Harpy Eagle

Female harpy eagles are much larger than males, weighing 1d8+22 pounds with a wingspan of about 6-7 feet. Males, by contrast, weigh 1d3+15 pounds, and have a -2 penalty to all attack and damage rolls (with a minimum of 0 damage on a successful attack). On a critical hit, victims who fail a DC 10 Reflex save are blinded in one eye ( -2 penalty to attack rolls and relevant checks). Those who fail by 5 or more are blinded in both eyes. After 1d6 turns the victim may attempt a DC 20 Fort save for each eye affected to regain sight; failure indicates permanent blindness.
