Ghosts (sometimes called Shades for good reason) are mere shadows of their former selves. They no longer have physical bodies and cannot enjoy the simple things in life that the living take for granted.
Ethereal Undead are immune to physical harm, can pass through solid objects and can fly through the air (or solid objects) at their normal movement rates. They cannot touch anything material and may not use physical objects they find. As Undead they do not require sustenance, do not breath (and are therefore immune to air based poisons) do not tire and never need to sleep.
Effects: Ethereal, Undeath, Duration (Permanent)
