(early-mid game) STR 6 PE 6 END 8 CHA 1 INT 8 AG 9 LK 9 therefore, our build will in fact be like the following: Instead, get the sub-dermal implant for +4 DT. You can improve all of these +1 at the Followers Clinic. (initial) STR 5 PE 5 END 7 CHA 1 INT 7 AG 7 LK 8
There are many ways to approach the game. This is NOT the best build ever, nor does it claim to be. Lots of factors play a role, like having experience with the game, knowing how to approach situations, knowing where to go early/later, knowing where the mines and the ambushes are, knowing where to never fast travel to etc-etc. Note that the build on its own does not guarantee success. Other design mod I used was Economy Overhaul (it makes the economy tougher and therefore the Barter skill useful). This is the Guns build that helped me do a full 150h ironman playthrough of New Vegas + dlc + Josh Sawyer Ultimate Mod on Very Hard/Hardcore.
