This spell transforms the air around the caster into the shape of any wholly physical Faerunian creature. It cannot create the shapes of creatures having a dual-planar existence or a fundamental connection to another plane of existence, such as most undead creatures. The monster form chosen must be of a creature that the caster has seen directly on some earlier occasion while it was alive and awake, but cannot be a unique being such as the tarrasque or a particular human ruler. The form must also be large enough to encompass the caster.
The caster controls this monstrous illusion from within and can use all the normal powers and abilities of the creature except—if applicable—flying. The illusory monster's attacks do only half the damage the real monster would, but the illusion also cloaks and shields the caster, who suffers only half the normal damage from attacks made on him or her while within the monstrous illusion. This spell can be ended at any time at will.
