Spectral Eyes

This spell establishes a visual link between the caster and a skeleton or zombie within the spell's range. The spell lets the caster see what the undead creature sees as if looking through the creature's eyes. The spell also allows the wizard to order the undead creature (each command up to four words long). If the creature moves beyond the spell's range, then the spell ends immediately. If the caster has infravision, he sees what the creature sees with infravision as well.

The material component of this spell is a carefully preserved eye.
