With the Intense Training perk, you can put a single point into any of your S.P.E.C.I.A.L. attributes.”— Fallout: New Vegas
With the Intense Training perk, a single point can be put into any S.P.E.C.I.A.L. attribute. Each point will be fundamentally identical to a point that had been allotted during character creation, and so will allow the player character to gain more implants (Fallout: New Vegas) or perks.
