This thing that Law is after (S.A.D) was said will be able to shaken up New World just like that, and is powerful enough to be used against a yonko and take him/her down.

If its just something to do with creating artificial DF, it does not sound that great (don't get me mistaken, I agree its good but not great) at all to fit the earlier mentioned descriptions.
