Big Brained

Big Brained is a special perk $$

Obtaining
The Courier must convince the Brain Tank to unite the Courier's brain with their body or convince it to come back to The Sink. After that, one can have their brain reinserted into their body. This perk replaces Brainless.

Effects
Your head cannot be crippled, you gain +10% Damage Threshold (minimum +1) and +10% resistance to chem addictions.

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%.
