| 1c | Salt Ponds | None | Salt | 30s | 2t |
| 1d | Charcoal Burner | Trees in Radius | Charcoal | 30s | 2t |
| 2a | Furnace | Iron Ore, Charcoal | Iron Ingots | 60s | 1t |
| 2b | Tannery | Pigs, Salt | Leather | 60s | 1t |
| 3a | Sandal Maker | Leather | Sandals | 120s | 0.5t |
| 3b | Weaponsmith | Iron Ingots, Charcoal | Weapons | 90s | 0.66t |
| 3c | Armourer | Iron Ingots, Leather, Charcoal | Armour | 90s | 0.66t |

```

## Output Summary

- Sandals: 1t/min
- Weapons: ~1.32t/min
- Armour: ~0.66t/min

## Bottlenecks

- Mountain Slot availability for Iron Mine
- Charcoal production (ensure adequate forest coverage)
- Leather distribution between Sandal Makers and Armourer

## Notes

This chain supports military expansion and citizen needs (Sandals). Not perfectly efficient but very close, allowing slight overflow for stockpiling.
