Bionics and leg ST

[jackcelso]

In ultra tech when building bionics arms you can buy levels of arm ST and calculate the damage done with a punch.

When dealing with legs you can change move and jump distance, but you cant calculate the damage of a kick.

So the question: How i calculate the kick damage of cyber leg?

Or should i create a new advantage LEG ST the would cost a fraction of ST perhaps 3 points per ST for 2 legs and 2 points for 1 leg?

Please any opinion is welcome.

"Leg ST" could probably be treated as something like Arm ST (No Fine Manipulators -40%), which would indeed be [3] for 2 legs. It would arguably be [2] for 1 leg (-40% on [3] is [1.8], which rounds up to [2]). Arguably, while Arm ST increases BL for determining what you can lift with your arms but not for determining your Encumbrance level, Leg ST would be just the opposite - you can't lift more, but you have higher Encumbrance thresholds.

Of course, if all you want is damage, that's something like Striking ST (Single Attack -60%) [2/level], stating that the Single Attack is your kick.

Leg ST, only, would not help you lift better, so I think it's just Striking ST for the legs. And it should be fairly limited, as kicking has a lot to do with the spine and body core in terms of delivering a powerful kick.

It's leg strength that lets you carry large amounts of weight around, particularly in a pack or as armor or similar, so it would influence BL for purposes of Encumbrance. Stuff like deadlifts more directly make use of leg strength for actually lifting things as well. And while it is true that the core and other parts are important for the strength of a kick, the same is true for the strength of a punch (or a sword strike, spear thrust, etc) - indeed, those tend to make use of leg strength to some extent as well - but GURPS is comfortable with letting you just buy Arm ST, so Leg ST should be fine as well.

I built Leg ST for Uplifted rabbits a long time ago. Use Leg ST for Kicks, all uses of ST that primarily involve the legs (e.g. Jumping) and Encumbrance when calculating effective Move. [3] per level.

thanks everyone for the imputs !!!! It helped a lot!!!

You're very much ignoring the hips and lower back here.

Honestly... Leg ST is a weird one for 'encumbrance' in my mind. Frex I think it should directly affect Encumbrance for purposes of combat speed while walking/running/sprinting and long distance speed for bicycling, but for purposes of determining FP loss to marches, post-combat, Encumbrance penalties to skills, etc, then no, it shouldn't affect it all.

Given the effects, Arm ST must include a fair amount of shoulder and upper back strengthening as well. I think it's reasonable that stronger hips and lower back are included in a hypothetical Leg ST advantage.

On the other hand, stronger hips and lower back (and, for that matter, legs) are going to increase the force of a proper sword swing, as well.

When we're talking about bionics, I think you have to ask how much additional power the spine and hips can bear. And for that matter I don't think you can have +100 ST bionic legs and walk around carrying cars.

Sounds like unsupported ST limitation from biotech. But it's for smaller differences
