What is Cross Classing?
Cross Classing is a way of changing your characters talents away from the original path that you may have taken. For example a Warrior could change his class into one of the second tier Ranger classes at level 30 rather than continuing his path down the warrior tree.

How could this benefit my character?
Crossing with another Class allows your character to then use all three tiers of another class type as well as your original classes. For example a Warrior could change into a Ranger at the level 30’s class change and will then be able to use all of the tier 2 skills for the Ranger and Warrior, then on class change at level 40 use all of the tier 3 skills for the Ranger and Warrior also.

Please note any extra skills gained will not be kept, if you re-define your character and go into another class tree.

What downfalls does doing this have?
Cross Classing causes your character to not gain their level 30 and 40 class specific skills and / or bonuses. Although this does not apply to the racial abilities. If a Warrior chose to go Summoner or Driver they would gain the ability to Summon Animus rf online gold, or Pilot an MAU.

Once you have cross classed you are forced at the 3rd class change to choose one of the 3rd tier classes for your third class for example:
A Warrior chooses to Ranger at level 30 they would then be forced to choose a 3rd tier ranger class at level 40, even though this would not allow any class specific skills to be available to them, apart from the Ranger tier 3 skills.

Synopsis:
Choosing a Class other than your starting class affords you more skills than you would naturally be available to get, at the cost of your tier 3 class only skills and bonuses. While this can be alluring it is best to be careful and think wisely about what classes you choose to mix together.

PT's and Their Max's:
A characters PT’s will remain as their base class and if they Cross Class part of which what they would have cross classed into.

Staying within your original class tree you will be able to max all of your PT's no matter of type, e.g. A Warrior that chooses a Warrior class for the first job change (who is then forced to choose another warrior class at 40) will be able to max both Melee and Range PT's.
