*Spoilers below:

I am just wondering when you get the ranger character. I'm not quite sure how you get the ranger as it doesnt even state him or her on the character class page. I just want to know what level/requirement it takes to get the character, any info would be cool. Just figured i might as well try out the ranger since din's curse is going to have that character which is going to prally be my main character in that game.
