Those observing the casting of this spell usually find it disturbing. This normally requires a fright check from anyone not used to gory sights. This is a natural consequence of the caster ripping their own head off. It isn't likely to phase someone that's seen it cast before, phobias not withstanding.

This spell, along with liberal amounts of ketchup or tomato sauce, is often used for practical jokes by sick-minded necromancers. Those that do this are normally looked down upon by their peers for being horribly tasteless.
