Deep Dive Key

Deep Dive Keys are a legendary seasonal currency from Season of the Deep.

Acquisition

Deep Dive Keys drop from various activities. The Deep Sea Locksmith upgrade at the Sonar Station gives a chance to earn one when you redeem a Salvage Key. The Forgotten Treasures upgrade gives a chance at an additional Deep Engram when you redeem a key in Salvage or Deep Dive activities.

Use

A key is used automatically when you open a Deep Chest at the end of a Deep Dive, which improves that chest's rewards. Up to two Deep Chests can appear at the end of a Deep Dive.
