Antipathy Spell
Antipathy Description: You cause an object or location to emanate magical vibrations that repel either a specific kind of intelligent creature or creatures of a particular alignment, as defined by you. The kind of creature to be affected must be named specifically. A creature subtype is not specific enough. Likewise, the specific alignment to be repelled must be named.
Creatures of the designated kind or alignment feel an overpowering urge to leave the area or to avoid the affected item.
