Incidentally lore-wise Conjury is actually called 'geomancy' in Doma - the Swallow's Compass actually has GEO enemies in there who cast their own unique versions of water, wind and earth spells, but there really isn't much that sets them apart from CNJ anyway so that's why GEO hasn't been added, it's already technically in the game anyway (and ignore Gaia, her use of a hammer was simply a mistake on Tetsuya Nomura's part who was unaware there wasn't a hammer using class in the game, which Yoshi just left in simply "because it's cool").
