Gems in Wartune are used to enhance equipment within the Blacksmith. A gem can be placed into any equipment that has open sockets. Only one of each type of gem can socketed in each piece of equipment. All gems have a level ranging from 1-10 that determines the quality and bonus stats given when socketing them. Gems can be synthesized into higher level gems using 4 gems of a level lower then the one you are trying to synthesize. Gems can be converted into other types of gems of the same lvl using the convert option in the blacksmith interface. In order to be able to create gems of higher levels past level 4 requires Transposer Scrolls. except for Patk, Matk, Mdef, Pdef which can be received from Campaigns. One you have gained a scroll you have the ability to create that gem forever. Other Transposer scrolls can be purchased from the shop for Balens. Soul engraving directly effects the bonus received from gems based on a set % based on its level.
