Armor

Armor

Armor reduces the amount of damage by x%, increasing with the number of armor you have as seen below:

• 1 = Take -6% less damage
• 2 = Take -12% less damage
• 3 = Take -17% less damage
• 4 = Take -21% less damage
• 5 = Take -25% less damage
• 10 = Take -40% less damage
• 15 = Take -50% less damage
• 30 = Take -67% less damage
• For a more complete list of changes per stat point, see Formulas & Values below.

While the amount of reduced x% damage per point

If you have negative armor, the damage you take is instead increased by the percentage. So if you have -15 armor, where 15 armor would give 50% damage reduction, -15 armor means you takes 150% damage.

Negative armor, unlike positive amounts of armor, has diminishing returns. Going from 50% damage reduction to 75% (thats going from 15 to 30 armor) for positive armor means you halve the amount of damage you take from 50% to only taking 25%. But for negative armor, this means going from taking 150% to taking 175% damage, which just means you take a relative 16% more damage than before. As a result, when you play Ghost, who starts with -100 armor, (taking 187% damage) it doesn't make a notable difference if you gain +10 or -10 additional armor. As it just changes the damage you take to between 186% to 188%

Formulas & Values

The formula used by the game for calculating Armor's damage reduction value is:

DmgReceived%  = 10 / ( 10 + ( ARMOR / 1.5 ) )
DmgReduction% = ROUND( ( 1 - ( DmgReceived% ) ) * 100 )

This table shows various damage reduction values with different Armor stats.

The "Increase" row shows how quickly the drop-off for damage reduction occurs (eg. going from 0 to 1 Armor gives -6% damage reduction, while going from 9 to 10 only gives -2% more reduction).

For every 1 :

ArmorStat	0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20
