Onkushi

Protective Aura (Su) Any creature within 20 feet of an onkushu, including the onkushu, gains a +2 divine bonus to its AC against attacks made by evil creatures and a +4 divine bonus to saving throws against effects created by evil creatures. While within this aura and affected by the onkushu’s life bubble spell, creatures are considered to have void adaptation and solar adaptation. If such creatures are willing or unconscious, the onkushu can carry them along with it while moving in any movement mode.

Fire Vortex (Ex) Three times per day as a standard action that provokes attacks of opportunity, an onkushu can buffet its wings to create a fiery vortex 10 feet tall and 10 feet wide that travels in a straight line for 30 feet. Any creature in that area is knocked prone, taking 10d6 fire and slashing damage (Reflex DC 21 for half damage and to avoid being knocked prone). If the vortex travels along the ground, the area it passes through is difficult terrain for 15 rounds.

Natives of the Plane of Fire, onkushus have long been the allies, mentors, and students of angels, learning virtuous practices while teaching the goodly hosts of the Outer Sphere the value of cleansing fire. Onkushus often take an interest in mortal affairs, using portals from the Plane of Fire that form within stars to come to the Material Plane. These outsiders are kindly by nature, but when angered or roused against evil, they can be implacable foes.

An onkushu is 15 feet tall and weighs 1,000 pounds while alive, yet it burns to a fine white ash when destroyed, leaving behind only a few pounds of material.
