Flaws

Illusions are seldom perfect, and wary subjects will always be alerted to an image's illusionary nature by its imperfections. For instance, if a wizard uses a spell such as phantasmal force to create an illusionary creature, the creature might lack one or more obvious sensory elements, such as sound, aroma, or body temperature, which can be a dead giveaway that the creature is only an illusion. In extreme cases, the subject's saving throw can be modified by as much as +4. If the wizard is using a better spell, such as improved phantasmal force, any sensory elements lacking in the illusion will not be as obvious, and the subject's saving throw rarely will be modified by more than +2.

Examples:

· An illusion of a bee. Saving throw modifier: +1 (phantasmal force), 0 (improved phantasmal force) . The illusionary bee won't buzz in a lower-level illusion, but it will in the higher-level spell.

· An illusion of a hissing fire lizard covered with filth. Saving throw modifier: +4 (phantasmal force), +1 (improved phantasmal force). The lower-level illusion won't be able to duplicate the lizard's hiss, body heat, or the smell of the filth. The higher-level spell will do a better job, but the modifier assumes that at least one of these elements is imperfect or missing.
