Crafting for Gil in FFXIV
When you turn in local leves, you will get a small reward and a new recipe which is then kept in your recipe bank. You do not need to study a recipe from leves to craft it.
When you accomplish any type Regional leve, you can get faction points. Each leve, according to level, pays out faction points, with higher level leves paying out more.
The easiest way for lower-level crafters to make gil is to make up vendors who craft components and then list them up at a high mark-up. You only need to spend 100 gil a piece to make leather straps whist other players will see the 2k cost you are charging as little investment when they are making a synthesis that is worth 200k when done.
