Q 131

For a Haunting Presence, does the CR-based restriction apply only to the part of the Poltergeist ability it gets at 10 HD? Or does it also apply to the baseline part of the ability?

Q 132

Does a familiar have the same challenge rating as a normal creature of its type? Or is its challenge rating modified somehow when it becomes a familiar?

Q 133

Can I use the Stitched Flesh Familiar feat to gain an undead version of any basic familiar? Like, say, an octopus? Or does it literally have to be one of the ones listed in the Player's Handbook?
