Cannonball

You can point to a target you can see within 500ft and speak a command word. A dark pearlescent cannonball appears in the air in front of you and shoots towards your target. All creatures within 15ft of the target must make a Dexterity saving throw (DC15). On a failed save they take 5d10 of Force damage. On a successful save they take half the damage. This damage is doubled against structures.
