DESCRIPTION

The next arrow you shoot emits a tremendously loud noise when it hits a solid surface, including a creature. You may choose whether the noise is, for example, a hideous shriek, a thunderclap, an animal or demonic roar, or any other wordless clamor.

All creatures within 30 ft. must succeed on a Fortitude save or be stunned for 1 round. Creatures with fewer than 6 Hit Dice that are within 10 ft. of the arrow's impact must make a Fortitude save or be knocked unconscious for 1 round. Deaf creatures are immune to the arrow's effects. In addition, magical effects that negate noise, such as silence, can cancel this spell's effect.

You must shoot the enchanted arrow within 1 round of casting thunder arrow or the spell dissipates.
