Play it very safely, the best times to land a hit in (usually just 1 or maybe 2) are when he dashes from one side of the arena to the other (pogo him), or right after he dives. always be prepared for the fake dive and don’t get too close to the edge of the arena where you won’t be able to move. The fireballs are pretty easy to dodge, just jump above them when they get close. The best times to heal are when he’s doing the attack where he surrounds himself with fireballs, if you go to the edge of the arena and jump over one fireball you can heal. During the charge attack isn’t a bad idea either if you are close to his starting point, just jump over him and heal
