Hello!
I just started a game of DF:2012 after a 3-year leave. I thought it would be fun to start near a volcano instead of burning millions of trees for fuel! But... my primary layers are now igneous or metamorphic.
So, I have a couple questions.
1) How do I get dwarves to spar?
I've gone almost 2 years, and with (for the last year) 20 dwarves correctly designated to permanent military training and (half of one squad to) patrol, and I have NEVER seen anyone spar (though I did witness 3 accounts of people sparring when examining old logs; mostly it was animals fighting each other). I set up some archery targets (and set squads to train on them) a few months ago, and my marksdwarves don't use them. Everyone in my military will only do "individual training", "wait for training", "lead a demonstration", or "watch a demonstration". Nobody has gained more than 500-ish experience in any military skill during that time (but most have gained 100-300 exp in dodging, shield, armor, and mostly instructor or student). Most of my military has their primary skills listed as "Rusty". Granted, I can only give them wooden swords, axes, spears, crossbows, and shields, but sometimes even those skills are getting rusty.
Therefore - when I got attacked by a pack of monkeys, several of my soldiers lost hands, feet, or nerves (which might regrow?). A goblin thief with a silver dagger demolished one of my long-trained dwarves. Note that they're somewhat buff, as I have them operate pumps exclusively when they choose not to be on military duty.
The wiki says to organize them in groups of 3 and then maybe they might spar. Another wiki entry says to organize them in groups of 2 with the same weapon. I mean, if there is a recipe that works, that's fine, but... has anyone here actually gotten their dwarves to spar more than 1% of the time? Is there some trick, like making a 1x2 barracks for each squad of 2 dwarves who have identical equipment?
2) I started in a volcanic zone, thinking free fuel would be neat! So I have a volcano. And igneous rock. And I made sure there was flux stone so I got.... marble (which is of course metamorphic). And a little bit of sedimentary... rock salt? When I look in the wiki, it says rock salt is sedimentary, and also that sedimentary layers contain metal, but I have yet to encounter any. Rock salt is the ONLY sedimentary stone I have. Can it contain (military) metal, or should I restart? The site finder said there was metal, but I have no idea what kind that is. I found a small deposit of tetrahedrite in silt, which is not particularly useful. Can non-sedimentary layers contain iron? Without a functional military, I have no chance of collecting enough goblinite to do anything useful, which I can only collect using wooden weapons and cage/stone traps (no sand on site).
3) Furthermore... is it even useful to play this version - if military training is utterly ineffective - or should I just revert to an earlier one? And if so, which one? Ultimately, I want to have a military that can do things other than lose their limbs and work pumps. I know it was possible in 40d.
