Full Manifestation
(Ghostwalk, page 33, DnD 3.0)
[Ghost, Traveler]
You can manifest fully when you would otherwise be forced to be incorporeal.
Benefit
When incorporeal, as a standard action you can make a Will saving throw (DC 15) to manifest fully for 1 round.
Normal
A ghost without this feat cannot manifest fully outside the Manifest Ward without magical aid.
