Raven Swarm

Distraction: A creature with this ability can nauseate the creatures that it damages. Any living creature that takes damage from a creature with this ability is nauseated for 1 round; a Fortitude save (DC 10 + 1/2 creature's HD + creature's Con modifier) negates the effect. Eye Rake: Any living creature damaged by a murder of crows must succeed at a DC 13 Reflex save or be blinded as the swarm scratches and tears at the victim's eyes. The blindness lasts for 1d4 days or until healed with remove blindness. The save DC is Constitution-based.
