Once all of the components have been collected, players can finally forge the Infernal Machine at the town blacksmith. For example, setting the Monster Power at 10 will yield 100% drop of a component. Additionally, players can utilize “Monster Power” to increase the likelihood of a successful drop. Keywardens can be faced on any difficulty however, only Inferno difficulty along with five stacks of Nephalem Valor will potentially yield a chance to drop components for the device.
Since Patch 1.0.5 has been released, all the attention has been drawn to the new device called the Infernal Machine.
