Destiny 2 Cipher Decoders explained: Sources, drop rate and best ways to get Cipher Decoders explained

How to get your hands on the Halloween event-exclusive resource.

Destiny 2's Cipher Decoders are a resource added as part of the Festival of the Lost 2020 event.

These keys allow you to open chests in the Haunted Forest activity, giving you a range of rewards, including the return of the Braytech Werewolf and Horror Story auto rifles, event shades, legendary gear and of course, Festival of the Lost masks.

This page explains how to find Cipher Decoders, the best methods - including a farm - as well as the drop rate for when they first appeared in-game.

How to get Cipher Decoders in Destiny 2 and current drop rate explained

Replacing Fragmented Souls and other Festival of the Lost-specific currencies from previous years, you need Cipher Decoders to open chests within the Haunted Forest during the 2020 event.

Once you have visited Spider as part of the event's opening questline, Cipher Decoders will be rewarded from certain activity completions. They drop from every activity except the following:

  • Gambit
  • Forges
  • Non-playlist strikes
  • And enemy kills

You do not need to wear a Festival of the Lost Mask for drops to appear, either.

This guidance was updated on October 9th, after Bungie previous said drops would behave similar to Umbral Engrams.

Since launch, on October 8th Bungie announced it had "drastically increase[d]" drop rates, and then the next day, adjusted the rate further so two Cipher Decoders would drop where applicable.

Bungie added it will "continue to monitor feedback", so it is possible drop rates may change further.

What are the best ways to get Cipher Decoders in Destiny 2?

As you source Cipher Decoders from activity completions, the best methods are, quite simply, the fastest ones. This includes patrol missions - which can be done in a few minutes - and Heroic story missions, which according to Darkts3 on reddit, can take less than five minutes depending on the ones available.

Cipher Decoders reward masks, legendary gear and auto rifle rolls from previous Festival of the Lost events.

Elsewhere, it's been suggested completing Nightfall: The Ordeal during double bonus weeks - such as the week which is opening the Festival of the Lost event - has seen decent drop rates, likely because you have two chances of it being rewarded when the activity ends.

Ultimately, it's about what you enjoy playing. In theory the drop rate is the same, so it's a balance of playing activities you want to play that also can be completed within a reasonable time frame.

Beyond that, there is a farming method the community has discovered in you're in a hurry...

Cipher Decoder farming method explained

One method discovered by the community is loading into the Spire of Stars raid. Reach the final checkpoint, and have at least one other party member in your fireteam.

From there, you want to be in orbit, then opt to change character as you load back in, forcing you out of the activity. When you return, the fireteam leader will get completion drops - including a decent chance at a Cipher Decoder.

The method is shown clearer in this video by Aztecross, if you fancy trying it:

Late last year we saw the Bungie 30th Anniversary, which adds the Grasp of Avarice dungeon, Strange Coins and new Exotics, including the Gjallarhorn and Forerunner.


How many Cipher Decoders can you hold in Destiny 2?

You can hold up to a maximum of 25 Cipher Decoders at once - from there, you need to open some chests in the Haunted Forest before you can collect more.

There are five chests maximum in the Haunted Forest, giving you an idea of how many you can clear from your inventory in a single run.
