Jack's powers will be acting up, so potential for freezing oops there! If not people than objects that he goes to pick up. I'm mean so I'd kind of like him to have a close call with a person though, so if anyone wants to get very nearly bad frostbitten, that's cool. get it He will be really surprised to find he's basically put back to normal for the last two days, and it'll be bittersweet. Really tempted to have him revert to his original colouring, y/n?

River will quite enjoy being normal, even though her abilities are medically enhanced instead of magic, it's good enough to squeeze in. Now some of hers are physical conditioning and that will stay, less stimuli might mean more stable??

Bakura will definitely not be able to summon anything reliably, and then not at all. He also won't be able to use the Ring for anything. people with grudges take note He will still be able to communicate with his ghosts though 'cause I'm not that awful today.
