Technology guide question


Rules Questions


I recently picked up the Technology Guide, and one thing I'm looking to do is to create a cyborg pc. Now since everything in it seems to need to use power cells to function, is there anything that makes it so the cyborg powers it with his own bodily system, like eating, heartbeats, cerebral synapses, etc.? Thanks ahead of time.

Sovereign Court

Pretty sure the cybertech don't use any power cells, someone correct me if I'm wrong. The only problem it is very expensive.

Liberty's Edge

No power source is listed. In the game I am running with Iron Gods AP, I will be assuming a power cell will be included in the cost that has a lifespan that would be trivial compared to lifespan of the character. It may be something they errata later


I presumed that cybertech used the character that it's attached to as a power source.

That's what I'm thinking. Kinda along the same lines as the Matrix said about using humans as a power source. I'm looking to make the cyborg have inbuilt weapons, and since those have a limit on number of shots before being recharged, I'm thinking of using the rules in the system that say an inbuilt weapon doesn't use its own charge, but the energy of the host. I may adjudicate it as using the charge of the weapon, and the body slowly recharges the weapon, perhaps 1 charge per hour or some such. As the Technology Guide is still somewhat new, I'm hoping there will be some follow-up rules for it soon.

Oh and Eltacolibre, the cybertech doesn't use power cells, but weapons and some of the other items do. This is why my quandary of if they use the humans bio-energy. I'm working on making an artificer that slowly transforms his own body into a cyborg effectively making him immortal where he'll be part man, part machine, still human, without the weaknesses of being a construct.

The technology items are balanced in such a way that the need for charges is offset by their power and cost. So no, weapons, even implanted ones should not run on anything other then charges. If you want a gun in your arm that doesn't use charges, you'll have to use a non technology one.

The cybernetics on the other hand are balanced against the bodyslot related items that have already come out (tattoo's clockwork limbs, abyssal implants, etc) so they don't need charges.

Also they whole matrix thing of humans are effective batteries is complete b@#!!~~s. And the idea of a human body being able to power a energy blaster is hilarious at best.


I'm not sure what cybertech you're looking at, the only weapon one I could find was Implanted Weaponry and says "A single light melee weapon or one-handed firearm can be implanted in an arm or cybernetic arm." It's not a cybernetic weapon, it's a weapon you put inside of you. It even explicitly says that doing it to a cybernetic arm doesn't count against your implantation limit. That seems to imply that Implanted Weaponry is mostly just hollowing out a space, less so providing power. I mean, it can only "draw" light weapons or open a little hole for a ranged weapon to shoot out of. It can't handle one-handed weapons, it doesn't make bullets (or powder, or anything about a firearm). "Melee weapons extend or retract as a swift action. Ranged weapons fire through a port on the palm or back of the wrist. Either type of weapon has statistics identical to its normal form. " Really makes a point that they otherwise work normally, just jammed in your forearm.

To the best of my knowledge nothing except spells, generators, and batteries allow you to provide a "charge" when something requires a "charge". You can't cast lightning bolt on it, you can't hook a quickling up to a hamster wheel, you can't clap your hands and believe. Well, depends on how you cast spells I guess. If you want to get by on limited resources you want a Techslinger for "Covet Charge (Ex): At 1st level, a techslinger can spend 1 grit point to use 1 charge fewer than normal when firing a technological weapon (minimum 0), as long as the weapon has enough charges remaining to be fired at least once. This deed replaces deadeye." and "Charge Recycling (Ex): At 11th level, by spending 1 grit point, a techslinger can grant 1 temporary charge to a technological firearm, even if the firearm normally can no longer be recharged..."

Hmm, not really. The human body in fact runs on electrical impulses called synapses. Even muscle contractions run off of impulses. So yes, the body does indeed run on and produce electrical impulses. This is why when one gets electrocuted, their body goes rigid, every muscle in the body gets activated at the same time. With that in mind, it goes to reason that connecting the electrical items to the humans body, they do indeed get power from the body. That's logical and scientific reasoning. Now the book may not say the body does so, but it does say that a weapon connected to a power source uses that instead of its own. And since the body is a power source, that means by RAW, the body can power a weapon. The only thing is getting the interface for it. Hence, creating a cyborg as is my original question as well as how much of a charge it might create for said weapons. As for a human body generating power for an energy blast being hilarious? You do realize this is a fantasy game right?

Wasn't planning on using something as archaic as bullets and gunpowder. Technology, and energy weapons are the way to go which fits for a futuristic cyborg character. Once a cybernetic arm is implanted, the arm itself becomes the pc's arm. The arm itself is powered by the humans body, which sets the precedence of an electrically powered weapon working off of the implanted human. Just really looking for ideas really on adjudicating how much of a charge the body provides for weapons.


If you're asking for help adjudicating how much "charge" the body provides, the answer is none. Period. The cybernetic parts don't use a charge, therefore they aren't provided one. How they move and work is fluff we're rationalizing after the fact. All a cybernetic arm provides is a +5 CMD against disarm for a weapon held in that hand, it doesn't even let you punch without penalty (like the steampunk arm). The precedent on using inbuilt power sources is presumably taken from the bestiary part, where it also says that all of the robots have a generator inside of them. So unless your character implants a generator, the body doesn't provide power. Even if the body does provide some form of power to cybertech it doesn't provide enough power to be counted as one "charge".

If you want help rationalizing why, I seem to recall something about peak charge batteries (or something similar) which let you store a lot of power and release it all at once, but then required a lot of recharging to get back to that level. They were for lasers, so you could fire a strong laser blast but then had to wait for it to slowly charge. So everything that uses a charge uses that, but all the other stuff just uses normal, long-term batteries.

Now, so I'm not just raining on your parade, there may be an alternative (provided you can get the DM to agree to it). Treat the human body as a generator, one with zero charges. That would let you use the "exceed yield" option to draw power from your body, with a small chance of shutting down or exploding.

That's exactly what I'm looking for. The part about a generator implanted in the body sounds interesting, but since that means a robot would have to be destroyed first to get one, it leads one to wonder about their construction in the first place as the books don't have a DC for it.

I like that idea since it would be like power attack of an energy blast only used during an emergency.

A good question as a corollary, if a cyborg has a battery built in, and charges are electricity, could a lightning strike recharge the battery?

Incidentally, I think in regards to the body creating an electric charge for implants like arms and legs and such, it only has enough to power those items as it would normal arms or legs. Anything outside of its normal functions would need more power than what the body makes on its own. So yes, probably a built in generator. Maybe solar panels or something. Basically looking for ways a cyborg can power himself and anything attached to him, without the need of finding the rare generator. I tried looking at the android template, and it doesn't even have a generator, which makes one think it should power down without one. I dunno.

If your definition of logical scientific reasoning involves considering fantasy science, then yes. For one most of the bodies "electrical pulses" are electro-chemical, which is nowhere near the same as the power you would need for a device. secondly, I did say, efficient battery, so even if there are "electric" pulses in our bodies, that does not mean that we make any sort of usefull excess energy. And those are just the problems with what your saying I'm hopefully assuming are not going over your head.

Exactly why I figured that when a body has cybernetic arms/legs, the body can only power the natural functions of said items, and nothing above that. Basically a body simply doesn't produce a strong enough charge, so I'd need another way to keep something charged, like a sonic blaster or some such. That's why I'm wondering if getting shot by a lightning bolt would charge his systems. Seems logical, and indeed could have the adverse effect of an overcharge. Either that or building a generator into his body. So far I've not seen any write ups in the book on how to determine the installations of generators. Unless others have seen the Iron Gods Path books(which I've not), wondering if those have more information on generators.

In the case of lightning its not just a problem of overcharging, but also from the fact that lightning is a surge, not a current, so it wouldn't be able to recharge it.

a more potent resource to use in the human body is the ATP molecules or the human bodies heat, several resources could be removed from the blood and burned for electricity.

synapses don't "make" electricity, they create an imbalance in the charge between them and the next synapses over. if it was just electricity, the charge would be shot into the whole body and not the next synapses over. (it just sort of pulls the electrons all to one side)


So, in case you didn't notice from the Tech Guide, all generators are listed in the "artifacts" section. They're meant to be super rare so that outside of Numeria and the Technic League nobody has infinite power. You also can't move them. So we're breaking significant design choices by doing this.

"This" is at-will command word activated Recharge spell. It's 14,400 for the spell (bard list) and somewhere between 25,000 and 125,000 for the material component. I can't tell whether you're supposed to add the material component cost for each daily use, or just once if it's a daily use item. This will let you generate 4 charges for a battery (with a 20% chance of exploding the battery, same as generators) or 2 charges to any tech item (no chance of explosion unless it's timeworn).

I suppose I could always have the character craft solar panels to attach to his body reminiscent of Wall-E lol. Or craft an item that has a continuous recharge spell on it, since it does say one can craft items with a spell as a mechanical term instead of being an actual spell. In any event, generators are also inside robot bodies, so could always find a robot, break it open and take the generator lol.

recharging batteries, regardless of the source, have a 20% chance of making them explode.

That's why you ignore the battery and recharge the item itself. No explosion chance then.

I think that's the route I'm going to take. Craft solar panels to extend during the day, similar to how a caster prepares spells, only I'll require a light source. At least until the PC encounters a robot for pillage lol

Think of it this way... radios and laptops both have batteries. What generally happens to either if they're struck by lightning?

or this

(a engine that runs on heat, even as little as human heat, that can be used to create electricity, like any motor that creates torque)

Or a machine that generates energy simply due to the body that moves. Lots of tech today that does so(which was part of my original idea of the human body producing it). I think you just gave me the best idea, thanks a million :) Looking at the generators in the books, a human generating energy would probably be far less than the ones presented in the book but still enough to work for what I'm aiming for. Just need to figure out a mechanic for how much. Turning him into a lightning rod is another idea that would make him absorb lightning. Once I have it all compiled, I'll post the build for others to look at for tweaks. Hoping to make him into a combination of Tony Stark(Iron Man) and Cyborg(DC comics).

THE SAME THING THAT HAPPENS TO EVERYTHING ELSE!

Gods I love that line!

I would start a new thread in the Advice Forum.

That's where you can get advice on your build.

Good idea, I'll just link this thread in it so it is known how the idea started.
