- Cost to restore: 10,000 crystals
- Location: Shell
- Effect: Neutralizes all other sealstones held by the user.
It is necessary to set this sealstone in a dais if you want to fight the Tyrannosaurus Rex Mini-Boss, as it carries the Elusive Air Law sealstone. However, this is the only instance in the game where it is useful, and there is no advantage in holding the sealstone. Therefore, as it is also very expensive, there is no need to restore it.
