Geometer

From DevroWiki

The geometer is the master of written magic and spells inscribed within a perfectly rendered diagram. Some members of the Tribunal of Arcane Law find the use of sigils and glyphs rewarding, as they are fairly common and powerful magicks, especially in some of the ruins across Devro. The spell shorthand taught by the Geometers, while difficult, is also a tremendous draw to mages and specialists.
