A black ray fires from your outstretched hand, piercing and passing thru nearby undead.

You must succeed on a ranged touch attack with the ray to strike a target. This spell functions just like disrupt undead, except that this ray deals 1d8 points of damage per caster level to any undead, to a maximum of 10d8.
