Evasion is the first layer of defence that increases a character's chance to evade incoming attacks. Evasion is opposed by the attacker's accuracy. Along with armour and energy shield, evasion is one of the three defence types that can implicitly appear on equipment.
All classes start with 53 base evasion rating and gain 3 additional evasion per level. The first level is included in this, so a level 1 character will have 56 base evasion. This gives a base of 353 evasion at level 100.
Dexterity also grants bonuses to evasion. Every 5 points of dexterity provide 1% increased Evasion Rating. Non-multiples of 5 will be rounded up to the nearest multiple of 5 (e.g. 142 dexterity will be rounded to 145).

Evading an attack prevents all damage and other harmful effects including status ailments and stun. Only melee and ranged attacks can be evaded; spells will automatically hit. The chance to evade an attack is based on the defenders evasion rating verses the attacker's accuracy.
Chance to evade can never be lower than 5%, nor higher than 95%. The exception to this is the modifier Cannot Evade enemy Attacks from for example the Unwavering Stance keystone or Ezomyte PeakEzomyte Peak

Cannot Evade Enemy AttacksCenturies of servitude, a day
of glory, an eternity of death.; this completely removes the character's chance to evade. As an opposite, hits with Hits can't be evaded modifier do not take target's chance to evade into account.
Evasion also gives an implicit chance to not receive critical strikes from attacks. Critical strikes from spells can't be evaded. If an incoming critical strike succeeds its hit roll, a second independent hit roll is performed to determine if the critical is evaded or not. If this roll succeeds, a critical strike is scored. If it fails, the attack still hits, but only for regular damage.
Evasion is not purely based on chance in the sense that each hit is independent. Instead, it uses a system of "entropy" to ensure that enemies won't get long strings of hits or misses by chance. To summarize, these are the calculation steps in each attack:
- If it is first time an entity is attacked or if the time between the last attack and this one is larger than 6 seconds, randomise the entropy from 0–99.
- Calculate chance to hit of the attacker using the above formula, and add this integer to the entropy counter.
- If this is 100 or greater, the check counts as a hit. Subtract 100 from the entropy counter. Otherwise it is a miss and the entropy counter doesn't change.
- A critical hit is evaded on a separate random roll and will not affect this entropy value.
This system is designed to evenly spread out hits and misses such that players always evade an average number of times according to their ‘chance’ to evade. It is still based on chance because of the entropy counter's randomization in the first step. Note that if multiple mobs are attacking one character, all of the mobs' attacks share the same entropy counter. Also note that the chance to evade calculation on the character page is based on the average accuracy of a monster at the player's level.
Interaction with Dodge
Chance to Dodge bonuses granted by sources like Acrobatics function similar to evasion, but are rolled separately and are pseudo-random rather than entropy-based. Phase Acrobatics grants a chance to dodge spells.
Assuming a character has a 40% chance to evade and a 20% chance to dodge, a character has a 52% chance to prevent receiving a hit.
Modifiers to chance to Hit and chance to Evade
Certain modifiers can be directly applied to the Chance to Hit and Chance to Evade stats, such as blind, and Arrow Dancing. The order in which these take effect are as follows; chance to hit is determined based on the attacker's accuracy and the defender's evasion, then modifiers to the attacker's chance to hit get applied, after which modifiers to the defender's chance to evade are applied to get the final chance to evade/hit.
A player is fighting three monsters, one (A) with a 70% chance to hit and two (B, C) with a 45% chance to hit.
- A attacks. The player's entropy is a random number between 0-99, in this case 37.
- A adds 70 to the counter, raising it to 100 or greater, and hits. 100 is subtracted and the counter is now 7.
- B attacks, adding 45. 52
- C attacks, adding 45. 97
- A attacks, adding 70. This hits and the counter becomes 67. It happens to be a critical strike, which means it has a 70% chance to do bonus damage. This roll is independent and doesn't affect entropy.
- The player runs away for >6 seconds, so a new entropy value will be rolled on the next attack.
- Chance to Hit = 500 / ( 500 + (5000/4)^0.8 ) = 62% Chance to Hit.
- Blind lowers the chance to hit to 31%, meaning the player has a 69% chance to evade.
- Shade Form's 20% more Chance to Evade causes the final chance to Evade to be 69 * 1.2 = 82%.
