Firstly, I would just like to say that I am having HEAPS of fun with your mod.
Secondly:
2 questions.
1) Do Orcs, Snakemen, or Nords siege? Snakemen were automatically hostile, but I think they are on kobold level with invasions (no sieges yet). I slaughtered the Orcs and Nords caravans, but they have done NOTHING, they haven't ambushed or laid siege to me yet, and have not continued trading with me.
2) My archers (marksdwarves) will not not use stone arrows, I have literally thousands (3330 exactly) of "rocktip bolts", but they will not use them.
Suggestion: Adding rock war hammers and maces would be awesome, and be far more effective than rock swords, spears or pick.
-EDIT-
An updated manual with the new metals would be great--whats moon silver? where does it fit in terms of strength?
Although the Genesis wiki is outdated in a lot of ways, someone has been kind enough to edit material properties (they seem recent enough)
By compressive yield/fracture:
Copper -> Cobalt -> Spellwood -> Black Bronze -> Bismuth Bronze -> Bronze -> Iron -> Sun Gold/Moon Silver -> Steel -> Black Steel -> Red Steel -> Mithril -> Adamantine
By weight/density:
Adamantine -> Mithril -> Moon Silver -> Iron -> Spellwood -> Sun Gold -> Steel -> Black Steel -> Red Steel -> Bismuth Bronze -> Bronze -> Cobalt -> Copper -> Black Bronze
By edge:
Spellwood -> Copper -> Cobalt -> Iron -> Bismuth bronze -> Black bronze -> Bronze -> Sun gold -> Steel -> Black steel -> Moon Silver -> Red steel -> Mithril -> Adamantine
Hence, Moon Silver looks like a pretty good metal to make axes and swords out of, but worse than steel for armour.
--EDIT2--
No, wait. They have come to trade with me again... Time to test out my new Lets-Kill-ALL-The-Traders killamajig
