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 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 BlackbraidBlackbraidFur PlateArmour: (100-120)Movement Speed: -5.0%Requires Level 4, 10 Str+(40-60) to Armour+(5-15) to Strength+(5-15) to Intelligence+10% to all Elemental Resistances+(40-60) to Stun Threshold+(100-150)% of Armour also applies to Elemental DamageAn Ezomyte endures. or Doryani's PrototypeDoryani's PrototypeScale MailArmour: (187-250)Evasion: (168-224)Movement Speed: -4.0%Requires Level 37, 34 Str, 34 Dex(50-100)% increased Armour and Evasion+(60-100) to maximum Life+100% of Armour also applies to Lightning DamageEnemies in your Presence have Lightning Resistance equal to yoursLightning 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%.

Armour cannot reduce an instance of damage to below 1.

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).

Armour formulas

Relative damage reduction

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

D R ( A , D r a w ) = A A + 10 ∗ D r a w \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 Draw is the raw physical damage.

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

A ( D r a w , D R ) = D R ∗ 10 ∗ D r a w 1 − D R \color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}A(D_{raw},DR)={DR*10*D_{raw} \over 1-DR}

Armour Break

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.

Bear form

While Shapeshifted into a Bear, you gain +10 Armour per character level and +30% of your Armour also applies to elemental damage.

Evasion

Evasion is one of the three core defences that can be found on equipment. It is associated with dexterity and provides an entropy-based system of damage avoidance against most types of hits. Evasion chance is based on your Evasion Rating versus the enemy's Accuracy Rating.

Mechanics

Evading an attack prevents all damage from the attack and other hit-related effects. For projectiles, evasion prevents collision. Chance to evade/chance to hit is determined by a function of the defender's evasion rating against the attacker's accuracy rating. Chance to hit cannot go below 5%; likewise, chance to evade cannot exceed 95%.

The formula to calculate evasion chance is as follows: Uncapped Chance to Hit = Attacker's Accuracy ∗ 1.25 ∗ 100 ( Attacker's Accuracy + Defender's Evasion * 0.3 ) \color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}{\text{Uncapped Chance to Hit}}={{\text{Attacker's Accuracy}}*1.25*100 \over ({\text{Attacker's Accuracy}}+{\text{Defender's Evasion * 0.3}})}

Additionally, if the evasion check fails, leading to a hit, and that hit would deal a critical hit, the chance to evade is tested again independently. If this check is passed, the critical hit is downgraded to a non-critical hit.

Distance

Player attacks have an accuracy penalty that drops off with distance from the attacker between 2 metres (no penalty) and 9 metres (90% less accuracy rating); this primarily affects projectile skills.

Enemies do not have an accuracy penalty, but can be given one with Tactician's Stay Light, Use Cover or Vigilant ViewVigilant ViewEmerald RingRequires Level 26+(120-160) to Accuracy Rating+(100-150) to Accuracy Rating+(100-150) to Evasion Rating(10-20)% increased Rarity of Items found+(20-30) to DexterityEnemies have an Accuracy Penalty against you based on DistanceMaximum Chance to Evade is 50%Agony brings clarity to those of pure mind..

Entropy

Evasion is not a random system. Instead, it uses a deterministic "entropy" system that ensures a hit will occur after a certain number of evades:

• If it is the first time an entity is attacked, or if the time since the last attempted hit exceeds 100 server ticks (3.33 seconds), randomize the entropy value from 0-99.
• Calculate the attacker's chance to hit against the defender's chance to evade, and add this integer to the entropy value.
• If the resulting entropy value is lower than 100, the hit counts as evade. When the value reaches 100 or greater, the check counts as a hit, and subtract 100 from the entropy value.

The secondary critical hit downgrade test does not affect the entropy value.

As a result, if a player has a 1 in N chance to be hit, then the player will be hit exactly once for every N consecutive attacks. This eliminates all possibilities of lucky and/or unlucky streaks. It is still based on chance because of the entropy's value randomization in the first step. Note that if multiple mobs are attacking one character, all of the mobs' attacks share the same entropy value. The chance to evade shown in the character stats window is based on the average accuracy of a monster at the player's level.

Other mechanics

When defending against monster hits, there is no distinction between attacks and spells and will apply to any attack from enemies except boss attacks with a red flash.

When attacking monsters, their evasion provides avoidance against all attack hits, interacting with accuracy/chance to hit. Monsters cannot evade spell hits.
