A robot’s core programming and memories are contained within its central processor– its “brain.” The brain’s drive to survive is measured by the force of its personality, as represented by the robot’s Charisma.

Whenever a robot is destroyed (reduced to 0 or fewer hit points), some brain degradation occurs. The robot’s drive to survive is measured by its Charisma, which is reduced by 1 whenever the robot’s body is destroyed. The brain ceases to function and the robot “dies” if its Charisma drops to 0.

As long as the robot has 1 point of Charisma left after its body is destroyed, its brain can be removed and transplanted into another robot body of the same size and frame. Removing and transplanting a robot brain takes ten minutes of work with an electronic tool kit and requires a successful Repair check. The DC of the Repair check depends on the robot’s frame, and not having a tool kit imposes a –4 penalty on the check.

A robot that gains a new body retains all of the memories, skills (or skill software), and feats (or feat software) of its previous “life.” It also retains any class levels and mental ability upgrades, but loses any physical upgrades, armor, sensors, accessories or other improvements and additions to the destroyed body.
