It's patch day today for Diablo 3. 1.0.5 adds the Infernal Machine event, doubles the drop rate of Legendary items, and gives players the chance to modify monster power for better experience and loot chance at all difficulty levels.
There were plenty of other tweaks and bug fixes, so make sure you give the final patch notes a scan so you don't end up dying when you weren't prepared for the changes.
