Heroes of the Storm Wiki

Statistics are the numerical measurements of the Abilities of Heroes. All Heroes have statistics which are increased by leveling through gaining Experience, as well as by selecting Talents. Some Abilities can also grant temporary bonus statistics.

Basic Attack[]

Basic Attacks (also called AA - Auto Attack) are the attacks that the Hero will perform after clicking Right Mouse Button on the target. Attack stats improve a Hero's Basic Attack and determine how strong it is. Some Assassin Heroes benefit greatly from increases to their attack stats.

  • Attack damage icon.png Attack Damage - the amount of damage a Hero does when they attack an enemy with their Basic Attack.
  • Attack range icon.png Attack Range - the range at which a Hero can use their Basic Attack.
  • Attack speed icon.png Attack Speed - the speed at which a Hero can use their Basic Attack, in attacks per second.
  • Attack DPS - damage per second using Basic Attacks. Calculated as Attack Damage x Attack Speed.


Every Hero has their own diverse Abilities. Ability stats improve a Hero's abilities and allow them to use them more effectively. Healers, and some Assassin Heroes, benefit greatly from increases to their Ability stats.

  • Resources - Most Heroes have a resource that limits how frequently they can use abilities (in addition to individual cooldowns). A Hero cannot use an Ability without having the required amount of their resource.
    • Unitstatus icon mana.png Mana - Mana is the most common resource Heroes use to cast abilities.
    • Mana regen - the rate at which a Hero regenerates Mana passively, in Mana per second.
  • Spell power icon.png Spell Power - the amount that a hero's Spell Damage is increased by, in percentage of the base damage.
  • Cooldown - time needed before the Ability can be used again.


Defensive stats improve a Hero's ability to take damage. Tank and Bruiser Heroes benefit greatly from increases to their defensive stats.

  • Unitstatus icon health.png Health - the maximum number of Health Points a Hero has.
  • Health regen - the rate at which a Hero regenerates Health Points passively, in Health Points per second.
  • Healing - Healing is a game mechanic to restore a unit's Health.
    • Lifesteal - Lifesteal is a form of self-healing derived from damaging the enemy.
  • Shields - Shields are a bonus layer of defense a hero has on top of their Health.
  • Physical armor icon.png Armor - Armor is a numerical representation of a given Hero's ability to mitigate damage. Each point of Armor is equal to a 1% reduction in damage relative to having 0 Armor.


Utility stats improve Heroes in all other ways.

Status Effects[]

Main article: Status Effect

Status effects are conditions that affect targets for a certain period of time. The effects are inflicted usually by an Ability.


A Buff is a general term that refers to any positive effect with a duration. Effects that improve one's damage output, prevent damage, or increase Movement Speed are examples of buffs. The inverse is called a debuff.
