Armour

This page is about the defensive stat. For equipment classified as armour, see Armour (equipment).

Estimated Armour Mitigation

Tooltip

Armour reduces the Physical Damage you take from both Attacks and Spells (but provides no benefit against other Damage Types).

Exact Damage Reduction depends on the Damage dealt, but cannot be higher than 90%.

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 BlackbraidBlackbraid

Armour also applies to Lightning damage taken from Hits
Enemies in your Presence have Lightning Resistance equal to yours
Lightning Resistance does not affect Lightning damage taken"This was the first step in some grand design,
lost to the ages, now ours to decipher."
- Dominus, High Templar. In such cases, the armour value applies independently to each damage type. The maximum elemental or chaos damage reduction is also 90%.

Rule of thumb

• To prevent one third of damage (33%), you need armour 5 times the damage (e.g. 500 armour for 100 damage)
• To prevent half of damage (50%), you need armour 10 times the damage (e.g. 1000 armour for 100 damage)
• To prevent two thirds of damage (66%), you need armour 20 times the damage (e.g. 2000 armour for 100 damage)
• To prevent three quarters of damage (75%), you need armour 30 times the damage (e.g. 3000 armour for 100 damage)
• To prevent 90% of damage, you need armour 90 times the damage (e.g. 9000 armour for 100 damage)

When the damage of a hit significantly exceeds Armour, it will never prevent more damage than the armour value divided by 10 (e.g. 1000 armour will never prevent more than 100 damage at its minimum percentage prevention).

Relative damage reduction

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

$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}DR(A,D_{raw})={A \over A+10*D_{raw}}$

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:

$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}A(D_{raw},DR)={DR*10*D_{raw} \over 1-DR}$

Armour Break is a debuff that reduced Armour by a specified amount. When a target's Armour is broken to 0, it has Fully Broken Armour, which interact with certain mechanics. Enemies (but not players) with Fully Broken Armour also take 20% increased physical damage from hits.
