Ready for a double dose of diabolical danger? In patch 1.0.5, level 60 players will be able to forge a cursed construct called the Infernal Machine, allowing them to battle "uber" versions of some of the most malevolent mischief-makers this side of New Tristram…in pairs. While the rewards for defeating these extra-bad bosses will be great, some assembly is required.
Read on to find out how to craft the Infernal Machine, where it can be used, and what epic rewards await those brave enough to unlock its secrets.
To craft the Infernal Machine, players will first need to collect four components from powerful Keywardens in each Act of Inferno:
- The Key of Destruction will drop from Odeg the Keywarden in Act I - Fields of Misery
- The Key of Hate will drop from Sokahr the Keywarden in Act II - Dahlgur Oasis
- The Key of Terror will drop from Xah'Rith the Keywarden in Act III - Stonefort
- The Blacksmithing Plans will drop from Nekarat the Keywarden in Act IV - Silver Spire Level 1*
(Each component will be considered "Bind on Account," which means they can be used by any character on your Diablo III license.)
Players will be able to encounter the Keywardens in any difficulty, but only in Inferno and with a full five stacks of Nephalem Valor will they have a chance to drop pieces of the Infernal Machine. While Monster Power is not required, each level will increase the drop rate of both the keys and the plans by 10%, all the way up to a guaranteed 100% drop chance at Monster Power 10.
*As of patch 1.0.8, Nekarat the Key Warden now also has a chance to drop a random key.
After all the components have been collected, they can be assembled in town at the Blacksmith. Your Blacksmith will need to be level 10 in order to learn the Legendary plans, and he'll require 12,000 gold to forge the device in his furnaces.
Once crafted, the Infernal Machine will remain in your inventory until activated.
Once assembled, the powers of the Infernal Machine can only be unleashed in one location -- a cellar in New Tristram known simply as the Heretic's Abode. To activate the device, enter the cellar (located just behind Brother Malachi the Healer) and right-click the item in your inventory. This will summon an ominous red portal that will lead you to a demonic realm where you'll be pitted against a pair of Sanctuary's most nefarious villains.
In order to access the Heretic's Abode, players will need to set their quests to "Act I – Return to Tristram."
Activating the Infernal Machine will also destroy it, so to open another portal, you must craft the device anew. This process will include recollecting each of the three wardens' keys as well paying another 12,000 gold to the Blacksmith. (Don't worry about the plans -- once you've trained your Blacksmith, they will remain available in your crafting list for use at any time.)
Those brave enough to step through the Infernal Machine's ominous output will be transported to one of three randomly selected Realms of Pure Evil, where a predetermined pair of bosses awaits:
In the Realm of Discord, King Leoric and Maghda guard the Royal Crypts.
In the Realm of Chaos, Ghom and Rakanoth defend the Larder.
Finally, in the Realm of Turmoil, Siege Breaker and Zoltun Kulle protect the Edge of the Abyss.
In terms of difficulty, the encounters will be about as challenging as the Diablo fight in Inferno, and each "uber" boss will retain their full arsenal of base spells and abilities. Many of the abilities are more powerful, and certain bosses have even come up with new tricks to test those who dare to enter their domain.
If you happen to fall while battling one these Infernal foes, don't worry -- as long as you don't leave your game session, you can release and restart the encounter at any time by clicking on the very same portal you created. Similarly, even after both bosses have been slain, your portal will remain active in the Heretic's Abode until your game session has ended, which means that if you're out of inventory space, you're welcome to leave and return without losing your loot.
(Please note that you cannot be sent to the same Realm of Pure Evil twice in a single game session. This means that if you create or have access to four or more Infernal Machine devices, in order to use all of them, you'll need to start up a brand new game once you've opened up three portals.)
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 demonic organs from each of their fallen foes, which can be used to create a Legendary item of unique power: the Hellfire Ring.
- The Writhing Spine, which drops from King Leoric or Maghda in the Realm of Discord
- The Devil's Fang, which drops from Ghom or Rakanoth in the Realm of Chaos
- The Vengeful Eye, which drops from Siegebreaker or Zoltun Kulle in the Realm of Turmoil
Similar to the wardens' keys, a full five stacks of Nephalem Valor will be required for the organ pieces to drop, and each level of Monster Power will increase their drop rate by 10%.
Once all of the organs have been collected, they can be combined at the Jeweler using a new design available for purchase from Squirt the Peddler. This design will teach your level 10 Jeweler four variations of the ring: the Hellfire Ring of Intelligence, the Hellfire Ring of Strength, the Hellfire Ring of Dexterity, and the Hellfire Ring of Vitality. Depending on which variation you choose, your ring will be guaranteed to roll one primary stat with a set value range of 170–200.
In addition to the guaranteed primary stat, each ring will always have the following:
- +35% Experience
- +4 Random Magical Properties
- No Level Requirement
- Bind on Account
- Chance to launch an explosive Hellfire ball when you attack
The Hellfire Ring will be considered Unique-Equipped, which means that players can only wear one at a time. Your followers will be able to equip the ring, however, and given the boost to experience and absence of a level requirement, the rings make excellent heirlooms to be passed down to each of your alts. If you no longer find the need for one of your rings, simply salvage it for materials at your local Blacksmith. So create one or create more -- the choice is up to you!
