Electrify

You electrify the ground in a 40ft diameter at a spot you can see within 120ft. It becomes difficult terrain, and any creature that enters the circle or starts its turn there makes a constitution saving throw. On a fail they take 5d6 electric damage and become stunned, and half damage on a success. Creatures that are stunned by Electrify automatically take full damage and add an additional 2d6 to the damage roll. They can make a constitution saving throw to break the stun at the end of their turn.
