Mutate!

Mutate! is a Fallout, Fallout 2 and Fallout Tactics Perk.
 * Requirements: Level 9
 * Ranks: 1
 * Benefit: The radiation of the wasteland has changed you! One of your Traits has mutated into something else...
 * Notes:
 * If you chose only one Perk when creating the character, you can only exchange it for a new one. You cannot fill the empty slot.
 * In unpatched Fallout 1, you could exchange Gifted for another Trait and still keep the Character Points.
