A roc attacks from the air, swooping earthward to snatch prey in its powerful talons and carry it off for itself and its young to devour. A solitary roc is typically hunting and will attack any Medium-size or larger creature that appears edible. A mated pair of rocs attack in concert, fighting to the death to defend their nests or hatchlings.

Snatch (Ex): A roc that hits a creature of at least Small size, but no larger than Huge, with a claw attack attempts to start a grapple as a free action without provoking an attack of opportunity. If the roc achieves a hold, it can fly off with its prey and automatically makes a bite attack each round in lieu of a claw attack. It can drop a snatched creature as a free action or use a standard action to fling it aside.

A flung creature travels 90 feet and takes 9d6 points of damage. If the roc flings it while flying, the creature suffers this amount of damage or falling damage, whichever is greater.

Skills: Rocs receive a +4 racial bonus to Spot checks during daylight hours.
