You focus your light into a flash of power, burning your enemies.
Prerequisites
Planar Bloodline (Celestial), Celestial Glow, bloodline level 1st.
Benefit
While you have the Celestial Glow feat active, you can use a standard action to end that effect, concentrating the light into a beam of purifying energy. You can make a ranged touch attack which deals 1d6 sacred damage per effective spell level of the Celestial Glow ability, or double this amount of damage against undead and evil outsiders. This attack has a maximum range of 60 feet.
Alternatively, you can reduce the damage by half to affect all enemies in a 15 foot burst centered on yourself.
