Rad Resistance/Fallout 4

Rad Resistance is a perk in Fallout 4.

Effect

 * Rank 1: +10 radiation resistance
 * Rank 2: +20 radiation resistance
 * Rank 3: +30 radiation resistance
 * Rank 4: +40 radiation resistance

Actually useful, due to the way radiation reduces the maximum health and the availability of perk slots. However, it's more comfortable to avoid irradiation in the first place.
