* How to get achievements? *
Just load the save and talk with the NPC in front of You.
*For skills achievements there's one last locked skill that You just have to unlock.
*For fraction skills just join the fraction by talking with NPC.
*For Balance of Power achievement You should talk with the beggar and finish the quest in which You have to defeat 3 enemies. Then talk with the beggar again and leave Abessa City.
*For the Picture Album achievement it should trigger when You pick up the photo located in front of You.
* Note *
The Picture Album achievement could trigger Calaan achievement as well but I can't test that because I've
already unlocked these achievements. Also it could contain spoilers for
the quest in which You have to find Calaan.
