You shoot a black ray of necromantic energy from your outstretched hand, causing your foe to violently purge blood or other vital fluids through his skin.

You must succeed on a ranged touch attack with the ray to strike a target. If the attack succeeds, the subject is reduced to half of its current hit points (rounded down) and stunned for 1 round. On a successful Fortitude saving throw, the subject is not stunned.
