A ghost which has manifested is incoporeal, so it can affect opponents with its touch attacks but not with physical attacks (such as ordinary ghost weapons). (But using a magic ghost weapon it can affect opponents 50% of the time.)
1) This would mean that a ghost threatens adjacent squares only if its using its touch attacks, but not if it's using an ordinary weapon, and half the time if it's using a magic weapon. Is that right?
2) Say the ghost can't get an threaten or get an attack of opportunity on an opponent. (Either it's used the attack this round already, or it's flailing away with a useless weapon.) What prevents the opponent from just running through the ghost's square?
3) Even if an attack of opportunity succeeds, can you just run through an incorporeal creature's square? Or does the attack stop you?
