Would Sora regaining his ability to summon/banish and use his keyblade be considered a Moderate or Maximum power? Some information, in case it's needed. As far as I can tell, it seems accurate and up to date with the canon point I pulled Sora from. (Post-Dream Drop Distance.) But it's also kind of long so if you want me to sum up or have specific questions I will do my best to comply.

My first/immediate assumption would be Moderate but obviously this is your call!
