Continuing my quest to destroy the world, I have discovered a way to mine out ALL the slade in Hell, including revealed walls, except for the unminable "rind" around the map's edge. Combining this technique with
Dwarven power mining, it is now possible to flatten Hell and drop the rest of the map on top of it, removing virtually all evidence that Hell ever existed.
That's a project that will have to wait, however. For now, I have created a smaller demonstration project: the Hell Hole.
Artifact and slade furniture. One statue is of tick monsters (a type of demon), and the other is of Ezum Anvilage the Helmed Squid of Denominations, the militia commander who oversaw the conquest of Hell.
How it worksThe basic idea is to carve fortifications into the slade, then cast obsidian over those fortifications. The obsidian "overwrites" the slade, so you can fully mine out the tile. I came up with two different techniques for doing this. The first technique makes it easier to collect the slade boulders, but the second requires much less micromanagement.
Method 1This is the first approach I tried, based on the slade mining technique mentioned in my other
recent thread:
- Build a retaining wall around the area you wish to mine out.
- Construct a down stair over some unrevealed slade.
- Dig an up stair directly below it.
- Repeat steps 1 and 2, creating grid pattern over the area you want to mine. No, you can't build all the stairs first, then dig all the up stairs at once. Yes, this is really tedious.
- Carve fortifications in all revealed slade walls.
- Dig down stairs (or channels) directly above all carved fortifications.
- Add magma. It should fill up the fortification level.
- Add water. Thanks to the stairs you dug, the water can fall through the stairs into the fortifications and cast obsidian there.
- Dig out the obsidian.
Method 2This technique is a lot less tedious to designate than the other one. Instead of constructing stairs one by one, you dig ramps directly below the surface, then construct stairs in the holes created. The slade boulders will fall into the revealed walls below these holes, but they can be recovered if you mine out the lower layer, too. If you're already on the bottom layer of the map, the slade boulders will fall into the void, and they will be lost forever.
- Dig ramps directly below the surface. Due to slade's weird behavior, the floor above will be left intact, and there will be no floor at all in the level below.
- Construct or dig down stairs above the holes.
- Construct up stairs inside the holes
- Proceed as in method 1--carve fortifications, dig down stairs above, cast obsidian
