Castle Watering Hole

To reach this Site of Grace, you need to use the Coffin in Shadow Keep.

To reach it, Head back down the elevator from the First Floor Storeroom Site of Grace and leave the Keep, then turn to your left and you’ll find a ladder leading down.

Follow this walkway to a waterfall which has another ladder hidden inside. Take this down to the bottom and enter a room with a painting, look to the south wall to find an illusionary wall (strike it with a weapon) and follow the path to the Coffin.
