This sealstone could theoretically be useful to carry if you are not confident in your ability to avoid enemy attacks, but even then, it is only circumstantially helpful. It is obviously detrimental if set on a dais, so leaving it in a shell or restoring it to increase the withdrawal limit in the dungeon are probably the best options, especially as it is cheap.
