"Rainbow sand," Brilliance agrees. "Pretty cool, huh?"

"Very. Glass next? Long-form incantation for that too? We're not shy on mana sorting that much sand, are we?"

"Go for it! We've got plenty."

Bella focuses on a circle of some of the green sand right in front of her. "Melt and become clear glass without getting hot," she orders it.

The sand glows and runs together into a perfectly circular puddle, then cools.

"Neat." She points Brilliance at some blue sand. "Melt smoothly together without heat!"

There's more responsiveness in a long-form spell; it gives her feedback about the successful melting-together of the sand. And this one, thanks to the temperature, doesn't end up with extra grains stuck all over it.

She picks up her blue glass circle. "Neat," she laughs. "All right, maybe I can get one clear, stained glass -" She aims at purple sand. "Melt smoothly together without heat transparently!"

It's hard to tell with all the discs just lying there, but the purple one definitely looks flatter and smoother and with fewer impurities than the other two.

Bella tucks Brilliance under her arm and picks up the blue and purple disks and compares them.

The purple one definitely has fewer flaws and impurities. Not none, but fewer.

Hmm. She sets them down and makes a red one with the same incantation as the purple, focusing on smoothness and clarity while she speaks the sentence.

There is still feedback from the spell, silently showing/feeling how the sand comes together into glass. It goes even better this time.

"So there's - either a practice effect, or a focus component that itself has a practice effect," Bella says.

"Yeah," says Brilliance. "I think you've got saying the spell down right, but you're letting up a little when you do the spell - there's not as much doing with the short-form incantations."

"So - I need to pay more attention, basically, not just let it go be a spell?"

"Yeah," he says. "You can feel the details happening, right? Those are yours, you're doing that. You have to kind of... work with it."

"Okay." She aims him at the orange section, and repeats herself, and pays attention.

Under her direction, the glass forms up into crystalline clarity.

"Excellent. This is fun," Bella says gleefully. She hops up and down twice before slipping and nearly thwacking herself in the face with Brilliance on the way down; she catches herself in flight halfway down and hovers in an awkward position. "Whoops."

Brilliance laughs. "Try not to hurt yourself," he advises kindly.

"Occupational hazard of being me. Maybe I should invent a spell for that."

"Hey, didn't I say I'd do that?" he muses. "One to make moving around as easy as flying?"
