Trebuchet

Choose one object weighing up to  200 pounds within range that isn’t being worn or carried. The object flies in a straight line up to 900 feet in a direction you choose before falling to the ground, stopping early if it impacts against a solid surface. If the object would strike a creature, that creature must make a Dexterity saving throw. On a failed save, the object strikes the target and stops moving. When the object strikes something, the object and what it strikes each take 5d12 bludgeoning damage.

 If a structure is targeted with this spell, the structure takes double damage
