Ok, so:
I'm lvl 112 and want to keep dropping some rare items (105 rares) from Reanimated Masters, but it's gray to me. Will 105 rares drop to me?

I already dropped Guardian Formation, Crushing Fist and RJ from them but idk how will it be with 105 rares?

Aslong as they still give drops i think its possible that you get them rares, assuming that Reanimated masters drop R105 o.o

It will drop rares until it drops to You anything.
