Profession?¿?

Can your character only be two professions? If not then how do i get other professions?

You have a primary and secondry profession... eg Warrior primary, Necro Secondry aka W/N

You can freely change your secondry profession later on in any chapter, to any profession you desire aslong as you have the correct chapter...
If you want to change to change your primary profession, only way to do that is delete your character. Or just make a new character as you can make it up to 4/6/8+ depending on how many chapters and slots you have purchased.
