Armour

Armour is a defence that provides damage reduction to incoming physical damage from spells and attacks. The % of damage reduced depends on the size of the incoming hit relative to the armour value and cannot exceed 90%. Armour is associated with strength. Hits with Hits Break # Armour can Break a given portion of armour, rendering that amount of armour ineffective.

Mechanics

Armour grants physical damage reduction, with the exact amount of damage reduction depending on the ratio of armour to the physical damage of the hit. If the armour value is significantly larger than the damage, most of the damage is prevented. If the armour value is similar to or less than the incoming damage, only a small percentage of that damage will be prevented. As a result, armour is more effective against many smaller hits rather than fewer larger hits, even if the total damage dealt would be identical.

Armour can reduce damage up to a fifth of its value; for example, a character with 1000 Armour can prevent a maximum of 200 physical damage from a single hit from armour alone.

Armour never mitigates damage over time, as armour only applies to hits. Bleed is an ailment that deals physical damage over time that is based on the physical damage dealt by a skill before mitigation; armour will reduce the hit damage but not the damage over time. However, both the hit damage and the damage over time can be mitigated with sources of #% additional Physical Damage Reduction. The maximum total physical damage reduction from all sources is 90%.

Normally Armour only applies to physical damage; however, it can be made to apply to other damage types through items or passive skills, such as Blackbraid or Doryani's Prototype. In such cases, the armour value applies independently to each damage type. The maximum elemental or chaos damage reduction is also 90%.

Armour formulas

Relative damage reduction

The following is the base formula that can be used to calculate the damage reduction gained from armour^[1]:

$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}DR(A,D_{raw})={A \over A+12*D_{raw}}$

where A is the defender's armour rating and D_raw is the raw physical damage.

Required armour rating

To calculate the armour rating required to mitigate a given amount of damage at a specific ratio, the following formula can be used:

$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}A(D_{raw},DR)={DR*12*D_{raw} \over 1-DR}$

Armour Break

Armour Break is a mechanic that allows players to reduce enemy armour by a specified amount. Armour break lasts for 12 seconds, after which the broken armour will be regained. If the target's armour value reaches 0, their armour will be Fully Broken for 12 seconds, after which they will regain all armour. Armour broken is triple against normal monsters and double against magic monsters.

Armour cannot be broken below 0 unless Lua error: Error: Table passive_skills not found.. is allocated. If so, Armour can be broken up to the inverse of its original value; for example, an enemy with 1000 armour can be broken up to -1000 armour. Negative armour grants a damage multiplier rather than a damage reduction at the same ratio.
