EXP / Attribute Points / Skill Points: Changes take effect when the value gets modified by the game itself. Means editing EXP requires you to gain EXP ingame before you see changes.
Fast Skill EXP Gain: While active and you use a skill and get EXP, the skill EXP will be heavily increased.
Gold: You need to buy or sell something first. Then make your changes. You will need to get or spend money again to see changes.
