Pulsar Spin
Source
Horizons of the Vast: Serpents In The Cradle pg. 52
You can imitate the glory of a spinning pulsar. When you are fully photon-attuned, you can make a sudden spin as a standard action, emitting high-energy particles in a 120-foot line centered on you and extending 60 feet in either direction. Creatures in the affected squares other than you are exposed to low radiation. When you reach 6th level, creatures within your pulsar spin are exposed to medium radiation instead; at 12th level, they’re exposed to high radiation, and at 20th level, they’re exposed to extreme radiation.
In addition, when you use this power, any creature within 10 feet of you must succeed at a Fortitude save or be rendered off-target and flat-footed for 1 round by the tumultuous magnetic waves.
