Shadow Shroud

When a wizard casts this spell, he uses an ordinary cloak as the focus for weaving a shadow cloak around himself. While he wears the cloak, the wizard is like an insubstantial shadow. He can't be seen for what he is as those around him mistake him for their own shadow or the shadow of a nearby object. The cloak doesn't render the wizard inaudible, however, and he must take care not to attract attention to himself through undue noise. If he enters an area of darkness, where no light penetrates, the spell ends. There must be some light for shadows to exist.

Aside from its usefulness in traveling about unseen, the shadow cloak allows the wizard to enter the Black (but not the Hollow) and interact with the denizens there. So long as he exits before the expiration of the spell, the wizard may freely return.

The wizard must determine what will keep the shadow denizens from attacking him. Should he be attacked by shadow giants, the wizard is allowed a saving throw vs. death magic to slip away from them unharmed and instantly be returned to Athas. Should he fail, he suffers the same consequences as anyone else attacked by such monsters.

The material components for this spell are a gray cloak (which is not expended in the casting) and a pinch of silver dust (approximately enough for 1 sp).
