Thunder Clap

You clap your hands together with unnatural force, creating a loud bang. This can be heard clearly 1000 ft. away in an open area, and ten times as far in a place where there is an echo.
Any creature within 10 ft. of you must make a Fortitude save against your WIS CL.
On a failure, they take 1 D8 + your Magicka in Thunder damage. On a Critical failure, they are Deafened for 1 D4 rounds.

This spell’s damage increases by 1 D8 for every 5 caster levels.
