Blind is one of the possible afflictions to be caught in battle. When blinded, your attacks will miss more often and your Evasion and Luck will go to 0. When someone is blinded, a mosaic appears in front of their eyes.
Blind will remain even after the battle, so be sure to heal any party members before running in to more enemies. Blind will end after 30 seconds.
Curing and Preventing BlindEdit
Skill-wise, Prevent Blind is good if you're about to face an opponent you know is strong with blind. Stop Afflictions or Status Cure is better if you're uncertain or about to face an opponent that inflicts multiple afflictions.
The skill Bad Carrier will randomly inflict an ailment on your opponent, including blind.
