Here's my favorite drunk brawler build
Str 6
Pe 5 (For awareness)
End 6 (You'll be taking extra lifegiver anyway)
Ch 3 (You can't very well go into a bar looking like a POWERBUILD)
Int - x ammount left to be dumped into FA/DOC when you're down on your luck.
Ag 7 - 8 (with small frame taken it will be boosted to 8 and dump that extra point into w/e)
Luck 6
good natured
-unarmed or melee
-speech
-gambling (useless skill just to be funny)
Now you can stumble drunk into the Den, catch yourself a nice Nuka cola while kicking people in your drunken rage for losing at that nice roll on the table.
