I think I beat Josephine around level 35 and it was a close win.
The Holy Amulet is just to your east when you enter Elven Ruins from the center entry. There is also a cave entrance which leads to Elven Ruins too. But that is not the entry I mention. If you found the Elven Ruins teleporter, the entrance is directly to the north of it.
I am sorry, I can't give you a screenshot. You can look for Dark Forest map. Dragon has one around here, just search the threads.
