But assault rifles do 3d, 4d, 5d, 6d, 7d of damage, pi, pi+ or p++ and that 10, 20 or even 30 times per second!
And all this on a range upto some thousand yards!
A Melee swing will always be less efficient.

Not even a ST 20, 3d+2 + Weapon Master = 3d+8 = 5d+1 who uses All-Out-Attack with 3 attacks per second (All-Out and Rapid Strike) can go so far!

The modifiers (like broadsword doing sw+1) would then also scale, as (say) +1/die.
I like this approach!

Do you say, that swing would be 2* thrust?
Or 1.5* thrust?

And the modifiers would would be multiplied as well:
sw+3 at ST 50 would be multiplied with 50/10 for a final 5d+15?!?

One problem i have is, that it is difficult to apply damages for ST between full tens. The more regular tables use the Xd-1, Xd, Xd+1, Xd+2, ... way to calculate this.

But this is just true for ST upto 27 anyway!
Why should it be different for greater ST?

Now, this is NOT about what works for you or me, of if i will ever use such ST in my games at all.

It is about the game system itself - call it a theroretical musing :)

Basically, from ST: 10 to ST: 27 swing is twice thrust, and thrust is roughly linear; up to ST: 10 the same is true, but with a different line, so it hits the origin; and above ST: 27, swing settles down to thrust+2d.
Great graphic, thanx!

Usually each weapon's net multiplier would be precalculated. I still think something like that is a more-accurate way to go.

For the "GURPS in quadrature" idea I've been working on(squaring all damage and DR, probably with a scaling constant, for reasons of realism), it may be convenient to use a calculation like the one for Basic Lift.
Very interesting stuff!
Did you publish about this somewhere?

I would like to read more :)

Point, but he shouldn't be able to do it at ALL. It's possible (unlikely, but possible) to punch though plate or mail armor in GURPS without really bending the rules that much. Toss in Weapon Master, and you can rapidly get to the regime where you'd rather attack guys in heavy armor with a stick or sword than a gun. that's just wrong.

Not sure. I'd playtest both and see where things rub the wrong way. The assumptions in GURPS seem to suggest that swing (2x damage) has about quadruple the energy of a thrust. that might be correct; 1.5x damage suggests about 2.25x energy; that also might be correct. Not sure.

Yes. At ST20, you swing for 3d and if your weapon is sw+3, you get 3d+9.

The best way to handle this type of scaling is likely to apply a certain fraction of the damage of each roll to the weapon itself, so that really strong people using weapons not built for that ST can and will break them. Regularly. I've broken fencing sabres by misuse this way; larger weapons are no different; all materials will fail if overstressed.

Take the decimal remainder, multiply by 3.5, drop fractions.

This will give (say) 2d, 2d+1, 2d+2, 2d+3, 3d. the nd-1 point is harder to figure, but it would come between 2d+2 and 2d+3.

I don't really see where you're coming from with this.. if you have a guy with Weapon Master, you're already saying that he's a cinematic character. Also, the player of that character most likely wants his character to attack guys with sticks or swords, rather than guns, and is paying the points for that (and has the GM's permission, given that he has the advantage). And another player with Gunslinger will have his own ways of breaking the rules, if he's so inclined.. or not, but that's a GM call, for a certain kind of setting.

In a stat-normalized realistic campaign - the problem doesn't exist. You won't have ST 20 weapon masters running around.

Well, in that case, he should also pay a lot fewer points for ST; I'm fond of 5/level for ST, 2/level for striking ST (yeah, the parts cost more than the full stat; I don't have a problem with that). I'm also somewhat fond of a model in the form of: Damage = ST*X; X is roughly 0.06 (thrust) or 0.1 (swing), +0.02 per +1 on the weapon. Thus, a ST 20 martial punch (thr+1) would do 0.08*20 or 1.6d or 1d+2. That might reduce Striking ST to *1.

Um, pretty much no. You have to get way into the superhuman level (and have enough DR to be functionally immune) for melee to be preferable to an assault rifle.

What I have in my proposal is basically ST*0.1 for thrust and ST*.15 for swing (or maybe ST*0.2); the first proposal is sw = +50% more than thrust.

Yours is basically the same, but down one step, with ST*0.06 and ST*0.1; still +50%. There's only a slight difference from my proposal and yours; playtesting would work it out. For recosting ST, well yes. I think i mentioned that; if not, I should have.

ST17 with a swung weapon is 3d-1. WM full version is +2/die. This is 3d+5, or 4d+1. Add in an axe or sword (+3 and +1, IIRC) and you're at 4d+4 and 4d+2, both are entirely within the "normal" non-superhuman budget and basically equivalent to penetration out of an M4 carbine.

And if you punch through DR, you've penetrated; we've tried to handwave this away and rationalize, including in the upcoming Low Tech rules, but there you go.

It's more egregious when you compare ST-based damage to pistols, of course, since 2d+2 for the 9mm is far more easily attained, but still, you are in a territory where "guns are better" starts to get a little squishy.

Of course, with the pistol or rifle, you get tens to hundreds of yards range, ten to thirty shots (100 with a C-mag), and RoF bonuses; for melee, you get to use full skill more often, though, since range penalties stack up quickly.

My point, which still holds, is that a dude swinging an axe rapidly gets to the point where he can really do things that are implausible with human ST alone.

Default Re: Rationale for the progression of ST-based damage

You know looking at the rules at Supers 120 for enormous weapons I think the benefit of swing damage is meant to be telescoped into the weapon damage bonuses. The bonus for using a swinging weapon increased more rapidly than for a thrusting weapon.

Specifically: "The swing damage bonus is also proportional to length. On the other hand, the thrust damage bonus is proportional to the square root of length; making a spear twice as long gives it twice the weight, which boosts its damage, but the doubled length by itself has no effect on thrust damage."

So that super using the Eiffel Tower as a club gets massively more damage than than his buddy that uses CN Tower like a spear.

Presumably at high ST the length of a human arm just isn't long enough to translate into that much extra force.

I specified assault rifle for a reason. Doing the same damage as a fully automatic ranged weapon with a hand weapon is not tempting.

At ranges where you can use the axe at all, the ranged weapon doesn't have a skill penalty.

Isn't the axe-guy doing things without human ST alone? Weapon Master?

I think a realistic ST 17 guy would not have Weapon Master, and be something like 600 lbs*.. he should dish out some serious damage with an an axe, but still is somewhat behind from 4d+4.

*If you follow the reasonable formula for living creature's weight from HP from Fantasy - very usable for realistic calculations, not so for usual PC's
