Firestorm

As a standard action, you can cause fire to erupt around you. You can create one 10-foot cube of fire per oracle level. These cubes can be arranged in any pattern you desire, but each cube must be adjacent to another and one must be adjacent to you. Any creature caught in these flames takes 1d6 points of fire damage per oracle level, with a Reflex save resulting in half damage. This fire lasts for a number of rounds equal to your Charisma modifier. You can use this ability once per day. You must be at least 11th level to select this revelation.
