Once per day as a full-round action, a peri can spin in an ever-faster, whirling dance, transforming itself into a spinning vortex of flame 10 to 40 feet high for up to 9 rounds. This ability functions as the whirlwind ability (DC 26 Reflex save), but any creature that comes in contact with the whirlwind or is caught inside it takes 2d6+6 points of fire damage and is subject to the peri's burn special attack. The save DC is Dexterity-based.
