Yes it uses the DB and is based on the difference in challenge rating and alignment ... so if you kill a paladin it will move you faster than killing the kids in the orphanage ...
only both seem to turn you good at the current moment... so far everything i kill turns me good, or my alignment keeps going up, and i killed a lot of townsfolk :twisted:
The only problem is that if you are lower than 15 ie 14 - 0 it will move you towards good until you get to 15. Once you are there it should not move you at all ( if you are killing good) try killing neutral or evil and see if you move up faster.. then once you are over 15 then see if killing good moves you down ...
You have to know that good is 85 neutral is 50 and evil is 15. This is set in bioware crap. I don't like it because at 30 to 31 and 69 to 70 it moves you to 15, 50, and 85 depending on if you are turning good, evil or neutral.
I am going to test some of this tonight .. please see the post in the world status to see how it works ...
