As an action, you can let fly a feather of a phoenix and create a storm within a thirty foot sphere of you. When you cast this spell choose between cold, fire, lightning, or poison damage, this dictates how the storm looks and what damage it deals. All creatures within the storm at the time of casting must make a dexterity saving throw or take 8d8 damage of the chosen element. Additionally, when a creature ends its turn in this storm, it takes 8d8 damage of the chosen element and is moved 10 feet towards the center of the storm.
