Ancient Grudge

You summon the primal fury of nature in a 10-meter radius centered on a point within 40 meters. The ground trembles, plants attack violently, and natural energies surge. Each creature in the area must make an AGI Save against your INT Check. On a failed save, a target takes 4d12 + INT Bonus Nature damage and is knocked Prone. On a successful save, the target takes half damage and isn't knocked Prone. The terrain becomes difficult for 1 minute.
