This sealstone could theoretically be useful to hold if you are planning an elemental build for your Archers (although Light Warriors and Sorcerers could also benefit). However, several enemies in the dungeon are Holy-elemental, and elemental builds lose a lot of their usefulness this late in the game anyway. You may, however, want to move it to a shell to weaken enemies, especially if you are not confident in your ability to avoid attacks.
