Item synthesis

Item Synthesis uses the Partner Machinery to create items (such as Weapons, Armors and consumables) from base materials bought from Synthesis Shops or found during Missions. Item Synthesis is affected by success rates; the success rate of synthesizing a particular item depends on the item's type and the levels of the Partner Machinery.

Synthesis Boards are placed into the Partner Machinery from the inventory and materials are gathered from storage to synthesize the items. Up to 32 Synthesis Boards can be inserted into your Partner Machinery at a time. If another Synthesis Board is inserted after the limit is reached, your PM will ask you to select an already inserted Synthesis Board to replace with the new one.

Consumable items have a 100% synthesis success rate and synthesize immediately. Other items have synthesis success rates that vary with the Partner Machinery's Production Level in a corresponding attribute and require time to synthesize, after which they can be retrieved from the Partner Machinery.

Process

#	Process
1	After inserting your Partner Machinery with the proper Synthesis Board (Done through the Synthesis menu), put into your Partner Machinery's storage the proper materials the recipe calls for. Note the large red Xs listed, those are telling you you don't have the proper materials in the Partner Machinery storage (you just can't have the items on you).
2	Verify with your PM that the Ingredients necessary are there. Note the success rate for your item as well as the number of uses left that Recipe can generate at the bottom.
3	Wait the specified amount of time; usually 90 minutes. The stronger the item, the more time it takes. If it's an armor, it takes even more time. If its got a success rate of 100% (usable items and most forms of refining), it will be instant. Note that you can cancel it and get back your materials should you have to, however, if a considerable amount of time has passed, you may not be able to get back the materials used. You can check on the status of your weapons, and how much resource has been used, anything unused will be returned to you, anything used has a success rate of retrieval. The synthesis process might take several hours.
4	Finalize synthesis, and pick up your items. At this point, you can still cancel synthesis and make an attempt at getting your resources back. Picking up only applies to armors, weapons, and high level refining. This is essentially the moment of truth, time to see if your PM successfully created/refined the item or not. If you fail, you'll end up with a useless item, such as a Monomate.

Notes

For Step #2, keep in mind each type of item built will follow a standard formula that never changes: General items that are catalysts (not usable, like grinders, or resource refining with the exception of high level ore refining) consist of one item, which is usually the material itself, and labeled as such (things such as "Grinder C Parts"). Recovery Items and high level ore refining consist of two types of ingredients, chemicals and natural materials, and acids for usable items; lower level ore and basic photons; use more expensive photon for high level refining. Armors require three kinds of resources: photons, ores, and materials (such as nanocarbon, or orta-resin). Finally, weapons require the most of anything, filling all four resource slots, consisting of ores, photons, metals and wood.

• NOTE: If you evolve your Partner Machine, the synthesis success rates will go up. Sometimes success rates can go up to 10% with one evolution.
