In Dragon Age: Origins, characters are given three attribute points and a talent pick with each level gained. A skill pick is received every three levels for mages and warriors, and every two levels for rogues. Specialization picks are received at levels 7 and 14.

Advancement beyond level 25 is nearly impossible in Dragon Age: Origins, but you can easily reach level 30 and above with the Awakening expansion pack. As you can see from the table above, the experience requirement simply increases by 500 points each time a new level is attained.
