All four Infernal Machine types will be needed to make the Hellfire Amulet.

Act IV – Nekarat, the Keywarden of Fright, can be found in the second tier of the Gardens of Hope.

Act III – Xah’Rith, the Keywarden of Terror, can be found in Stonefort.

Drops the Infernal Machine of Putridness.

Act II – Sokahr, the Keywarden of Putridness, can be found in Dahlgur Oasis.

Act I – Odeg, the Keywarden of Regret, can be found in the Fields of Misery.

There is a single Keywarden per Act in Acts I-IV, and they will always drop the same Infernal Machine type:.

They will only appear and drop these on Torment I or higher, with more Machines dropping from the Keywarden on average the higher the difficulty is (up to 4).

These Machines are needed to get the actual materials to craft the Hellfire Amulet.

You will need to find and kill four Keywardens in order to get Infernal Machines.

There are a few steps you will need to take to get these:

You will notice that you need 4 materials to make a Hellfire Amulet (aside from the 10 Forgotten Souls): Leoric’s Regret, Vial of Putridness, Idol of Terror, and Heart of Fright. Note that the recipe costs 5,000,000 Gold. Simply talk to Squirt the Peddler in the Hidden Camp in Act II and purchase it, then teach it to your Jeweler. Obtaining the recipe is the easiest part. The Amulet will have your class’s Passive regardless of the variant you craft. However, if you do wish to make one, the process will be the exact same as with the Hellfire Amulet.Įither the Amulet or the Ring can be crafted as a Dexterity, Intelligence, or Strength variants, but the materials needed will be the same.

The older Hellfire Ring is now an obsolete Ring that isn’t used in any of the most popular builds. This piece of equipment cannot be obtained through normal means, however – you will need to find its crafting recipe and then acquire the materials to make it. The Hellfire Amulet can definitely be useful in some of the builds, as it will give you an additional Passive effect from your class, generated at random (allowing you to have 5 total).
