Seasonal Bonuses

Seasonal Bonuses is the in-game tab of the Seasonal Challenges menu that lists the upgrades for the Sonar Station, the vendor in the H.E.L.M.'s Wing of the Deep for Season of the Deep. Upgrades unlock by completing specific seasonal challenges rather than by purchase. Guides also refer to the same list as a "Season of the Deep" subsection of the Seasonal Challenge menu.

• Deep Challenger: completing the weekly Season of the Deep activity challenge gives a chance at an extra Deep Engram.
• Deep Armor Focusing: unlocked by obtaining a full set of Season of the Deep armor, allowing Deep Engrams to be focused into high-stat armor.
• Deep Weapon Focusing: unlocked by obtaining six Season of the Deep or Reckoning weapons.
• Synchronized Swimming: requires Rank 7 with the Sonar Station. Chests give bonus reputation that scales with fireteam members who also have the upgrade.
• Deep Attraction: requires Rank 13 with the Sonar Station. Activities have a chance to drop an extra Deep Engram.
• Forgotten Treasures: as a fireteam, complete three jobs within a single Salvage activity without failing. Salvage Keys and Deep Dive Keys can then drop an additional Deep Engram when used.

The tab also lists Efficient Angler, Deepsight Salvaging, Deep Sea Locksmith and Dive Station.
