Aura of the Storm Lord

A bolt of lightning containing the essence of the storm lord crashes onto the caster, dealing 3D6 damage to every creature within 5ft of the caster of a failed dex saving throw.

For one minute after the bolt hits the caster he is imbued with the powers of the storm lord, you gain a hover speed and height of 15 ft (this movement does not count against movement used this turn and it cannot provoke attacks of opportunity) as well as any creature that makes a melee weapon attack against the caster does so at disadvantage and takes 2D6 lightning damage. The electricity flowing around the caster gives him a plus 2 to their AC and as well once a turn as an action is able to call down a hammer of thunder to crush your enemies, pick an area you can see, within 120ft, that is 15ft by 20ft each creature within it takes 5D8 thunder damage of a failed dex saving thrown, or half as much on a success, as well any creature that fails takes lightning damage equal to the spell slot level the spell was cast at.

Up casting this spell adds 1D8 to the hammer damage for each level above 6
