The Drunken Lizard Pub

There are several chests with combination locks. Where does one get the info needed?

The Tourax wake me up even near Aridell!!! Can they ever be eliminated?

It has been possible to eliminate all of a type of adversary, but I can't get rid of the Tourax. I am, frankly, getting tired of killing them, and I can't seem to get past them. Advice? Suggestions? Or do I somehow have a flawed game?

Thanks.
