As Festival of the Lost returns to Destiny 2, it brings a new mechanic. The Haunted Forest is now full of treasure caches that you can find by running around hitting all the ghouls and ghosts. You'll need Cipher Decoders to open them, however, you can't access this sweet loot for free.
To get your hands on these Cipher Decoders, you'll need to complete in-game activities. Just about anything that isn't the Haunted Forest itself should get you a Cipher Decoder, including Crucible Match, Strikes, and Nightfalls. The same hasn't gone live yet, but when it does, we'll keep an updated list of activities that have dropped crypto decoders for us so you can decide how best to farm them.
If you're wondering if these caches are worth opening, the answer seems to be yes, they are. They can contain random legendary gear, Festival of the Lost Shaders, and most importantly they can drop Braytech Werewolf and Horror Story auto rifles. Since it's still mostly Auto Rifle season, it's definitely a good way to farm a nice weapon. We don't yet know what kind of power cap they will have when it comes to weapon extinction, but they should be good for a few seasons.
You will only need one Cipher Decoder to open a Cache, but multiple Caches can spawn in a single run, so be sure to farm plenty of them before heading into the Haunted Forest.
