Phantasmal Force IV
(Illusion/Phantasm)

Range:  5 feet per level
Components:  V, S, M
Duration:  1 round per level
Casting Time:  4
Area of Effect:  One creature
Saving Throw:  Special

When this spell is cast on a single individual of not greater than twice the Hit Dice or level of the wizard, the diabolic magic of the spell sweeps into the darkest corner of the victim's mind constructing from the idea an illusory form of the subject's greatest fear. This fear "strikes" with a 15 THAC0, is invulnerable to all attacks, and will kill the subject on a successful hit. Generally speaking, the only defense save for distracting the wizard is an attempt to disbelieve (make Intelligence check on 3d6). The material component for this spell is a bit of fleece.
