Currently the only craft system implemented on 3 towns allows you to make ammunition or thrown weapons To do so you need 1 each of 3 types of item. 1. controls the weapon type (fletchers equipment for arrows, bullet mold for sling bullets etc.) these are all from the lvl 1 archer merchant. 2. Type item, start with a Basic ammunition maker (merchant 1) , this controls the damage type. 3. A power item there are 7 of these the first of which is the Standard ammunition maker use 1 each of these items. Notice in the combat window that it tells you which ones you have set each time you activate one. Crafting won't work unless each line of these has an item listed. Then activate the craft menu radial 1 (9 O'clock) then 5 (12 O'clock). This starts a conversation choose craft ammunition or throwing weapon. you are then offered the option of crafting the item along with the cost and the DC. Success generates the item and takes gold. failure takes half the gold cost Success by >20 will reduce the gold cost. very high skill will reduce the cost to 1/15th of base so it is worth experimenting with cheaper ammo for normal use and keeping the best you can make for special occasions
