Haha, well bone equipment is god damn awful
. I've already tried it few times and each time my militia was slaugtered by copper wielding goblins. There is a lot of stuff when considering quality and usefullness of the weapons and armor... but mostly I use bone armor only when no other things are available. It goes like this: bone - copper - bronze - silver - iron - steel - adamantum. Or something like that anyway
. I'm going from memory. Of course there is also question of quality, so artifact bone equipment can be awesome, but it's more of a exception from the rule
. Shells are pretty much on the same level as bone thingies.
Are there any bone weapons? Not counting artifact ones?

God, 300 dorfs? My computer would die and burn. With 200 it's getting like half of the normal FPS. And when siege/ambush comes... duh. I prefer to rely on lumberjacks to do the killing. The axes are edge weapons which means they cut stuff off. And that tends to kill people and monsters fast. Pickaxe is a piercing weapon, with some bashing capability I think (I remember reading it on the wiki) so it has a chance to destroy vital organs.
Bridges are good, but won't the river turn to ice in winter? I got fucked over by the temperature changes more than once
. And making different part of the fortress the military and civilian is cool and all... in theory. Because dorfs and animals love wandering here and there. Pissing my OCD off.
Also I must say that pit is not really THAT effective. Better thing could be probably some kind of magma chute for prisoners (but their stuff would be unrecoverable) or drowning chamber. It depends on the level of the skill though. I'm not sure I know enough to attempt it.
