Deep Armor Focusing

Deep Armor Focusing is a Sonar Station upgrade from Season of the Deep, unlocked through a seasonal challenge. Once unlocked, Deep Engrams can be focused into individual pieces of high-stat Season of the Deep armor at the Sonar Station, which also costs Glimmer.

Guides from 2023 disagree on the requirement. One says a full set of the season's NPA armor (six pieces) must be collected and the challenge rewards claimed before focusing works. Another describes the challenge as needing only one full set. Check the in-game challenge for the current requirement.
