Shadow Gem

Origin: Shadow Gems do not occur in nature but are created by the Dark Gem.

Uses: Shadow Gems are used by wizards and magicians in spells and potions. They are also used by weapon smiths to make powerful weapons.

Additional Information: Shadow Gems are weaker than the Dark Gem, but since there is only one Dark Gem, they are covoted by whoever can get their hands on them. An imperfect recipe to synthesize your own Shadow Gems does exist, but Shadow Gems that are created this way cannot bear the same strain.
