How long does the effect from a monsters gaze attack last?

[Dark Arioch]

Perhaps there is something obvious that I am missing but so far I can't find anything specific.

Specifically, I am running a Bandersnatch in a current encounter and it has a confusion gaze. How long do the effects from this last? Is it just a single round thing since you have to save each round or is it a longer duration thing like the Spirit Naga's charm gaze? Actually, that brings up a similar question: How long does a spirit naga's charm gaze last? Obviously, a medusa's petrification gaze is permanent until cured. So are these other effects permanent also?

A Spirit Naga's gaze is "as charm person" so I would assume for the duration of the spell with a CL is equal to the creature's hit dice.

A Bandersnatch is simply the condition, so it might be for one round.

Yeah, kind of interesting that it leaves us guessing. You would think there would be something a little more definitive out there. Almost like the ability made it into the book in its concept stage and still needed the mechanics written.

As for the Spirit Naga's Charm ability the CL could be based off a couple of things. Such as the CL of it's other spell-like abilities or as you said, it's hit dice.

It depends on the creature. In these two cases they did not put the duration but they should have. They need to be FAQ'd so they can be fixed.
