Rarities and upgrades

Rarity shows in the part's color and never changes.

Upgrades

• A part's rarity never changes. What goes up is its level, from 1 to 60.
• To upgrade, sacrifice parts you don't use, plus a fee in PN. At level 60 the stats reach double the level 1 values.
• The higher the level, the darker the steel: at 60 it turns polished black.

Paints

• Every part can be painted with paints from the Shop (some have textures or animation).
