In my current fortress (3 worldtiles large) i have magma, a good amount of lignite, lots and lots of magnetite, lots and lots of marble (basically, STEEL!!!), oh and a legendary weaponsmith early on. (second year or something)
So what i'm doing is making masterpiece steel weapons (not too many, wana have masterpiece armors too, and they ask for lots of more steel)
For every piece of masterpiece weapon i have a clone of no quality copper. (copper wich i need to import)
I currently have a masterpiece steel spear, mace and axe, all other weapontypes will follow when i trained some more dwarfs. (don't need it, yet)
In training are a axedwarf, (legendary in shield, great in armor i think, currently still in leathers though, high master wrestler and almost high master axedwarf, so still elite wrestler)
A speardwarf (still holding out of letting him become an elite)
A macedwarf (same as above)
2 marksdwarfs and one hunter marksdwarf wich took down an aligator and great eagle with bone bolts. (one of em is in constant training, he gets the artifact platinum/steel crossbow)
And a couple wrestlers to get shield/armor to a good enough level.
So yea, i like this plan, having one champion in each weapontype (a couple marksdwarfs though).
My fortress is capped at a 100 dwarfs though. (and i still need some traps on vital places for when ambushes strike, lethal because its such a small map wich basically has zero defenses still, only just end of second year now)
