You can channel divine energy into your body and mind to temporarily transform yourself into a half-celestial or half- fiend. This means you gain wings that allow you to fly at twice your land speed (good maneuverability), receive a +1 to natural armor, can cast daylight or darkness at will, and can smite evil or good once each day.
Prerequisite: Con 21, Knowledge (the planes) 30 ranks, ability to turn or rebuke creatures.
Benefit: Spend one of your turn/rebuke undead attempts to infuse your mind and body with potent energies pulled directly from the realm of your deity. You use a standard action to channel your energy, during which time you transform. For a number of rounds equal to your Charisma modifier minimum of 1 round), you gain either the half-celestial (if you channel positive energy) or the half-fiend (if you channel negative energy) template. You gain the native subtype while you're an outsider. The spell like abilities of the half-celestial or half-fiend are based on your Intelligence and Hit Dice. Daily use limits apply per day, not per use of this feat.
