Cruel Disappointment

(Book of Vile Darkness, p. 89)

Illusion (Phantasm) [Evil, Fear, Mind-Affecting]
Level: Sorcerer 3, Wizard 3, Spellthief 3,
Components: V, S,
Casting Time: 1 action
Range: Medium (100 ft. + 10 ft./level)
Target: One living creature
Duration: Instantaneous
Saving Throw: Will disbelief (if interacted with) and Will negates (see text)
Spell Resistance: Yes

The next time the subject of this spell attempts an action that requires a die roll to determine success, the action fails. However, the spell creates the phantasmal image in the subject's mind that the action succeeded. The subject behaves accordingly for 1 round. During the next round, the phantasm fades and the subject now realizes that he was fooled. If the subject fails a second Will save, he then takes a -4 morale penalty on attack rolls, saves, and checks for 1d6+1 rounds afterward.
