Common Gems

Common class gemstones are used in Stone Casting. Being the most common of the four gem classes, there are countless gems that fall into this category, some even related more to common rock than to gems. There are countless uses for these gems, however they are all paltry and can only accomplish the most basic of spells. Therefore, these are used mainly for mages who need to either feed a longer line of power into a larger spell or accomplish something simple, like identifying a falsely lit stone.

Coal, being the most abundant resource in the nation, can be used in incantations. This is notable because it has become common practice for hack Stone Casters to use the abundant supply to try to obtain and use more powerful spells by ingesting unhealthy amounts of the raw material. This leads to some of the worst cases of stone sickness the Watchers have recorded.
