The radiation of the wasteland has changed you! One of your traits has mutated into something else...— In-game description

Mutate! is a perk in Fallout, Fallout 2 and Fallout Tactics.


The perk allows swapping one trait for another.


In the unpatched Fallout, Gifted could be swapped for another trait while the +1 to modifier to attributes from it remained.
