Tempest Steed

You summon a horselike creature within range. The Creature is a horse made of Storm Clouds and each time the horse neighs a loud Thunder sound is heard. The horse can't run forever so it will need to take breaks.

For the duration, you or a creature you choose can ride the steed. The creature uses the statistics for a riding horse, except it has a speed of 100 feet and can travel 10 miles in an hour, or 13 miles at a fast pace. When the spell ends, the steed gradually fades, giving the rider 1 minute to dismount. The spell ends if you use an action to dismiss it or if the steed takes any damage.
