Jinn Crystals are dull blue crystalline rocks in rough form, becoming a translucent bluish crystal of incredible beauty once refined and polished. The crystal is usually found in underground caverns in small, naturally-formed deposits. The perfect crystals are required as a focusing device in the production of a variety of advanced pieces of technology of Telepathic nature. The slightest trace of impurities will ruin the crystal's use as a focusing lens, rendering it useless. Jinn Crystal deposits are incredibly rare, but fortunately 1 ton can be created by purifying 10 tons of Raw Resources.
