Pure Adamantine Weapons

[Belgerod]

The book states that pure adamantine is extremely expensive, so it is 'always' made into an alloy. However, I can off-hand think of two examples of modules that use pure adamantine as a building material. Therefore, I'd like to examine the effect of making a weapon out of pure adamantine.

At the simplest level, I suspect it would work exactly as an alloyed adamantine weapon, however the amount of hardness ignored by it would go from 30 to 50. This is because the alloy weapon ignores 30, which is equivalent to it's hardness, so the pure weapon would ignore the same amount of hardness it possesses (50). Also the hardness of the weapon would go up as well. Naturally, I'm open to additional interpretations or opinions.

I'd also like to speculate how much it would cost. Any ideas?

He is looking at Starfinder rules. Adamantine alloy is an actual thing there and has different stats than Adamantine does in Pathfiner. I think they raised the toughness for all materials.

I've been giving this some thought. I compared alchemical silver weapons from pathfinder and starfinder. The price increased by 3x for ammunition to 3.33 for weapons. If you decide these numbers also apply for adamantine weapons, then you might be looking at about 150 for ammo and about 8000 for weapons. (I rounded for nice clean numbers).

That makes sense, and is pretty reasonable. I think the only issue is that pure adamantine weapons could cut through starship bulkheads, but so could lightsabers. I might use this. Thanks!
