Meteoric Iron Arrows

No it's for my game.

Because if it's for my game, we can assume that the shaft is a hollow cylinder, and the actual weight of an arrow remains the same.

It'll still effect cost then.

Uh, no. I have no idea what made you think that. Douglas Cole was entirely clear that it was acc 1 with the arrow.

Er, it isn't? Who said it was?

So my version of the arrow is $7 base, which is x7 the standard arrow price. That's a x7 multiplier relative to the standard arrow. I'd combine it with the Meteoric +19 CF modifier to give x140 price.

x4-5 weight, mine is closer to x4. I'd leave the +1/die damage. x1/3 or x/2 max range (again, my workup seems to perform a bit better, maybe because it's the regular bow instead of the longbow). No change to accuracy in my version, though -1 might be better if you're using Basic Set type bow stats.

Yeah, that's what I read it as too.

2>1, yes?

That makes sense.

Ah, that's true. The cinematic damage is still higher than the realistic damage, but the change in cinematic damage is lower.

Given how the math works, the damage modifiers differ as they do due to rounding breakpoints.

Base price for an arrow is x2, so 7 is x3.5

So would be CF +70

It does make me wonder if Shield or Armor works.

Can you unpack this? Do you mean -1 to the Bow's Acc? Do you mean -2 and -1 per die for damage? What's the effect on cost?

Except for the +19CF.

I don't have a cost factor in the spreadsheet; I assumed 'meteoric iron' had the same properties as my sheet assumes for TL5 steel, which is a lot like "Very Fine TL3 steel" based on how the old vehicles construction rules worked.

I mean: -1 to the bow's Acc when switching from regular to the heavier meteoric iron arrows, due to velocity reduction. +2 cinematic and +1 realistic damage per die, because the efficiency of the bow I built it around (a 78" yew longbow) nearly doubled from 45% to 80% due to the heavier arrow. And 1/3 the range, because the arrows are about 5x the weight of the GURPS standard arrow (0.1 lbs vs 0.5 lbs).

No, -1 to Acc, since my examples had the regular bow with Acc 2, and the bow firing meteoric arrows Acc 1.

No, it wasn't; I can easily make the design a hollow cylinder, though, which would leave all the stats unchanged.

Me; typo. I just transposed the numbers. Cinematic damage fell from 6.5 pts to 4.5 points, and realistic fell from 4.5 to 3.5 (more or less).

This is completely due to the higher efficiency of the heavier arrow, since the input energy is the same in both cases. Thus, higher delivered energy, more penetration . . . but 1/3 the range.

Compare it to the cost of Meteoric Iron Sling Bullet.
