Using your shield against projectiles right when an attack's hitbox is about to connect will reflect the projectile in the opposite direction, dealing 50% damage and knockback

Roy is the weak version of Marth. Like Marth, his sword contains different hitboxes depending on where your opponent is hit (hilt = strong hit, middle = regular hit, tip = weak hit). Roy is EXTREMELY hard to hit during his up-b animation, but because of his fast falling speed and bad aerial mobility, his recovery is generally very bad.
