This does not drop off Hierophant Vradik, although it does drop in the third room after you come out of the water, or the bathhouse as I like to call it. I may have these backwards, I can't remember for sure, but there are two Hierophants that spawn, one here and one in the room across from the shop. Pretty sure Ginai spawns here while Vradik spawns in the other room, but I may have them backward
Pher is " A Seer" , pops in the 3rd room after the water tunnel , has a big pool in the middle , just before you run into the golemns. Pops in front of the huge unopenable doors opposite form where you enter the room.
