Deluge

You unleash a concentrated deluge of water with the force of a bomb. Target a 10ft x 10 ft area within range. Any creature hit must make a DEX saving throw. On a failed save, the creature takes 4D6 Cold Damage and is soaked for a minute. A soaked creature takes an additional 2D6 damage from magical sources dealing Cold or Lightning damage. While soaked, fire damage to the creature is reduced by 2D6. This effect ends if a creature uses its action to dry off or takes fire damage. On a successful save, it takes half as much damage and a creature can not be soaked more than once at a time.

At Higher levels: For each spell level above 2nd, this spell deals an additional 1D6 Cold Damage.
