As always with the secret chests in Destiny 2, they only drop the loot you already got from the dungeon. So if you only have a hand cannon and a class item from Sundered Doctrine, only those two can drop from the secret chest. The chests are also limited to one opening per week per character.

The door into the second encounter of Sundered Doctrine is a small test, set to teach you the mechanics you need to know. You’ll enter a room with symbol wheels on either side, enemies throughout, and a door ahead with a symbol on either side of it. You need to highlight those symbols on each of the wheels in order to open the door.

Here is what you can farm in Destiny 2's Sundered Doctrine dungeon with the full loot table, but dungeon weapon farming remains terrible.

Sundered Doctrine is one of Destiny 2'smore difficult dungeons, requiring players to conquer the horrors within Rhulk's derelict ship to earn new rewards. There are four Legendary weapons to chase and an exclusive Exotic if you're lucky enough to have it drop.
