Intense Training? Dur Dur...
Intense Training is a perk with 10 ranks (meaning you can take it ten times instead of selecting an alternative perk), and each rank allows you to increase a SPECIAL attribute of your choice by one.
So, for example, if I hit level two, I could decide to take Intense Training level 1 instead of Black Widow or one of the other level two perks, and put one SPECIAL point in strength. Or agility, or perception, or luck.
It's a trade-off, however, because I'm skipping an 'active' perk to boost a SPECIAL stat.
