After watching a couple of Ruco vids it seems painfully obvious now what that ailment is. It's not a thunderblight, it's magnetic attraction/repulsion. The ailment is also indicated with a U-shaped magnet symbol next to the character's names. It allows him to pull you in or push you away whenever he performs certain movements.

It isn't gravity control but this also works.
