Hmm, I saw this pop up then forgot about it, will definitely try out the NI maps.  Randomized of course 
 
Enchantresses have been my saving find more-so than any other.  I've had bad luck with sorceresses getting old, even more than sages.  I did use the onyx (amazon?) sorceress in the last game to kickstart a weak blood economy with a rainbow pretender.  Before that, never used em.
Enchantresses are pretty expensive, but worth it for the automated site searching and the 2E + boots blade winds.
