Destructive Harmonics (Su): A destrachian can blast sonic energy in a cone up to 80 feet long. It can tune the harmonics of this destructive power to affect different types of targets.

Reverberating Harmonics (Su): The destrachian can use a wall, a ceiling, or even a floor to reflect any of the sonic attacks listed above (except those that would damage the reflecting surface). This attack affects all within 30 feet of the destrachian, which is immune to the effects of its own ability.

Blindsight (Ex): A destrachian can use hearing to ascertain all foes within 100 feet as a sighted creature would.

Protection from Sonics (Ex): While they can be affected by loud noises and sonic spells (such as ghost sound or silence), Destrehan's are less vulnerable to sound-based attacks (+4 circumstance bonus on all saves) because they can protect their ears. A destrachian whose sense of hearing is impaired is effectively blind, treating all targets as total concealed (see Concealment).

Skills: With perhaps the most sophisticated auditory organs in existence, the destrachian gains a +10 racial bonus to Listen checks.

A destrachian uses its claws only as a last resort or to finish off foes weakened by its sonic attacks. Being extremely intelligent, it often enters battle with surprise if possible. It first focuses on destroying metal armor and weapons and then changes to harmonics that disrupt flesh.
