How to unlock Eclipse threads in Saros
Since Eclipse Threads is a story-related ability, players unlock it automatically as they progress further into the game. However, for players who want more specific details on the location of this power-up, you must first complete the fourth biome by defeating the boss, Legion. This is one of the easier bosses in the game, but having an Auto-Hit weapon with you is recommended so that your weapon can determine which of the flying enemies is the main boss.
Once the boss is down and you complete a few story segments back Passageyou will be able to travel using World dial to the entrance of the next biome, A desecrated fortress. Besides Honorary sigils which you start to find in this biome, after clearing a few rooms you will see the Eclipse device.
There is no way forward, so the only option is to activate the device, and when you do, a small yellow key item will appear in front of you. While Arjun is talking to his suit, grab the shiny object from the ground to unlock the Eclipse Threads ability. This allows you to navigate large rooms with ease by pressing the L1 buttonwhich you use for hatching.
With Eclipse Threads unlocked, you can now revisit previous biomes and open certain doors or containers that were inaccessible because Arjun didn't have this ability. IN Ancient depthslarge room where you have to activate the eclipse device and inspect the two rooms on the sides of the vault has an Eclipse thread that takes you to the Nightmare Strand. Since they are associated with a gold trophy, they are worth completing at least once in each biome.
It is important to note that the Eclipse Threads capability can only be used when Eclipse is active.
