Combat is simplified in Diablo III, with skills factoring in weapon damage, attack rate, [[main stat]], [[critical hit]] damage and [[critical hit chance]] as the chief factors. All elemental types of damage are calculated the same as physical damage, and there is no real [[to hit]] factor, nor is there much variety between weapon types, with no special bonuses, such as blunt weapons dealing higher damage to the undead (as was the case in Diablo 1 and Diablo 2.)

While damage types were a major feature during Diablo III's development, this aspect of combat was simplified before release and all variety between different damage types was removed from the game.. The graphics remain different, but players often refer to the different elemental types as "red damage," "green damage" and so forth, since the color variations are purely cosmetic. Jay Wilson explained this in regards to poison damage shortly after release:[http://diablo.incgamers.com/blog/comments/jay-wilson-explains-poison-damage-in-diablo-iii]

Poison in D3 does not act like D2. It’s not a guaranteed dot. If a skill has a DoT reapplying refreshes duration unless noted. Some skills have DOT mechanics, and some of those skills use poison damage, but poison damage does not DOT by default. I’ll repeat: poison damage does not work like D2. It does not apply a persistent effect, it’s a type of damage like fire or holy. –JayWilson</blue>
 +
 +
All elemental damages are calculated just as if they were physical damage, with a character's [[main stat]], weapon damage, and skill damage adding up no matter what types of damage they are. For instance, a Wizard might use a wand with Arcane damage to cast Meteor (fire damage), and while the resulting attack would look like the Meteor skill, it wouldn't be fire or arcane damage in any effective way. It's just damage, exactly as if the wand had physical or fire or lightning damage.

==Critical Hit Effects==
 +
 +
[[Image:Barb-cold-light.jpg|thumb|300px|Axes with cold and lightning damage show their graphics.]]
 +
During development, each type of damage was going to create a special bonus effect when a [[critical hit]] was scored. This feature was removed from the game shortly before release when all damage types were simplified. The only remaining effect is visual; monsters that die to poison damage leave gas-smoking green corpses, monsters that die to lightning appear charred black and crispy, fire damage will set corpses on fire, etc. These effects are amplified when monsters die to a critical hit of that damage type, and they explode in flames, or lightning-crackling chunks, etc.
 +
 +
All very pretty, but without any strategic function in Diablo III.
  
 
As in previous games in the series, there are numerous types of damage in [[Diablo III]]. Various spells, [[skill]]s, [[runes]], and [[weapons]] channel their destructive might into one (or more) types of damage. Characters and [[monster]]s counter these attacks with equivalent types of resistance and immunities, and players must find the right balance of each if they wish to succeed in their battles.

The following lists the damage types and their critical hit effects, but these are purely visual without any special function.
Damage in Diablo III takes the following forms. Every form of damage can count for a [[critical hit]] (caused by various item or skill properties) and when a "crit" is landed, a bonus effect is added along with increased damage. Targets that die to critical hits usually explode in gory and thematically-appropriate fashion.
+
 
 +
[[Physical Damage]]: No special graphic.
 +
* Critical hit deaths may explode in novas of blood and gore.
  
[[Physical Damage]]:
+
[[Arcane Damage]]: Purple in coloration. Dead monsters with glow with a purple light.
* Critical hit: Deals double damage.
+
* Critical hits were going to "[[silence]]" targets, which would have prevented summoners from resurrect or casting buffs on monsters. This feature was removed during development.
  
[[Arcane Damage]]: Purple in coloration.
+
[[Cold Damage]]: Blue in coloration. Targets may be chilled and slowed, and will turn blue and may shatter upon death.
* Critical hit: Arcane crits "silence" targets. (Silenced targets can not cast some spells, such as a [[Skeletal Summoner]] or [[Goatman Shaman]] resurrecting fallen minions.)
+
* Critical hits were set to freeze targets before this feature was removed.
  
[[Cold Damage]]: Blue in coloration.
+
[[Fire Damage]]: Red in coloration, often with flames. Dead enemies may appear blackened or charred.
* Critical hit: Cold crits freeze targets for 2 seconds. (Duration affected by numerous other factors.)
+
* Critical hits with fire were set to deal a [[DoT]] effect adding fire damage, but this feature was removed.
  
[[Fire Damage]]: Red in coloration.
+
[[Lightning Damage]]: White-blue in coloration. Dead enemies will appear crisped and dried up.
* Critical hit: Fire crits set targets ablaze, adding [[DoT]] to the initial fire damage.
+
* Critical hits were set to stun targets before this feature was removed. During pre-release testing skills such as [[Electrocute]] were highly effective due to their ability to repeatedly stun enemies.
  
[[Lightning Damage]]: White in coloration.
+
[[Holy Damage]]: White in coloration, this damage type is not found on weapons, but is dealt by some Monk skills.
* Critical hit: Lightning crits stun targets for 2 seconds. (Duration affected by numerous other factors.)
+
* Critical hits were set to provide an AoE heal to friendly nearby targets, before that feature was removed from the game.
 +
** Resisted by: Arcane resistance is tabbed for resisting Holy damage. This is only a factor in PvP, since no monsters deal holy damage.
  
[[Disease Damage]]: Green in coloration. (Formerly known as "Toxic.")
+
[[Disease Damage]]: Green in coloration. Formerly known as "Toxic" this damage will turn enemies green and cause puffs of green gas to rise from their corpses.
* Critical hit: Disease crits deal an unknown bonus.
 
 
* Resisted by Poison resistance.
 
* Resisted by Poison resistance.
** Diseased units suffer a damage debuff; they take more damage and deal less.
+
** Diseased units were set to suffer a damage debuff; they take more damage and deal less, but this was removed during game development.
 +
 
 +
[[Poison Damage]]: Green in coloration. (Acid damage is poison.) (Poison and Disease are similar, but not the same.[http://diablo.incgamers.com/blog/comments/diablo-on-damage-types-and-resistances/])
 +
* Poison does not "poison" targets with a [[DoT]] effect. It's just another type of direct damage in Diablo 3.
  
[[Poison Damage]]: Green in coloration. (Also known as Acid.) (Poison and Disease are similar, but not the same.[http://diablo.incgamers.com/blog/comments/diablo-on-damage-types-and-resistances/])
 
* Critical hit: Poison crits deal an unknown bonus.
 
* Resisted by Poison resistance.
 
** Poisoned units suffer a health debuff; their regeneration and healing is lessened or reversed.
 
  
[[Holy Damage]]: White in coloration. (Found mostly on [[Monk skills]].) Extra damage to [[Undead]]?
 
* Critical hit: Friendly AoE heal centered around the enemy.
 
* Resisted by: Arcane resistance.

<blue>The tick rate of channeled skills is currently scaled by your weapon speed. This has the side effect of making the resource cost go up, which we’re okay with. It’s consistent with the philosophy that faster speed weapons consume more resource but may do more damage. Channeled skills might still be better with slower weapons though because on a channeled skill, you have as much mobility as you want, so the “mobility” and “overkill” advantages of faster weapons are eroded with channeled abilities, so all you’re left with is increased mana cost for increased damage.</blue>

DoT is no longer associated with an particular damage types, and it comes mostly from skill effects.
  
  
 
===Spell Damage===
 
===Spell Damage===
  
The actual formula for spell damage is one of the biggest changes to [[combat]] in Diablo III. It's been changed to work much like physical damage does; spells now come with a fairly low base damage, much like weapons, and that value is acted upon by attributes, spells, traits, and equipment bonuses, all of which factor in to the final spell damage.  The ratios and relationships in this have changed repeatedly during development, and the final details are not yet finalized.
+
Spells is just another word for "skills," one usually applied to mage-type attacks. This is purely a language convention in Diablo III, with all skills calculating their damage in much the same fashion, whether they are executed with a sword or a fireball. For instance, compare two classic Diablo skills in their function as of [[Patch 1.05]]:
 +
 
 +
Wizard's [[Meteor]]:
 +
* Summon an immense Meteor that plummets from the sky, causing 260% weapon damage as Fire to all enemies it crashes into. The ground it hits is scorched with molten fire that deals 60% weapon damage as Fire over 3 seconds.  
 +
 
 +
Barbarian's [[Frenzy]]
 +
* Swing for 110% weapon damage. Frenzy attack speed increases by 15% with each swing. This effect can stack up to 5 times for a total bonus of 75% attack speed.  
  
Early in Diablo III's development, equipment with +%spell damage was said to be of great importance to mage type characters, who were destined to value it as combat characters do +% weapon damage equipment.  This system evolved during development, and as of January 2012 such equipment is quite rare in the Beta test, with most +damage now delivered by attributes, especially gear with +[[Attack]] stats.
+
Note that the descriptions are essentially identical, with the damage entirely based as a percentage of weapon damage.  
  
 +
 +
===Spell Damage from Equipment===
 +
 +
Early in Diablo III's development, equipment with +%spell damage was of great importance to mage type characters, who were destined to value it as combat characters do +% weapon damage equipment.  This system was modified during development and all sort of +%spell damage was phased out of the game. All skills are now boosted by the same properites; weapon damage, passive skills, and item modifiers.

[[Image:Bosshealth.jpg|thumb|Boss' health]]
+
The display of monster health bars has changed repeatedly during development (as has everything in the [[interface]].) The final system was arrived at by the beta test, with character, pet, and monster health bars able to toggle on or off in the options menu. Most players play with health bars visible, and while it makes for less pretty screenshots, most players value the information display over aesthetics.
The display of monster health bars has changed repeatedly during development (as has everything in the [[interface]].) As of the beta test, the display of regular monster health bars can be toggled on/off. Only [[bosses]] and [[champions]] always show their health bars atop the screen, when they are targeted.
+
 
 +
Normal monsters show their hit points directly over their heads in the battle. Bosses of all types, from Champions up to Act Bosses, display as seen to the right, with a normal small health bar over their head, but a big one with their name atop the center of the screen.
 +
 
 +
These sorts of large displays are always visible during special boss fights in "closed rooms."  Thus no matter how near or far these bosses are from your character, players always know exactly how many hit points they have.  Such bosses also show up with a special icon on the minimap.
  
Special quest event bosses, such as the [[Skeleton King]] or [[Siegebreaker]] show their health bars in a special scrollwork frame, in the top center of the screen for the duration of the battle, even if the character is not currently targeting the boss, or even on the screen with them.

==Target Outline==
  
One of the surprise controversies of Blizzcon 2009 was the [[red target outline]]. A new feature just added to the game was a glowing red outline around the monster being pointed at. This outline was meant to help players identify what they were pointing at on the frequently-crowded and chaotic battle screens of Diablo 3. Most players didn't mind or didn't even notice while playing at the show, but for some at Blizzcon, and for many others viewing screenshots and gameplay movies over the Internet, the red outline was bright and too obvious and distracting.

This became a minor issue of contention, but the D3 Team never wavered in their opinion that the feature was essential.[http://diablo.incgamers.com/blog/comments/jay-wilson-exclusive-full-transcript/] It seems to have been accepted over time, and has been a non issue during the [[Diablo III beta]].

Julian: Yeah in fact that’s a common input that I’ll receive is “Hey this guy’s a fiery this or whatever, but can we make that fire look green?” And that’s where the sort of designer in me has to kind of come out and say, wait a minute if we make fire green all of a sudden it’s a bit of a miscommunication in terms of the gameplay. And so there is a bit of constraint there that, at one point I’m trying to make things look as epic as they can, but at the same time they have to be really clear to the player so that they’re not confused that you know, green fire might mean poison. Then there’s the other part of it which is it’s really easy in my department to make a big mess. We can just clobber the screen with so many effects that you just can’t see the game anymore. So those are really the two constraints we really work with most.</blue>

===Critical Hit Visuals===
+
==In Depth Combat==
 
 
[[Image:Critical-hit2.jpg|thumb|250px|Cold critical hit, with highlighted gore.]]
 
[[Critical hits]] inflict extra damage and/or bonus effects (detailed above). Various skills and items can improve the odds of a critical hit, as well as the damage it deals. Other skills or item effects trigger each time a critical hit is scored, creating an interesting and interconnected system of damage bonuses.
 
 
 
Critical hits existed in Diablo II, but they were indicated only by a small sparkle of white light. That concept has been vastly upgraded in Diablo III. Now, when a [[monster]] takes a "crit" there's a dramatic graphical effect, especially if the death is due to crits. Monsters so slain literally explode, shattering into gory chunks that fly across the screen and litter the ground. These animations are customized for whatever type of damage killed them; flames will be seen on the hunks of meat if the critical was fire-based, sparks rise from lightning, etc. Physical damage crits leave huge slicks of blood and give a battlefield a lovely post-massacre patina.
 
  
* See the [[critical hits]] page for much more detail.

[[Image:Barb-cleave2.jpg|thumb|250px|Cold damage from an axe. {The red-orange slash is the [[Cleave]] skill graphic.]]
 +
The combat in Diablo I and Diablo II was often criticized for being simplistic. Not only could most characters "[[spam]]" the same one or two skills over and over again, this was actually the most effective way to play, in most situations. Diablo III is attempting to change this mechanic in various ways.  
  
 +
In terms of skills, the developers want more skills to be viable in the end game. This is the case and it's created by several factors:
  
==In Depth Combat==
+
* Better balance to skills to allow more play style variety.
 +
* Skill damage scales up with attributes and other equipment.
 +
* No skill points.

Not only could most characters "[[spam]]" the same one or two skills over and over again, this was actually the best way to play, in most situations. Diablo III is attempting to change this mechanic in various ways, most notably the better balance to [[skills]], the way that skill damage scales up with [[attributes]], and the removal of [[skill points]].  
+
As a general design goal, the [[D3 Team]] worked to make combat feel more tactical. Their biggest change was the removal of potions as a major game mechanic. Healing potions remain, but they provide only a partial heal and have a long [[cooldown]] after each use. Players must heal themselves with [[health orbs]], with skills, and with equipment bonuses.
  
As a general design goal, the [[D3 Team]] wants to make combat much more tactical. Diablo III is still a fast-paced, click-intensive Action RPG, but there should be a bit more strategy required than "click 'til dead." [[Jay Wilson]] spoke on the shallowness of combat in D2, and his plans to deepen it in D3 [http://www.1up.com/do/previewPage?pager.offset=0&cId=3172030&p=1 with 1up.com] in December 2008.

::The combat model doesn't have a lot of depth in the previous games. It was very much a "one-skill spam" kind of game, which I think works great for the Normal [difficulty] playthrough. I think most of the audience is just fine with that, and through most of the Normal difficulty, it's going to be like that. But as you go into Nightmare and Hell difficulties, I think that the more serious player will appreciate a game that's a little deeper on the combat-mechanic side.
+
<blue><font color="#FFFFFF">What makes Diablo 3's combat deeper than its predecessors?</font>
 +
Jay Wilson: Combat is as deep as the options the designers give themselves. Whenever you add a new capability to a monster -- potentially something that feels unbeatable -- it's more of an opportunity to expand the depth of your characters so they can respond to those threats.  
  
::'''1up.com: What makes Diablo 3's combat deeper than its predecessors?'''<br>
+
A good example would be if you look at Diablo 2: There were a couple of problems with just the power of the characters and the way they were made powerful. A player could run faster than any monster, so you could escape just about any threat. You had endless health and resource -- by resource, I mean mana -- because of potions. And you had the Town Portal, which could instantly get you out of any problem. Those were incredibly powerful mechanics to escape danger and were not class-specific. So every kind of class really had no need for anything like an escape skill or reactionary ability. They simply needed to attack, and if they ever got in over their heads, they simply ran away or drank potions. And it's the same response across the board.

I really distinguish the difference between complexity and depth; to me, complexity is adding more buttons, while depth is making a single button more powerful and versatile. So that's always been our goal -- reducing the amount of controls while making each button mean more. So that's one of the reasons we added the Hotbar; it's one of the reasons why we avoided the potion-health system. And when people play the game, they may not notice this next point that much, but we leveled out the movement speed somewhat so that the player moves at a more reasonable rate compared to the monsters.

The disincentives to spamming the same skill over and over again are not very visible in the beta test, such things are not meant to come strongly into play until higher difficulty levels
 
 
 
==Weapon Damage on Skills==
 
 
The damage of all skills and spells in Diablo III are determined by a character's attributes (chiefly Attack) and their weapon damage. This include spells, such as [[Magic Missile]], [[Poison Dart]], and all the rest. This change equalizes equipment needs, as now mage classes need to hunt for big damage weapons just as combat classes always have.
 
 
[[Image:Bash.png|thumb|300px|Bash speed and damage stem from item stats and attributes.]]
 
Casting speed is also affected by weapon choice, just as attack speed always has been. As a result a Wizard or Witch Doctor can use a large two-handed weapon, and their spell damage will increase, but they will generally suffer a much slower casting rate as a result. The more appropriate mage weapons, such as wands for Wizards and daggers for Witch Doctors, also tend to have appropriate bonus stats, such as + to their resource regen rates, that will never spawn on combat weapons.
 
 
[[Off-hand weapons]] are another important factor. Wizards can use [[Orbs]], Witch Doctors can use [[Totems]], and Demon Hunters can use [[Quivers]], all in their off-hand slot along with a regular weapon. These off hand items tend to spawn with very useful bonuses, and as a result a Wizard with a good Orb and a good [[Wand]] will almost always do more damage than the same Wizard with a big damage two-handed weapon. Plus the Wand and Orb will have more useful bonuses.
 
 
How well this ratio will balance out in the late game is unknown, but as of the beta, a Wizard or Witch Doctor is always better off with a one-handed weapon and their class-specific off-hand item than they would be with any available two-handed weapon.
 
 
 
==Skill Modifiers for "on Hit" stats==
 
Items can often have a stat "on Hit" that is applied every time you hit with that skill. Because the speeds and number of enemies hit with each skill are different, Blizzard implemented a modifier to each skill. For example, Life on Hit +20 will not yield exactly 20 life on most skills. A list of skills and their modifiers can be found here: [[On Hit Modifiers]].
 
 
 
==Dual wielding and Weapon Damage when using Skills==
 
[[Image:Broadaxe.png|thumb|300px|The base raw Damage on a Weapon is NOT the % Weapon Damage that Skills refer to.]]
 
When a dual-wielding character performs a skill that is based on % weapon damage, the character will alternate hits with the two equipped weapons. Unlike Diablo 2, Diablo 3 is smart enough to calculate everything individually, bonuses aren't simply added up between two weapons and applied equally with either one.
 
 
[[Damage Over Time]], for instance, is calculated individually by whichever weapon delivered the hit, with the "tick rate" of the DoT determined by the attack speed of the weapon that delivered it. Earlier in D3's development, dual wielding was said to grant an inherent bonus to attack speed, but this feature can not be discerned in the beta test.
 
  
  

Latest revision as of 15:44, 2 December 2012

Every class in Diablo III is a DPS class; all are capable of prolifically slaying the enemies, whether by spells, skills, brute force, or a clever combination of techniques.

Aspects of combat are addressed throughout this wiki. Weapons and skills are detailed, monsters are described, strategies are promoted, and more. This page covers the basics of combat, and how the game is designed to facilitate it.

Combat is simplified in Diablo III, with skills factoring in weapon damage, attack rate, main stat, critical hit damage and critical hit chance as the chief factors. All elemental types of damage are calculated the same as physical damage, and there is no real to hit factor, nor is there much variety between weapon types, with no special bonuses, such as blunt weapons dealing higher damage to the undead (as was the case in Diablo 1 and Diablo 2.)


Damage Types[edit | edit source]

While damage types were a major feature during Diablo III's development, this aspect of combat was simplified before release and all variety between different damage types was removed from the game.. The graphics remain different, but players often refer to the different elemental types as "red damage," "green damage" and so forth, since the color variations are purely cosmetic. Jay Wilson explained this in regards to poison damage shortly after release:[1]

How do the witch doctor posion mechanics work, do they reset when added i.e. like the warrior rend. –sebducker Poison in D3 does not act like D2. It’s not a guaranteed dot. If a skill has a DoT reapplying refreshes duration unless noted. Some skills have DOT mechanics, and some of those skills use poison damage, but poison damage does not DOT by default. I’ll repeat: poison damage does not work like D2. It does not apply a persistent effect, it’s a type of damage like fire or holy. –JayWilson

All elemental damages are calculated just as if they were physical damage, with a character's main stat, weapon damage, and skill damage adding up no matter what types of damage they are. For instance, a Wizard might use a wand with Arcane damage to cast Meteor (fire damage), and while the resulting attack would look like the Meteor skill, it wouldn't be fire or arcane damage in any effective way. It's just damage, exactly as if the wand had physical or fire or lightning damage.


Critical Hit Effects[edit | edit source]

Axes with cold and lightning damage show their graphics.

During development, each type of damage was going to create a special bonus effect when a critical hit was scored. This feature was removed from the game shortly before release when all damage types were simplified. The only remaining effect is visual; monsters that die to poison damage leave gas-smoking green corpses, monsters that die to lightning appear charred black and crispy, fire damage will set corpses on fire, etc. These effects are amplified when monsters die to a critical hit of that damage type, and they explode in flames, or lightning-crackling chunks, etc.

All very pretty, but without any strategic function in Diablo III.

As in previous games in the series, there are numerous types of damage in Diablo III. Various spells, skills, runes, and weapons channel their destructive might into one (or more) types of damage. Characters and monsters counter these attacks with equivalent types of resistance and immunities, and players must find the right balance of each if they wish to succeed in their battles.

The following lists the damage types and their critical hit effects, but these are purely visual without any special function.

Physical Damage: No special graphic.

  • Critical hit deaths may explode in novas of blood and gore.

Arcane Damage: Purple in coloration. Dead monsters with glow with a purple light.

  • Critical hits were going to "silence" targets, which would have prevented summoners from resurrect or casting buffs on monsters. This feature was removed during development.

Cold Damage: Blue in coloration. Targets may be chilled and slowed, and will turn blue and may shatter upon death.

  • Critical hits were set to freeze targets before this feature was removed.

Fire Damage: Red in coloration, often with flames. Dead enemies may appear blackened or charred.

  • Critical hits with fire were set to deal a DoT effect adding fire damage, but this feature was removed.

Lightning Damage: White-blue in coloration. Dead enemies will appear crisped and dried up.

  • Critical hits were set to stun targets before this feature was removed. During pre-release testing skills such as Electrocute were highly effective due to their ability to repeatedly stun enemies.

Holy Damage: White in coloration, this damage type is not found on weapons, but is dealt by some Monk skills.

  • Critical hits were set to provide an AoE heal to friendly nearby targets, before that feature was removed from the game.
    • Resisted by: Arcane resistance is tabbed for resisting Holy damage. This is only a factor in PvP, since no monsters deal holy damage.

Disease Damage: Green in coloration. Formerly known as "Toxic" this damage will turn enemies green and cause puffs of green gas to rise from their corpses.

  • Resisted by Poison resistance.
    • Diseased units were set to suffer a damage debuff; they take more damage and deal less, but this was removed during game development.

Poison Damage: Green in coloration. (Acid damage is poison.) (Poison and Disease are similar, but not the same.[2])

  • Poison does not "poison" targets with a DoT effect. It's just another type of direct damage in Diablo 3.



Damage Over Time[edit | edit source]

The DoT mechanic is much expanded and complicated in Diablo 3. No longer is the equation simply "X damage per second over Y seconds." In December 2011, Bashiok delivered an informative forum post on the subject, which you can read below:[3]

The tick rate of channeled skills is currently scaled by your weapon speed. This has the side effect of making the resource cost go up, which we’re okay with. It’s consistent with the philosophy that faster speed weapons consume more resource but may do more damage. Channeled skills might still be better with slower weapons though because on a channeled skill, you have as much mobility as you want, so the “mobility” and “overkill” advantages of faster weapons are eroded with channeled abilities, so all you’re left with is increased mana cost for increased damage.

DoT is no longer associated with an particular damage types, and it comes mostly from skill effects.


Spell Damage[edit | edit source]

Spells is just another word for "skills," one usually applied to mage-type attacks. This is purely a language convention in Diablo III, with all skills calculating their damage in much the same fashion, whether they are executed with a sword or a fireball. For instance, compare two classic Diablo skills in their function as of Patch 1.05:

Wizard's Meteor:

  • Summon an immense Meteor that plummets from the sky, causing 260% weapon damage as Fire to all enemies it crashes into. The ground it hits is scorched with molten fire that deals 60% weapon damage as Fire over 3 seconds.

Barbarian's Frenzy

  • Swing for 110% weapon damage. Frenzy attack speed increases by 15% with each swing. This effect can stack up to 5 times for a total bonus of 75% attack speed.

Note that the descriptions are essentially identical, with the damage entirely based as a percentage of weapon damage.


Spell Damage from Equipment[edit | edit source]

Early in Diablo III's development, equipment with +%spell damage was of great importance to mage type characters, who were destined to value it as combat characters do +% weapon damage equipment. This system was modified during development and all sort of +%spell damage was phased out of the game. All skills are now boosted by the same properites; weapon damage, passive skills, and item modifiers.

Health Bar[edit | edit source]

The display of monster health bars has changed repeatedly during development (as has everything in the interface.) The final system was arrived at by the beta test, with character, pet, and monster health bars able to toggle on or off in the options menu. Most players play with health bars visible, and while it makes for less pretty screenshots, most players value the information display over aesthetics.

Normal monsters show their hit points directly over their heads in the battle. Bosses of all types, from Champions up to Act Bosses, display as seen to the right, with a normal small health bar over their head, but a big one with their name atop the center of the screen.

These sorts of large displays are always visible during special boss fights in "closed rooms." Thus no matter how near or far these bosses are from your character, players always know exactly how many hit points they have. Such bosses also show up with a special icon on the minimap.


Target Outline[edit | edit source]

One of the surprise controversies of Blizzcon 2009 was the red target outline. A new feature just added to the game was a glowing red outline around the monster being pointed at. This outline was meant to help players identify what they were pointing at on the frequently-crowded and chaotic battle screens of Diablo 3. Most players didn't mind or didn't even notice while playing at the show, but players who only saw the RTO in screenshots or videos found it distracting.

This became a minor issue of contention, but the D3 Team never wavered in their opinion that the feature was essential[4] and fans had no problem with it once the beta began and then moved into release.


Information Through Graphics[edit | edit source]

The visuals tied to damage types are meant to add eye candy, but also to inform the player about events occurring on the screen. As Julian Love explained during BlizzCast #8, in March 2009. [5]

Bashiok: A lot of the effects that you make factor in to the abilities that the characters are using, so fire and arcane and all that stuff, but in the world of Diablo it seems like there are very specific magic types that exist... it is actually a pretty broad spectrum, but is there any limitation there to what you can do with different damage types?


Julian: Yeah in fact that’s a common input that I’ll receive is “Hey this guy’s a fiery this or whatever, but can we make that fire look green?” And that’s where the sort of designer in me has to kind of come out and say, wait a minute if we make fire green all of a sudden it’s a bit of a miscommunication in terms of the gameplay. And so there is a bit of constraint there that, at one point I’m trying to make things look as epic as they can, but at the same time they have to be really clear to the player so that they’re not confused that you know, green fire might mean poison. Then there’s the other part of it which is it’s really easy in my department to make a big mess. We can just clobber the screen with so many effects that you just can’t see the game anymore. So those are really the two constraints we really work with most.


In Depth Combat[edit | edit source]

Cold damage from an axe. {The red-orange slash is the Cleave skill graphic.

The combat in Diablo I and Diablo II was often criticized for being simplistic. Not only could most characters "spam" the same one or two skills over and over again, this was actually the most effective way to play, in most situations. Diablo III is attempting to change this mechanic in various ways.

In terms of skills, the developers want more skills to be viable in the end game. This is the case and it's created by several factors:

  • Better balance to skills to allow more play style variety.
  • Skill damage scales up with attributes and other equipment.
  • No skill points.

As a general design goal, the D3 Team worked to make combat feel more tactical. Their biggest change was the removal of potions as a major game mechanic. Healing potions remain, but they provide only a partial heal and have a long cooldown after each use. Players must heal themselves with health orbs, with skills, and with equipment bonuses.

Jay Wilson spoke on this design goal early in development with 1up.com in December 2008.

What makes Diablo 3's combat deeper than its predecessors?

Jay Wilson: Combat is as deep as the options the designers give themselves. Whenever you add a new capability to a monster -- potentially something that feels unbeatable -- it's more of an opportunity to expand the depth of your characters so they can respond to those threats.

A good example would be if you look at Diablo 2: There were a couple of problems with just the power of the characters and the way they were made powerful. A player could run faster than any monster, so you could escape just about any threat. You had endless health and resource -- by resource, I mean mana -- because of potions. And you had the Town Portal, which could instantly get you out of any problem. Those were incredibly powerful mechanics to escape danger and were not class-specific. So every kind of class really had no need for anything like an escape skill or reactionary ability. They simply needed to attack, and if they ever got in over their heads, they simply ran away or drank potions. And it's the same response across the board.

So one of the things we focused on is that response -- 1) setting up scenarios where the players can't easily get out of danger without the use of class-specific skills, and 2) giving them really simple controls to use a broader range of skills without making the game that much more complex to play. I really distinguish the difference between complexity and depth; to me, complexity is adding more buttons, while depth is making a single button more powerful and versatile. So that's always been our goal -- reducing the amount of controls while making each button mean more.

Most of Jay's design goals from 2008 are evident in the finished game, though changes like the removal of town portals, much slower character foot speed, long cooldowns after using health potions, and more.
