The Monk

The panel began by showcasing the monk as a fast but fragile melee fighter, providing a contrast to the barbarian's slower but harder-hitting melee presence in the game. The monk's influences draw from classic pen and paper RPG archetypes, but his style also incorporates the development team's love of arcade-style fighting games. The monk combo system uses many of these fighting game influences, allowing special combo skills to be mixed and matched together to gain the best results from each skill.

While many of the monk's influences are from traditional light and fast melee, he is indeed a holy warrior. His use of holy magic flows through each of his skills, combining martial arts with divine justice. It's a class that prefers speed over toughness, but that doesn't mean he's incapable of handling the hordes of enemies that he'll be fighting. The skills and use of the combo system makes the monk a character that will be a bit more challenging to play than the other heroes in the game, but when played expertly can unleash truly devastating damage upon the demonic hordes facing him.

Monk Weapons

The history of the monk's weapon choices was then covered in the panel. The initial concepts and ideas for the monk proposed him as an unarmed class. Instead of wielding weapons, the monk would have instead relied purely on using the strength of his fists, body, and feet in combat. While many of his skills still retain a purity of physical combat, weapons now add visual depth to the class in addition to the ever-important item collection and upgrades in the Diablo series. The solution to keep the initial intent of the monk as unarmed holy fighter, while stile introducing weapons, was to create weapon types specific to the class. These come in the form of the combat bo and fist weapons.

Combo Moves

The combo system that encompasses many of the monk skills is what truly sets this class apart. Monk skills that use the combo system can be chained together in different orders to achieve different results. This was demonstrated at the event by covering the monk skills Way of the Hundred Fists, Crippling Wave, and Exploding Palm. Each skill has three steps which are used in order each time the skill is used. For instance, the first hit of Exploding Palm will deal some damage, the second hit will deal a little more, and the third hit will apply a bleed ‘damage over time' (DoT) on the enemy. This particular DoT has the unfortunate effect (for the enemy) of causing more damage if they move, and causing them to explode and cause damage to all enemies around them if they die while it is still applied.

If you were to use the first two steps of a different combo ability you could then use Exploding Palm and immediately be using the third step, which is the devastating DoT. Each combo skill can be used in this way, mixing and matching which step of the combo from each skill you want to use. Knowing each step of the skills, moving between them and using them appropriately in each situation will be a testament to the skill of the player. These quick hits with sequential variety also add a very iconic martial arts flavor to the class in addition to their tactical skill requirement.

Skill System

The panel then moved on to the skill system used by all classes, also commonly referred to as the skill trees. The Diablo III skill trees have gone through multiple iterations, and the showing at BlizzCon introduced the newest version. First the panelists began by going over the previous iteration of the skill tree and the issues with it that led to the recent changes. First, the previous tree design required too many skills, as each tab was advanced down individually. Skill types and effects were essentially required to be repeated to allow you to build down a tree and still get the variety of options every player should have available. It also put too many constraints on customization, as you started to build down a tree you were encouraged to continue down that same tree. Diversification in other trees was essentially discouraged with this approach. And since Diablo classes only have one role -- killing demons -- specialization in specific trees isn't a hugely important separation of class function. The new skill system layout has each “tree” laid out side by side, correcting another issue: that having tabs for each tree didn't allow you to see an overall view of your class build at a glance. Last but not least, the old tabbed skill system was just too much of a departure from the classic Diablo II skill tree system.

With the new side-by-side view of the skill trees and altered design of progression down the tiers, you're no longer constrained to spend five skill points to continue down to the next tier of each individual tree. Instead, any five points in any skills of a tier will unlock the next tier of all three trees. This allows a player to buy skills from anywhere they choose, mixing and matching skills from each of the three different disciplines.

With the new system, there's a far greater ability for customization, players don't feel like they need to waste points to get to a skill they want, there doesn't need to be a lot of redundant skills, and specialization will come through “deep spending,” or spending a lot of points in a single skill -- similar to Diablo II.

However, the new system is still a work in progress, and the team was candid about the issues it may still produce. Their concerns include that it may be too overwhelming to allow the entirety of all three trees to be moved across freely, that the skill screen being so big to show all three trees takes up a large amount of the screen while the skill window is open, and that there's the ever-present potential for encouraging “cookie cutter” builds, which become the undisputed “best” builds and are universally used.

Runes

The feature many players were excited about from its showing at last year's BlizzCon was curiously disabled in the playable build at BlizzCon, but the team was quick to explain why the rune system isn't making an appearance. He began by explaining that skill runes still represent a core piece of the customization options in Diablo III, and that they aren't being removed, just temporarily disabled.

He then went into the process of how runes make it into the game, and how the design flow works against the ability to implement a lot of runes at this point in development. If any number of variables contributing to a rune change, not the least of which is the design of the skill the rune alters, the rune and its function essentially has to be completely restarted from scratch. As players are able to see in this year's playable demo of Diablo III, many of the skills have changed, many added, and some even removed or replaced. Creating runes while the skills are still in this state of constant and heavy revision would mean a lot of wasted effort on the part of the development team.

Monsters

The panel then shifted gears and held up to its namesake by moving to the design and implementation of the enemies that inhabit Sanctuary. The section kicked off with the overall design philosophy for creating monsters in Diablo III. The points made were that monsters work best in Diablo when kept simple, that their complexity shows best when it comes from combining different monster types in groups, that being able to identify monsters easily is key, and that the game should keep introducing new monsters to the player.

The panel then went into the monster creation process, starting with the first step -- pitching the idea. This could come from any area of the team, but generally starts from one of three places: a visual concept from the artists, an environmental concept from the world designers, or a behavioral concept from the game designers. The second step is putting it down on paper and fleshing the monster out. What is it going to do, what are all of its attacks, what is its visual style and theme, is it large or small, and at least one piece of concept art. The third step takes it from paper to actually crafting the creature. The modelers create and texture the monster, the technical art team does a first pass on its visual and attack effects, and the animators take their first shot at bringing the monster to life. It then moves into an implementation phase of bringing it into the game world with things like health and damage stats, immunities and resistances, movement speed, and its basic attacks and powers. Then it's actually seen in-game for the first time. After reviewing how it acts and reacts, and how the design and art goals have been reached, it goes through further refinements of each step.

After creating texture variants, rare/champion variants, fine tuning its abilities and interactions, and finalizing the art, the monster is now a full addition to the world of Sanctuary.

More Monsters!

The next stage of the panel showcased specific foes. The process began with two new enemies seen for the first time in the BlizzCon demo, the snakeman and sandwasp, then moved on to everyone's Diablo family favorite, the fallen. Three varieties of fallen were shown -- the rank-and-file fodder imp, the resurrection-happy shaman, and the crazy-cousin lunatic.

While the panelists talked about how these monsters interact with the world around them, and even their relationships with one another as they work against our heroes, they moved on to an interesting topic of how design can sometimes end up very differently than originally planned. The dune thresher, originally announced in September of 2008 on the official Diablo website, served as their example. The original design of the monster had a key goal in mind: getting across the idea that “the sand isn't safe.” It was originally inspired by the movie Tremors, and that connection definitely brings across the idea that the soft sandy areas are vulnerable to attack from below. Other goals of the thresher were to have it able to submerge freely and require the player to make it vulnerable to attack by luring it onto some of the rocky outcroppings in the area. This would encourage tactical fighting by using the environment as a way to make the enemy vulnerable.

Instead the results were that the player was confused, they didn't notice when the thresher was attacking while submerged, and ultimately they would simply ignore the dune threshers to instead blow up the many easily noticeable fallen and cultists in the area.

So to fix these issues they went over some of the solutions they've used so far. They made the thresher harder to escape, increased its speed while submerged in the sand, discarded the sand/rock mechanic and instead had the creature submerge when distant from the player, and finally removed the ability to attack while submerged. While they explained that these changes have helped remove a lot of the confusion, they still haven't quite reached their original intent, which is to make the player feel frightened to be walking on the open sand, so there's still more work to do. The development of a monster doesn't always work out the first time, but the team will keep at it until it's right.

In Closing

The panel then closed, before going to crowd Q&A, by showing some of the mistakes and accidents that sometimes happen during game development. They showed a series of videos of effects, programming, and art errors. The crowd favorite was certainly the “burrower” (briefly seen in the Worldwide Invitational announcement videos) that had its texture accidentally replaced with Deckard Cain's -- creating a thin, rodent-like version of the Horadric mage, digging and burrowing in the ground.

Who called it?!

And people doubted me and said the idea was stupid.
