The intermediate Gladiator vocation in Dragon Quest VII: Fragments of the Forgotten Past for the Nintendo 3DS trains up veteran fighters who learn very powerful abilities. They also learn useful specialized attacks like Metal Slash. They're not expert magic users, but most of their abilities use low amounts of MP, if any at all.
How to become a Gladiator: Visit Alltrades Abbey and make the switch after mastering the Warrior and Martial Artist vocations. Warriors are strong, sturdy fighters, whereas martial artists learn numerous body-based attacks designed to hone in on monsters' weak points.
Stat boosts and detriments: The Gladiator sees a big boost to their HP total, but the trade-off is a significant hit to their Wisdom and MP total. The boost to their Strength is considerable, and their Agility sees a little bit of an uptick, too.
Magic and Abilities Learned:
Level One: Gust Slash (A wind-based attack against a single enemy)
Level Two: Undead Undoer / Mean Sweep (Holy attack that does double damage to zombies, etc / An attack that may trip up an enemy and cause them to miss a turn)
Level Three: Gritty Ditty / Double-Edged Slash (A song that raises party members' attack / An attack that delivers 50% more damage to a foe, but causes you to take 25% of the inflicted damage)
Level Four: Toxic Dagger / Helm Splitter (An attack that may also poison the enemy / An attack that may lower the enemy's defense for several turns)
Level Five: Weird Wacker / Klepto Clobber (An attack that may cause Confusion / An attack that may steal an item from an enemy)
Level Six: Falcon Slash/ Metal Slash (Hits a single enemy twice at 75% strength / An attack that pierces the metal hides of armored enemies)
Level Seven: Multislice (Damages all enemies with a rain of blades)
Level Eight: Multifists (Executes four random attacks at 50% strength)
Usefulness: The Gladiator is an epic tank thanks to their high HP and defense boost. The Multifists ability chews up bosses if combined with Oomph and Sap. Again, Gladiators lack much in the way of magical skill, but their strength and innate abilities more than make up for their sparse spell selection. Metal Slash is a valuable asset when hunting down those tricky Metal Slimes and Liquid Metal Slimes.
