You can craft items on amia? I have some crafting things, but they've never seemed to do anything, any help please.

You can craft certain items with the job system (look at the different job pages), you can craft traps (pretty straightforward), Harper Scout items (would have to ask a HS or a DM), and equipment using the Mythal system (Mythal page).

If you find yourself a mythal you can go to a mythal forge and attempt to infuse it with an item, as per the rules on:
