How do you get a specialization in Dragon Age Origins?

Answer 1

On their level up screen, the specialisation screen is on the first page opposite the statistics. Keep in mind that a specialisation can only be granted to a character once he or she reaches level 7, and then a second at level 14. Also note that the joinable NPCs can't be given one until Lv14, as they all start out with a specialisation already (except for Sten, but he only gets one in total, at Lv14).

Answer 2

Wait until level 7, then you have to do one of the following.

1)Buy a tome.(Easiest but most expensive)

2)Ask a party member to train you in their specialization.(2nd easiest, but limited.)

3)Find an NPC to teach you.(VERY VERY HARD, but free, and not that limited...)(i.e., desire demon in the fade teaches you blood magic if you're a mage.)

That's all that I know.
