If it truly is weightless, but still occupies a certain volume, than it is lighter than the air it displaces and therefore buoyant.
It could also be pretty useful in shipbuilding, I suppose, or high-rising structures to reduce the weight placed upon the foundation, but you'd have to worry about your girders and bolts floating away when you're building it in the first place.
>>45284507 Wieghtless, as in hovers in the air wherever you put it? Or weightless like Cavorite is?
In the first case, unless something is made entirely of it it'll have some weight and sink (very slowly). But it would reduce the overall density, so useful for build boats and stuff. Basically, they've discovered naturally occurring Aerogel.
In the second case, how the hell does it exist on the planet to begin with? In the same way as heavy metals gather at the Earth's core, surely all the Cavorite has flown off into the depths of space.
>>45284690 My immediate assumption would be that this shows the world didn't form in the same way that Earth did in our universe. Which, y'know, isn't surprising, since most worlds with dwarves of the fantasy kind have gods and suchlike to do that sort of thing. They probably just put the antigravitium where they wanted it and left it at that.

>>45284690 >In the second case, how the hell does it exist on the planet to begin with? One must assume that it originated some time after the surrounding rock had formed, probably as the result of some sort of enormous magical catastrophe in the distant past. Which would also explain how a material that shits on the laws of physics could exist in the first place.

Nah. A metal with extremely high tensile strength and hardness but extremely low density (much lighter than air) is a much cooler idea.
You could make gigantic anime swords with it. Or just normal-sized swords that develop a new fighting style due to them being so easy to move around. Maybe they put a core of steel in so that its exactly as dense as air and thus you can just leave it floating in the air if you let go of it.
It gets stuck to whatever wall the planet is rotating with, when brought to the surface will either fly into the sky or stick to the ground until it eventually flies into the sky based on the time of day.
If the shit is weightless it gets to ignore all gravity and thus only the movement of the planet and actual collision with other material will keep it under control.
>>45287723 That seems odd. You'd have to consider that anything beyond small scale metalworking is pretty much impossible, and that would change the battlefield fundamentally. It would look like a goddamn Aztec war.

>>45296487 I may be wrong here, but I do believe the weight of the arrowhead factors into the penetration power against armored targets. The obvious advantage would be that it, theoretically, would have unlimited range due to it never decreasing in altitude, but friction would still apply, so that attribute isn't quite as great as one might think. We don't know anything else about the metal in question though. What's its cutting edge properties like? Melting point? Is it soft like gold?
The dwarves begin trying to see its effect when added to liquor. Because dwarf. Alternatively, they'd probably make some super-lightweight projectile. Maybe bullets or crossbow bolts, or perhaps even javelins.
Additonally, I cannot into physics, so that's a thing.
