"There are invisible venomous snakes. Over there. They don't want to bite people unless someone magics them to bite a specific person but they're really easy to magic to bite a specific person. These are wrong snakes," she asserts.

...optional invisibility is kind of cool, though. And much easier to take than the moths' optional glow. She messes up the reflection of the first snake she tries, but manages to copy everything she wants from the second.

"That sounds very much like something someone invented as an assassination tool which then escaped."

"I don't like the snakes."

But she takes their optional invisibility anyway. Now she too can be optionally invisible.

Kanimir shrugs. "They can't help how they're made. At least if they're out here they're presumably not being used to kill someone."

"I don't like that someone made the snakes," she clarifies.

"Yes, that's entirely reasonable."

"But they have useful magic, anyway."

Hmm, what else can she combine with this optionalness...?

Pretty much anything! The optionalness is very agreeable about being combined with things.

For example, that rodent's metabolism--burns fat and glycogen almost as efficiently and accessibly as glucose. Or that perfectly inoffensive snake's ability to appear to be made solidly of one or more translucent colors. Or that bird's weight reduction (wow that's a large bird). Or that flying reptile's ability to breathe fire. Or that fish's ability to breathe air. Or that lizard's ability to breathe water. Or that bush's ability to grow berries that look like gemstones. Or that fern's tendency to curl harmlessly but startlingly around the ankles of passersby.

Well, then...

She does not want to be a grabby plant, but she kind of likes the idea of breathing water. She will take one breathing water and one weight reduction (perhaps it will be useful later if she acquires the ability to fly), and she will optionalize them both, and then she will be out of available Optional Snakes.

"There are a lot of magic things here. It is good."

"I can't get nearly as much use out of them, but I'm glad you can."

"They're really interesting."

Things! More things! So many things!

The grass: is incredibly green! Various flowers also have incredibly vivid shades magically written into them. One species of tree is very, very hard to break. That tree has leaves that chime like glass when rustled by the wind (it is not currently windy). That round foxish raccoonish thing can project an illusion of a much larger version of itself as a self-defense measure, has a tendency to imprint on small children and be loyal pets, and incredibly sleek, soft fur. Sleeker and softer than a unicorns, though not as shiny. That catlike thing over there has biologically-improbably-large retractable claws.

...Riya thinks she will copy some of that extreme sleekness and softness for herself. Yoink.

She kind of likes the idea of being magically durable, but she can't quite figure out how to make it fit. Ponder fiddle ponder.

Well, the kind of durable that it is would probably go best on her bones.

Yes... hmm. She fiddles with it a little bit more. Now she has durable bones. If she wants the rest of her to be durable she will need a different source item.

Durable might or might not be the best word, but that frog over there has enough elasticity and firmness in their soft tissues that things like hard impacts are less likely to do damage.

Hmm... she considers this option for a while, poking at the reflection of the frog. Are there going to be side effects if she just takes it? She should figure that out.

Well, if someone pokes her or squeezes her arm or something it might make her feel weird. ...Might feel a little weird just from the inside.

Yes. She might not like that. Perhaps she will not copy the frog.

Oh hey what's that large extremely magic bird that just entered her range?

Well, if it suffers lethal damage it'll go up in flames and regenerate is what it is.

"Oh! A phoenix!"

"Where?"

She points in its direction, though it is not currently visible. "That way. I like it. I want to copy its magic."

Now, can she copy its magic with only one phoenix to go on...? One way to find out.

It is possible she will screw up. If she does, she can just ask to be teleported away and back.

That turns out to happen.

"I messed up the reflection again. Can we go away and come back so I can try again?"
