Silksong’s Act Three, The Abyss, is one of the main quests of the game, but it doesn’t unlock automatically. To get there, you’ll need to complete a series of side quests, gather special items, and prepare for the final boss. In this guide, we’ll walk you through everything you need to do so you can unlock Act Three and continue your adventure smoothly.
How to Start Act Three in Silksong

The first thing you need is the quest called Soul Snare. But before you can get it, there are several side quests you have to finish, mostly in the Coral Chambers area. You’ll find the quest board there, and the final side quest in this questline is Silk and Soul. To progress, you’ll also need to collect enough fleas scattered across the map. Once you gather them, you can move the caravan all the way to Fleatopia, located on the right-hand side of the Putrified Ducts. Unlocking Fleatopia will make the Soul Snare quest available on the quest board.
Claim Your Bellhart Home

Another requirement is claiming your Bellhart home. Head to the NPC in Bellhart who gives you a key this will allow you to access a home on the upper-left side of the map. Once you’ve unlocked Fleatopia and claimed your Bellhart home, check your quest board to see if you’re missing any side quests. Completing them all will lead you to the final quest, Silk and Soul.
Preparing for the Final Boss

After finishing Silk and Soul, it’s time to make your way to the Cradle. At the top, you’ll meet the caretaker NPC, who will tell you that the snare is set. Instead of binding the boss after defeating it, you’ll use your Needolin.
Speak with the caretaker, then proceed upwards to fight the final boss. Once defeated, use the triangle key with your Needolin. This will trigger an alternative ending and unlock a special achievement. After that, the game will roll into the end credits. Once the credits finish, your save file will be updated, and you can begin Act Three: The Abyss.
