Shockwave

Level: 1
Duration: 1 round
Saving Throw: None
By speaking this utterance, you order the air to pulse violently, knocking creatures in the area to the ground.
You speak words of power that cause the air to convulse outward in a pulse of violent energy. A violent shock wave travels through the air, and creatures in the area will be knocked prone and take 1d4 points of nonlethal damage. Creatures that are exceptionally stable—such as those with the stability racial trait or with four or more legs—gain their usual stability bonus (usually +4) on this Truespeak check.
