Make nullity and grid armor quest rewards. You could even make it like the alvin quest I guess.
Part A.) Find some monsters that have the parts for the grid armor
part B.) Kill some dood that has a special component that is needed to make one of the nanos
etc...
Making these super rare items as quest rewards would be very good imho, because people could actually obtain them that dont have 150mill to spend on one nano for their twinks.
