There is no advantage to holding this sealstone, but it can prove somewhat helpful on a dais if you do not have any other negative sealstones to use. Its location on top of a high ledge means that you will need to obtain Powerless Pigeon Wrath to be able to reach it, meaning that it will probably be the last sealstone you get. Considering that it is one of the most expensive sealstones in the game, and that, by the time you reach it, you will either have finished the main storyline or only have the final boss left to battle, it is not worth restoring.
