Echo-Rotation

Echo-Rotation (minor) by Stone Gargoyle

The superbeing can distort sound waves, obscuring their direction.

Range: 400 foot radius, plus 100 feet per level

Duration: Constant, cannot be shut off. Uses no actions to activate or maintain.

Effects: Those with forms of superhuman hearing within the radius of the power suffer a penalty to the powers' skills to detect sound, a percentage equal to the superbeing's ME plus his IQ (so a superbeing with this power having an IQ of 16 and an ME of 18 would impose a penalty of 34%).
The superbeing takes only half damage from sonic and sound-based attacks. Those using sonic attacks in range of the superbeing suffer a penalty of to strike equal to the superbeing's ME bonus.
Note that this does not change the decibel level, pitch or sound quality of the noise, merely confuse the direction of the source of the sound waves.
