There is a bug with the hellfire amulets that lets you keep your passive roll on the amulet if you only equip your amulet and let it break. Once you remove the broken amulet and put your gear back on, you still got the passive!
They need to fix this exploit right now...
PS. You can remove the passive by repairing your amulet.
Would be smart to NOT use this exploit if there is a rollback chance or whatever, just wanted to tell the world so maybe a bluepost would see this.
