OK, last new topic for this week... I promise.
How much does a modular cyberlimb cost Essence wise? I can't figure this out.
Does it cost Essence for the connector and then more Essence for the cyberlimb that connects?
Hand: You can install a modular hand directly, which results in a loss of 1 capacity in the hand, but no additional essence cost.
You can also install a modular connector in your wrist, which lets you mount a cyberhand directly; this costs 2,000 nuyen and 0.1 essence. Alternatively you can also install the modular connector in an existing cyberlimb, which allows you to essentially remove that limb's hand at the wrist and have a mount for a new one instead (5 capacity).
Partial(Lower) Arm: You can install a modular partial arm directly, which means it can be swapped out just below the elbow for another modular limb (just like the hand), but buying it this way takes up 2 capacity in the lower arm (but again, not a higher essence cost).
Or you can buy a modular connector for your elbow, which lets you mount a lower arm directly; 4k nuyen and .2 essence. Or install that in an existing full arm, which costs 10 capacity, again most of that is probably representative of it removing that portion of the arm (an obvious lower arm, for example has 10 capacity).
Full Arm: Again, you can buy it as originally modular, meaning it disconnects at or just below the shoulder, but you lose 3 capacity from the overall limb (essence cost still same).
Of you can install a modular connector in the shoulder (0.3 essence, 6k nuyen). This option doesn't have a capacity option because there isn't a limb to install it in.
