Big Brained

Big Brained is a special perk .
==Obtaining==
This perk can be acquired by successfully convincing the Courier's brain to return to its body or return to the Sink and then going to the Think Tank to confront the Think Tank during Old World Blues. Afterward, if it was installed, the Sink Auto-Doc can optionally be used to restore the brain and swap out Brainless for the perk and vice versa.
==Effects==
Gaining this perk grants a permanent immunity to crippling for the player character's head, a 10% increase to Damage Threshold (minimum +1) and a 10% increase to addiction resistance when using chems.
==Notes==
* Compared to Brainless, the perk grants an additional +5% Damage Threshold at the cost of a 15% reduction in the degree of addiction resistance.
* The perk pairs well with Chem Resistant and Old World Gourmet for 66.25% chem addiction resistance.
* Although the perk seems as though it does not pair well with Eye for Eye, as it reduces the total number of limbs that can be crippled, the trade-off for losing a potential 10% damage bonus is eliminating the blurred-vision effect, which is a significantly greater detriment than the effects caused by other crippled limbs, which can be countered via speed-boosting perks or accuracy-enhancing chems.
* Big Brained and Brainless share the same Vault Boy image.
==Bugs==
* The description listed on this perk pertaining to Damage Threshold shown in the game is incorrect. The perk will add a permanent bonus of +1 to your DT no matter what, and then multiply that value by 1.1, rounded. For example, if your character has both ranks of Toughness, the Sub-Dermal Implant, Reinforced Spine, and this perk, it will lead to a naked DT of 14. ((3[2]+4+2+1) * 1.1 = 14) 
** Because of these errors in the maths for the Brain perks, especially when compounded with rounding, both perks may result in the same bonus even for high values (30+) of DT, causing this perk to be unequivocally inferior to Brainless.
* In addition to the bug mentioned above, you may never gain the rounded 10% if you are "naked" or wear body armor with 1-2 DT, any headwear is excluded. But if you're wearing body armor with 3 or more DT, you will actually lose the permanent +1 DT and only gain the 10%.
