Description: When this spell is cast the caster creates a visual illusion which will affect all believing creatures which view the spell, even to the extent of suffering damage from phantasmal missiles or from falling into an illusionary pit full of sharp spikes. Note that audible illusion is not a component of the spell. The illusion lasts until struck by an opponent-unless the spell caster causes the illusion to react appropriately- or until the caster ceases concentration upon the spell (due to desire, moving, or successful attack which causes damage). Creatures which disbelieve the spell gain a saving throw versus the spell, and if they succeed, they see it for what it is and add +4 to associates’ saving throws if this knowledge can be communicated effectively. Creatures not observing the spell effect are immune until they view it. The spell can create the illusion of any object, or creature, or force, as long as it is within the boundaries of the spell’s area of effect. This area can move within the limits of the range.
