Trebuchet

Choose one object weighing up to 200 pounds within range that isn’t being worn or carried. The object flies in an arc to strike a point of your choice up to 1000 feet away before falling to the ground, stopping early if it impacts against a solid surface. On impact, all creatures in a 5 foot radius must make a Dexterity saving throw. On a failed save, the target takes 8d10 bludgeoning damage and is knocked prone if it is huge or smaller. A creature that succeeds on its saving throw takes half as much damage and isn’t knocked prone. When the object strikes something, the object and what it strikes each take 8d10 bludgeoning damage, or twice as much if the target is a structure.

If damage from this spell kills a target, the target dies instantly.
