Gesture Required Ahead
Get on that hook
From my testing, D2, B3, Ji3, 1, 323, 12 xx Flip is the most damage I can muster.
Not sure, but I believe taking off the 1 after Aerial 3 would do 1% more damage. 'cause of the scaling and all. But like Axel_Redd I can't get the B3 off a grounded D2. I can't even constantly get Aerial 1/2 or St1 off of it so I just go straight to 323 , F23 x Sword Flip.
