“Your brain is back in your body, but some of the advanced technologies remain: Your head still cannot be crippled, but you are only 10% more resistant to addiction now. Surprisingly your damage threshold has improved by 10% (minimum +1 DT)”— Fallout: New Vegas description
Big Brained is a special perk in the Fallout: New Vegas add-on, Old World Blues.
Location
Convince your brain to return to your body or convince it to come back to the Sink while you deal with the Think Tank and after the completion of the add-on, you have or you can have your brain reinserted into your body. This perk replaces Brainless.
Effects
Your head cannot be crippled, you gain +10% Damage Threshold (minimum +1) and +10% resistance to chem addictions.
Notes
- Compared to the Brainless perk, you gain an additional +5% Damage Threshold at the cost of -15% chem addiction resistance.
- The DT added by this perk and Brainless does not work correctly. See talk page. A fix for the PC version is available here, a fix is also included in the Mission Mojave bug fix compilation.
- Synergizes well with the perk Chem Resistant and Old World Gourmet
for 66.25% chem addiction resistance. - However, it synergizes poorly with Eye for Eye, as it reduces the total number of limbs that can be crippled.
- Big Brained shares the same Vault boy image as Brainless.
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 Implants, Reinforced Spine, and this perk, it will lead to a naked DT of 14. ((3[2]+4+2+1) * 1.1 = 14) [verified]
