Blind

Blindness is a condition affecting a character's ability to accurately land blows on opponents. While affected, that player's attacks have a 90% chance of missing and projectiles have a greater chance of straying from their intended target. A blind character can easily be spotted due to the black mist that appears in front of their face. Blindness is especially harmful to assassins, warriors, and rangers who have few ways of inflicting damage except through their weapons. Blindness is calculated when the projectile or attack would hit the target. Blindness applied to foes while their projectile is in flight can cause the projectile to miss.

Note
The green item Tanzit's Defender reduces blind duration on you by 20%.
