When this spell is cast, the illusionist and all of his or her gear become insubstantial. The caster can be hit only by magic weap- ons of +1 or better, or by creatures otherwise able to affect those struck only by magic weapons. Undead of most sorts will ignore an individual in wraithform, believing him or her to be a wraith or spectre, though a lich or “special” undead may save versus spell at -4 to recognize the dweomer. The illusionist will be able to pass through small holes or narrow openings, even mere cracks, with all he or she wears or holds in his or her hands, as long as the spell persists. No form of attack is possible when in wraithform, except against creatures which exist on the Ethereal Plane, where all attacks (both ways) are normal. Dispel illusion and dispel magic are the only ways to force an illusionist in wraithform back to normal form. The spell caster can return to normal form at will, but this ends the spell effect. The material compo- nents for this spell are a bit of gauze and a wisp of smoke.
