Info	The hidden monument with a cloud you are looking for is a grave stone located northwest or northeast of the Giant Sheep Mark in Muyu Desert. A circle illuminates on the grave stone while it rains, which is the only difference visible to players. The grave stone moves every time it rains, ensuring that you will have to find it twice.
