Any place I can find a Lamia other than Hein's Castle?

[Misdreamer]

I've been going through the bestiary and filling out entries, and this is the only one I've got left. I've read online that some of the monsters that were previously locked to a single missable location, like Sahuagin, were added to some more accessible areas, and I was wondering if Lamia was one of those.
Or, barring that, if the bestiary achievement counts if you have the entries in separate saves, so that I don't have to literally redo everything.

Yes. Other achievements have to be done in a single save, but the bestiary is tracked separately.

Castle Hein is the only place to find one.

However, as was said, you don't need to unlock all the enemies on a single save. You'll get the achievement if you start a new game. If you're familiar with the game now, you can get back to Castle Hein in less than 2 hours if you want to play again.
