Hard to Hard
Jonno Tin and Jenny Fer have made billions at it.
First of all, as a Armorer you will be doing a crafting profession. Previously a permit was required for this profession and you were unable to use a gathering profession; however that is no longer the case.
The Armorer makes breastplates, epaulettes and shields. He will need to get metals from the Miners or certain resources from the Trapper.
Once you have gathered all these ingredients, you will need to go to the nearest Armory to create you items using one of the machines available.
Armorers use an Armor workshop to craft their recipes.
