Please tell me (Dragon Age 2)

which file needs to be edited to increase / decrease experience points for lvl. and the addition of points of characteristics and abilities. downloaded the file for 50 lvl., but XP is cut 2 or 3 times, i.e. from the transition from 6 to 7 lvl by default, you need 6000xp, and with this file 1800. This is completely sad. And 11 points each. character. this is too much. Help kind people.
