Spook

Illusion (Phantasm) [Mind Affecting]
Level: Illusionist 1, Sor/Wiz 2
Components: V, S
Casting Time: 1 action
Range: Close (25 ft + 5 ft/2 levels)
Target: One Living Creature
Duration: Special
Saving Throw: Will Negates
Spell Resistance: Yes

This spell enables the illusionist to play upon natural fears to cause the target creature to perceive the spellcaster as someone or something inimical.  Without knowing what this is, the caster merely advances threateningly upon the creature.  If the creature fails its Will save, it turns and flees at maximum speed as far from the wizard as possible, though items carried are not dropped.

Although the caster does not need to pursue the target creature, a phantasm from its own mind does.  Each round after the initial casting the target creature receives another save until it successfully saves and the spell is broken.  The spell functions only against critters with intelligences of 2 or more, and undead are not affected at all.
