# Evasion Check

Evasion works similarly to critical hits but in reverse, determining whether an attack is completely dodged or not. It relies on the attacker’s **Evasion Ignore Rate** and the defender’s **Evasion Rate** to calculate the final chance of evading an attack.

#### Evasion Calculation:

Final Evasion Chance = Defender's Evasion Rate - Attacker's Evasion Ignore Rate

* If the result is positive, it represents the percentage chance that the defender successfully evades the attack.
* If the result is zero or negative, the defender will not evade, meaning the attack will hit.
* A single attack uses one evasion check, and if the evasion is successful, it avoids all damage and debuff checks (excluding displacement), triggering the "on evasion" keyword only once.

#### Example:

* **Defender's Evasion Rate** = 35% (due to high Agility and evasion-related skills)
* **Attacker's Evasion Ignore Rate** = 15% (from skills or equipment that reduce evasion)

The **Final Evasion Chance** would be: 

35% - 15% = 20% 

This means there is a 20% chance that the defender will successfully dodge the attack.

#### Evasion Mechanics:

* If the attack is evaded, the defender takes **no damage** from that attack.
* Some skills or talents may trigger additional effects when evasion is successful, like boosting defense or increasing speed.

#### Evasion and Crit Interaction:

Both **Evasion** and **Critical Hits** are calculated independently, so an attack could either be **evaded** or **critically hit**, but not both on the same attack. If the attack is evaded, the crit calculation becomes irrelevant since no damage is dealt.
