"I'll keep working on it. Not right now, but when I'm stronger."

"Is that how that works?"

"Is what how it works?"

"You get stronger?"

"...Yes. Do wizards not?"

"No."

"So you're just stuck at the same level forever? That sounds frustrating."

"We can learn and invent more spells but our channeling capacities don't change."

"What's the correlation between spell efficacy and power level?"

"...what do you mean?"

"Like, what traits in spells make them require higher channeling capacity to cast?"

"Anything transworld, adding a lot of passengers or other extensible features to things that have those, generally being complicated or affecting a lot of things."

"So it's more about complexity than power?"

"Well, small spells also aren't very powerful..."

"So--if you want to do something, but don't have enough channeling capacity for it, can you invent a more efficient spell to do the same thing?"

"Sometimes."

"When?

"...if you can fit all the things the spell needs to do in less pull."

"But there's no way to, I don't know, shunt pull requirements into increased casting requirements?"

"You can sort of do that with diagrams."

"Can you gain ultimate cosmic power with good enough diagrams?"

"If there is a given really difficult thing that you really want to do, is the limitation on most people not being able to do it that they're not good enough at diagrams or that it just can't be done?"

"The second thing, I think."

"Okay, I think I like my magic system better."
