Spook

A spook spell enables the wizard to play upon natural fears to cause the target creature to perceive the spellcaster as someone or something inimical. Without actually knowing what this is, the wizard merely advances threateningly upon the creature. If successful, the creature turns and flees at maximum speed as far from the wizard as possible, though items carried are not dropped. Although the caster does not actually pursue the fleeing creature, a phantasm from its own mind does. Undead are not affected at all.

Note: This version of spook originally appeared in the 2nd Edition Player's Handbook for Advanced Dungeons & Dragons from TSR. Its use here is for the purposes of providing context for the campaign only.
