Flame User class series

The Flame User class series is the default class series available to the Mars Adept Jenna, who is under the influence of this class series if she either has only Mars Djinn or no Djinn set onto her. The Flame User Class series is unique to Jenna in Golden Sun: The Lost Age, as she is a mage while Garet is a fighter. Garet has a different Mars-based class series unique to him, the Guard class series.

Jenna as a Flame User was available in the Sol Sanctum dungeon at the beginning of Golden Sun; however, she only had access to the Flare Psynergy series and could not change her class because there were no Djinn available at the time. The rest of her classes and Psynergy were revealed in The Lost Age.

The class series, when at its highest stage of Justice and compared to the other series at their highest respective stages, has good Agility, above average PP, and average HP and Attack, but lower Defense. This series' luck rating is below the standard. Noteworthy Psynergy from an endgame perspective include Cool Aura and Dragon Fume, and the heaviest area-of-effect Psynergy it has is Searing Beam. Average stats from an endgame perspective are 145% (156% if you don't factor in Luck).

Statistical Influence
Carlin (the Japanese name for the Hex class) is a Scottish term for a woman, particularly an aged one. The intent might have been "wise woman", considering the presence in the Japanese of a "Sage" step (the equivalent of the Justice class).

Analysis
With some hard hitting Psynergies, a reliable group heal series, good agility, a fair sized PP pool and her innate ability to equip Light Blades (which will serve to augment her average attack), Jenna's Mono-elemental class is one of the best mono-elemental classes out there, and leaving her in this class is a solid choice. When compared to the Flame User class, her Duel-Elemental class lineup (Brute class series, Swordsman (Mars) class series and Page class series) is actually somewhat more detrimental then helpful, and it is best to run her straight into the Tri-Element classes then deal with the Duel-Element classes.

The biggest thing to watch out for is the PP pool in the later levels. While 160% PP stat is nothing to sneeze at, Searing Beam and Dragon Fume are among the most expensive Psynergies in the game, weighing in at a whopping 36 and 35 PP respectively. Only Spark Plasma and Thunderhead are more expensive. Also, Jenna can only equip clothes and robes so her average defense stat will be just that: average.
