Good info, Clockin!
I would just like to stress the importance of agreeing to do the deed for Kresselack, if you select any of the other dialogue options the priestess will not be there when you go back to the cave - this one had me puzzled for ages, as one of the possible responses is very similar to agreement, but isn't quite a promise that you will do the job.
