See the [[Infernal Machine]] article for full details on how to obtain keys, create Infernal Machines, open the portals to the Ubers, obtain Demonic Organs, and use those to craft a [[Hellfire Ring]]. The process is roughly the same in Diablo 3 and Reaper of Souls, though RoS adds a 4th Uber and a 4th Demonic Organ.
