I think it would be a pretty cool idea for Bethesda to do in a patch or DLC. There would be the pros and cons (and these aren't like what they HAVE to be, just thoughts) just like with the other 2:
Pros:
When you turn ghostly, you float in mid air! (jus like vampire lord)
When in ghost from, you take 10-25% less damage because it goes through you.
When in ghost form, you can move faster because you use less stamina.
You can turn invisible during Nighttime. (can be once a day thing or unlimited use)
Cons:
Because you are considered undead, you will not gain bonuses when sleeping. (ghost or not)
One of the 3 main skills decrease skill upgrade by 10, 20, 30% ? Somewhere around there.
So basically, the ghost would be a pretty cool feature in the BLOOD-line. (ha) it's pretty much a choose-when-you-want-to philler of the phantom effect.
Give your pros and cons ideas so Bethesda can get a good look at them. Hope it sells!
