The basic building blocks for your character are your Attributes. They determine your physical and mental aptitude.
The five attributes that define one's character are listed below. They are primary attributes that influence characteristics.
- Increases your attack power with melee weapons.
- Increases the amount of damage you can block with a shield.
Strength does not affect critical hit chances at all. Strength does not improve your chance to block, but rather the amount of damage blocked when you succeed. This amount is determined by strength and by the block value of your shield.
- Increases your attack power with ranged weapons (not including Wands).
- Increases your armor by 2 per point.
- Increases your chance to score a critical hit with a weapon.
- Increases your chance to dodge attacks.
- Rogues gain a stronger bonus to dodge from agility than other classes.
- A useful formula for calculating the contribution of agility is AEP - Agility Equivalence Points.
From the Developers
- Increases Armor Class by 2 for every point of AGI.
- Increases the chance of a critical hit with melee and ranged attacks. The amount of the increase is dependant on both class and level. For most level 60 character classes, approximately 20 points of AGI will increase your critical hit chance by approximately 1%. Rogues require 29 AGI for an additional 1% critical hit chance, and Hunters require 53 AGI for an additional 1% critical hit chance, but both of these classes also gain attack power from agility and the items available to them typically have much higher amounts of AGI.
- Increases the chance to dodge an attack. The amount increased is dependant on both class and level. For most level 60 character classes, approximately 20 points of AGI will increase your chance to dodge by approximately 1%. Rogues only require 14.5 AGI for an additional 1% dodge chance. Hunters require 26.5 AGI for an additional 1% dodge chance, but Hunters typically have a high amount of agility, as well as an Aspect spell that further increases their chance to dodge attacks.
- Increases health points. Each point of Stamina gives you an additional 10 HP.
- The first 20 points of Stamina grants only 1 health point.
This can be seen as you create a new level 1 warrior. The warrior has 60 health, and 22 Stamina, this grants the warrior 40 health bonus to his already existing 20 base health.
- Increases the rate at which you learn weapon skills. (Some people claimed here that it also increases the rate at which you learn other skills, including tradeskills, but Blizzard explicitly states "weapon skills" (source here). Until a source is given for any other claim, we should stick to Blizzard's words.)
- Increases your Mana points. Each point of intellect gives you 15 Mana points.
- Increases your chance to score a critical hit with spells. For mages, at level 60, 59.5 points of Intellect equal 1% chance to crit with spells, varies depending on class.(See Talshuler's Int Research)
- A recent post by Tseric gave the exact figures at level 60 for spell crit for all casters except paladins, they are as follows:
|Class||Expected Int at 60||Int per 1% crit chance|
- Also see Spirit for comparision to mana/ 5 second gear.
- Increases health and mana regeneration. Spirit affects all characters' mana and hit point regeneration rates in and out of combat.
- By default health will not regenerate in combat unless your race is Troll or you have certain types of spells or potions in effect (buffs).
- By default mana will not regenerate in a period of 5 seconds after casting a spell.
- A Priest with the appropriate talents can receive a spell damage and healing bonus of up to 25% of their total spirit.

The general rule of thumb on how base statistics affect DPS capability is as follows:
- Strength will always contribute to the physical melee DPS for all classes.
- Rogues and Hunters can also use Agility in addition to Strength to increase their base physical melee DPS. Each point of Agility will contribute equally as a point of Strength.
- Druids in Cat Form can also utilize Agility to increase their base physical melee DPS. However, each point of Strength contributes twice the amount of DPS as a point of Agility.
- Agility is the only primary statistic to affect physical ranged DPS (bows, guns, throwing weapons) for all classes capable of using them. This becomes especially important for Hunters.
- Wand damage is not affected by a primary statistic.
See also: Formulas:Attack Power for exact calculations.
(Note - This is a generalization for base DPS only. Damage modifiers such as critical chance is not considered.)
- Agility will increase the chance to score a critical hit with both phsyical ranged and melee damage for all classes. See the Agility section for specifics.
- Intellect will increase the chance to score a critical hit with a spell. For a Mage at level 60 the rate is 1% per 59.5 points in intelligence.
- Agility will determine a character's chance to dodge an attack. Rogues gain a much stronger bonus to dodge than other classes.
