Colony 6 reconstruction/Commerce Level 4

Commerce Level 4 is the fourth module in the Commerce category of Colony 6 reconstruction. The materials needed can be obtained from the Fallen Arm and Mechonis Field. Completing it opens a new shop.

Hint
''Now we've got shops along the main street. There are so many, I don't know where to start shopping! It's still not enough though. We'll need four more items. Just bring Piranhax Fishmeal and Silver Antol Fibres. I think you can get both in a place where there's a vast ocean. Try asking people in the colony about other items.''
