First of all, I'd like to say that this works at 0% too, only if you DI it correctly, by the time bayo finishes you off she'll be so close to the blastzone that the slighest windbox would blow her up to her death.
This can be pretty critical in the matchup, or it can just be a gimmick, but its something worth noticing if a bayo tries to get you in this combo.
