History of Deep Weapon Focusing

Deep Weapon Focusing is a Sonar Station upgrade from Season of the Deep. It lets you spend Deep Engrams and Glimmer to focus a specific Season of the Deep or Reckoning weapon you already own, giving it new stats and rolls. Focusing is done in the Deep Engram Decoding menu at the Sonar Station.

It is unlocked by completing its seasonal challenge, which requires collecting six different Season of the Deep or Reckoning weapons. The bonus also raises the Engram cost of decoding, from 2 to 4 Engrams.
