Step 3: Enhance and Evolve Your Part

1. Move to the Plastic tab, where you’ll find plastic parts that can be used to upgrade your item’s level (Parts Enhance) and its rarity (Parts Evolve).

2. Adjust the dial to increase the level or rarity of your part until you’re satisfied or run out of resources. Remember, the parts you need can be collected from Gunpla battles by breaking them off enemies.

3. And there you have it, equip your upgraded Gunpla parts to feel the difference in the heat of battle.
