Down in the dungeon area (where the lava pit is) there is a treasure chest with a holy relic. Get the relic, take it back to the lich, Cet will come and destroy the lich, get his snakehead staff. Then take the staff and use it on the stone face lock. That is where the vampire is that you have to destroy for one of the multitude of quests within this game.

Hello, this lock is in the area of Skull where you have to get all 4 of the up/down bridge stones to line-up so you can cross them all. What does one use to open this lock?
Thanks for any help,
Moors
