Classes: Cabal online has 6 classes to chose from. They are:
Warrior- Warriors are the main fighter class who specialize in the use Aion Gold of heavy armor (Armorsuit) and huge 2 hand swords (Great sword or Dai Katana).
With high hp, def, and physical strength, they are good at both PvP and PvE solo. But that does not make them the best class, though it makes them very good for new players or fans of 2 hand swords.
Blader - Bladers are the fastest (atk speed) melee characters. They use a combination of light yet maneuverable armor (Martial suit) and 2 one hand swords (Blades or Katanas).
Having light armor they have less "def" but way more of a dodge rate. They make great PvE and moderate PvP depending on how you train them. This makes them a wise class to pick if you really like PvE or duel wielding.
Wizard - Wizards are the basic magic class. They use what are called "orbs" which are used as magic amplifiers, and light armor (Martial suit).
Orbs attach to the character's wrists, and the orb on the right wrist summons a staff (mostly to make them look like they use a weapon/ also the cool factor) later on in the game they have incredible (both look and power) magic attacks/skills some of which have huge AoE (area of effect).
The next 3 classes are classified as "Force" classes. Force classes are more like hybrids and they are.
