The situation is: thirteen magically talented women (one wizard and twelve people with their magical abilities represented as different sponsored magics) get kidnapped one at a time by a seriously overpowered Koschei who is using them as magical batteries that he can draw on. They, naturally, object to this, and end up performing an enormous ritual with the effect of letting all of them draw on each other's magic as well as breaking the links Koschei had to them.
During the fight with Koschei, they have unlimited access to each other's powers, but after the fight, some of the effects of the ritual fade, and while they're still linked, they can only draw on one of each other's powers at a time, and the person who's power they're drawing on has to consent (they have a mental link, so they can talk to each other at a distance--this is mostly only relevant for getting this consent). I'm not sure how to represent this. I was thinking of either giving each of them a -3 refresh "modular magics" power that allowed them to access any one of the sponsored magics and switch them out with an action, or a -2 refresh power that allowed them to access any of the sponsored magics for a fate point. Do you think that either of these would work, and if so which one?
