Multiclassing

Multiclassing
In DDO you may play a character belonging to many classes at the same time. This is called multiclassing. You first create your character as a single class. Later, when you obtain enough experience to make a level you may pick a level in another class. You may have a maximum of 3 classes on a single character.

Skill Points and Multiclassing
Max Ranks: If a skill is a class skill for any of your classes, then you can have (character level + 3) ranks in it.

Cost: If a skill is a class skill for the class you are gaining a level in, each rank costs 1 skill point. If the skill is a cross-class skill for the class you are gaining a level in (whether or not it is a class skill for one of your other classes), each rank costs 2 skill point.

Enhancements
DDO adds another avenue of character advancement, the four enhancements. The less useful enhancements open to multiclassers gives another large drawback to that kind of build, multiclass enhancements.
