I made a fatal error in the distribution of S.P.E.C.I.A.L...

Now being lev40 and running out of ballistic customisations I want to spec up some energy weapons and some of the power armor sets but I have but missed that these are part of the Science! perk, not the Armor/Gun Nut perks.This is grossly annoying as I think I am roughly through 50-70% of the main story line and would like to keep the momentum going.

I feel I already know the answer but is there any way to redistribute attribute points or any of method of being able to obtain this one particular perk? I am currently relying on enemies dropping weapons/power armor pieces with parts upgraded beyond my ability.

Also...whilst on the subject, I haven't wasted any level up points on the actual header item (e.g. Intelligence), what exactly does this do?

The header item increases the stat by 1 for 1 perk point. The only other ways to increase a stat is to find its Bobblehead or use the SPECIAL increasing book in Sanctuary.

you can raise your int like how you raise your perks level. assume you have hacker you only need 2 level to raise to science and 4 level of science to max it which mean 6 levels.

Ah right so I'm INT lev5, you're saying if I assign 1 point into INT itself that will give me Science!, then the next 4 points I can use to get that to rank 4?

yes

It won't give you Science! It will just let you pick Science! the next time you level up. Aside from that distinction, your assessment is correct. The next four points can be put in Science!, assuming you meet the level requirements (which you should at 40 or whatever you said).

Don't forget you can get the Science Bobblehead if you haven't picked it up yet if you don't want to use a perk point.
