Swordsman Class Djinni Composition

The Swordsman Class in Golden Sun is primarily available to your Mars Adepts Garet and Jenna. You're also able to become a Swordsman on your Mercury Adepts Mia and Piers but only once you've stacked 6 or more Djinni of the opposite school.

I would recommend avoiding trying to make your Mercury Adepts into the Swordsman Class though as it requires many Mars Djinni in order to accomplish this task which will severly limit your other possible group compositions.

Mars Adepts: 1 Mercury (Swordsman)
Mars Adepts: 2 - 3 Mercury (Defender)
Mars Adepts: 4 - 5 Mercury (Cavalier)
Mars Adepts: 6 Mercury; 1 Mars (Luminier)
Mars Adepts: 7 Mercury; 2 Mars (Radiant)

Mercury Adepts: 6 Mars (Cavalier)
Mercury Adepts: 7 Mars; 1 Mercury (Luminier)

A Swordsman is quite the well rounded class. They come with a decent boost in attack rating and have a fantastic mixture of offensive and defensive abilities. Ply is learned as early as level 1 with their first group heal being learned at level 8.

In addition to regular and group heals this class also receives the Protect Psyenergy which will boost your allies' defensive ratings. If you're curious about the other abilities available to the Swordsman class take a look below for a full writeup.
