Bahamut's Bravery

When flying, choose a location on the ground within your remaining movement speed. Draconic wings and claws manifest themselves onto your body as you dive with tremendous force, shattering the ground and manifesting lightning. Creatures within 10 feet of you must make a Dexterity Saving Throw. On a failed save, affected creatures take 6d8 lightning damage, or half as much on a successful one, and are frightened of you for 1 round. If you land directly on a creature, deal an extra 2d8 damage to the affected creature and yourself.

The caster must then make a Dexterity Saving Throw, and take 2d8 force damage on a failed save.
