Patch FeaturesNew Feature: Dueling
For those who wish to test their mettle against fellow Nephalem, your time has come. Players will now be able to duel one another in a new zone designed specifically for this style of combat. This zone can be accessed by speaking with Nek the Brawler located at the inn in New Tristram, and supports 2 to 4 players in a Free-For-All format.

Bug FixesD3RMT will be experiencing several hours of maintenance later today as we migrate to a new web host. During this time, the website unavailable. When the migration is complete, it may take some time for DNS changes to take effect. This can take anywhere from a few minutes to a few hours and is out of our control.
Following the migration, we will be introducing some forum changes to help combat spam. Members with less than 10 posts will be prompted with a CAPTCHA when replying to a thread. Additionally, members with less than 5 threads or 25 posts will be prompted with a CAPTCHA when creating a new thread. Hopefully this is not too much of an inconvenience.
Unidentified Items Will Not Copy Over to the PTR for 1.0.7
Players have been worried that the PTR will ruin the value of their unidentified items. Lylirra has just put those concerns to rest, confirming that unidentified items will not copy over to the PTR.
For the patch 1.0.7 PTR, unidentified items cannot be copied over from the live client to the PTR client.
Since there won't be any warning or error messages for this restriction (the stash/inventory slots which held the unindentified items will just appear empty once your character is copied over), we'll be creating a reminder post in the PTR Feedback forum once the PTR is live.
New crafting Amulet requires Fiery Brimstone
The new crafting amulet plan will require Fiery Brimstone. They are also considering requiring Fiery Brimstones for the other plans.
Don't believe that's planned, but one of the new crafted items (the amulet) will require Brimstones as a reagent.
We know that this likely won't resolve the Brimstone surplus completely, and we may end up adding Brimstones as a reagent for some of the other recipes and/or changing the current cost for the amulet. It's something we've discussed, and we're open to your thoughts on the matter.
Even so, the new Rare items already have a fairly high reagent cost, and we don't want to make crafting them too prohibitive, as that will mean we won't see much movement of commodities out of the economy. When it comes to item sinks, it's usually better to have a larger number of players crafting items with a slightly less expensive reagent cost than it is to have a very small number of players crafting items with a much more exorbitant cost.
Speaking of, I feel it's important to note that the crafting costs of items being introduced in 1.0.7 are subject to change, so please keep that in mind before liquidating certain assets (or, conversely, stocking up on others).
New crafted items do not salvage into Demonic Essence
Currently the new crafted items do not salvage into Demonic Essence, although they may consider having very small chance to salvage into a Demonic Essence before the patch releases.
The new Rare crafted items currently aren't designed to salvage back into a Demonic Essence. Right now they're set to salvage into Rare crafting materials, just like other Rare items.
We're thinking about allowing the items to have a very small chance to salvage into a Demonic Essence, but that's definitely not a confirmed decision. It won't be something that's available on the first build of the PTR.
Nephalem Valor is not Required for Demonic Essence to Drop
Under the current design which is shipping with the PTR, Nephalem Valor will not be required in order for Demonic Essences to drop.
