Then you may not want to champion
@Aleph's point because that is the exact point she said.
So if this isn't actually your argument, perhaps don't defend it. She literally says you can not build an artifact that does what the spell does without being able to use the spell. Not "theoretically know how the spell works" or "theoretically be capable of casting the spell" but literally "know the spell". Unless we're using a strange definition of "know the spell" that is different than how every RPG that has ever existed has defined it.
Example, from how I understand this to work:
a) Knowing "Fly" lets you shortcut the process of "Design a plane" (because you have practical knowledge of how magical flight works), and serves as a viable prerequisite for "I can design a plane".
b) If you have a working plane to study or the complete blueprints of a plane, you can use that as a "spellbook" to learn "Fly", because such a thing is definitionally a demonstration of the principles of magical flight.
c) If you want to actually build a plane, you must have a working plane to disassemble so you can copy it or a blueprint of a working plane.
d) If you don't have a plane to copy or the plans for building a plane, you can attempt to invent a working plane from first principles so you can use those plans to build your plane, and knowing "Fly" rather helps you do that, see a).
e) "Fly" needs to be fueled
somehow, whether it's you casting it or the plane "casting" it (because there's no real difference here, "Fly" is being used and "Fly" costs motes), so you need to pay for it yourself or get a hearthstone battery or a bound demon or whatever.
Martial Arts has never worked in three editions of this damn game. Organization management has never worked in three editions of this damn game. Many things have never worked in three editions of this damn game. You can choose to ignore them, if you wish. But if you do you are cutting out a huge segment of the people who play Exalted and why they play Exalted.
Well, I murdered Martial Arts, did I not? Pretty thoroughly. So did you, even if you didn't do it as drastically.
You don't win Exalted, Jon. I want my character to be unique and interesting. This will not be the case if everyone in my Circle has the same magic sword as I do.
You do win
conflicts in Exalted. You do so by leveraging everybody's skills towards a common goal. If you can make lightsabers, and your friend is a swordsman, yes,
by all means, I think you should give him one. This makes it more likely that he lives through the next fight. Which makes it more likely that you live through the next fight. And so on.
And since the system being proposed means that I can only produce Magic Sword X unless I invest in buying Spell Which Is Magic Sword Y Instead then... yeah.
I don't think it requires that, though? At least, not as I understand it. Rather, inventing a magical widget requires you to know how the magic works so you can widgetify said magic. If you have the plans for a working widget or a widget to copy, you don't need it.
Except all of B's noncombat things are stuff that makes him better at combat. Like, according to the
@EarthScorpion and
@Aleph system I don't
have the ability to make flexible downtime stuff, Unless I literally spent my character resources on Spell For X I can not do Magical X. So all those Craft Charms and Spells are only useful for Making Swords.
If spells are cheap, isn't that fine? You can fly with a spell, for example. Nobody else can, unless you build a flight widget for them. Flight widgets need resources to build, which they should be helping you get, fuel to operate, which they should supply themselves, and maintenance to keep going, which they should be compensating you for... all of which you are presumably willing to do because you have shared goals.
So, as you can see, you can not actually make an artifact that costs the spell at not cost to you. He was quite explicit. Having the artifact allows you to cast the spell for the exact same cost; its only utility is allowing people who do not know the spell to cast the spell.
Fair if there really is only one way to pay for it, but I don't think this is the case in what they're doing.
