adamantium bow is awesome as a random starting thing. pity the material does not affect the bow shooting damage, only the damage when you hit things with it in melee.
also, have you got a thread in the mod forum or do you have your new files up on the file depo? ive never played anything but vanilla DF and this sounds like a mod that is interesting and not too world changing.
and whenever the properties of adamantium come up there is bound to be heated discussion. seeing as all we know about it is its a light blue, its mined as an ore, strands are extracted, the strands can be woven into cloth, it is 5 times stronger then iron, it is smelted into wafers rather then bars for use, its melting temperature is stupidly high, and it comes from the word adamant, whose root meaning is unbreakable.
i allways imagined it starts in a form somewhat like asbestos, which occurs naturally as fibers in the ground, has a stupidly high melting point, and can be woven into cloth. the romans used to impress guests by taking their asbestos tablecloth and throwing it into the fireplace to clean it, and they would wrap the bodies of their emporers in it before cremating them, to make certain that they could seperate the emperors ashes from whatever they used to burn him. its sortof a parralel, as adamantium clothing survives when dwarves are set on fire or fall into magma.
wonder if this means dwarves who work with it would end up with lungfulls of adamantium fibres like our real world asbestos workers. hmmm. more precious then gold or platunum, super strong, and oh so deadly to its crafters.
