A tethered gemstone is used to store a spell in reserve of a particular school of magic. During its original construction, the type of gem determines which of the four main aspects of magic it is suited for. Emeralds for Druidic, Sapphires for Bardic, Rubies for Arcanic, and Diamonds for Holy magic. At tethered gemstone is not tied to the caster, but can only be activated by someone in with magical ability of that type. The results of the spell are no different than if it was cast normally. If the user cannot cast the level of spell contained in the gem, there is a chance for error and possibly immediate destruction of the gem itself. Tethered gemstones can be found in two different qualities, lesser (stores spells up to 4th level) and greater (stores spells up to 8th level).
