Special Abilities
<p><b>Amplify Frequency (Ex)</b> Whenever a polyphonic gel would take sonic damage, it absorbs that energy instead. The stored vibrations amplify the creature’s sonic waves, increasing damage dealt by the ooze’s next pseudopod attack before the end of its next turn by 2d6.<br/> <b>Resonant Vibrations (Ex)</b> When the polyphonic plasm deals sonic damage to the creature it has engulfed, it deals an equal amount of sonic damage to the creature’s armor as well. This damage ignores half of the armor’s hardness, rounded up.</p>
