There is no advantage to holding this sealstone, but it can be interesting when set in a dais. However, it is one of the most expensive sealstones in the game, and it is not necessarily worth the trouble of farming Magic Crystals. It can, however, be used to help in the various boss fights in the Ancient Forest (Cybersaurs, Griffon, Kobold King).
