Armor is a stat that reduces (or increases, if negative) physical damage a unit takes from abilities and attacks. Every unit is capable of gaining or losing armor, and most units start with a small amount of base armor, some even starting with negative armor. A hero's armor can be passively increased with Agility attribute symbol agility via leveling up, certain items, Talent talents and some abilities. Armor of any unit can also be temporarily increased or reduced with some abilities.

Each point of Agility attribute symbol agility increases a hero's armor by 0.167 or .

Base Armor[]

Base armor is the part of the main armor that never changes throughout a game. It consists of one fixed value set for each unit individually. The base armor of a unit can be a negative number. Since only heroes have agility, the HUD of all non-hero units shows their base armor.

Main Armor[]

Main armor is the armor value shown in white numbers near the shield icon in the HUD, consisting of base armor and the armor granted by a hero's agility. The only way to improve a hero's main armor is to increase its Agility attribute symbol agility, which is gained by leveling up, acquiring certain items, or with the help of certain abilities.

Attribute Bonus Main Armor
Agility attribute symbol Agility +0.167

The main armor is defined as

Main Armor = (Base Armor + (Σ Agility Current)/6) × (1 - Armor Negation)

Main Armor Sources[]

These abilities directly manipulate Agility attribute symbol agility points and therefore it affects main armor instead.

1 Requires Talent talent.
2a Requires Aghanim's Scepter icon Aghanim's Scepter.
2b Requires Aghanim's Shard icon Aghanim's Shard.
3 Only affects Agility attribute symbol agility and Universal attribute symbol universal heroes.

Armor Negating Sources[]

Some abilities negate or ignore a unit's main armor by reducing or increasing armor based on the unit's main armor, effectively removing a percentage of the armor on the target. Armor negation only affects the armor value of units, their defense class is unaffected and still reduces damage normally.

Armor Negating Sources
  • Marksmanship icon
    Proc Chance: 15%/20%/25%
    Main Armor Reduction: 100%
    Has a chance to completely ignore the target's main armor value on attack, dealing damage as if they had 0 main armor.
  • Natural Order icon
    Base Armor Reduction: 40%/60%/80%/100%
    The effects is provided by an aura, affects nearby enemies. The reduction is based on the enemies' main armor. The debuff lingers for 1 second.

Terrorblade minimap icon Terrorblade has a total of Expression error: Unexpected < operator. main armor in this example.

Bonus Armor[]

Bonus armor is the armor value shown in green numbers with a plus on the left, right after the white armor number on a unit's statistics. Whenever an armor granting item or armor increasing ability shows a +Value Armor, e.g. Blade Mail icon Blade Mail +7 Armor, it increases the bonus armor of the affected unit.

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

Sources of multiple bonus armor stack additively.

Armor Negation sources do not affect bonus armor.

Example1
How much total armor does a Terrorblade minimap icon Terrorblade with a Blade of Alacrity icon Blade of Alacrity and Blade Mail icon Blade Mail at Level 8 have?
Base Armor: Lua error in Module:Show at line 24: attempt to index field '?' (a nil value).

Pure Damage[]

Main Articles: Damage Types and HP Removal

Pure Damage is a damage type that is not reduced by Armor or Magic Resistance. It is also not amplified by magical damage amplification abilities, fully ignores Armor and Damage Block. It does not affect invulnerable units.

There are a few sources that can manipulate Pure Damage, with Dispersion icon Dispersion being one of them. This mechanic is called damage reduction. Pure damage affects units with Spell Immunity (because spell immunity does not block damage), but that does not mean that an ability that deals pure damage is able to target spell immune units.

Abilities Based on Armor[]

  • Battle Hunger icon
    Armor as Damage per Second: 100% (Talent 200%)
    Non-Hero Armor Multiplier: 0.5
    Deals damage based on the hero's armor.

Damage Multiplier[]

All units, including buildings, have an inherent base armor value and attack class. Any physical damage dealt to a unit is multiplied by the damage multiplier, resulting in either damage reduction or increase depending on the target's armor value.

Damage Multiplier is also used to calculate a unit's Effective HP (EHP). The lower the damage multiplier, the higher the Effective HP of a unit, vice versa.

Armor Formula Base b Armor Formula Factor f
2 0.16

For any real-valued armor, the damage multiplier is defined as

With DMu being the Damage Multiplier and R the armor value.

The damage multiplier limits are 0 and 2, for infinitely positive and negative armor, respectively. Expand the table below for more detailed information on how much positive and negative armor affects damage multiplier.

The total amount of physical damage a unit can take due to the armor it has is known as Effective HP (or EHP). 16.66 armor adds 133.33% to EHP. This means a unit with 1000 health and 16.66 armor can take 2333.33 physical damage. The formula adds 6% EHP per point of armor regardless of the previous armor value.

EHP value has no diminished benefit as a player gaining 1 armor from 0 armor would increase EHP from 100% to 106%, while a player gaining 1 armor from 50 armor would increase EHP from 400% to 406%. This means each point of armor effects your HP and your survivability in the exact same way. On the other hand, the effectiveness of armor is much lower at negative values (refer to the attached graph). Total EHP trends downwards towards 50%, meaning a unit with 1000 health and infinitely low armor would still be able to take 500 physical damage. At this point, losing or gaining 1 armor has essentially no effect.

This definition of EHP assumes all damage taken is physical. EHP against magical damage (such as Laguna Blade icon Laguna Blade or Finger of Death icon Finger of Death) is modified by magic resistance.

Effective HP against physical damage is defined as

With CHP being the Current Health and DMu the Damage Multiplier.

Example 1
A Level 25 Sven minimap icon Sven has a total health of Expression error: Unexpected < operator. and Expression error: Unexpected < operator. points of armor without any items. What is his effective HP against physical damage?
Failed to parse (unknown function "\begin{align}"): {\displaystyle \begin{align} D_{Mu} &= 1 - \frac{0.16 \times <strong class="error">Expression error: Unexpected &lt; operator.</strong>}{2 + 0.16 \times \vert <strong class="error">Expression error: Unexpected &lt; operator.</strong> \vert} \\ \\ &= <strong class="error">Expression error: Unexpected &lt; operator.</strong> \end{align} }
Sven minimap icon Sven's damage multiplier is Expression error: Unexpected < operator. in this example.
Failed to parse (unknown function "\begin{align}"): {\displaystyle \begin{align} E_{HP} &= {<strong class="error">Expression error: Unexpected &lt; operator.</strong> \over <strong class="error">Expression error: Unexpected &lt; operator.</strong>} \\ \\ &= <strong class="error">Expression error: Unexpected &lt; operator.</strong> \end{align} }
Sven minimap icon Sven's effective HP against physical damage in this example is Expression error: Unexpected < operator..
Example 2
The same Level 25 Sven minimap icon Sven from the previous example (has a total health of Expression error: Unexpected < operator.) is affected by a Level 3 Corrosive Haze icon Corrosive Haze, and his armor is now Expression error: Unexpected < operator.. What is his effective HP against physical damage?
Failed to parse (unknown function "\begin{align}"): {\displaystyle \begin{align} D_{Mu} &= 1 - \frac{0.16 \times (<strong class="error">Expression error: Unexpected &lt; operator.</strong>)}{2 + 0.16 \times \vert <strong class="error">Expression error: Unexpected &lt; operator.</strong> \vert} \\ \\ &= <strong class="error">Expression error: Unexpected &lt; operator.</strong> \end{align} }
Sven minimap icon Sven's damage multiplier is Expression error: Unexpected < operator. in this example.
Failed to parse (unknown function "\begin{align}"): {\displaystyle \begin{align} E_{HP} &= {<strong class="error">Expression error: Unexpected &lt; operator.</strong> \over <strong class="error">Expression error: Unexpected &lt; operator.</strong>} \\ \\ &= <strong class="error">Expression error: Unexpected &lt; operator.</strong> \end{align} }
Sven minimap icon Sven's effective HP against physical damage in this example is Expression error: Unexpected < operator..
