Usage
s are often required to unlock new blueprints. The player must gather a required number of s and give them to Qi in Sandrock's Research Center for new blueprints.

Disc recovery
s can be given to Qi to obtain new assembly diagrams by speaking to him and selecting the "Research" social interaction.

Craft
are also used by the Relic Restoration Machine in the Museum to form relics out of relic pieces. Recovering each relic costs 10 s.
