Should be the same result with j.214C, and in the case where I am wrong, then I am unsure as to why it does not work. No way of me testing to see if it is the same case, but try it.
Y'know I was surprised that combo worked, and I simply thought it was only due to the 623A P1 buff. Thanks for finding out that other factor TGR.
Also, in terms of character specificness, it looks like it may not work on those with smaller hitboxes such as Platinum and Noel, but again I have no way of testing this out right now. It does depend on your execution, because you have to be pretty swift with the IAD j.C.
