This may sound a bit newbish but...when and how do you get to pick a subclass? Like if I am a mage, when will I be able to pick to be a summoner then conjurer? It's levels 10 and 20 right?
At level 9 you will automatically get a quest (level 8 and you can seek the quest out) to speak with someone about becoming your next class. Same goes from level 19.
