Re: GURPS Ultra-Tech: Square Root of Destruction
That's something I noticed, especially in regards to the vehicle-mounted versions like the Semi-Portable and Gatling lasers. The TL9 Semi-Portable has RoF 10, and the TL10 Gatling (same weight, double the cost) has just RoF 4. If the RoF is arbitrary, I may just change all of the mounted lasers to RoF 10, perhaps with "recommended fire-rates" based on available power supply (for instance, running from a vehicle's power plant). That would certainly help the Point-Defense laser live up to its name.

And I found that including the power cell worked better... though now that I look at it, the dinosaur laser doesn't include the power cell in its measurement (its a p). Perhaps I should revisit that (10x is still off, though). EDIT: You're right, without the cell works better (which explains why my smaller weapons were more off than my larger weapons, since the larger weapons don't include the cell in their weight). Adjust TL 11 Plasma/Fusion to 7.5, and things tighten up nicely. Quote:
The rest totally fits my observations, though, particularly RoF.

So, you take the cube root of 19, getting 2.67, and multiply that by 10. This gets you 26.7 damage, which is approximately 8d-1. Round, and you're done. The actual regression gives you 10.5 times the cube root of weapon weight minus 0.2 damage, but that's close enough to 10*CubeRoot(Weight), after rounding. Quote:
Laser weapon output is ( 3 * Damage^3 ) Joules. For example, an 8d dinosaur laser outputs approximately 7.3 kilojoules, while a 4d laser outputs 1 kJ, and a 6d laser outputs 3 kJ. A C cell holds 28 kJ total, a D cell 280 kJ, and a B cell 2.8 kJ. Some weapons don't match these numbers for some reason unknown to me - possibly errors in the weapon tables. |

Note that a C cell doesn't actually hold exactly 28 kJ of power - it can provide 28 kJ of laser output, which will probably cost about 50 or 60 kJ of electrical input. This is because lasers aren't 100% efficient in conversion of electrical energy to laser energy. |

AA: 28 J A: 280 J B: 2.8 kJ C: 28 kJ D: 280 kJ E: 2.8 MJ F: 28 MJ This is, again, in laser output power. Actual energy content is probably something more like: AA: 50 J A: 500 J B: 5 kJ C: 50 kJ D: 500 kJ E: 5 MJ F: 50 MJ E and F cells have significantly higher energy densities than smaller cells, for reasons that were never clear to me (this is something that's part of the core of Ultra-Tech). |

Has anyone tried tackling beam weapons that cause afflictions instead of damage?
