Right now, it consists of Pants, Boots, Helmet and Gloves. All these 4 pieces run in conflict with most sets. Therefore, it is not possible to wear most 6 piece sets with Cain’s Destiny. I suggest to change one of Cain’s piece into a Belt, or Bracer.
Secondly, it only offers 25% chance for another Rift Key stone to drop… This is very low chance. At T16 this only translates into a 4.3 average key stones per rift run from a 3.5 average without it. 0.8 increase, is kinda low considering we’d be using suboptimal builds to run T16s. I suggest to increase the chance to 50%. This will boost the average to 5.25 keys per T16 runs. Simply put: T16 Rift runs are a chore. Might as well just eliminate T16 Rifts and just go directly to GRifts!
Thanks!
