Feat: Thunder Clap

You slam your hands together to unleash a deafening blast. Creatures in a @Template[cone|distance:15] cone take (max(3,floor(@actor.level/2)))d6 sonic damage, with a Basic Fortitude against your class DC. Creatures that critically fail their save are also Deafened for 1 minute. You can't use this ability again for [[/r 1d4 #Recharge Thunder Clap]]{1d4 rounds} as your hands recover from the thunderous vibrations.

At 8th level, and every 2 levels thereafter, the damage from Thunder Clap increases by 1d6.
