These are the rules of the Cave Challenge as they were explained to me. Many of you may have tried this on your own, but perhaps with different "rules". The goal is simple, survive in the caverns, and only in the caverns:
One - The fortress must be set up in the cave or the immediate walls of the cave. As much of the fortress as possible should be in the actual cave.
Two - Immediately upon embarking, you must head for the caves.
Three - No resources the surface may be used in any way. No water, wood, animals, or plants.
Four - No embark items from the surface may be taken: Fungiwood instead of Maple, Giant Mole Dog meat instead of Mountain Goat meat, etc.
Five - All 3 caverns may be used, but not the magma sea.
Six - Stone that is in no way near the caves may not be used.
Seven - No trading with the surface is allowed at all: the cave must be completely self sufficient. But migrants are allowed in.
Eight - The caves may be "tamed" only as is nessecary: you must preserve the natural asthetics of the cave. If you were on the surface and a sissy, you'd know how elves feel: except instead of not cutting down trees, you're going to be not building giant death traps everywhere to kill everything.
The dificulty (and therefore, fun) of this challege is setting up in a hostile enviornment without caravan support, and possibly without water/magma. If you find a magma tube in a cavern, you are very, very lucky. If not, well, you don't NEED metal.
If you try it, post the results.
Here are my experiences, should you care:
I'm on my thrid attempt at this: The first atempt was ended nearly immediately by an Ant Man Civ: three shields and a spear? Can I hire these guys as mercs?
The sceond was very well set up, but a Giant Cave Crocodile got in and killed everything.
My thrid is doing well: I bypassed the 1st cavern layer, and I'm in the 2nd. It has water AND magma!
Here are some tips:
- The caverns are usually metamorphic, which means that both sedimentary Coal and ingeous Obsidian will be dificult to find. Your best bet for an army is Bone & Leather aroured Marksdwarves.
- If you want trees for fuel, breach the 3rd cavern: it has the most variety.
- If you do get fuel, metal won't be hard to find: Lots of Hematite, Native Gold, and Garnierite will likely be running through the cavern.
- Nearly everything in the cavern will try to kill you, so you'll be wanting a good military set-up, and good doctors. I recomend bringing Obsidian for Swordsdwarves in case you don't find any.
- Wall up the stairway leading to the surface to keep out ambushers. You won't have to worry about Goblins at all. This is the only instance that "avoid the surface" makes your game easier.
- Forgotten Beasts can be killers, so make sure you have a "backup plan": perhaps a second, smaller outpost on another cavern level.
- Migrants can be repurposed as Engravers, Farmers, or Croc Fodder Hunters so you can save embark points for useful tasks.
- Bring extra picks in case you can't forge any.
Here's what I embarked with:
2 Adequate Doctors (Adequate Diagnosing, Surgery, Wound Treatment, etc.)
2 Competent Miners
3 Swordsdwarves (Competent Sword, Novice Fighter, Novice Shield User)
Here's the template for my two non-metalic military squad templates (all of this is worn over Cave Spider Silk clothing, except the boots):
Fortress Guard:
Obsidian Sword
Black-Cap Shield
Elk-Bird Bone Helm, Gauntlets, Greaves, and Leggings
Elk-Bird Leather Shirt, Vest, Boots, Cloak, and Hood
Cavern Ranger:
Black-Cap Crossbow
Black-Cap Buckler
Elk-Bird Bone Bolts
Elk-Bird Leather Quiver
Elk-Bird Leather Leggings, Shirt, Cloak, Boots, Gloves, and Hood
Now, of course, I simply put "Elk-Bird" and "Black-Cap" because they're my favorite. It doesn't matter.
Because Iron/Steel is hard to get, having quality weapon/armor makes is important.
And, as always, remember: losing is fun!
