RAW per High-Tech treats a TL5 arm prosthetic as giving Ham Fisted 2 (One Arm for -40% discount).

Is it reasonable to treat this as giving only half penalties for actions that use both arms, with full penalty only applying if you're doing a one armed action with the prosthetic, or what's the intention here otherwise?

I'm building a Martial Arts Style list of techiniques/skills/do not remember the name used by the GURPS. It's supposed to be in a style similar to Demon Slayer (Kimetsu no Yaiba) and other Martial Arts Fantasy which have "Element X: Form 1 Attack!" (ex: "Water Style, 1st form: Raining Daggers!")

Let's use the following examples I'm looking for rules on How to build:

1. Powers which use 1 Weapon Damage/Level instead of the Innate Attack 1D/Level Damage. For instance, when using a Dagger this "Technique"/Power/Style. My initial thoughts were to cost It as "Extra Attack (-Once per turn acessibility limitation)"

2. Powers which you could chose to spend FP to increase It's Damage. For instance, a Technique that Deals 2D Damage at Level 2 but for each Level you've got you could spent as many FP as It's Level to add +1D each

Does It make Sense? I'm late night writing not in my main language, fueled by the last remains of cofee within me. Please feel free to ask any questions If I was not comprehenseable

Hello,

I just finished posting a short (because the bad guys blew up in turn 2) example of spaceship combat at https://thewabatuckian.wordpress.com/2026/07/31/gurps-tactical-space-combat-example/ .

If anyone reading this happens to be an expert, please check it out and let me know what I did wrong so I can fix it.

Thanks!

ps: I edited my post with the corrections you gave me, thanks again for the help!

Hi! So I am considering making a sort of devil character that would make deal with the devils contract where they give powers to others, for a price (insert evil laugh here)!

So how could I do something like that?

Hi! So in pathfinder living things are powered by positive energy and undead by negative energy. They are healed by their own energy and harmed by the other. So healing spells in pathfinder can potentially harm undead. And spells that heal undead can harm the living.

Any tips on how to convert this to gurps?

I'm coming back to GURPS after quite a few years. A few in our group have expressed interest in picking it up again/giving it a try for the first time.

This has also coincided with a rewatch of the 2003 classic Reign of Fire and the "castlepunk" tanks Vs dragons aesthetics immediately made me think of GURPS and led me to reread Yrth, it never hooked my in my youth but as I think is common my interest in history has drastically increased.

The concept I have is a besieged french town in WW2 (perhaps itself a weird parallel) gets Banestormed to Yrth allowing for a mix of soldiers, partisans and civilians along with significant but limited military tech (TL6- early 7) and I would structure the campaign into arcs of 2-6 sessions followed by a time skip allowing for multi generational development.

Obviously this would put the players at contention with many major forces within the world and their tech having potentially far reaching effects but I am less concerned about keeping the world's status quo stable than letting the players navigate the tinderbox.

I was wondering if folks had experience or advice running such a game or what other starting scenarios could work? (I'm definitely open to different starting points, the village just seems one of the easier ways to have such a mix of characters come through. My other idea is a decommissioned warship that has been converted into a museum.)

Do I get it right:

Let's say we have 2 tons of sludge in cargo, worth $1000

Factory adds 40% to the raw materials value, making, let's say, $10.000 per hour

To make a 2-ton, $1.000.000 vehicle from it, we need to increase the value of the sludge 21 times, and it'll take 100 hours of work (because $10.000 per hour), each next increase in value taking more time due to greater volume in $

It just makes sense in my opinion, especially if you use a house rule that Per and Will are separate from IQ
