Arcane Ballista

You create a mass of pure arcane energy, and launch it with extreme force. Make a ranged spell attack against a creature or object in range you can see. On a hit, they take 8d8 force damage, and are knocked prone. Additionally, objects that are hit are treated as if as all dice rolled the maximum possible. A creature killed by this damage receives a large hole punched through their body where it hit.
Range: 300ft
On upcast: For every level above 5th, this spell deals 2d8 more force damage.
