So the spell says:
"Each creature in the beam is blinded and takes 4d6 points of damage. Any creatures to which sunlight is harmful or unnatural take double damage. A successful Reflex save negates the blindness and reduces the damage by half.
An undead creature caught within the beam takes 1d6 points of damage per caster level (maximum 20d6), or half damage if a Reflex save is successful. In addition, the beam results in the destruction of any undead creature specifically harmed by bright light if it fails its save."
The question is, can an undead be blinded by this or not?
It's not clear if the second part is saying "if the subject is udead don't consider the above and do this" or "if he's an undead to the first part and ALSO the second one"
Thanks in advance for any help
