Flawless Hearing An aolaz has an incredible sense of hearing. It can hear any sound made within 1,000 feet as though it were only 5 feet away from the source of the sound, and any sound within 1 mile as though it were only 30 feet away from the source of the sound. An aolaz's hearing is a precise sense.

Roll [>] The aolaz tucks its head down and rolls up into an armored sphere. While Rolling, an aolaz has AC 44, Fort +37, Ref +29, Will +33, and Speed 100 feet, but it can't use its trunk Strikes or its Ultrasonic Blast. It can make foot Strikes while rolling, but only as part of a Trample. The aolaz can use this action again to unroll and resume its standing form.

Ultrasonic Blast [>] (arcane, evocation, sonic) The aolaz releases a tremendous blast of sonic energy from its trunk in a 150-foot line, dealing 12d10 sonic damage. The frequency of this sound is such that it is completely imperceptible to humanoids, but the damage it wreaks is all too evident. Each creature in the area must attempt a DC 40 Fortitude save. The aolaz can't use Ultrasonic Blast again for 1d4 rounds.
