Lead Belly (Fallout 4)

Lead Belly is a perk in Fallout 4.

Effects
At rank one and two of this perk, the non-linear Radiation Resistance function is applied to ingested food and drink, and reduces the rads received. For example, rank one grants 10 Radiation Resistance, and would reduce the rads in an item that normally delivers 10 rads, by half, to 5 rads. Rank two would reduce the rads in an item that normally delivers 20 rads, by half, to 10 rads. The reduced rad effect of consuming the food or drink item is shown in the Pip-Boy, rounded to the nearest whole number. The third level of the perk simply eliminates any rads from any ingested item, no rads are shown in the Pip-Boy.

Bugs
The radiation resistance provided by the first two ranks of this perk is added to the radiation resistance displayed in the Pip-Boy. This is incorrect (and can be misleading), as this specific radiation resistance is only applied to ingested items, and has no effect in resisting environmental radiation or radiation from weapons.
