Question: diablo 3 what is infernal machine?
Answer: The Infernal Machine is a device in Diablo III used to open a portal analogous to the Über Tristram event in Diablo II. Once inside, the player can battle two Über versions of Act Uniques for an opportunity to collect organs to create a Hellfire Ring or (as of Patch 2.1) a Hellfire Amulet.
