If you are wondering how to unlock the Weapon Decoding War Table upgrade, you will need to complete Seasonal Challenges. Completing specific Seasonal Challenges will reward you with one Insight. You can then use Insight back at the War Table to unlock War Table Upgrades.
Start by heading over to Seasonal Challenges under the Season tab. You can find the Season tab by opening the menu tab and locating it at the top right of your screen.
After clicking the Seasons tab, you can find Seasonal Challenges at the bottom of your screen. Under Seasonal Challenges, you can find two challenges that can earn you Insight, Operation Elbrus and Psychogenic Decoder.
You can complete the Psychogenic Decoder challenge by collecting Psychogenic Intel and collecting Risen Embral Energy. To complete Operation Elbrus, you will need to defeat enemies in PsiOps Battlegrounds.
That said, once you get your hands on Insight, you can use it back at the War Table to unlock Weapon Decoding. When you unlock Weapon Decoding, you can unlock Seasonal weapons by going to the second page in the War Table. On the second page, you can unlock seasonal weapons for the following resources:
- 1 Umbral Engram
- 50 Legendary Shards
- 9 Risen Umbral Energy
