The timing on the hj.B must be SUPER tight below, say, green, then, because I can't seem to connect it and I've tried different variations of that combo for a few hours. I guess I was more concerned with finding combos for Grey and Blue levels as damage sources after a D Beast. Funny enough, I have absolutely no problems comboing into C Beast with that combo (sans the extra j.b)
Durr I have no idea why I didn't think of that. Thanks.
