Currently, there are five possible stars of rarity per classification of equipment.
- Wood: 1-5 yellow stars
- Metal: 1-5 blue stars
- Military: 1-5 green stars
- Golden: 1-5 gold stars
- Carbon: 1-5 red stars
A higher star count equates to a better part. For example, a five-star wooden part is better than its one-star counterpart. However, a one-star metal part is better than a five-star wooden part. This pattern applies to all part classifications.
Each classification has a different visual style. Wood is light brown (and looks like wood, hence the name), metal is a metallic blue, military is olive green, gold is a shiny yellow, and carbon can be black, red, or silver, depending on the particular part.
