The quality level, or QL, of an object is a measure of how pure/well refined/etc. that good is. A low QL will cause failures when attempting to fetch to a building. Higher QL goods are needed for production of higher tech level items, at a rate of 8 QL per TL (247 QL is required for TL 32, the current cap).

Quality levels are expressed as both a number between 1 and 255, and a descriptor:

  • Flawed (1-34)
  • Bad (35-74)
  • Poor (75-114)
  • Fair (115-154)
  • Good (155-194)
  • Fine (195-224)
  • Superb (225-255)
