Takeover Souls

This is another one of my non needed ideas, but something that'd be cool. Every single type of magic has some sort of cool item they can buy for their magic from IoTM except for takeover magics(caster magics too, but those are based on using the user as the source). Holder and requip magics can buy weapons, items, and armors that can be added into their magic, celestial summoners can buy keys, and bond users can buy pets. So, I was thinking that takeover magics could have an item for themselves called souls. This would mostly be for item of the month stuff, but the souls could be sort of like summoning Keys, in which the soul you are taking over has a unique story and look to them. Though, instead of the soul having all the partial takeovers in the buying, it will only have the full takeover and the actives for it. Then, the person can add their own spell slots into that takeover once they buy it. Although its not needed, I feel like it'd be a cool addition to the IoTM's, and takeover's in general.

Not a bad idea, but overall to specific and clunky to work around and implement. We talked about this and decided not to implement a system of this kind in the foreseeable future, at least not in this particular form. As such, I will be closing this and moving it to denied suggestions.
