Has anyone ever tried this?

I made a 10 charisma character and tried to read the your special book to get it to 11 and then use the bobblehead to get it to 12.

But that didn't work

So I tried getting addicted and gaving the -1CHARISMA so I only had 9 CHarisma when I read the your special book). But this also wasn't good.

THen I tried daddy-O to gave -2CHrisma and that did work getting a base of 11 charisma without the bobblehead.

So you can get 1 stat that's standard 12 in stead of 11

(I know you can get str12-ENd12 with a solar powered and PE12-INT12 with night person)

By this logic you can put the following stats on 12

STR (daytripper)

PE (fury)

CHR (as said before daddy-o)

INT (drink most types of alcohol)

Of these CHR seems the most useful because you can have 30 more settlers and trade becomes easier

INT seems the least worthy because it gives no real bonusses

I don't believe you can use the special book to raise a stat above 10.

But I could be wrong... I can always test that tonight since I have not bothered using the my SPECIAL book yet on my level 70 character. I'll simply use console commands to raise a stat to 10, then I'll try the book.

Having a "natural" 12 in charisma would be very convenient though. Based on my limited testing when looking at the price of the Overseer's Guardian, it seems the best vendor prices can be had with a charisma of 12. Anything higher than 12 appears to be "wasted".

There is an aid item called drugged water, it stacks with itself and allows you to low Per unlimitedly irrc, so you can use copied water and the book to raise your stat as high as you want, allowing you a 100% hit chance in vats regardless of any and all situation, with penetrator giving you the ability to shoot through walls you can become death, the destroyer of all

The point of the OP was that using Daddy-O to bring your charisma down lets the book's buff work. When the drug wears off, boom, 11 charisma.
