Dribble7631: Correct relative damage reduction for positive armor example (17%/50% = 34%)

== Armor ==

{{Iconbox|Armor|caption=no}}

Armor reduces the amount of damage you take by a percentage, increasing with the number of armor you have as seen below. Each point of armor increases the amount of damage it effectively takes to kill you by 6.66% per point.

[For a more complete list of changes per stat point, see ''[[Armor#Formulas & Values|Formulas & Values]]'' below.]

=== Effective HP ===
While the raw amount of % damage reduction goes down with each point of armor, the value of each % point goes up. For example: If you go from 0% reduction to 10%, that 10% reduction means you take 10% less damage. But if you go from 80% damage reduction to 90%, that +10% increase just ''halved'' the amount of damage you take.

So while the % Damage Reduction you gain from each armor point goes down, the effect on how much damage you can take before dying from each point remains the same..

Another example: If you have 100 Max HP and 0 armor, it takes 100 damage to kill you. But if you have 5 armor, you reduce the damage by 25%, so now it takes ''100/0.75=133'' damage to kill you. This amount of theoretical damage it takes to kill you is called 'Effective HP'.

Meaning for every 100 Max HP you have, each 5 points of armor allows you to take an additional 33 damage before dying. Said another way, 5 armor increases your Effective HP by 33%, and each point of armor increases your Effective HP by 6.66%.

=== Negative Armor ===
If you have negative armor, the damage you take is instead increased by the percentage. Where +15 armor would give 50% damage reduction, -15 armor means you takes 150% damage.

This means that negative armor, unlike positive armor, has strong diminishing returns. Going from 50% damage reduction to 67% (going from 15 to 30 armor) means you take 34% less damage than you were previously. But going from -15 to -30 armor means going from taking 150% to taking 167% damage, which means you just take a relative 11% more damage than before.

As a result, when you play {{CharacterIcon|Ghost}}, who starts with -100 armor (taking 187% damage), it doesn't make a notable difference if you gain +10 or -10 additional armor: it only changes the damage you take between 186% to 188%.

== Formulas & Values ==

The game uses different formulas for positive and negative values for armor.

<pre>% of damage received after being reduced by positive armor = 1 / ( 1 + ( ARMOR / 15 ) )

% of damage received after being increased by negative armor = (15 - 2 * ARMOR) / (15 - ARMOR)

Tooltip for Damage Reduction % = ROUND( ( 1 - ( DmgReceived% ) ) * 100 )</pre>

It can be clearly seen here that it takes 15 armor to doubles your HP. And that the Tooltip rounds the number to the nearest %

=== Rounding ===
The Tooltip for the Damage Reduction from Armor rounds to the nearest whole %. However, the actual damage reduction the game uses does not round, and instead uses the precise number.

Also note that [[Enemies#Enemies|enemy damage]] is rounded before armor is calculated. So if an enemy would deal 1.6 damage, that is rounded up to 2 damage, ''then'' armor is applied to the 2 damage. And then that number is rounded. So you need 6+ armor to reduce 2 damage down to 1, because you need to reduce it to under 1.5 damage for it to round down.

=== Tables ===

This table shows various damage reduction values with different Armor stats. The Dmg Reduction is the one shown by the tooltip. Below is the actual EHP granted by that amount of armor.
