"It does seem useful, if we have a container suitable for an overnight amount of water."

Gem, can she keep this amount of basic machine quality translation but also gain the ability to trade some duration for "footnotes" on anything that is particularly hard to machine-translate?

Sure, that works, Blue says.

(White chimes in that it can help with that, more cheaply! And save a chatlog.)

"I could dump out the whiskey keg?"

Oh it's being helpful! That's so cute. ...how much more cheaply.

"Alcohol has calories in it... but I have no alcohol tolerance and I'm guessing you don't either?"

"Not whiskey. It's really strong."

(Mostly it's that all the gems she's touching react at once when she considers a magic.)

Using, enh, maybe a tenthish of a white gem and 2/3 of the blue will get her the same thing as before, plus historical log and footnotes-style capability for at least a few times a day.

"What's the approximate relative value of these gems, is it just - their rarity, as reflected in the ones that are here, or is it more complicated?"

"I think orange yellow purple and sky-blue are more expensive? I don't think you can just go to the store and buy one. Oh, I remembered sky-blue exists and is different from blue but I don't remember what it does."

"Okay, but if I can do something for less than ten percent of a white one or for about a third of a blue one...?"

"...Probably the white one?"

Nod.

She does not need the chatlog, white gem, but she'll take its footnotes and the blue gem's language assistance.

Once more, the power stretches and twists and flows. Once more the feeling of exercising something immaterial swells. Is it stronger than before? A bit tenser, a bit more strained? Hard to tell.

"I want to go ahead and get the filter magic. But after that we still need to deal with the mountain lion. Also green can help us be okay with less food, or blue can help forage, I know some wild plants, or red make us stronger and faster. But there's still the animal. Unless it went back home..."

"Wasn't the point of getting the gun box open that we can shoot it?"

"Yeah but... Are you sure you can hit it the first time? And you need a way to see it. There wouldn't be time to reload..."

"I'm not positive I can hit an invisible monster, admittedly. I've spent time at a gun range but not a lot of it and the targets were visible."

"Invisibility breaking magic? Or seeing invisible things magic? That's really... Only useful today, though."

"...echolocation?"

"Or maybe living things sense?"

"I'd rather have echolocation personally but if you want to spend the power space on it go for it."

"It was just an idea. You're the one who needs to see it - sense it- And shoot it... I know how to shoot too. Not great but some."

"If you want me to shoot it I'm taking echolocation, yeah."

Blue gem: echolocation? It works like so. Apparently bats do fucking calculus.
