Brute class series

The Brute class series is a dual-elemental class series available to most Venus and Mars Adepts. These Adepts become members of this class series when Mars or Venus Djinn are set to them, although Venus Adepts rely more heavily on Mars Djinn and Mars Adepts rely more on Venus Djinn. As of Golden Sun: Dark Dawn, this class series is available to Isaac, Felix, Matthew (all Venus Adepts), Garet, Jenna, Tyrell, and Eoleo (all Mars Adepts).

Because the two elements involved, Venus and Mars, have a symbiotic relationship, an extra class level exists in this series compared to other single and dual-elemental class series, making this class series very powerful. This is much like the Hermit class series, shared by Adepts and Djinn of the Jupiter and Mercury elements.

The class series, when at its highest stage of Chaos Lord and compared to the other series at their highest respective stages, has excellent HP (tying with the Master and Paladin and surpassed only by the Ronin), superb Attack (tying with the Master for the highest attack rating class increase in the game), and good Agility, but lower Defense and very low PP. The series has the lowest Luck rating of all class series. Noteworthy Psynergy from an endgame perspective includes Revive and Planetary, and the heaviest area-of-effect Psynergy it has are Stone Spire and Supernova/Inferno. Average stats from an endgame perspective are 143% (158% if you don't factor in Luck).

Psynergy Setup

 * Note: Blast, Nova, and Supernova are replaced by Fireball, Fire Orb, and Inferno in Golden Sun: Dark Dawn.

Analysis
Boasting the highest attack in the game, with a fair agility stat to run with it, the class can dish out some good damage, especially for characters who can use Long Swords. As well, on the Psynergy front, the class has some hard-hitting abilities and the extremely notable Revive Psynergy, but the low PP rating should be noted. The Adept's PP meter may be somewhat strained without proper support like from PP-recovering Djinn to use these abilities, so it is most recommended to use the class as a base for a 99%-Meggido Sol Blade setup with Isaac, Felix, or Matthew. Incidentally, the Chaos Lord is for many intents and purposes directly superior over the Slayer class of the previously-mentioned Adepts' default Squire class series, since it also has Revive, and has an additional 10% of HP, an additional 20% of Attack, and an additional 10% of Agility to offer, with neither the PP and Defense ratings lower than the Slayer.

Trivia

 * As of Dark Dawn, the only Venus or Mars Adept who cannot access this class series is Himi, who instead obtains the Curse Mage class series.
