Sunbeam

Description
You summon a globe of divine radiance to blind and burn those within the area of effect. Undead take 1d6 points of divine damage per caster level, to a maximum of 20d6. All other monster types take 3d6 points of divine damage, and are blinded for 3 rounds. A successful Reflex save halves the damage for undead and voids blindness for others.
