Armor is a stat that reduces (or increases, if negative) physical damage a unit takes from spells 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 (with agility heroes gaining more than other heroes), talents, certain items, 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 0.16666666666667.

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.

The formula to calculate a hero's main armor is:

main armor = base armor + agility * 0.16666666666667

Bonus armor

Bonus armor is the armor value shown in green numbers with a plus on the left, right below the white armor number on a unit's statistics. Whenever an item or skill shows a +armor value, e.g. Blade Mail (+5 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. Some spells like Natural Order also only affect main armor.

Damage multiplier

All units, including buildings, have an inherent base armor value and armor type. 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.

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

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

The damage multiplier limits are 25/12 (roughly 2.08) and 0, for infinitely negative and positive armor, respectively.

Effective HP

Relationships between effective HP%, damage multiplier and armor

The extra damage a unit can take due to armor is known as its extra effective HP (or EHP) for physical damage. At 0 armor, 1 armor grants roughly 5.8% effective HP. This means a unit with 1000 health and 1 armor can take 1058 physical damage. At 30 armor, this figure scales upwards to 7.7%, meaning armor is more effective at higher values.

On the other hand, the effectiveness of armor is much lower at negative values (see graph). Total effective HP trends downwards towards 48%, meaning a unit with 1000 health and infinitely low armor would still be able to take 480 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	575.51	600	641.38	726.32	1000	1604.65	2268.29	3000	3810.81

This definition of effective HP assumes all damage taken is physical. In Dota 2, magical damage (such as Lina's or Lion's ultimate) is modified by magic resistance.

Calculating effective HP

effective HP = current HP ÷ damage multiplier

Example 1

A level 25 Sven has a total HP of 2293.6 and 11.3 points of armor. What is his effective HP vs physical damage?

EHP = 2293.6 ÷ ( 1 - (11.3 × 0.052) ÷ (0.9 + 11.3 × 0.048) ) = 2293.6 ÷ 0.592623 = 3870.25

Sven can tank 3870.25 physical damage.

Example 2

The same Sven from previous example is hit by a maxed Corrosive Haze. His armor is now . What is his effective HP vs physical damage?

EHP = 2293.6 ÷ ( 1 - ( × 0.052) ÷ (0.9 + × 0.048) ) = 2293.6 ÷ =

Sven can tank physical damage.

Armor types

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.

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 * 0.7719298245614 * 0.5) = 38.59649122807 damage. The same attack would deal 77.19298245614 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 armor type reduces against each attack damage type and which unit uses which armor type (units which take a set amount of damage per attack are excluded).

Armor Type	Used by	Attack Damage Type
		Hero	Basic	Pierce	Siege
Hero		100%	75%	50%	85%
Basic		100%	100%	150%	100%
Structure		50%	70%	35%	250%

Trivia

Negative armor damage multiplier for DotA and Dota 2

This graph shows how much more additional damage a target takes when armor debuffs are applied, using the 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% ( Visage) or 65% ( Meepo). Nowdays in Dota 2 magic resistance works independently from armor.
• The Basic armor type was referred to as Medium armor in DotA.
• The deprecated Light damage type used to be called Chaos damage in DotA.
• The deprecated Weak armor type used be called Light armor, Soft was referred to as Unarmored, and Strong was known as Heavy armor type.

Negative armor disparity

Amplified damage from negative armor is calculated differently in WC3 DotA than in Dota 2.

Negative armor in WC3 DotA has a cap of -20 armor (71% damage increase). Further reducing the armor does not change the damage increase. Also, the more aggressive damage amplify formula is used resulting in a max damage increase of 71%. The amplified damage is calculated from this formula:

Damage increase = 1 - 0.94^(-armor)
