Currently, there are five possible stars of rarity per classification of equipment.

  1. Wood: 1-5 yellow stars
  2. Metal: 1-5 blue stars
  3. Military: 1-5 green stars
  4. Golden: 1-5 gold stars
  5. 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.
