Blue Opals

A form of opal that enhances the abilities of aquamancers. While not all opals of a blue color will enhance the aquamancers' powers, this magically charged form will. One can tell the difference from the color the opal flashes. If it flashes blue and purple, it is a good quality of magic opal. Green means its power has been partially used up. Red and orange is an ordinary blue opal, pretty but useless for the purpose of magic.
