Focusing holy power like a ray of the sun, the character projects a blast of light from the character's open palm. The character must succeed at a ranged touch attack to strike the character's target. A creature struck by this ray of light takes 1d8 points of damage per two caster levels (maximum 5d8). Undead creatures take 1d6 points of damage per caster level (maximum 10d6), and undead creatures particularly vulnerable to sunlight, such as vampires, take 1d8 points of damage per caster level (maximum 10d8). Constructs and inanimate objects take only 1d6 points of damage per two caster levels (maximum 5d6).
