Thunderstorm

You create a raging storm in a 25ft radius when in this storm all attack's have disadvantage and no attack's can leave the radius. Also when in the radius on their turn all creatures must make a strength save or have their movement halved until their next turn. Creatures you select in the radius must also roll a D4 and on a even number nothing happens but on a odd number they take 2D8 lightning damage and get moved out of the radius. You or a creature of your choice are in the eye of the storm, any creatures in the eye of the storm cannot take actions and your movement is 0 for the duration of the spell. You cannot be attacked and every round you heal for the damage dealt by the lighting.
