I share your frustration The_Cannibal. I brought this gsme at launch on ps4, and I am still yet to see her. Not even so much as one-single-blinking-time!! And Ive been trying to collect all T4 female dancers for some time now.
Can anyone suggest any other spawn points? The only one I know of is the Shrine of the Oracle, near Vathis the Heirophant.
