Microphasic Datalattice

The Microphasic Datalattice is an Uncommon planetary material in Destiny 2. Its in-game description calls it "encrypted data inaccessible in an unknown hybrid state of matter-energy."

You collect it by interacting with Datalattice nodes in Arcadian Valley on Nessus during Patrol activities. Taking it to Failsafe in the Exodus Black raises your reputation with the Nessus faction. It also counts toward Nessus challenges that ask you to gather 10 Microphasic or Quantized Datalattice.
