This spell generates a spark that detonates with an incredibly loud boom followed by a devastating shockwave. This spell deals 1d4 points of sonic damage per level (maximum 8d4) to all creatures within the area. Unattended objects also take this damage. Furthermore, Large or smaller creatures within the area that fail their Reflex save are knocked back 5 ft. away from the direction of the explosion center and must make a Fortitude save or be deafened for 1 round. Although Huge or larger creatures that fail their save are not knocked back or made prone, they must still save vs. deafness.

You face the palm of your hand in the desired direction and determine the range (distance and height) at which the thunderclap is to burst. A tiny blue spark streaks from your hand and erupts into a thunderclap at that point. If the spark impacts a body or solid object before arriving at the set range, the spark detonates at that point. If you attempt to send the spark through a narrow passage, such as through an arrow slit, you must “hit” the opening with a ranged touch attack, or else the spark strikes the barrier and detonates prematurely.
