Cast

Area 100-foot burst
Range 300 feet
Saving Throw basic Reflex
You rip out a portion of an elemental plane and smash it into your plane, unleashing a chaotic maelstrom. When you Cast this Spell, choose an elemental plane. The collision deals 8d6 force damage and 8d8 damage of a type depending on the chosen plane to each creature in the area with a basic Reflex save. A creature that fails the saving throw is also pushed 25 feet away from the center of the burst (or 50 feet on a critical failure). Each creature whose movement is stopped by a firm surface, such as a well, takes bludgeoning damage equal to the remaining number of feet it would've moved. The area also becomes difficult terrain and hazardous terrain that lasts for a year and a day or until counteracted by a spell or effect such as Dispel Magic. Any creature that ends its turn in the hazardous terrain takes 15 untyped damage of a type depending on the chosen plane.
