Signeturgy is a unique type of sorcery in Star Ocean: Integrity and Faithlessness only practiced on the continent of Vestiel, where Fidel and his group are from. Similar to Symbology, specials "Signets" are activated to create magical effects. However, unlike Symbology, these signets are physically imbued onto a person's body, glowing when they are activated. Because of this imbuing process, Signeturgy is generally only performed by adults who can withstand the painful experience.
