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 via leveling up, certain items, talents and some abilities. Armor of any unit can also be temporarily increased or reduced with some abilities.

Each point of agility increases a hero's armor by 0.167 or $\tfrac{1}{6}$ .

Total armor can be defined as
- Main Armor
  - × % Armor Negation Multiplier
- ± Flat Bonus Armor Values

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, which is gained by leveling up, acquiring certain items, or with the help of certain abilities.

³ Only affects

agility and

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

Drow Ranger - Marksmanship

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.
Elder Titan - Natural Order

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.

Example

How much main armor

Terrorblade with a

Blade of Alacrity at Level 8 has?

Base Armor: 5

Base

Agility and agility gain: 22 and 4 per level

Blade of Alacrity bonus agility: 10

{\displaystyle \begin{align} \text{Main Armor} &= 5 + \overbrace{\frac{ 10 + 22 + 4 \times 7}{6} }^\text{Agility} \\ &= 15 \end{align} }

Terrorblade has a total of 15 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 +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 with a

Blade of Alacrity and

Blade Mail at Level 8 have?

Base Armor: 5

Base

Agility and gain: 22 + 4

Blade of Alacrity bonus agility: 10

Blade Mail bonus armor: 7

{\displaystyle \begin{align} \text{Armor} &= \underbrace{ 5 + \overbrace{\frac{ 10 + 22 + 4 \times 7}{6} }^\text{Agility} }_\text{Main Armor} + 7 \\ &= 15 + 7 \\ &= 22 \end{align} }

Terrorblade has 22 total armor in this example.

Example 2

Terrorblade from the previous example is now affected by Level 3

Natural Order. How much total armor does he have now?

Level 3

Natural Order Armor Negation: 80%

{\displaystyle \begin{align} \text{Armor} &= \underbrace{ \left( 5 + \overbrace{\frac{ 10 + 22 + 4 \times 7}{6} }^\text{Agility} \right) \times \overbrace{ (1 - 0.8) }^\text{Main Armor Negation} }_\text{Main Armor} + 7 \\ &= \underbrace{ 15 \times (0.2) }_\text{Main Armor} + 7 \\ &= 10 \end{align} }

Terrorblade has 10 total armor in this example.

Modifying Armor

A lot of abilities and items have abilities that grant or reduce armor.

These changes only affect bonus armor. Reductions can nevertheless bring total armor into negative values if main armor is sufficiently small.

Causes the hero's attacks to place a debuff on the target that reduces the target's armor.

Successive attacks do not stack the debuff, but refresh the duration instead.

The attacks first apply the debuff, then their own damage.

Works against wards, buildings, and allied units.

Fully stacks with any other items or other sources of Armor Corruption.

The following armor reduction values exist:

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 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

Armor Based Ability Effects

Axe - Battle Hunger

Armor as Damage per Second: 100% ( 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`
1	0.06

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

{\displaystyle \begin{align} D_{Mu} &= 1 - \displaystyle\frac{ f \times R }{ b + f \times \vert R \vert} \quad \& \quad 0 \leq D_{Mu} \leq 2 \\ \\ &= 1 - \displaystyle\frac{ 0.06 \times R }{ 1 + 0.06 \times \vert R \vert} \end{align} }

With D_Mu 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.

Effective HP

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 100% to EHP. This means a unit with 1000 health and 16.66 armor can take 2000 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.

Armor	-40	-30	-20	-10	0	10	20	30	40
Effective HP	586.21	608.7	647.06	727.27	1000	1600	2200	2800	3400

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

Effective HP against physical damage is defined as

{\displaystyle E_{HP} = \displaystyle\frac{ C_{HP} }{ D_{Mu} } }

With C_HP being the Current Health and D_Mu the Damage Multiplier.

Example 1

A Level 25

Sven has a total health of 2293.6 and 11.3 points of armor without any items. What is his effective HP against physical damage?

{\begin{aligned}D_{Mu}&=1-{\frac {0.06\times 11.3}{1+0.06\times \vert 11.3\vert }}\\\\&=0.595948\end{aligned}}

Sven's damage multiplier is 0.595948 in this example.

{\begin{aligned}E_{HP}&={2293.6 \over 0.595948}\\\\&=3848.66\end{aligned}}

Sven's effective HP against physical damage in this example is 3848.66.

Example 2

The same Level 25

Sven from the previous example (has a total health of 2293.6) is affected by a Level 3

Corrosive Haze, and his armor is now -8.7. What is his effective HP against physical damage?

{\begin{aligned}D_{Mu}&=1-{\frac {0.06\times (-8.7)}{1+0.06\times \vert -8.7\vert }}\\\\&=1.34297\end{aligned}}

Sven's damage multiplier is 1.34297 in this example.

{\begin{aligned}E_{HP}&={2293.6 \over 1.34297}\\\\&=1707.86\end{aligned}}

Sven's effective HP against physical damage in this example is 1707.86.

On the other hand, the effectiveness of armor is much lower at negative values (refer to graph).

-There are several different types of armor, which determine how much damage a unit takes against certain [[attack damage types]]. Each of the 3 different armor types either reduces, increases or does not affect the damage from each of the damage types, on top of armor values manipulating them.
-Attack damage dealt against armor type is defined as

-: The armor type multiplier is 0.5 because the attack type "hero" deals 50% less damage against the armor type "structure".

-== Trivia ==
-[[File:Dota 2 armor disparity plain.svg|thumbnail|Negative armor damage multiplier for DotA and Dota 2]]
-[[File:Dota 2 bonus dmg.png|thumbnail|This graph shows how much more additional damage a target takes when armor debuffs are applied, using the [[Defense of the Ancients|WC3 DotA]] armor formula.]]
-* In DotA the base [[magic resistance]] was bound to the assigned armor. In case of ''Hero Armor'' only 75% of the magic damage was applied. Some heroes possessed hidden passive skills to alter their base magic susceptibility albeit ''Hero Armor'' to 90% ({{H|Visage}}) or 65% ({{H|Meepo}}). Nowadays, in Dota 2 magic resistance works independently from armor.
-* In [[6.86]] Armor types were renamed and some other types were removed.
-** The following armor types were renamed: Unarmored ➜ Soft, Light ➜ Weak, Medium ➜ Basic, Heavy ➜ Strong and Fortified ➜ Structure.
-** Weak and Basic armor types were removed. Units who previously uses the Weak and Basic armor type now use the Soft and Strong armor type respectively.
-=== Negative armor disparity ===
-Amplified damage from negative armor is calculated differently in [[Defense of the Ancients|WC3 DotA]] than in Dota 2.<ref>Dota2 Development Forum bug report: [http://dev.dota2.com/showthread.php?t=46896 <nowiki>[Confirmed] Negative armor has a different effect in DotA2 in comparison to Dota1</nowiki>]</ref>
-Negative armor in WC3 DotA has a cap of -20 armor (71% damage increase). Further reducing the armor does not change the damage increase.<ref>PlayDotA Mechanics: [https://web.archive.org/web/20161004063132/http://www.playdota.com/mechanics/damagearmor Damage and Armor - DotA Mechanics]</ref> Also, the more aggressive damage amplify formula is used resulting in a max damage increase of 71%.
-The amplified damage is defined as
