Damage Types

 

Attack damage ( $A$ ) 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 and can be 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

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

Calculating the total damage of an attack 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.

Total Attack Damage Sources

• Total Attack Damage can be defined as
  • Base and Main Value
    • ± Base Attack Damage Values (× Multiplier)
    • × % Bonus Attack Damage Multiplier
    • ± Flat Bonus Attack Damage Values
    • × Critical Strike Multiplier
  • ± Instant Attack Damage Bonus (× Multiplier)
  • ± × Conditional Bonuses
  • − Damage Block
  • × Attack Class Multiplier
  • × Damage Manipulation

The following abilities reduce the affected unit's damage before damage block is applied.

• Arc Warden – Tempest Double⁴
• Bane – Enfeeble
• Dragon Knight – Breathe Fire
• Giant Wolf – Intimidate
• Hoodwink – Acorn Shot³

⁴ Total attack damage is only reduced for the Tempest Double if the penalty distance is exceeded or Arc Warden is dead.

Attribute points can be acquired by leveling up, or by using specific items, abilities, or talents that grants bonus attributes.

Base Attack Damage

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 the minimum and maximum is chosen to help decide the damage output.

The most extreme hero example of this is Chaos Knight, with his base attack damage ranging between 24 – 54, causing his damage output to be somewhat unpredictable. This range of 30 is always part of his attack calculations, no matter how many attributes or how much bonus attack damage he acquires.

Base Attack Damage Increasing Sources

• Arc Warden – Magnetic Field (Dire)
• Terrorblade – Metamorphosis
• Tiny – Tree Grab
• Tiny – Grow

Base Attack Damage Bonus: Varies

• Grants the hero base attack damage bonus.
  • As such, it is affected by percentage-based damage increasing or reducing effects.

• The following values exist:
  • 15/20/25/30/40/45/50/100

The following heroes have a talent that grants them base attack damage.

Base Damage	+50	+30

Bonus Attack Damage

Bonus attack damage is the attack damage value shown in green numbers with a plus on the left, right after the white attack damage number on a unit's statistics. Whenever a bonus attack damage granting item or ability shows a +Attack Damage, e.g. Blades of Attack +9 Damage, it increases the bonus attack damage of the affected unit.

Probably the most important difference between main and bonus attack damage is that illusions only benefit from main attack damage, although their HUD still shows the bonus armor just like on other heroes, to make them less obvious to the enemy.

There are two types of bonus attack damage:

• Flat Bonuses: Adds a flat number of damage to the unit's damage total (e.g. Phase Boots etc.).
• Main Attack Damage Percentage Bonuses: Adds an amount of bonus attack damage equal to a percentage of the affected unit's main attack damage (e.g. Vladmir's Offering, Packleader's Aura etc.). While bonus attack damage is usually positive values, it can also use a negative value to reduce a unit's net attack damage (e.g. Static Link etc.).

Bonus Attack Damage is defined as

Bonus Attack Damage = (Main Attack Damage × $\prod_{i=1}^{n}$(1 + Bonus Value Modifiers _i) + Flat Bonus Values

Attack Damage Bonus: Varies

• Grants the hero a flat attack damage bonus.
  • As such, it is not affected by percentage-based damage increasing or reducing effects.

• The following values exist:

Reducing Sources

Abilities Applying Bonus Attack Damage Reductions

• Razor – Static Link

Critical Strike Multiplier

Wraith King performing a critical strike.
The red number displays the resulting physical damage before reductions.

Main Article: Critical Strike

If an attack procs more than one source of critical strike, only the highest multiplier is applied.

Damage Block

Main Article: Damage Block

Axe blocking physical attack damage with Vanguard.
The ochre number displays the total amount of damage blocked.

Driven by MODIFIER_PROPERTY_PHYSICAL_CONSTANT_BLOCK.

Physical damage block reduces any physical damage a unit takes from attacks or from cleave, with the exception of damage dealt by attacks from ward-type units. Physical damage block offers no protection against spells, with only a few exceptions.

Physical damage block triggers after Mana Shield, but before all other damage manipulation. This means that the higher the unit's armor is, the less actual reduction is provided by damage block. However, the effectiveness of damage block is only meaningful in relation to the attacker's damage. See total attack damage for detailed examples with calculation.

When physical damage block procs, an ocher-colored negative number pops up on the unit, with a shield icon on the right side of the -x number. This number shows the exact amount of damage blocked.

Chanced-based physical damage block uses pseudo-random distribution. If an attack activates more than one damage block ability, only the highest block value is applied.

All Melee heroes have an innate  Damage Block ability, which has a 50% chance to block 16 damage.

Damage Manipulation

Main Articles: Armor and Damage Manipulation

Attack Classes

There are currently 3 different classes of attack damage types (also known as 'Attack Classes) that manipulate the damage value of a unit's attack against certain other unit types. Each attack classes deal either reduced, increased, or unchanged damage against heroes, creeps (i.e. non-hero units), and buildings, before all armor reduction values.

The attack classes are represented by 3 abilities visible in the unit's HUD. If a unit does not have any of these 3 abilities, their attacks deal 100% damage and are only altered by the target's armor and other damage manipulators.

These abilities are not acquirable via Devour.

Attack Damage Dealt = Total Attack Damage × Attack Class × Damage Manipulation

Instant Attacks

Instant Attacks are abilities that uses the hero's regular attack damage values as ability damage to the target unit(s) or area. Instant Attacks do not use the hero's attack animation, are independent from attack speed, and ignores the regular downtime between attacks. Certain abilities that deal instant attack damage are not affected by evasion. 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 attacks. Instant Attacks do not interfere with any other actions of the hero either, meaning they neither interrupt movement, nor cancel ability casts nor stop channeling abilities.

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 (e.g. Untouchable or Moment of Courage). However, they can proc effects which react on attack hit (e.g. Counter Helix or 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. Evasion and blind fully work against instant attacks. Just like regular attacks, most instant attacks also cause the attacking hero to get revealed under Disguise and/or when attacking from the Fog of War unless stated in their respective ability notes.

Attack-based Projectiles

Some abilities generate projectiles that are based on an attack, but are technically not an attack. These abilities' projectiles use the source's attack projectile, and deal damage based on the attacking unit's attack damage, and have their damage flagged as attack damage as well, but are not counted as attacks otherwise. Instead, they are treated like regular ability projectiles (like e.g. Magic Missile), and therefore cannot trigger attack modifier or on-hit effects, ignore evasion and blind, and do not reveal the attacking units through the Fog of War. This also means that these abilities continue to use projectiles even when their source is a melee hero.
