I just started making new character and want to know if leaving charisma at 1 is a bad or good idea I know int been nerfed to half points for int but I still want to be able to max 5+ skills and be able to survive I will be using guns and energy weapons. If anyone has any comment about this build feel free to give any opinons.

Strength - 5
Perception - 7
Endurance - 5
Charisma - 1
Intelligence - 9
Agility - 7
Luck - 6

I went with:
Strength - 6
Perception - 6
Endurance - 6
Charisma - 1
Intelligence - 9
Agility - 6
Luck - 6

and it's working okay for me.

You can take your luck down to 5 unless your trying oo get a certain perk. Also know that you can get implants at the NV medical center that give yu a +1 in any SPECIAL you want.

I want the better critical perk which require 6 luck I have not progressed so far in game where is the person that sell the implants because then I could lower my luck and get the implant early if it possible?.

You should both have the caps and be friendly enough with the followers to get a implant before level 16.

Also note that you can only get as many implants as your endurance allows. in other words for Evey point of endurance you can get an implant. Also there are two implant that don't effect your SPECIALS. They add DT and regenerative health.

Well I decided to make his endurance 6 and have 5 luck then get implant to make endurance 7 and then get one for luck.
