Now in America, patch 1.0.7 is available for Diablo 3 and it brings some massive changes to the game.
For instance, brawling is a brand new feature in this patch..
For those who wish to test their mettle against fellow Nephalem, your time has come. Players will now be able to battle one another in a new zone designed specifically for this style of combat called “The Scorched Chapel.” This zone can be accessed by speaking with Nek the Brawler in any of the four Act hubs, and supports 2 to 4 players in a Free-For-All format.
In addition, the resurrection timer will no longer increase if a player is killed multiple times. The experience bonus for killing enemies on Monster Power Levels 1-10 in Inferno has increased. Also, when resuming a game, players will be placed in a town rather than the last known checkpoint.
There are also some class changes, including some major ones for the Monk and Wizard.
A new crafting reagent has also been added to the game, Demonic Essence.
