Later today I will toss something out in the bug area, but I do think its how they intended it to be. Even more interesting probably 1/4 of the Yilbegan I have fought have definitely be a HQ fake, and thus were much stronger than their NQ counterparts. Kind of like KS99 can have NQ and HQ versions of the mob. So many time you are all exciting because the VNM is lasting forever and you think maybe this is the one even though it doesn't have a shadow. But nope. In all the black abyssite farming I have done I have gotten many of the T3 rings and all the rings have dropped off NMs with shadows. Just a side note.
