Raising and Evolving: By giving your Partner Machinery weapons and Atlantica Gold 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.

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.
