Star Ocean 5 allows you create a seemingly endless number of items from raw materials with an extensive crafting system. There are a number of ways you can exploit the system to unlock the synthesis creating ability early, and get the most out of Star Ocean 5’s crafting system.

The Synthesis system is unique and different from the normal item creation system, as synthesis means you never quite know what you’re going to end up with when you’re crafting items together.

In order to narrow the variety of the results, you’ll need to do a few things. Determine the category of the result by selection food, machine, natural material, metal or signeturgy while in the “Result” area when you start making your synth. This will determine the type of items the results of your synth will fall under. It’s in this section that you’ll also find “qualities” and “impurities”, which will give you a small idea of how well the items you’re using work together.

Importantly, “Quality” has a maximum value of 50, while “Impurities” have a same maximum value but also let you know how many imperfections there are that limit the final product from being a legendary item.

Ultimately, it all comes down to luck, as the proposed rating doesn’t necessarily dictate the actual ration of the item, but you can still improve your chances. You have a shot at an ultimate synth so long as the quality and impurity ratings are 50.

Star Ocean 5 Synthesis Basics

The Synthesis speciality can be unlocked early through the Happy Fun Bunny Time quest. As mentioned above the primary difference between Synthesis and item creation is that with the former, using a set recipe of items will always create the same items, whereas with Synthesis, you could get between 2-6 different items, even if you’re used the recipe before.

When you’re in the process of arranging a synthesis, you’ll be able to manually fill the select, or fill it automatically using the Automatic Selection function. Either way, you’ll have plenty of information to work with.

Type could be medicine, food, mental, natural material, signeturgy, or medicine. Toggle through the different items to learn about the end item; Quality lists the potential overall level of the product. This will vary depending on the items you have used, and has a max level of 50; Impurities measures the amount of imperfections that hold the item back from being legendary status.

The below table shows the potential range that a particular Synthesis rating has.
