Behold! Two epic new bonus items have just been spotted in the mortal realms, both of which will be granted in the future to anyone who pre-purchases the Reaper of Souls™ expansion digitally on Battle.net, or anyone who redeems a Reaper of Souls retail game key on or before March 31, 2014.
Check them out below:
Wings of Valor: Summon the radiant wings of the Archangel of Valor for your characters in Diablo III.
Valla the Demon Hunter: Unlock Valla the Demon Hunter in Heroes of the Storm—our upcoming free-to-play online team brawler featuring iconic Blizzard characters, fast-paced combat, and epic battlegrounds.
If you've already digitally pre-purchased the Reaper of Souls expansion, either as the standard edition or the Digital Deluxe Edition, then you're all set! These bonus items will be granted to your Battle.net account as follows:
If you pre-order Reaper of Souls at a retail store—either a physical standard edition or physical Collector's Edition—be sure to redeem your Reaper of Souls game key via your Battle.net account on or before 11:59 PM PST on March 31, 2014. If you redeem your game key after that date, your pre-order loot will be consumed by the fires of the Burning Hells and lost forever. While you have six days from the time the expansion launches on March 25 to the time you must enter your code, to be safe, you should secure your preorder today and be ready to input your game key on launch day.
For more information on the upcoming March 25 launch of Reaper of Souls, be sure to check out the official expansion website, and keep your demon-weary eyes glued to www.diablo3.com for the latest news on the game.
Until then, slay well, Nephalem.
- The Diablo III Team
In preparation for the launch of patch 2.0.1, the Reaper of Souls™ Beta and Patch 2.0.1 PTR servers will be brought offline this evening at 5:00 p.m. PT. At that time, players will no longer be able to log in to the Beta or PTR client, all Beta and PTR accounts (including character information) will be reset, and both our Beta forums and PTR forums will be marked as read-only.
We'd like to thank everyone who has participated in the Reaper of Souls Beta and Patch 2.0.1 PTR. You've done an amazing job of testing, and we greatly appreciate all of the feedback you provided during this critical phase of development.
We look forward to releasing patch 2.0.1 to public shortly and encourage everyone to stay tuned to this website for exciting news and updates regarding the upcoming launch of Reaper of Souls!
Patch 2.0.1 will introduce our updated Paragon leveling system (often referred to as "Paragon 2.0"), adding even more end-game character advancement and replayability. This update will affect all Diablo III accounts across all regions as the patch is implemented, and is currently available for testing on the Patch 2.0.1 PTR and Reaper of Souls Closed Beta.
For those of you who haven't yet experimented with this new system, here's a first look.
The initial implementation of the Paragon system introduced in patch 1.0.4 was designed to provide players with additional end-game progression, offering bonuses for experience gained past the standard level cap. This system was created to accompany and complement the more innate item-based progression in Diablo III, which is all about finding powerful artifacts and putting them to use against the demonic legions of the Burning Hells.
While the original version of the Paragon leveling system achieved its many goals, with time players would max out at level 100 and no longer feel rewarded for vanquishing evil. With patch 2.0.1, we're making three big changes to the Paragon system that are aimed at giving you greater control over your hero, promoting variety in build options, and offering more character customization than ever before.

The first change we’re making with Paragon 2.0 is removing the level cap, so you will always be able to earn Paragon experience once you've reached max level. Play as much as you like—you'll always be able to earn more Paragon levels!

The second change is that Paragon levels are now account-wide per game mode (i.e. Normal and Hardcore). All Normal heroes on an account will share a Paragon level. Similarly, all Hardcore heroes on an account will share a Paragon level. After patch 2.0.1 goes live, any Paragon experience you gain on your Normal or Hardcore heroees will contribute to your account's Normal Shared Paragon level or Hardcore Shared Paragon level, respectively.
We made this change so players wouldn't feel obligated to continue playing the same hero over and over again in order to maximize their farming efficiency. We want players to have fun with the game, to experiment with different classes, and to feel rewarded for their time investment, regardless of what hero they’re playing. We also want everyone to fully enjoy the new content coming in Reaper of Souls—including the Crusader class—without feeling as though they’ve "wasted Paragon levels" on a previous hero.
While only max-level heroes can earn shared Paragon experience and contribute to your account's shared Paragon level, all heroes (regardless of level) will be eligible to receive Paragon Points—our third major change to the Paragon leveling system.

As noted, the third change is that the rewards for gaining Paragon levels have drastically changed. In Patch 2.0.1, the static Magic Find, Gold Find, and class stat bonuses awarded for each Paragon level are being replaced by spendable Paragon Points.
In the new system, whenever you gain a Paragon level, you will receive a Paragon Point to allocate at your discretion. Paragon Points are earned in four separate categories: Core, Offense, Defense, and Utility, and the Paragon level you earn will determine the category in which that Paragon Point can be spent. Paragon level 1 will give you a point to spend in a Core stat, Paragon level 2 will give you a point in Offense, Paragon level 3 will give you a point to spend in Defense, and Paragon level 4 will give you a point to spend in Utility. Paragon Point progression for all future levels will follow this same pattern (sometimes referred to as round-robin).
In addition, each category also four different attributes. Spending points in these attributes will provide specific bonuses for your hero.
Core points can be spent on your class's primary stat, Vitality, Movement Speed, or bonus Class Resource.
Offensive points focus on increasing your damage output and efficiency, and include Attack Speed, Cooldown Reduction, Critical Hit Chance, and Critical Hit Damage.
Defensive points include stats that help improve your survivability. Options include bonus Life percentage, bonus Armor, Resist All, and Life Regeneration.
Utility points include more specialized stats that allow players to refine their builds. These points can be spent on boons like Area Damage, Resource Cost Reduction, Life on Hit, and Gold Find.
At present, all attributes in each category other than core stats (Strength, Intelligence, Dexterity, and Vitality) have a cap on the number of points that can be allocated to them, which also means there is a cap to the total number of Paragon Points you can accumulate in three of the four categories. By the time you reach Paragon 800, you will have maxed the number of points that can be allocated to the Offensive, Defensive, and Utility categories and all future Paragon levels you earn going forward will grant you a Paragon Point in the Core stat category instead.

To provide an example, here's a new level 1 hero. This hero will begin with a Shared Paragon level of 127 as well as 127 Paragon Points, which can be allocated at will to the four different categories.
Heroes who have gained Paragon experience under the old system will transition seamlessly to the new system. When Paragon 2.0 goes live with patch 2.0.1, we'll being adding up all the Paragon experience on each of your heroes and then using that combined total (the total amount of Paragon experience you have, not the total number of Paragon levels) to determine your Shared Paragon level. Again, this will be broken down by game type—Normal and Hardcore.
Players can distribute their earned points through the Paragon interface, accessed by clicking the "Paragon" button located in your hero's character sheet.

You can experience the new Paragon system coming in patch 2.0.1 on the PTR. Check out how your heroes feel with new stats, play around with different stat builds by spending Paragon Points, and check out the new Paragon progression curve. Once you’ve tried it out, visit the PTR forums to leave your feedback—we'd love to hear what you think!
