Trade Skills allow your character to harvest and produce resources and materials for crafting in New World MMORPG. There are 7 crafting-related skills associated with professions, 5 different refining skills, and 5 gathering skills. Leveling them up is essential if you want to focus on making different items.
You can see your current progress in each of them at your Character Menu.
Every trade Skill has a hard cap at 200. This means you can't level them up after you reach the cap. The good thing is that you don't need to focus on one or two of them. You can try to advance in all of them simultaneously if you wish. This will require more time but this is possible.
Crafting skills allows you to unlock new blueprints and to become more efficient in producing different stuff. Higher skill allows the player to produce items with higher gear scores more often.
Gathering skills allow you to harvest different types of nodes. They also allow players to track the nodes on the minimap. For example, you will be able to see the nearest Iron Nodes within a certain distance.
Refining skills allow players to produce different types of material using the resources. The deeper you advance the better materials you can make.
