Deafening Bellow (Su): Once per day, a quaraphon can let loose a cacophony of noise from its two mouths. Any creature within 60 feet of the quaraphon takes 2d6 points of sonic damage and must make a DC 20 Fortitude save or be deafened for 1d6 rounds. The save DC is Constitution-based.

A quaraphon is an unsubtle combatant that relies on its brute strength to discourage any serious resistance. It first lets loose a deafening bellow before charging in on its victim.

A quaraphon normally attacks using its Power Attack feat, taking a -3 penalty on its attack rolls and gaining a +3 bonus on damage rolls.
