Driving Rain

Heavy drops of rain batter down, hitting like sling stones and impeding vision. Each creature in a 15-foot area within 120 feet takes (scaling+3)d8[bludgeoning|options:area-damage] damage with a reflex save against your class DC. Until the start of your next turn, all creatures are Concealed while in the area, and all creatures outside the area are concealed to creatures within it.

Level (+2) The damage increases by 1d8.
