Tempest Crown

You crown yourself with a halo of stormwinds and flickering arcs of lightning. Until the spell ends, you gain the following benefits:

• You have a flying speed equal to your walking speed.
• When a creature hits you with a melee attack, it takes 2d8 lightning damage.
• As a bonus action on your turn, you can release a bolt of lightning toward a creature you can see within 30 feet. The target must make a Dexterity saving throw, taking 4d8 lightning damage on a failed save, or half as much on a success.
