Many thanks to Irisis for this tip : “Thisalee Crow located in the Molten Front, Go to The Furnace. Let the fire kill you right above the covered hole right above the molten flow, die in the fire and before you die do a death jump near the covered hole. You’re ghost will be able to run through the hole and you rez right before you land. If you do it wrong return to the graveyard and try again. She is located in the bottem of it, talk to her and you are one step closer to being done!” – Irisis
