Intangible Cloak of Shadows

You merge with the border of the Plane of Shadow, and thus become insubstantial, invisible, and inaudible; yet your cast shadow remains and may easily betray you, and also sometimes scare the casual onlooker.

For you to be able to cast this spell, you must cast a shadow. Therefore, you cannot cast it in total darkness, nor in a place where light comes from everywhere, so you don’t project a shadow. Then, once you cast the spell you become insubstantial, invisible, and inaudible (plus without smell), however your cast shadow remains as if normal. This spell thus wields several effects:

• Inaudible: You cannot be heard by any means, and you cannot communicate (at least through speech) nor cast spells with a verbal component.
• Insubstantial: You cannot be touched nor hit, and you may pass through solid matter. However, your shadow is still substantial, even if only two-dimensional. As such, you may pass through a door, for example, only if your shadow may pass under it. If the door is totally sealed, you cannot pass through (under) it.
• Invisible: You cannot be seen normally, but your shadow can be spotted however. Yet, you gain a bonus to Hide skill rolls for your shadow being not detected. In areas with normal light you gain a +7 to your hide check, though you must remain in an area with at least some light.

Being insubstantial you cannot be touched nor attacked where you stands, even with magic. However, any attack directed against the shadow (that is: against a point on the ground, wall, etc., where your shadow is) affects you normally, and put an end to the spell. Similarly, if you try to attack someone with a melee weapon or spell, it puts an end to it. However, while you are in this shadow form, an attacker must use a magical weapon to be able to hit you (use your normal AC), and similarly you must have a magical weapon to be able to attack someone. (This is not Damage-resistance, but the conveying of a strike to or from the border of the Plane of Shadow.) Otherwise, while subject to this spell, you cannot enter areas of complete darkness, or areas of total light where shadow would be impossible. In ambiguous cases, determine if your body would cast shadows under normal circumstances. If yes, you may enter the area.

Material Component: a bit of black velvet of high quality (worth 1 sp).
