[Path/Book Magic] Expanding on The Magic of Stories

In several places in the rules, 25 EP is equated to 1 CP. (E.g., Points For Energy in Impulse Buys.) One Use Only is 1/5th cost (not -80%), so 5 EP = 1 CP of single-use Advantage. Gizmo is 5 CP, so putting all those together suggests 25 EP for a ritual that grants a single use of Gizmo.

That's a little high compared to the examples for Energy Accumulating spells -- a factor of two -- but not completely beyond the pale. If it's meant to be used by fairy-tale NPCs as plot points, then the exact cost really doesn't matter.

Other caveats: the 25:1 ratio is a guideline that's worked in practice in several places, not actually a rule or fundamental system design principle. And swapping out magic systems are one area where those sorts of rules of thumb might not port well, so scrutiny is wise. But even if you tweak the ratio, the basic concept might give you a way to price Advantages-as-rituals in general, while remaining at least somewhat consistent with other rules.
