With this spell, the caster is able to project images into the target's mind, making him see things which aren't there. The illusion is completely realistic, but it is seen only by the target and the caster, making the scene seem strange or even funny to onlookers. The spell requires concentration to maintain, which means that no other spells can be cast while Illusion is in effect.
