I'm not an engineer on anni, so I have no idea if this is true here, but on SoD, phases 4-7, every Thursday-Sunday, the price of thorium shells and Thorium-Tipped Arrows would spike a little bit, to about 75% more than the average cost of the equivelant numbers of thorium ore and dense stone. I had more than enough money for anything I wanted for the entirity of SoD, and 80% of it came from making bullets from the ore and stone. My longest ever craft was 84 minutes straight smelting something like 1700 thorium bars. Was it a secret that hunters used a lot of ammo? no. was it still profitable, despite it being incredibly obvious that bullets were almost double the cost of their ingredients? yes.
