In fallout 2, the zeta scan you can do in NCR I have been told increases your luck by 2, however every time I do the scan it decreases it by 1! Is there a variable that changes this? Or is there a specific dialogue tree that you have to follow? My luck is 6 if that helps.

The Zeta Scan is totally random. All you can do is reload your game and try, till you get +2 luck.
