Crafting

A batch of n identical outputs requires (n-1)^2 completed crafts of that recipe. Quality q requires (q-1)^2 completed practices AND every consumed ingredient at quality q or higher. The lowest adequate stacks are used first, from your pack, the shared work pile and a storehouse you own or have permission to use in this room. Tools are reusable until their condition is exhausted. Workbench: 2 workers; kiln and smelter: 4 simultaneous charges; forge: 1 worker. Structural levels multiply capacity. Furnace batches use free slots in waves; workbench and forge batches process sequentially in one reserved place. All outputs and practice arrive at completion. Current jobs keep their captured timing. Text: craft ITEM [quality] [quantity].
