Expertise

Expertise is the game's core character advancement system; it is by raising expertise that your character learns new abilities.

Expertise is raised by using abilities associated with them. For example, by casting Destruction spells, you will increase your point value in the expertise. However, expertise will not just rise on its own. You have to specify which expertise you want to raise.

Click "PC" and then "Expertise" to open your expertise window. A gray button with a line means the expertise will not go up. If you click that button, it will change to a red arrow, which means that expertise will go up when you use the right skills. It is important to note that you cannot max out every expertise, so you will need to choose what areas you want to focus on.

Your maximum expertise is 17,000 + (Floor(Level / 10) * 1000). Thus, by reaching level 90, you will reach the cap of 26,000 expertise points.
