her mass.

She will stand on the pad and flap across the room.

... Okay, no, these readouts are impossible.

"This machine thinks you can't fly." She is not, in fact, outputting enough force to fly. The computer says so. It thinks the fact that she is no longer standing on it is apparently a coincidence!

"It.... is mistaken," she says, landing and folding her wings once she has her balance.

"Apparently it is." She just has the power to fly when she can't fly. But only with wings. "... To clarify, you can't fly without wings?"

"No. I mean, I guess I could conjure a ladder and stop it in place and climb it, but no."

Powers testers are not supposed to say 'weird'. But for the life of him, he can't think of anything better to do. 

... He can test if she can still fly if she's lifting some mid-sized weights?

She can carry about fifty pounds in the air.

... He's not actually sure what that means but it's good to know???

Okay. Other testing, this time moving to the clothing conjuration. Can she control the clothing she's wearing - for instance, if there's any tassels or cords on her clothing, manipulate them via shapeshifting?

Kinda! If she wants to, say, make a bit of her sash wrap around a nearby object she can do that with some trial and error (she can't see the object in starscape and must make all changes in starscape).

Aha. So that's a real limitation. Does starscape also cut off her other senses?

"No, I can still hear and whatnot normally."

"Understood."

Next step, things technically part of her clothing! Can she create objects "as part of her clothing" that are halfway across the room from her and connected to her outfit by very thin threads?

Looks like she runs into a problem when she can't see the threads or when they're far enough away that she can't see them in starscape. (She can create connected things close to her and then move away from them while the thread unspools and they stay, though.)

That is still pretty great. If he takes the objects upstairs, do they disappear after a while?

Looks like they maybe disappear at the point where she wouldn't be able to tell if they were still attached, should she look - maintaining tension on the thread helps a little but not indefinitely.

Hmm. If the thread goes around the corner of a sheet of opaque plastic, does that make the objects disappear?
