Storm Pulse

A concussive surge of thunder erupts from your body, rippling outward in waves of pressure. Each creature - including allies - within 15 feet takes 1d6 damage on a failed DEX Quick save, or half damage on success. Those who fail are stunned for 1 round and then disoriented for 1d4 additional rounds, suffering -2 to attacks and -2 AC as they regain balance. The blast is accompanied by a deafening crack that echoes off stone and metal.

At 3rd level, damage increases to 3d6 damage. At 6th level, the radius expands to 30 feet and damage increases to 5d6 damage. At 9th level, damage increases to 8d6. Creatures that fail their save are pushed 10 feet outward and remain disoriented for 1d6 rounds.

Creatures (and allies) that fail the save are deafened for 2 rounds. Objects of glass, crystal, or fragile stone within 10 feet may shatter at the DN’s discretion. Cover: Creatures fully behind solid stone, metal, are protected completely form concussive damage, no save throw necessary.
