I...think I see. So you have to be taught the spell, yes? Like — say, baking a cake. For you, magic needs the recipe and the ingredients already made for you, and following them is what adds the intent.

[if you like that spell so much why don't you MARRY IT]

Or like...sewing. You can make a dress, but you need the pattern pieces, and the materials, and to cut them out properly and stitch them together. You are sewing a spell together, with all of these components.
