Blindness

Blindness was a Ta-Ree spell capable of being wielded by Ascendants on the planet Kathol. Ascendants using this spell could eliminate a target's sense of sight, leaving them able to see nothing more than a gray blur. Proficient and skilled wielders could use the spell to blind multiple targets.
