Hey mowhowkedone remember me we did a trade bout a month back and also ty for the gifts, but anyway I've been to the cow rift I'm not sure how it happened but I can tell you I was in act 1 when I opened it and it was the best rift I've ever played me and my girlfriend found I'd estimate about 15 legendaries ,well I'm rambling but I hoped this helped a Lil.

O and I was playing on ps3

It is random luck i have done over 5000 rifts on 2 account's and only got it 2 times first time was on hardcore expert difficulty in act 5 2nd time i was in a t6 game on core act 1 my mate i play with has done just as manny rifts and still has not spawned 1
