I am very new to the game.I needed to set my intelligence on 1 for my build.Now i can't take lots of missions cuz im so dumb.Are there any ways to get some more intelligence?
Your problem is that you listen to the pvp apes, because there is noone else to give advice.
For a new player, average stats, with high end and agi, with 5-6 int is best. Simply because you can re-roll later with a book of achievement for 10k caps and remake your char, and until then you can enjoy the game.
Charisma is useless, so leave that at 1, the rest as you feel like, easiest to level and enjoy game early is: medium STR(5+), PE(5+), INT(5-6), High AGI(10) and END(
min CHA (1) and divide Luck, move a few skill points by preference. If you can make out with 3-4 Luck that is just fine.
Traits: Fast Shot(unless you go sniper, which I dont recommend) and another one, or just leave the second trait empty if you don't find any suitable.
Skills: Small Guns, First Aid, 3rd your choice, can go for BG as well, but level SG first to 175~180.
Perks:
For extra stats: Weapon handling/Sharpshooter depending on your stats.
Even tougher/Lifegiver for survival (if go full tank, take adrenaline rush and tougher as well, with CA almost nothing will hurt you from NPC's)
Even More criticals/Action Boy/Bonus rate of fire for damage dealing.
The rest as you feel like.
Also you might need to level lockpicking to 100 and carry some lockpikcs, they are cheap to craft. (In urban area random encounters where there are NPC's as well, sometimes (50%?) a white lockbox appears, that you can pick for random, sometimes good, stuff.)
Raise doctor to around 50-75, in case you get crippled, but focus on SG first.
Get caps by selling stuff to vendors, and buy some book to raise Repair and Science to craft, or spend some skill points.
Note:
You can make 1 int builds when you feel ready to PvP. For that, make an alt, keep this char with ur bases and help him with stuff, craft, etc.
