hardness nodes

[hazzor]

Just wondering if anyone knows this.

Does wall hardness carry through layers or are they completely independent of one another, we have a very hard mine near our base and a soft one further away, wondering which one we should deepen.

Ive noticed that It changes with the stone type. In my mine hole at least, I can mine the coal very quickly. I can mine the schist slowly, and I cant even scratch the dolomite. All three stone types are within a few tiles of each other, making me believe that each stone type that spawned got a different hardness value. therefor I would say that the stone on level two would be random, and you should dig down what ever one would be more convenient to you.

EDIT: For clarity, I do not mean all schist is soft or all dolomite is hard. Im saying each node of stone/ore spawns with a random (or nearly random) hardness value

This doesn't necessarily prove anything but our L2 is less hard than our L1, so I don't *think* it propagates through layers.
I think Jorb has stated that different stone has different base hardness, modified by random fields.

I also made a minehole in an area that was significantly softer below than it was directly above, so I think the hardness spread of each layer is probably independent of those above and below it.

You might want to actually prospect inside your caves to see what's below too, since that could help settle your near/far location choice.

you can actually see the cave from the minehole and vice versa, it's just that to go to the cave requires 2 teleports, so it doesn't make much difference locationally.

It's definitely correct that hardness changes between types of rock. I went down there (I have less than half the STR of our miner) and everything was too hard to mine except for the coal which is super fast.

jorb said that hardness occurs in nodes, but each stone has a hardness modifier value, so yes, some stone is harder than other stone. one stone may be a hardness of 0.90, another 1.25, so if you have a node with a base hardness of 100, the two stones would be 90 and 125 respectively. (Note, I'd have to dig up the post on this, and it's been a while, so not sure I could find it quickly.)

I'm not going to say two reports of significant hardness difference between two levels is enough to confirm nodes don't spread across levels, but they never did in the past and no reason to postulate they do now unless someone can bring evidence to prove it.
