Despite their intelligence, yrthaks do not speak.
An yrthak prefers to attack from the air, strafing the ground
with sonic attacks or snatching up and dropping prey (eventually
landing to devour the flattened mess).
Sonic Lance (Su): Every 2 rounds, an yrthak can focus sonic
energy in a ray up to 60 feet long. This is a ranged touch attack
that deals 6d6 points of damage to a single target.
Explosion (Su): The yrthak can fire its sonic lance at the
ground, a large rock, a stone wall, or the like to create an
explosion of shattered stone. This attack deals 2d6 points of
piercing damage to all within 10 feet of the effect's
center. This counts as a use of the sonic lance and thus is
usable only once every 2 rounds, and never on a round following a
sonic lance attack.
Snatch (Ex): An yrthak that hits a Medium-size or smaller
creature with a claw attack attempts to start a grapple as a free
action without provoking an attack of opportunity. If it gets a
hold, it can fly off with its prey and deal automatic claw
damage, though it prefers to drop victims from a height. It can
drop a snatched creature as a free action, which deals normal
falling damage if the yrthak is flying.
Blindsight (Ex): An yrthak can ascertain all foes within 120
feet. Beyond that range it is considered blinded. Yrthaks are
invulnerable to gaze attacks, visual effects of spells such as
illusions, and other attack forms that rely on sight.
An yrthak whose sense of hearing is impaired is effectively
blind, treating all targets as totally concealed.
Sonic Vulnerability (Ex): Yrthaks are affected by loud noises
and sonic spells (such as ghost sound or silence) and are more
susceptible to sound-based attacks, suffering a -2 racial penalty
to all saves.
Skills: Yrthaks receive a +4 racial bonus to Listen checks.
