Works the same in v1.21, but with less damage on spirit bomb. Only use if you have excess meter but not assists to kill a character, as the spirit bomb no longer causes hard knockdown either.
(notation for reverse kame + spirit bomb is as if you never changed sides, for more clarity)
Very common corner route for using an assist to combo into 5 L L L -> reverse kamehameha -> spirit bomb. Reverse kamehameha routes that end low to the ground make these easier, and are required for some assists.
