now just wondering, does that mean that I have to get the obvious full arm x2 and obvious full leg x2, torso x1 and head x1 for a full body ? Or just obvious full farm x1 and that covers both arms ?
you would have to buy 2 obvious arms + 2 obvious legs +1 torso +1 head to be completely cyber.
just remember that stand cyberlimbs had an AGI/STR/BOD of 3 so to get those up to your natural stats you have to get the customized which will increase your cost by 30,000 per part.
30,000 x 5 (2 arms, 2 legs, torso, head) = 150,000 + the cost of the original limbs/replacements.
this may be pointless, as the op said the game has already happened and it was a one off, but RAW to use the customized cyberlimbs to raise the limb's stats you add 1 to the availability for each point. Meaning you add a total of 8 Body, Str, and Agi to the limb, combined, before you push the availability over 12 and need a Restricted Gear quality to buy it. Thats the trouble with cybertrolls, their natural stats are so high it is really difficult to get the cybergear up to the same ratings. To match the stats listed by the OP each limb would have an availability of 14, which would require Restricted Gear X4, and RAW the most you can have to start with is 3. Thats before the cybertorso, which starts at availability 12 and with the full custom stats would be at 22R, unavailable even with the quality without special permission from the GM.
Also, essence costs on this are insane. Four limbs+torso are 5.5 essence as standard gear, good luck getting another initiative pass after that, and the cost for alphaware on the the same setup is out of reach of starting characters.
I think the best way to build a "tank' character is one cyberlimb with a restricted gear quality to max out armor, a skin mod like dermal plating, dermal sheath, or orthoskin, a bone lace mod of choice, and a naturally high body stat. Combine that with high end worn armor are you are really, really tanky and can do it out of the box with a 400 bp character and still have an extra initiative pass.
