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.
Clashing gears and foul magic grind away within this cursed construct. Its malevolent passage can only be unleashed inside a house of the damned.
- Odeg the Keywarden in Act I - Fields of Misery (Infernal Machine of Bones)
- Sokahr the Keywarden in Act II - Dahlgur Oasis (Infernal Machine of Gluttony)
- Xah'Rith the Keywarden in Act III - Stonefort (Infernal Machine of War)
- Nekarat the Keywarden in Act IV, Gardens of Hope Second Tier (Infernal Machine of Evil)
The devices are account bound.
Drop chances increase with difficulty: up to 50% at T6 and 70% at T10.
After the machines have been collected (it is advised to collect at least 3, or 4 different ones at level 70), they can only be activated in a cellar in New Tristram known as the Heretic's Abode. Activating the device will create a red portal which leads to a realm where a pair of Über Bosses must be defeated for a chance to drop one of three organs. Activating the device will also destroy it, so the player will need to kill Keywardens again to get another one.
Upon entering the portal, characters will be transported to one of three randomly selected Realms of Pure Evil, where a predetermined pair of bosses awaits: King Leoric and Maghda in the Royal Crypts, Ghom and Rakanoth in the Larder, or Siegebreaker and Zoltun Kulle in the Edge of the Abyss. On level 70, there is a fourth portal, where you will fight Shadow of Diablo in the Realm of Terror. You may only activate the device on Torment I difficulty or higher.On level 60, each device opens a random portal, but if you activate three devices in one game, you are guaranteed to receive one portal of each type. On level 70, each type of the device will always open a specific portal: Bones (Leoric + Maghda), Gluttony (Ghom + Rakanoth), War (Kulle + Siegebreaker) or Evil (Shadow of Diablo).
For successfully defeating a boss pair, players will be rewarded with extra items and gold. In addition, they will also have a chance to harvest the crafting ingredients from each of their fallen foes, which can be used to create the Hellfire Ring or the Hellfire Amulet. Crafting ingredients will drop the same for all party members. If one player gets an ingredient, all players do. Drop rate scales with difficulty, up to 100% (PC only) at Torment VI. If difficulty is decreased to Master or lower, the drop rate becomes 0% automatically.
- The Writhing Spine (Leoric's Regret on level 70), which drops from King Leoric or Maghda.
- The Devil's Fang (Vial of Putridness on level 70), which drops from Ghom or Rakanoth.
- The Vengeful Eye (Idol of Terror on level 70), which drops from Siegebreaker or Zoltun Kulle.
- The Heart of Evil, level 70 only, which drops from Shadow of Diablo.
With the three (four for the level 70 variant) pieces mentioned above and 2,000,000 (100,000 for the console, 5,000,000 for the level 70 plans) gold, buy the plan(s) from Squirt the Peddler. A level 10 Jeweler (or Armorer on consoles) can craft the basic Hellfire Ring for a fee of 50,000 gold, while a level 12 Jeweler/Armorer can make the upgraded Hellfire Ring and Hellfire Amulet, for the same fee of 50,000 gold.

Prior to patch 2.3, both 60 and 70 versions of the Machine required a set of keys to craft. To craft the Infernal Machine, players first needed to collect all components from Keywardens.
- The Key of Destruction (Key of Bones on level 70)
- The Key of Hate (Key of Gluttony on level 70)
- The Key of Terror (Key of War on level 70)
- The Blacksmithing Plans (and Key of Evil on level 70)
On consoles, the Key of Evil dropped from either Siegebreaker or Zoltun Kulle when using the Infernal Machine of War.
Devices could then be assembled in town at the Blacksmith. The Blacksmith would need to be level 10 (12 at 70) in order to learn the plans (sold by Squirt the Peddler, or dropped by Odeg the Keywarden), and required 12,000 gold (100,000 on 70) to forge the device in his furnaces.
