Abjuration
Range: Touch
Target: Defensive
Syntax: cast 'invis to undead' <target>
Undead cannot see, hear, or smell the warded creatures. Even extraordinary
or supernatural sensory capabilities cannot detect or locate warded creatures.
If a warded creature attempts to turn or command undead, or attacks any
creature, however, the spell ends.
* Note that this spell may be resisted by the more powerful undead creatures
