Yep! And if not she can spend a modicum of mana to create elementalist blessings for each of them for a few seconds—

And then she can be invisible and insubstantial and telekinetic and elementalish.

Eeeeeeee (good thing all these blessings activate at will).

"So," she says conversationally, "how do you feel about being able to control the other elements?"

"...what do you mean?"

"Earth, fire, water, and air."

"That would be weird but sure!"

She floats over to Ruava and boops her on the nose. "That was completely unnecessary but I liked it anyway."

Giggle.

"Also you can now turn invisible and insubstantial at will, and are telekinetic."

"...and how do I operate all these shiny new powers?"

"Right, okay, so—invisibility and insubstantiality are fairly straightforward, the mental action needed to activate them isn't just wanting it but it's similar—here—" She sends a mental impression of what it feels like. "They're both very well-behaved, I designed them myself and you won't, like, accidentally go through the floor without meaning to or become stuck in a thick wall or suffocate or go blind or anything—come to think of it I'm not totally sure how it'll behave without the mana cost—"

"...and what exactly about it are you not totally sure of?"

"Well, invisibility's pretty okay regardless. The way the elementalist blessing for insubstantiality works, though, is that it costs a certain amount of mana to go through a wall and it also costs mana to breathe in it, and if you run out you're stuck and die. The spell, though, merely has a time limit during which you can go through any solid objects you want to, bringing whatever's on you with. When it's close enough to the time limit that you need to start worrying about stopping intersecting the object, it gives you a mental warning that gets more urgent the lower your margin of safety is. If you try to go through anything you would be unable to stop going through before the spell ran out, it doesn't let you."

"That sounds like not having a mana cost will just make it... work? Unless the mana cost ends up substituted with something else somehow? When people have blessings that let them do stuff, a lot of the time it's tiring to do the stuff. Not hugely, but some."

"That depends on whether it'll work like the blessing or the spell. I switched a couple of blessings just to check but I was trying to go for the spell. Now, the blessing versions of controlling the elements and telekinesis spend mana with time and scope—like, you can generate fire but the more fire you generate or the longer you keep it up the more mana that consumes, the more finely you control the air the more mana-intensive that is, etc. The spell versions have a limited duration and a maximum scope."
