Could always tweak the mod yourself afterwards to add/remove/tweak things to your own liking.
Personally I would've wanted to alter AGI so that it increases jumping height very very slightly as well as running speed by like +5% for every point above 5 but alas I'm too much of a lazy piece of shit to redownload the FNV GECK and do actual work.
Well would you look at that, I already had FNV and GECK installed. So let's see here...
Huh, neat, I think I found where to edit the derivative statistics of SPECIAL. (go to the "Gameplay" tab, go to "Settings", search for something like fAVDCritLuckBase and you'll see it is at 0 and if you search for fAVDCritLuckMult it shows 1, so base crit is 0 and each point in Luck adds 1%. So that's how you tweak derivative statistics) I also found where to edit the description of individual SPECIAL stats. (Go to "Character" tab, go to "Actor Values" and look for the skill or stat who's description you'd like to alter) I have yet to find how to add something new and tie it to a primary stat though.
