- Cost to restore: 20,000 crystals
- Location: Held by a Mini-Boss (Wild Troll).
- Effect: The user's non-elemental damage becomes Earth-elemental. The user also absorbs Earth, but gets -100% resistance to Lightning.
This sealstone could theoretically be useful in a dais if you have the means of absorbing Earth, but it is probably more trouble than is worth. Moreover, it is very expensive to restore, and Earth protection can later be achieved by other means. Holding it also offers no advantage, as enemies in this dungeon use both Earth and Lightning attacks.
