I’ve only just begun to take a look at crafting in Tree of Savior and what I’ve found thus far is pretty minimal. It hardly seems to be a key aspect of the game yet it is a viable way to obtain better gear. If you’re looking for a deep and intricate crafting system, you’re not going to find it here, however if you like the idea of crafting one or two pieces every now and again as the culmination of several quest chain rewards, then you’ll be quite happy. Before going any further though, I want to clarify that this is not intended to be a definitive guide, this is just what I have discovered so far by naturally playing through the game without outside resources.
Recipes are required to craft items, and from what I’ve seen this is limited to gear and weapons. Everyone is able to craft these items and the materials are gained through questing and killing mobs, not farming nodes of any kind. So you won’t find a list of professions to chose from or have to limit yourself to one form of crafting over another because the entire system is pretty limited to begin with.
Other than the weapons and gear you can make, I’ve seen no other forms of crafting. If they exist, it must be something discovered later on in the game. There are several “crafting” classes like the Squire, Alchemist and the Pardoner however I wouldn’t call them crafters so much as “service” classes. If you happen to play a Swordsman, Wizard or Cleric respectively and select one of those three advanced classes you will be able to set up a shop in one of the cities to sell item repairs, improve gems, or even sell abilities. From what I understand you can have one character set up to sell these things in town while playing on another character on the same account. It’s a simple form of having player vendors but it’s more than what I’ve seen in most other MMOs.
As for the more “traditional” crafting in Tree of Savior, it seems limited to a handful of recipes that are obtained as quest rewards and as the occasional drop from random mobs. At first, most of the recipes you receive will be for blue quality or “uncommon” gear. You will have to collect several crafting ingredients as drops along with a base item, like a simple chest piece or gloves which can be received as quest rewards or random drops. Once you’ve collected everything you will need to have your character sit (I forget the default key as I remapped mine) and then press “2” to open the crafting window.
The menu will appear on the left hand side where you can select the item you wish to make. Selecting the item will expand the menu where you will then click on the boxes with plus signs to add each ingredient, name your piece if you would like, and then once you are ready press “craft” to make the item. You will need to have your materials in your bag as they will not be detected if they are in your storage. Thankfully Tree of Savior is very generous with the amount of crafting materials you can hold in your bag so it’s not too difficult to hold on to everything you need to make several items.
Recipes rewarded at higher levels will require materials that can only be obtained by defeating bosses you will encounter During several quest chains spanning 2 or 3 zones. The end result will be a crafted purple, or “rare” quality item. This is why I’m starting to think crafting was simply meant to be a way to reward players for fully completing a series of maps and quests by providing powerful gear that otherwise can’t be earned any other way during the leveling process. If that’s the intention then I like the way crafting is implemented as it makes the gear feel more meaningful because of how long it took to obtain everything. It also makes it more rewarding because it’s the only way to earn such a powerful piece of gear.

This robe required a recipe earned as a quest reward as well as ingredients obtained by defeating three different bosses over as many maps.
I’m still hoping there may be more to crafting in Tree of Savior, but if not I think the system works with the simplicity of the game. While it may be limited at early levels I like that crafting an item feels important once you’ve finally gathered everything. And since crafting isn’y a skill to level you aren’t required to make a pile of vendor trash in order to reach the next tier. Instead you work through the story quests to earn the ingredients needed to make a useful item that cannot be obtained anywhere else.
