The Dragoon class series is a tri-elemental class series available to the Venus Adepts Felix and Isaac, the Mars Adepts Garet and Jenna, and to a lesser extent, the Mercury Adepts Piers and Mia. Mercury and Mars Djinn are required for the Venus Adepts, whereas Mercury and Venus Djinn are required for the Mars Adepts. The ability to access this class by Mercury Adepts is a vastly overlooked quirk in The Lost Age, and requires Venus and Mars Djinn.
