Fractals

Fracti are precious stones that rate above and beyond normal gems. Found only in the frozen north surrounding the Crystal Empire, these gems are rare enough that they valued above all other mundane treasures. Chief among their properties is the unique enchantments that possible with these gems.

Imperial Fractos
These crystals are found in the Crystal Empire's mountain range and are the most common of the three Crystal Fractos. Their primary use is taking the energy normally spent from spells and amplifying or augmenting it in useful ways, above and beyond what other magical items would normally do..

Sombran Fractos
Sombran fracti are usually a dark purple with veins black and are most often found deep underground in the arctic tundra. Their primary use is the ability to bind outsiders to take advantage of their inherent magic.

Game Attributes
Fracti, like most gemstones, have a hardness of 10 and hit points equal to 20 per inch of thickness. Their value is proportional to both their size and their clarity. When found, most fracti range in value between only 50 gp to sometimes as much as 5,000 gp.

Availability In Game
Dragonshards are rare enough and valued highly enough that, as a rule, players should never be allowed to simply buy them. The market for crystal shards has been monopolized long enough by the Crystal Ponies that a fracti's price should be multiplied by at least 1.5. Copied from the Eberron dragonshards found here.
