If you make a female character you could take the Black Widow perk at level 2 thus pushing all the other perks down one and you would also have to sacrifice one of the perks along the way to make room for it I suggest sacrificing the Animal friend perk. As a personal preference I always take the Animal friend perkX2 because I like it when the Animals come to my aid and then just stand there after the fight while I kill them for extra experience points.

Note: Do not take the Four Eyes trait because even with glasses on your base perception is going to be 1 below your actual Perception, ( If you choose a perception of 6 and the four eyes trait it will be 5 even with glasses.) even with the glasses on you won't have the required perception to get certain perks, Sniper, Better critical unless you buy the perception implant. I have tested this extensively.

Skills:
Note: These stats are based on the corresponding skill starting at 20, these numbers may vary depending on which skills you choose to tag during character creation. the order in which they are arranged is based on the order in which you'll need to raise the appropriate skill to get the appropriate perk. And with an intelligence of 6 you should get 13 skill points each level this could change if you have some how raised your intelligence like getting the intelligence implant or reading skill books.

Note: The last 6 I personally like a High repair even that late into the game and I like my Medicine around 60 for the Nellis quests and helping at forelorn hope. Got to have everyone healthy before I slaughter them other wise it would be unsportsmanlike.

With a STR of 4 you won't be as good with rifles and such weapons that require 6+ STR. If you put CHR to 5 and STR to 5 you can buy two implants to get them both to 6. You could also take the weapon handling perk.

Enclave also used the plasma rifle, which is the plasma caster. So 8 strength would be needed to be able to use it.

Or 6 with weapon handling perk.

Energy Weapons has to be tagged if your gonna use an Enclave build but still I like the concept it should be a fun character to play.
