Malthael has descended on BlizzCon® 2013 and the chill of death is already creeping its way through the convention halls, carrying whispers of Adventure Mode, Pandemonium, Crusaders, and more.
Whether you're following along at home, tuning in with the Virtual Ticket, or happen to be on-site bustling between panels and demos, you definitely won't want to miss any of the juicy recaps, interviews, or behind-the-scenes previews of Reaper of Souls™.
To help you stay up-to-date on all the latest expansion news, we'll be compiling media and fan site coverage from BlizzCon 2013 and posting it for you here! Be sure to check back regularly over the weekend for updates as they become available. If you find something we missed, add it in the comments below!
The world of Sanctuary is about to get a whole lot bigger. . .
In Diablo® III's upcoming expansion, Reaper of Souls™, players will have the opportunity to choose between two different modes whenever creating a new game: Campaign Mode and Adventure Mode.
These modes can be accessed at any time, and you're welcome to switch between them whenever you please. In addition, we've unlocked all difficulty levels, giving you even more control over your in-game experience. Don't want to play through the story four times on each of your characters? Done. Looking to farm in Adventure Mode at one difficulty, then switch over to Campaign Mode at a different difficulty? You've got it.
But that's just the tip of the iceberg. Adventure Mode also includes two brand new, incredibly entertaining gameplay features: Bounties and Nephalem Rifts.
Having the ability to go wherever you want whenever you want is certainly compelling. But, what if you're not in the mood to choose your own adventure and would instead prefer a little direction? Enter Bounties.
Bounties are optional, randomized objectives available only in Adventure Mode. In addition to providing players with a guided experience within a specific Act, Bounties are also intended to showcase all the different content Diablo III has to offer. Some example of Bounties you can pick up include slaying a unique monster (like Mira Eamon), killing a boss (like Queen Aranae), clearing a dungeon (like the Khazra Den), and completing an event (like Last Stand of the Ancients).
Each Act will have its own set of randomized Bounties for players to explore and conquer, and you'll receive new Bounties each time you start a new Adventure Mode game.
For completing a set of Bounties, players will receive gold and experience. We also want Bounties to provide access to powerful Legendary items unique to the system, but we're still experimenting with how that reward mechanic will work. Definitely stay tuned!

Bounty hunters are also rewarded with a new item, Rift Keystones. Rift Keystones grant access to another feature we're introducing in Adventure Mode: Nephalem Rifts.
Nephalem Rifts (previously called "Loot Runs") are randomized dungeons that are designed to be completed within 10-15 minutes. The goal of Nephalem Rifts is to provide players with a rewarding, endlessly replayable experience, one that continually offers new and exciting moment-to-moment gameplay. . .as well as heaps of loot. They're also what senior level designer Jesse McCree likes to describe as an opportunity to "break all the rules."
So, what does this mean in terms of actual gameplay?
First off, it means that Nephalem Rifts are completely randomized—random interior and exterior tile sets, random layouts, random lighting and weather, random monsters, and (of course) a random boss encounter to cap it all off. Each Nephalem Rift dungeon can be up to 10 levels deep, but even that's random too!
Here's just a peek at some of the crazy combinations you can experience as a result of this design:
In the spirit of breaking all the rules, Nephalem Rifts also include new shrines that will provide players with some pretty insane temporary buffs when activated, things like invulnerability, massive movement speed boosts, and a lightning aura that will one-shot any enemies who get within range. While these shrines would be overpowered in the campaign, they fit well within the self-contained environment of Nephalem Rifts.
We've had fun experimenting with monster density as well, which means there's always a chance your Nephalem Rift (or even one of the levels within a specific Rift you've opened) might suddenly get a little. . .crowded. For example, what would happen if we paired Skeleton Summoners from Act I and Morlu Incinerators from Act IV? Well, it'd look a little something like this:
(Pretty cool, right?)
To access Nephalem Rifts, simply bring a Rift Keystone to any town hub and click on the nearest Nephalem Obelisk. Step through the portal and get ready to kill ALL the things. As noted above, Rift Keystones can be earned by completing Bounties; however, they can also drop randomly anywhere in the world while in Adventure Mode.
Happy hunting!
As a special treat, we've put together a short video featuring Nephalem Rifts in all their random, chaotic glory. Please enjoy this first look at Diablo III: Reaper of Souls!
If you're at BlizzCon® this weekend, you can try out Adventure Mode first-hand at the Diablo III: Reaper of Souls PC demo area in Hall A of the Anaheim Convention Center. Just queue for the "Adventure Mode" line and get ready to explore!
For those of you at home or tuning in with a Virtual Ticket, be sure to stay tuned to diablo3.com for all the latest new and updates, including panel recaps, interviews, photos and links to coverage from media and fan sites in attendance.
Now that we've decided what kind of Legendary weapon we're creating (a one-handed sword), it's time to move onto the next stage of design: visual theming.
What do we mean by visual theming? In Diablo III, we love to give hero armor and weapons a specific signature, or theme. This theme is the aesthetic thread that connects and ties all the different parts (color, texture, shape, etc) of the items together. In a way, it gives the item its identity and helps inform not only its art, but its name, associated lore, and in many situations (in the case of Legendary items, at least) its stats and unique power as well.
For this particular stage of the Design a Legendary project, I sat down with art producer Nathan Lutsock and 3D character artist Aaron Gaines to discuss possible themes for our fledgling Legendary sword. Excited and intrigued by the idea, they quickly selected seven different options they felt would be fun to explore alongside the community, all of which I've detailed below (epic theme descriptions courtesy of Nathan):

"This blade would be styled to connect thematically to the desert city of Caldeum. An item with this theme could draw from the desert locale, a distinct architectural kit, the opulence of the Emperor’s palace, or even the Lord of Lies. Caldeum provides ample recognizable features for creative inspiration."

"This blade would be styled to connect thematically to the city of Westmarch. The capital of King Rakkis's empire demonstrates dark medieval visual cues that are very much in line with the motifs of the first Diablo game. A weapon in this theme will be benefit from the months of development that the Diablo art team invested when creating the characters and environs Westmarch. "
Serpent"This blade would have a visual connection to snakes and reptiles. Some of our most successful Legendary items sprang out of such humble beginnings. We start with a simple motif and asked ourselves, ‘What would I want out of a weapon in this style? What is the game fantasy of the player who wants this kind of item?' A classic fantasy theme like 'Serpent’ provides our artists with many avenues of interpretation."
Ancient Culture"This blade would be styled to represent an ancient culture no longer found on Sanctuary, or one that we've yet to fully flesh out in a game (Skovos, for example). Ancient culture motifs are exciting springboards for our artists, giving them the opportunity to expand the visual definition of the Diablo universe while keying off of visual hooks that they haven't yet dug into. Some of our most interesting item designs come out of explorations into the technology and designs of Sanctuary's lost peoples."
Mephisto"This blade would be styled to connect thematically to the wispy, skeletal Lord of Hatred. In addition to being a favorite character of the art team, Mephisto has a unique appearance among the Great Evils, and a blade associated with him would need to find a way to echo his character."
Duriel"This blade would be styled to connect thematically to the massive Lord of Pain. Bulky, brutal, and grotesque, interpreting this theme as a sword may prove something of a challenge. However, sometimes the most inventive legendary item designs come out of an unexpected pairing."
Diablo"This blade would be styled to connect thematically to the Lord of Terror himself. Capturing a design familiar to the character (a character that changes his appearance in every game, no less!) that still adds something fresh and makes a compelling player reward- this design might be the most challenging of the bunch."
Pretty cool, huh? But which theme should we use? That's up to you! Pick your favorite by using the voting options below, and be sure to spread the word. As with our previous vote, whichever theme gets the most votes globally wins!
After the poll has closed, we'll tabulate player votes from all our different Diablo III communities around the world to determine the winner and share the results next week. Don't delay, though—this poll will close Wednesday, November 13.
Over the past week, we've delved deeper into the renowned city of Westmarch, giving you a first look at its history, visual landscape, and bestiary. But there's still one more important design element to explore: its music!
To whet your auditory appetite, we've put together an exclusive preview track featuring just a small sample of new melodies you'll hear as you help defend this besieged metropolis against the Angel of Death. So grab your headphones, Sanctuary; stay awhile and listen.
To get a better understanding of what goes into creating a soundtrack for a game like Reaper of Souls™, we also sat down with Diablo® III Music Director Derek Duke for a quick Q&A.
Derek: The music of Westmarch was some of the first created for Reaper of Souls. In fact, it was written while I'd just started working on the opening cinematic. The soundtrack for Westmarch picks up right after the opening cinematic ends, so it has to instantly get you into that dark, dangerous, gothic sort of pace.
I really wanted to match that pace and encapsulate the creepy, ominous vibe the developers were going for with Westmarch in that early music. That all begun with the instrumentation. The orchestral voicing used in Reaper of Souls, and particularly in Westmarch, is weighted a bit more traditionally. This means more woodwinds and less brass than what’s commonly used in today's scores. To my ear, it makes a big difference, and puts the orchestral emphasis a bit more on voicing (harmonized melodies that contain one or more instruments) and colors (the quality of the sound, or timbre).
Derek: In Westmarch, I'd say sonic themes in the music work to propel the story by creating associations.
For example, there are a couple of the themes and musical textures established and attached to Malthael from the very beginning, starting in the intro cinematic with his arrival.
There's a deep, otherworldly moaning underneath the strings. We use a percussion technique to get that sound out of the timpani and bass drum by rubbing it with a super-ball or wet finger. (My producer had a real "WTF" moment when he heard that sound coming from the orchestra, by the way.) Following that with the orchestral bells seemed the obvious choice for the Angel of Death—a character not for whom the bell tolls, but the one who's holding the bell and tolling it for everyone else.
These musical textures and combinations are often the sign of Malthael's presence or the harbinger of his arrival. As you play through Westmarch, you hear these musical ideas used throughout the music, changing and evolving contextually as the story moves forward. Keep an ear out for them!
Derek: Yes, definitely. I don't want to give away too much of the story, but it's the time and places and evolution of the music pieces that help to move the story forward.
Derek: Like much of the in-game music in Diablo III and Reaper of Souls, this an arrangement of several music pieces, some assorted flavors.
It starts with some of the broad Westmarch crescendos or swells, and you’ll hear the giant tam-tam (or gong), and bowed acoustic guitar playing above.
It then moves in to the Y'Anu theme over the moaning tympani and bass drum. This theme is first heard in the Reaper of Souls intro cinematic, which takes place in the Tomb of Rakkis where Tyrael attempts to hide the Black Soulstone. Y'Anu was written as a meditative chant of the Horadrim whereby the acolyte could meditate on the mysteries of Anu, or The One.
And last but not least, Malthael's signature theme (which I mentioned above) buttons up the end.
Thanks for listening, and I hope you all enjoy!
Following the defeat of the Prime Evil, the mortal realm of Sanctuary should have an entered an age of hope and prosperity. Instead, this event has drawn out a being of immense power, one more sinister than any demon: Malthael.
Having plucked the Black Soulstone from its tenuous hiding place, the Angel of Death now moves on Westmarch, the great martial and mercantile capital of the west. It is there that your heroes will encounter the first of his forces, a macabre combination of ghastly lieutenants and baleful constructs.
Little is known of these creatures, as most who have encountered them have perished. Fortunately, a Horadrim under the command of Tyrael by the name of Lorath Nahr has experienced the foul reapers of Westmarch first-hand and survived to tell the tale, documenting both their behavior and perceived origin.
It is some of his accounts which we'll examine today, offering just a glimpse at what horrors await you within the cobbled streets and abandoned homes of this once beautiful, thriving city.
