The Hellfire Amulet essentially gives the character five passive skills: it will have a secondary legendary affix that provides a randomized passive skill of the class who crafted it. The passive skill cannot be re-rolled once an amulet is crafted, so it may be very challenging to get an optimal combination of the skill and stats. Each passive skill only works for the class that normally has it: one cannot use this amulet to gain a passive skill of another class. Passives also do not duplicate if taken normally and on the amulet.
Stats (Level 70)
To make a Hellfire Amulet, one will need all the same materials as those for the level 70 Hellfire Ring (50,000 gold, Heart of Evil, Vial of Putridness, Leoric's Regret, Idol of Terror), plus 10 Forgotten Souls.
Regardless of whether the player chooses their current class's core stat, the passive rolled is guaranteed to be for their class.
- In patch 2.3, a bug/exploit existed that allowed Hellfire Amulet to grant all passive skills at once.
