Ninja class series

The Ninja 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 limited extent, the Jupiter Adepts Ivan and Sheba. The Venus Adepts will be under the influence of this series if they have both Jupiter and Mars Djinn set to them; similarly, the Mars Adepts become this class when they have Jupiter and Venus Djinn set to them. The Jupiter Adepts can only access the Ninja class, and require Venus and Mars Djinn to be set to them. The access to this class series by the Jupiter Adepts is a vastly overlooked quirk to the Ninja class found only in The Lost Age.

This class series is very similar to the Dragoon, Ranger, and Medium class series in structure.

Psynergy Setup
In Golden Sun, Thunderhead was called Thunderstorm. However, that name caused problems with fitting text into single lines, so it was changed to the shorter Thunderhead for The Lost Age.
