I am creating a character with a cybernetic arm, which needs repair (and therefore qualifies for Unhealing (Total)[-30]), but it seems unfair to have the character gain 30 points for what is only a problem with part of their body.
How does one point cost Unhealing (Total) on only part of a character's body?
GURPS Ultra-Tech p. 207 covers how to build cybernetic body parts. The short version is that you take the appropriate disadvantage (One Arm in this case) and then apply a Mitigator (B112) based on the limitations of the cybernetics
According to Sean Punch Unhealing by itself would be a -90% Mitigator. The usual combination for cybernetics given in Ultra-Tech is Unhealing, Electrical, and Monthly maintenance for -70%
Mitigator limitations are not subject to the -80% limitation cap since that's not exploitable the way it would be with advantages.
One Arm (Mitigator, Unhealing, -90%) [-2]
One Arm (Mitigator, Unhealing, Electrical, Monthly Maintenance, -70%) [-6]
The simplest way seems to be to base it on the rules for Damage Resistance with Partial coverage (pp B46-47). Damage Resistance on a single arm is bought at -40%.
However, we're limiting a disadvantage here. The easy way to do that is (-100-advantage limitation)%, which comes to -60%. So Unhealing (Total, 1 arm) would be -12 points.
