You can turn your phantom body into a cloud of deadly spectral energy.

Prerequisites: [Coatl], 5 HD

Benefit: You can make a phantom breath attack as a standard action, filling a 30-foot cone with a cloud of black spectral smoke, faint human and Coatl faces visible in the rolling smog. Creatures in the area take 1d6 points of negative energy damage per point of charisma modifier you possess, and gain 1 negative level. A successful fortitude save (DC= 10 + ½ your hit die + your charisma modifier) reduces the damage by ½ and negates the negative level. You cannot use this ability while using your phantom body ability, and after using it, you cannot use the phantom body ability or this ability for one minute.
