Cam is dipping a grilled cheese sandwich into a bowl of tomato soup when he feels the summons. He goes ahead and grabs it. Doesn't even drop the sandwich.
"So I'd better not go with anything somebody would want to steal, either, no getting fancy with an opal in the middle of a diamond or whatever. It has to be the exact individual object, one exactly alike down to the atomic level won't do?"
Lioncourt shrugs. "No-one's ever tried the latter. I would stick with the proven method."
"Cool." Cam opens his hand and produces therein an egg-shaped banded agate in various shades of blue. "Like so?"
"It's very pretty, but I'm not sure you want something quite so polished. If you drop your agate and it breaks..."
"It might scratch, I wouldn't expect it to break. If scratches are an issue I could put it in a thin layer of diamond, too small to see. ...What does polishing have to do with breakage?"
"Not much, but it is likely to make your rock more slippery. A scratch wouldn't be a disaster, but if it was at all significant it might set you back a few days as you reacclimated."
She tilts her head.
"... I would hesitate to be too optimistic, but working with an ideally suited tool like this might actually cut a week or two from the time necessary for proper ritualization."
"Really? How? It's not more of a rock than anything you'd pick up off the ground, it's just a little sturdier and pretty."
"Yes, but that increase in durability means that you won't have to compensate for everyday wear and tear. Degradation of tools slows the learning process, since you have to adjust your motion, even if it is by the tiniest of amounts."
She smirks.
"I somehow doubt it, though."
"It probably won't help that I'm a very clumsy person. Though mostly for balance and not manual dexterity, I can play the violin just fine."
"That is the standard first exercise, since it will give you the range of motion from your feet to where you hold the rock steady. At least, in the vertical direction. Others might be possible, but will give you even less useful parlor tricks than 'pick up things that weigh less than a rock from the ground.'"
"I'll want to set aside a ritual room with a mark for you to place the stone into, and marks for you to place your feet into. The room is otherwise unimportant, but I personally find that it helps my concentration if I make the room aesthetically pleasing."
