Chaos Meteor

You conjure a meteor to land 60 feet from you in a 10 foot diameter, any creature in the area must succeed on a dexterity saving throw, or take 3d8 bludgeoning damage and 4d6 fire damage. On a success they take half damage. After the meteor lands it rolls in a straight line for 15 feet on your next turn, any creature in line takes 2d6 points of fire damage after which the meteor crumbles into dust.

The meteor also provides cover.
