Patch 1.0.5 Sneak Peek

Blizzard Tracker: September 13, 2012

We’ll have articles in the coming days providing all the details on the upcoming patch, but we wanted to give you a sneak peek at what major features to expect.
Defensive Skill Changes
In our eternal quest to promote build diversity; we’ll be making changes to defensive skills across the board while simultaneously reducing incoming damage. The net result is a survivability buff for players, and an increase in build options as defensive abilities become less “mandatory.”

New Event: Infernal Machine
The Infernal Machine is a device that will allow level-60 players to battle “uber” versions of some of Sanctuary’s most nefarious bosses. While the rewards for defeating these bosses will be great, some assembly is required.

New System: Monster Power
Similar to the “Players 8” command in Diablo II, the Monster Power system is designed to give players more control over how challenging enemies are in each difficulty.

This and more is coming in Patch 1.0.5! Stay tuned for all the gory details.
