- Vault Brain Loses It
EDIT: Continues in Part 2!Ant Queen Pheromones
are an item in Fallout 3 that temporarily raise the users charisma by 3, but also temporarily lowers their intelligence and perception by 3 each. It's worth noting that this is on a scale of 1 to 10 with 5 being the average.
When I first encountered this item, it seemed odd to me that losing intellect and perceptiveness would make someone a smoother talker. My interpretation was that it temporarily rendered the user a sexy idiot, which still seems problematic given differing genders and sexual orientations, but whatever. Combine that line of thinking with Vault Brain, and here we are.
