A Martial Artist will sometimes go into a long period meditative isolation and re-emerge capable of dramatic feats of combat skill, earning the title of Monk. Monks achieve greater insight to the workings of their inner energy (or 'Ki') than the average bare-knuckle brawler, using it to heal allies, boost their own abilities or just kick people so hard their liver flies out their ear.
"You call dropping suns a martial art?" -- "Hey, as long as it works!"
Wide array of skills and capable of adapting to a variety of combat situations. Monks often vary from being Damage Dealers, Tanks, Dodgers, Supports... Or all at once!
Body of Isesip makes a Monk able to negate damage up to 3 times, it is definitely a great tool to fight against some Evokers or Excel Weapon users.
Monks with enough WIL can also slightly heal their allies with Aid and offer them Woki whenever they're around.
Power Up offers them an almost limitless source of FP recovery, but only as long as you have the Momentum for it.
Ki Awoken is the ultimatum of a Monk's arsenal, your HP will be rapidly depleted over, time but all of your statistics will greatly increase for the duration. Hooryaaaah!!!
They can be every combat role at once, but as a class, they don't specialize on anything in particular.
Ki is another resource that needs to be managed, so a bad management of Ki can ruin their damage/utility sharply, and Ki is easier to be spent than generated
Several stats must be raised somewhat evenly to get full use from all Monk skills.
Using Power Up at the start of a fight makes them susceptible to being rushed by Duelists, Archers or Soldiers who doesn't need to waste a round preparing, as the Monk will lose one whole round for it.
