Razorwing

''With swift beats of its wings, this reptilian animal glides a few feet above the silt. Its wing-flaps run between fore and hind limbs and are lined with a hard bony ridge.''

Combat
A razorwing lies in wait under the silt until it sense its prey approaching, then flies from the silt on wings enhanced by telekinesis to attack. Razorwings make swooping wing attacks while airborne, but they attack with claws and beak when they land. Its wings inflexible, a razorwing can only make one wing attack each round.

Description
Razorwings hide under the silt and burst out of the sand to surprise creatures flying above. These vicious carnivores, when attacking in waves, have been able to bring down creatures much larger than themselves.

This small, slate gray-colored beast looks much like a small pterrax but has very sharp bone leading edges on its wings, which it uses as weapons in combat.

Razorwings can communicate with others of their kind, using their power of control sound to communicate, since they have no language.
