The Infernal Machine

[420]

A new event was added with the release of the 1.0.5 patch.

New Event: The Infernal Machine

The Components
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 Infernal Machine Blacksmithing Plans will drop from Nekarat the Keywarden in Act IV - Silver Spire Level 1

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.

The Device
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 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.

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.)

The Bosses
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.)

The Rewards
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.

Three organ pieces will be needed to forge 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!

Now that I've had a chance to play around with it, here is some more info and tips regarding the Infernal Machine event.

Drop Rates
The drop rates are the same for the Infernal Machine plans, keys, and demonic organs.

Remember, you must be in Inferno difficulty and you must have a stack of 5 Nephalem Valor (NV) in order for any of these items to drop!

The drop rate itself is dependent on the level of Monster Power (MP):

Monster Power - Chance to Drop
MP0 - 5%
MP1 - 10%
MP2 - 20%
MP3 - 30%
.
.
.
MP10 - 100%

Note: Magic Find has no effect on the chance for these items to drop. (Official Source)


Farming Plans
The plans for the Infernal Machine are dropped by Nekarat the Keywarden in Act 4 - Silver Spire Level 1. Start a game on the final quest (Prime Evil) and use the way points to travel to the Gardens of Hope 1st Tier and Gardens of Hope 2nd Tier and clear those areas. Once you have 5 Nephalem Valor, go to the Crystal Colonnade waypoint and travel through the Gateway to the Silver Spire to Silver Spire Level 1 and search for the Keywarden.

Note: Once you find the plans you won't have to farm this Keywarden again.


Farming Keys
It's a good idea to start a game at the final quest of the act so that you have access to all the waypoints. Most of the time you will run into at least one elite pack in the area where you are searching for the Keywarden before you encounter the Keywarden so you can usually get by with getting just 4 Nephalem Valor before going after the Keywarden. If you run into the Keywarden before getting your 5th NV just leave it alone and go to a different waypoint and search for an elite pack.

Key of Destruction
Dropped by: Odeg the Keywarden in Act I - Fields of Misery

Building NV: Go to the Festering Woods waypoint, it is a small area containing either two elite packs or one elite pack and one random event worth a point of NV. The area also contains two small sub-areas, Crypt of the Ancients and Warrior's Rest, which each contain an elite pack.

Key of Hate
Dropped by: Sokahr the Keywarden in Act II - Dahlgur Oasis

Building NV: Go to the Archives of Zoltun Kulle waypoint and clear out the sub-dungeons The Unknown Depths and The Storm Halls.

Note: Sokahr is the hardest Keywarden to find due to the size of Dahlgur Oasis so this run tends to take the longest but you will usually run into a couple elite packs before you find the Keywarden so you can try starting the hunt with 3 NV.

Key of Terror
Dropped by: Xah'Rith the Keywarden in Act III - Stonefort

Building NV: Start at The Keep Depths Level 1 waypoint and work your way backwards. You will often find a NPC named Ironsmith Maldonado who will start the random event Forged in Battle which is worth a point of NV. From there you can clear that area then go to the The Keep Depths Level 3 waypoint and clear that area if you need more NV.


Farming Organs
When you have used the plans to create an Infernal Machine portal device you can open a portal by using the device in the Heretic's Abode, located in the boarded up house behind Brother Malachi the Healer. Note: The Infernal Machine portal device is destroyed after use.

Three organ pieces will be needed to forge 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

Important! The Infernal Machine portal device will open a single portal to one of three random areas where you battle a pair of bosses. Each battle has a chance to drop one organ (drop rate is the same as plans/keys detailed above). Since the portal that opens is random it is optimal to use three portal devices in a single game so that you get a portal to all three areas.

EDIT 11/11/12: Only one active portal can be open at a time. Once the bosses in the active portal are killed the next portal can be opened in the same game.

So now a heads up regarding these. This coming weekend will be my last one on D3 until after the summer and I have 8 of them now possibly 9 soon so lets kill some ubers soon.

[Soul Sojourner]

Never even noticed this topic before. These are kind of similar to Maps in PoE. We open em' up in the eternal laboratory and go to a different plane/realm clean the area kill the boss and move on. They seem a little different, but with a similar concept.

If they're anything like maps they must be pretty fun.

They aren't big maps, more like small arenas. There are three of them and each one has just two ueber bosses in them and nothing else.
