So, I have a question about how these are bought. The core rule book says that they only give a characteristic benefit if both legs are replaced, and that they most be purchased as a pair. The equipment section lists them as "Cybernetic LEG", not legs. Does this mean that each leg costs 10,000 credits, for a total of 20,000 credits to get the benefit? But the book says they MUST be purchased as a pair, implying the cost is for the pair.
Can someone explain this to me?
