This spell creates the visual illusion of an object, creature, or force, as visualized by you which activates when a specific condition occurs. The figment includes visual, auditory, olfactory, and thermal elements, including intelligible speech. You can move the image within the limits of the size of the effect.

You set the triggering condition (which may be a special word) when casting the spell. The event that triggers the illusion can be as general or as specific and detailed as desired but must be based on an audible, tactile, olfactory, or visual trigger. The trigger cannot be based on some quality not normally obvious to the senses, such as alignment.

The event that triggers the illusion can be as general or as specific and detailed as desired but must be based on an audible, tactile, olfactory, or visual trigger. Triggers react to what appears to be the case. Disguises and illusions can fool them. Normal darkness does not defeat a visual trigger, but magical darkness or invisibility does. Silent movement or magical silence defeats audible triggers. Audible triggers can be keyed to general types of noises or to a specific noise or spoken word. Actions can serve as triggers if they are visible or audible. A programmed image cannot distinguish alignment, level, Hit Dice, or class except by external garb.
