Hollow Knight: Silksong hides more secrets than a termite's daydream, and as of 2026, Eva remains one of the most frequently missed NPCs in the game. Tucked inside a pod in Weavenest Atla, Eva initially appears as little more than a disembodied voice—easy to ignore if a player is laser-focused on bosses and platforming. Yet this peculiar encounter is a two-course meal: first, an upgrade for the Hunter Crest, and much later, a binding that grants the Sylphsong ability and the Entwined trophy. Think of Eva as an unread fortune cookie left in a silk cocoon, whispering riddles instead of lucky numbers.

Opening the Needolin Door in Moss Grotto

The search begins in Moss Grotto, the starting area that most players sprint through without a second glance. The Needolin door here remains sealed until someone plays the Needolin, and once it swings open, it reveals the path to Weavenest Atla. It is the kind of moment that feels like finding a trapdoor under a welcome mat.

After stepping through, players should keep moving right until they enter a room with two fuses, or power cells, jutting from the ceiling. Hitting both fuses restores power to Weavenest Atla, and the area stops feeling like a blackout basement. On the way back, grabbing the map is strongly recommended—no one wants to explore a silk-strewn labyrinth without a map.

Next, the player should stand on the central platform. This platform teleports Hornet to the lower section of Weavenest Atla. To the right, a path is blocked by wires; clearing that obstruction opens the way into Eva's chamber. It is a short detour, but it separates the thorough explorers from the tourists.

First Conversation and the Evolved Hunter Crest

Once inside, Eva speaks from the pod and offers Hornet a chance to accept their insight. Saying yes transforms the standard Hunter Crest into the Evolved Hunter Crest. While this Crest is equipped, Hornet can accumulate focus on consistent strikes. When that focus reaches maximum, needle damage rises sharply. In practice, it works like winding a clockwork hornet: every clean hit adds another click of tension, and the next needle thrust can land like a thunderclap.

Eva then asks Hornet to return after she has evolved further. That is not flavor text; it is a roadmap.

Collecting Every Crest and Unlocking Memory Locket Slots

To satisfy Eva's condition, players must gather all the Crests in Silksong and unlock their slots with the Memory Locket. This step is the longest part of the journey, and it can feel like collecting chrome hubcaps from seven different junkyard guardians, each bolted to a different corner of a hostile map.

Each Crest must have its slot unlocked through a Memory Locket, so simply finding them is only half the battle. Once everything is slotted, Hornet's growth is undeniable, and Eva is ready for a much closer relationship.

Binding Eva in Act Three

In Act Three, players can return to Eva's chamber in Weavenest Atla. Eva will notice Hornet's growth and ask to bind. Agreeing to the binding is where the side quest pays off in spectacular fashion.

The binding unlocks Sylphsong, one of the most useful skills in the game. With this ability, Hornet regenerates silk while resting on a bench, which makes later stretches far less punishing. It also pops the Entwined trophy or achievement, depending on the platform.

Why This Side Quest Is Worth It

The Eva detour is the kind of optional content that makes Hollow Knight: Silksong feel alive. It asks for patience, exploration, and a willingness to backtrack, but it hands out a powerful Crest upgrade, a bench-based silk regeneration ability, and a rare trophy. In short, it is like discovering a free dessert counter behind a bakery after everyone else left with only bread. Players should stop sprinting, play the Needolin, and let a silk-wrapped voice change the run.

For players who want to secure a physical copy or collector's edition of Hollow Knight: Silksong, prices tend to fluctuate wildly around major updates and anniversary sales. Rather than refreshing store pages every day, many fans rely on this price tracking tool to catch the best moment to buy, leaving more time free for another run through Pharloom.

Either way, whether the goal is a rare achievement or a better deal, a little preparation goes a long way in and out of the game.
