After a Guardian graduates from the academy, they are assigned a Partner Machinery. A Partner Machinery is used for item, mission, and information management. They normally reside in your character's apartment, unless you take it with you in your adventures. You can use them to store raw materials as well as produce items. Ethan's Partner Machinery in Story Mode is named PETE.

In Phantasy Star Online, an Item Bank was available to hold extra items. The Item Bank has been abolished in Phantasy Star Universe and item maintenance is now handled by the Partner Machinery. You will be able to deposit items and withdraw them, just like you used to at the Item Bank.

By giving your Partner Machinery weapons and items, its stats will grow. It will transform into various forms as it gains levels through stat growth. As your Partner Machinery transforms, it will be able to create better items. The items it produces can also change depending on how it was raised. Once the Partner Machinery has transformed into its humanoid form, it will present you with its partner card. You will now be able to summon your Partner Machinery and take it with you into battle.

As noted above, you will be able to give items to your Partner Machinery. In this screenshot Ethan is seen giving a Gigush with 149 PP, 166 ATP, and 80 ATA to PETE. PETE has 0 POW, 0 DEX, 0 MIND, and 0 DEF here.

In these two screenshots, Ethan gives a Picque to PETE. This causes it to gain +8 in the POW category and evolve into its humanoid form. The Partner Machinery then gives Ethan its Partner Card so they can go into battle together.

Using item synthesis, you will be able to create a wide variety of items, including rare and expensive weapons. Here is an overview of how the system will work. First, you must find the "board" for the item you want to make and give it to your Partner Machinery. You will be able to find boards while fighting or by them from a specialty store. Next, you must gather the ingredients necessary to make the item. Like boards, you can buy ingredients from the store or find them while adventuring. After that, talk to your Partner Machinery and ask it to make the desired item. Depending on the level of your Partner Machinery and the item being made, there is a chance the synthesis may fail. It is worth noting that you can only synthesize a certain number of items for any given recipe. Also, you can synthesize multiple items, such as 10 dimates, at one time.

As you progress through Story Mode, you will eventually receive a "synthesis kit." This will allow your Partner Machinery to combine and create new items for you. The items your Partner Machinery is best at making will change as it evolves. Also, you will be able to use item synthesis in Network Mode.

In the first screenshot below, Ethan receives his Item Synthesis kit from Lumia. Ethan puts this kit to use in the second screenshot. He is seen trying to perform a 4 slot synthesis involving a Twin Power Gun, Imu Photon, Keleserin, Hapotite, and Bal Epon. The chances of success are 64%. PETE is quoted as saying, "If I fail at this synthesis, please do not be angry with me."
