Almost too big to be believed, chaos rocs are immense birds of prey known for carrying off large animals (such as cattle, horses, or even elephants). These enormous birds lair in huge nests made from whole trees. They prefer to dwell high in the mountains, far from other large creatures such as rocs, dragons, and even other chaos rocs. This tactic ensures that the food supply in any one area is not compromised too severely. Each chaos roc usually hunts within a radius of about 10 miles around its own nest.
A chaos roc resembles a large eagle covered from head to tail with brilliant, shimmering plumage in rainbow hues. The creature measures 90 feet long from beak to tail, and its wingspan can be as wide as 240 feet.
Chaos rocs prefer to attack on the wing, using their prismatic spray ability to blind prey before attempting to snatch it up. Any additional damage done by the spray effect simply makes the snatch attempt easier.
Prismatic Spray (Su): A chaos roc can emit a spray of colored light from its eyes at will. The effect is like that of the spell (caster level 20th; save DC 29), except that the range is 105 feet, and only the colors red, orange, yellow, green, blue, and indigo are present (roll 1d6 instead of 1d8 on the table given for prismatic spray).
Swallow Whole (Ex): A chaos roc can swallow a snatched opponent that is Huge or smaller by making a successful grapple check. Once inside the roc, the opponent takes 2d8+12 points of bludgeoning damage and 1d8 points of acid damage per round from the bird’s gizzard. See Swallow Whole for escape methods and other information. The chaos roc’s gizzard has an AC of 20 and 25 hp and can hold 2 Huge, 8 Large, 32 Medium-size, or 128 Small or smaller creatures.
Feats: A creature that is flung by a chaos roc after being snatched travels 100 feet and takes 10d6 points of damage. If the chaos roc is flying, the creature takes this damage or the appropriate falling damage, whichever is greater.
