Attack damage is the amount of damage a unit is shown to deal with a regular attack. A unit's total attack damage is the sum of its main attack damage (white) and bonus attack damage (green). Attack damage is modified by many different effects in the game and ends up going through a number of steps in order to determine how much damage an attack actually deals as its overall or total attack damage.

Total attack damage[edit]

Properties of a level 1 Sniper with a Wraith Band: Sniper's base attack damage varies by 6; main attack damage is white, bonus attack damage green.

Calculating the total damage of an attack after all is said and done involves using many different multipliers and values. Total attack damage is synonymous with how much health a target immediately loses as a direct result of the attack. Some on-hit effects that are not affected by critical strike are still considered part of attack damage, and some are not.

Formula:

Damage =
{ [Main Attack Damage × (1 + Σ Percentage Bonuses) + Flat Bonuses]
× Crit Multiplier - Blocked Damage }
× Armor Multipliers
× General Damage Multipliers

Base attack damage[edit]

Base attack damage is the part of the main attack damage that stays the same throughout a game. It consists of two values, a minimum and maximum amount. Every time an attack is issued, a random value between these two extremes is chosen to help decide the damage output. The most extreme hero example of this is Chaos Knight, with base attack damage ranging between 29 and 59, causing his damage output to be somewhat unpredictable (or at least much less predictable than other heroes). This range of 30 is always part of his attack calculations, no matter how many attributes or how much bonus attack damage he acquires.

Main attack damage[edit]

Main attack damage is the damage value shown in white numbers on a hero's statistics consisting of the base attack damage with the damage granted by a hero's primary attribute on top. A hero's main attack damage can only be increased by raising its primary attribute, or by very few specific abilities. Attribute points can be acquired by leveling up, or by using specific items, abilities, or talents that raise attributes.

Formula:

main attack damage = base attack damage + total primary attribute points + ability bonuses.

Bonus attack damage[edit]

Bonus attack damage comprises the green number next to main attack damage. It comes in two types:

Formula

bonus attack damage = sum of bonuses + sum of reductions.


Critical strike multiplier[edit]

Critical Strike is an attack modifier that multiplies the total attack damage certain factor. If an attack activates more than one critical strike, only the highest multiplier is applied.

Main Article: Critical Strike

Blocked damage[edit]

Damage Block is a passive ability that gives the unit a chance to block a certain number of physical damage from an attack. If an attack activates more than one damage block ability, only the highest block value is applied.

Main Article: Damage Block

Armor value multiplier[edit]

The target's armor influences the attack damage by a factor that asymptotically lies between 0 and 2 and is 1 for a target that has no armor.

Formula

damage multiplier = 1 - ((0.052 × armor) ÷ (0.9 + 0.048 × |armor|)).


Main Article: Armor

Armor type multiplier[edit]

Depending on the combination of the attack damage type and armor types, an armor type multiplier modulates the attack damage.

General damage multipliers[edit]

Main Article: Damage manipulation

A few abilities such as Bristleback and Dispersion modify all incoming damage, including attack damage. Bulwark reduces attack damage specifically.

Attack damage types[edit]

There are several different types of attack damage, which determine how much damage a unit's attack deals against certain armor types. Each of the 4 different attack types deals either reduced, increased, or unchanged damage against each of the armor types, on top of it being also manipulated by the armor value of the target.

Example
A hero with 100 attack damage attacking a siege unit which has 0 armor deals 50 damage to it, because the attack type "hero" deals 50% less damage against the armor type "structure", which is the siege creeps' and all buildings' armor type. If the siege creep would gain 5 armor, the 100 damage attack would deal (100 * 0.8 * 0.5) = 40 damage. The same attack would deal 80 damage to a unit with any other armor type, since attack type hero deals full damage to them.

This table shows how much damage each attack damage type deals against each armor type, and which units use which attack damage type:

Attack Damage Type Used by Armor Type
Hero Basic Structure
Hero Heroes, Ancient Black Dragon, Ancient Granite Golem, Ancient Prowler Shaman, Ancient Thunderhide, Boar, Centaur Conqueror, Dark Troll Summoner, Death Ward, Earth, Familiar, Fire, Forged Spirit, Hellbear Smasher, Hellbear, Roshan, Satyr Tormenter, Skeleton Archer, Spiderling, Storm, Warlock's Golem, Wildwing Ripper, Wraith King Skeleton 100% 100% 50%
Basic Alpha Wolf, Ancient Prowler Acolyte, Ancient Rock Golem, Ancient Rumblehide, Centaur Courser, Eidolon, Fell Spirit, Greater Treant, Kobold Foreman, Kobold Soldier, Kobold, Lycan Wolf (Aghanim's Scepter), Lycan Wolf, Mega Melee Creep, Melee Creep, Mud Golem, Ogre Bruiser, Ogre Frostmage, Satyr Mindstealer, Shard Golem, Skeleton Warrior, Spiderite, Spirit Bear, Super Melee Creep, Treant, Wildwing 75% 100% 70%
Pierce Ancient Black Drake, Ghost, Giant Wolf, Harpy Scout, Harpy Stormcrafter, Hill Troll Berserker, Hill Troll Priest, Hill Troll, Mega Ranged Creep, Necronomicon Archer, Necronomicon Warrior, Plague Ward, Ranged Creep, Satyr Banisher, Serpent Ward, Super Ranged Creep, Undying Zombie, Vhoul Assassin 50% 150% 35%
Siege Fountain, Siege Creep, Super Siege Creep, Tier 1 Tower, Tier 2 Tower, Tier 3 Tower, Tier 4 Tower 85% 100% 250%

Instant attacks[edit]

Several abilities make use of the hero's regular attacks. However, these attacks are instant. This means they do not use the hero's attack animation, are independent from attack speed and ignore the regular downtime between attacks. If an instant attack is performed by a ranged hero, it still uses their regular attack projectile for the attack, unless it is set not to. If an instant attack occurs while already attacking an enemy normally, it does not interfere with the regular attack. They do not interfere with any other actions of the hero either, meaning they do not interrupt movement, do not cancel spell casts and do not stop channeling spells of the hero.

Since instant attacks do not use attack animations and jump straight to the attack point, they cannot proc effects which react on the start of an attack, like Untouchable or Moment of Courage. However, they can proc effects which react on attack hit, such as Counter Helix and Retaliate, although there are some exceptions to this. Instant attacks may proc on-hit effects only when they are allowed to. An instant attack which is not allowed to proc attack modifiers is not allowed to proc on-hit effects either. Just like regular attacks, instant attacks also cause the attacking hero to get revealed if attacking from the Fog of War.

The following abilities make use of instant attacks:

1 Requires Aghanim's Scepter icon.png Aghanim's Scepter.

2 These instant attacks may not proc any attack modifiers or on-hit effects.

3 Requires Talent talent.

4 Split Shot may not proc any attack modifiers or on-hit effects, unless the required talent is chosen.

5 Number of instant attacks is dependent on Juggernauts attack speed.

Conditional bonus[edit]

These abilities give direct attack damage bonuses under certain circumstances. Due to this, they do not display their damage bonus in the HUD. Their damage type can also vary and is not necessarily physical; nonetheless, they still count as attack damage since their damage is dealt in one instance together with a unit's attack damage. This means they are affected by armor type (even when dealing magical damage), but not by spell damage amplification.
