When this spell is cast, the spellcaster and all of his or her gear become insubstantial. The caster can be hit only by magic weapons. Undead of most sorts will ignore an individual in Wraithform, believing him or her to be a wraith or specter, though a lich or other high challenge undead may make a wisdom check at disadvantage to recognize the dweomer. The caster 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 magic is the only ways to force a caster in Wraithform back to normal form. The spell caster can return to normal form at will, but this ends the spell effect.

The material components for this spell are a bit of gauze and a wisp of smoke.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the duration increases by 2 rounds for every spell slot level above 3rd.
