Power Word, Blind

When a power word, blind spell is cast, one or more creatures within the area of effect become sightless. The spellcaster selects one creature as the target center, and the effect spreads outward from the center, affecting creatures with the lowest hit point totals first; alternatively, the spell can be focused to affect only an individual creature. Creatures with a current hit point total over 100 hit points are not affected and do not count against the number of creatures affected. The spell affects up to 100 hit points of creatures, but the duration depends upon how many hit points are affected. If 25 or fewer hit points are affected. the blindness is permanent until cured. If 26 to 50 hit points are affected, the blinding lasts for 1d4 + 1 turns. if 51 to 100 hit points of creatures are affected, the spell duration is but 1d4+1 rounds. An individual creature cannot be partially affected; if all of its current hit points are affected, it is blinded, otherwise, it is not. Blindness can be removed by a cure blindness or dispel magic spell.
