Deep Challenger

Deep Challenger is a Seasonal Bonus from Season of the Deep, listed in the Seasonal Challenges section. It increases the number of Deep Engrams you receive. You unlock it by completing its associated seasonal challenge; no special currency is needed.

Deep Engrams are not sent to your inventory. They are stored at the Sonar Station, the season's main vendor in the H.E.L.M., and decoded there through the Deep Engram Decoding menu. You earn them by ranking up with the Sonar Station, and by playing Salvage and Deep Dive activities with their keys.
