You call upon the elder spirits of the forest and incite their wrath against your foes. A mighty branch of a size Huge or larger tree you can see within range slams down into a creature of your choice you can see within 15 feet of the target. Make a melee spell attack against the creature. On a hit, the target creature takes 5d12 bludgeoning damage, is knocked prone, and if the creature is smaller than the tree, is flung 20 feet in a direction of your choice.
