Kaede's flying with purpose. He has Information and a little artefact to prove his Information is correct. This will be grand. He's flying and he's grinning and life's (reasonably) good (terms and conditions apply).
"No, the actions themselves have to be completely nonmagical both in execution and detection."
"Is there a limit to how long and involved an incantation can be to get mana cheapness returns?"
"Not exactly a limit; the returns do diminish and approach a certain minimal value, but I don't think they ever actually reach that value—mana's not integers in our system—and most people only write incantations that long and involved academically, they're very impractical."
"Oh, write up an entire book's worth of exacting detail, title it something unique, incant the title?"
"Not really. The only way the actual informational content of an incantation is used to affect its spell's mana cost is in how 'commonly' it's related to the spell's effect—a fire spell using the word 'fire' in a common language costs less mana than one using 'fire' in a dead language which costs less mana than one using 'fire' in a conlang you invented for yourself, and writing that book would be pretty much the same thing as this last idea."
"That's an interesting question! One I am not sure I can explore until I figure out whether I can learn Draconic at all."
"Hmm... Having a few words would work, I don't actually need to know what the stuff I'm saying means."
"So that might be worth trying, but maybe don't do anything that costs mana till we have a list and can prioritize."
"I can actually figure out the exact mana cost before casting a spell, as soon as I bind it."
"Nope. Well, it doesn't cost me anything, an unassisted arcanist would be stuck with that binding forever so they tend to be more careful with them."
"I usually keep myself well stocked with mana when I can, so it shouldn't be a problem anytime soon anyway, but yeah." Pause. "Also what time is it, should I maybe be leaving you to sleep...?"
"Okay, so I guess I'll go. Oh, also, I meant to ask, are you single and slash or polyamorous?"
"Okay! Wanna go out with me sometime? Not sure how the whole thing works here in Elcenia but I'm sure I can figure it out."
