You must succeed on a ranged touch attack with the ray to strike a target. This spell functions like disrupt
undead (PH 223), except that this ray deals 1d8 points of damage per caster level to any undead, to a maximum
of 10d8. If the damage is sufficient to destroy the first target, then you can redirect the ray to another
undead target within 15 feet of the first target. If you make a successful ranged touch attack on the second
target, that target takes half of the damage rolled for the first target.
