Full Manifestation

( Ghostwalk, p. 33)

[Ghost, Traveler]

You can manifest fully when you would otherwise be forced to be incorporeal.

Prerequisite

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.
