Datalattice is one of the five planetary resources in Destiny 2 and can only be collected on Nessus.
Datalattice is one such material that can be difficult to find, especially in large quantities – which is sometimes needed for certain quests in Destiny 2.
How this works is relatively simple: locate a Datalattice, collect it, and then zoom to the closest loading zone.
If you wish to avoid the grind of searching manually, you can instead exploit Destiny 2’s loading zones, forcing a Datalattice to remain active.
