This mob is a very, very rare spawn. It took me two days of clearing the house she spawns in for her to spawn.
Location of Spawn:loc -1040, +1710
Looks like:Female Erudite, same as the tavern wenches in Dulak and the rest of LoY.
Easily killed by my level 55 Magician and my trusty air pet. 3 waves of 680 damage(Sircoo) took her down about half health or a little less, pet finished.
