According to the CAS armor guide on anarchyarcanum.com,
"For every part of the CAS armor you intend to create you will also need two Notum Fragments or Notum Chips, or one of each. These can not be lower than 10% of the Nanobots we only just now purchased, or the procedure wont work."
Is this a misprint? If not, why the demand for QL170+ Notum when much lower QLs will work?
