Spectral Farce

source=Dragon Magazine #229

The spectral farce spell is an illusion that makes images appear less believable, whether the images are real or illusory. If the images are real, the spell gives onlookers a reason to believe that they are fake. For example, spectral farce could make a charging red dragon's movements seem unrealistic, and also silence the sound of its claws raking against stone as it landed in a cavern. This could make enemies of the dragon believe that its an illusion and take actions to disbelieve its existence. If the images are illusory, the spectral farce spell can be highly effective at promoting disbelief. It grants a +4 saving throw when determining whether a viewer believes an illusion is real. If the viewer has already failed a saving throw, there is a chance that another saving throw will be allowed after spectral farce is cast. The chance is equal to 50% plus the level of the spellcaster. This spell can have all of the elements utilized in a spectral force spell, including sight, sound, smell and heat. Sometimes these are used primarily to mask an element, such as the case above where a dragon's claws were silenced.
