Fallout 76 mutations

General information
Mutations are a type of condition in Fallout 76.

When the player character gets exposed to radiation, they have a 5% chance per 5hp radiated to be mutated. This can occur from being struck by excessive background radiation from an source such as zones devastated by nukes, irradiated creatures, radioactive waste etc., or by consuming radioactive food and liquids. A player can have multiple mutations at once.

RadAway has a chance to cure mutations, while any radiation protection gear (e.g. hazmat suit or gas mask) reduces the chance of mutation. The Starched Genes perk will also prevent mutation but will prevent RadAway from curing acquired mutations, essentially making them permanent while the perk card is equipped. Entering a contamination chamber will cure your radiation thus removing your latest acquired mutation.

Mutations are like traits from Fallout: New Vegas in that they have both positive and negative effects, such as the Strange in Numbers perk, which will increase the positive effect of a player character's mutation by 25% when their teammates are also mutated. The Class Freak perk can also reduce the negative(s) by up to 75%.
