Khaine, are you planning to add weapon/tool mods unique to your mod ? I think it would be nice since you can put more mods to your weapon/tool in DF. In my last savegame i was having a hard time finding more mods for my crossbow, speaking of which i would really love for archery to get more love and viability. Even with titanium arrows i think it doesn't shine with one perk to spend on it while viable other weapons are nice even if it is not in the masteries they still hold on.
If giving archery some love interests you, may i suggest to look at Brazmock Archery mod, with this mod in vanilla i felt powerful enough in end game even if i am still just an archer. I never felt it with your end game archery.
