- Cost to restore: 30,000 crystals
- Location: Held by Mini-Boss (Persistent Pursuer)
- Effect: User's non-elemental damage becomes Darkness elemental. User also absorbs Darkness, but gets -100% resistance to Holy.
This sealstone could theoretically be useful in a dais if you have the means of absorbing Darkness, but it is probably more trouble than is worth, especially considering that you may want to avoid fighting as much as possible during your first trip through this dungeon, due to the timer. Moreover, it is one of the most expensive sealstones in the game and therefore not worth restoring, especially since you can achieve Darkness protection by other means. It can be useful to carry if your party has a strong elemental build, but will otherwise hamper your effectiveness in combat.
