Job Classes:

Magician:
A caster class,weak to melee,try not to get in melee range,or use melee attacks
always keep using your spells to keep distance,and then use your spells to do massive damage.

Acrobat:
Another job using ranged attacks,mainly using a bow,or maybe a yoyo(lol )
with fast,ranged attacks

Assist:
Being an assist, you'll be able to choose to either be a fighter, or a healer. If a fighter is what you desire, assists generally have up close, and personal combat. As you progress, you will find that using certain skills you will be able to destroy all enemies at once. If Healing is more your style, you may choose the alternative. By using a magic stick, you will be able to summon magic spells to enhance the abilites of those around you.

Mercenary:
A close-combat job,not using ranged attacks or spells,mostly strong armor and high hp,and high defence

Second Job Classes:

Jester:

Jesters focus on ranged attacks using Yo-Yos and Bows. They have a wide range of skills that allow them to be strong PvP'ers with their YoYo attacks, use some of their penya to do increased damage, and escape incoming attacks.

Ranger:

Rangers are a ranged based melee class that focus on using bow skills to damage enemies. Coupled with the Dark Illusion Acrobat skill, Rangers can make a great PK support class as enemies will be silenced, and will not see you attacking.

Billposter:

Billposters are one of the only classes that are self sufficient. With their normal assist buffs, and then added damage skills upon second job change, they are a very strong class. They are more of a melee class, and fight using a knuckle and a shield.

Ringmaster:

Ringmasters is the other class that an assist can choose from. When it comes to parties, this class is the most sought out after due to their ability to enhance others skill. With extra buffs and skills, this assist class is almost considered a necessity for gameplay, or at least they make it easier.

Psykeeper:

Psykeepers are another one of the magician's second class. These, however, do not deal in the field of elemental damage. Most of the attacks, which are very powerful, tend to be based off mental and demonic forces.

Elementor:

Elementors are a second class for magicians and are a high damage spell casting class which use staves to cast elemental spells. They have to their disposal a wide range of elemental skills which can damage one or several enemies at the same time, or self buffs to increase the damage they deal.

Blade:

Blades are a second class for mercenaries and are the best damage dealers in the game. As a blade you will be able to wield two weapons at the same time and highly increase your damage .

Knight:

Knights are a second class for mercenaries and are the best tanks in the game. As a knight you will receive more health points per stamina point than any other class.

NPC:

NPC's or Non Playable Characters are the people inside the world of FlyFF that give you quests, sell you items, buy your items, and help you create guilds.
