Comet

Fire a great magical comet at a creature that you can see within range. Make a ranged spell attack roll against the creature dealing 12d6 force damage on hit. Any creature in a straight line between the caster and target must make a dexterity saving throw against the spellcaster's spell save DC, taking half damage on a failed save or no damage on a success.

Additionally, if you do not use any movement on your turn, you can choose to charge the attack as a bonus action. When cast in this way the damage increases to 14d6 and your movement becomes 0 until the start of your next turn.
