Considering that the snakes only have a few HD and are adapted to melding with the carpet, I'd be fine with reducing the damage to 2d6 or so (and reducing the Fort DC). As for spells, I'm not sure what to use, but that listing can provide some inspiration perhaps. What do you all think?
Cleon, did you see the bit in the proposed write-up about the destruction of the carpet? There's an additional Fort save for the snake to avoid being killed outright.Contrariwise, if the snake takes 5d6 damage upon expulsion then it could explain why destroying the carpet often destroys the snake, since that'll typically do more hit points damage then an average carpet snake has it'll usually emerge unconscious or dying.

The "Destroying the carpet completely expels the snake as above and kills it instantly unless it succeeds at a DC 15? Fortitude save" bit in freyar's post 148?
Afraid I didn't notice it buried in the middle of the paragraph.
Suppose that would work, but I'd prefer a higher DC so it's usually fatal (DC18? DC20?)
Are we going to write an SQ about being bonded to certain masters, or do we want to leave that as flavor? I kind of like making it "official" in the mechanics, but it's no big deal.
Sounds more like flavour. Could do a "Training a Carpet Snake" subentry if you like.
