A faint whirring sound and the stench of death precedes a great shape scudding through the air. The creature has a humanoid form with the skull of a long-toothed bull. Its upper arms are great wings, and its lower legs end in cruel, clawed talons. No skin or fur can be seen beneath the dingy gray funerary wrappings that cover the entire creature like a mummy.
Skirrs are predators that hunt the edges of necropolises, great expanses of deadly swamps, deserts, or other places where victims might be found alone, hurt, and pressed by dangers from directions other than the sky. That’s when skirrs swoop in to attack.
Skirrs measure, wingtip-to-wingtip, 50 feet or more, and weigh about 20,000 pounds.
Skirrs know no languages.
Skirrs are predators that scavenge the bodies of those killed by sudden stops. Their favored tactic is to swoop down, grab a victim, ascend to a height of at least 200 feet, and then drop the victim in a deadly fall.
Diet Dependent: A skirr is diet dependent (see Undead Metabolism) upon flesh, which it devours from the dead bodies of its victims.
Improved Grab (Ex): To use this ability, a skirr must hit a Large or smaller opponent with a bite attack. It can then attempt to start a grapple as a free action without provoking attacks of opportunity. If it wins the grapple check, it establishes a hold and usually flies upward as quickly as possible, intent on dropping its victim from a great height.
