Hollow Knight: Silksong is packed with hidden mechanics and secret NPCs, and Eva is one of the most important late-game encounters. Binding her not only unlocks the Sylphsong ability—a powerful upgrade to Hornet’s healing—but also grants the Entwined achievement. This guide explains who Eva is, where to find her, the requirements to unlock the bind option, and why it’s worth completing.
Who is Eva?
Eva is a hidden NPC found in Weavenest Atla, deep beneath Pharloom. Unlike other bindings that affect combat or exploration directly, Eva’s connection is tied to Hornet’s healing system. She begins by upgrading your Hunter Crest and later offers the option to bind with her, permanently changing how silk management works.
Her story carries a tragic weight, and once you bind with her, Eva disappears forever. This makes her one of the most memorable late-game NPCs in Silksong.
Where to Find Eva (Weavenest Atla Location)
To reach Eva, you’ll need the Needolin Ancestral Art, which unlocks certain spider-marked doors across Pharloom.
- Travel to Bone Bottom via the Bellway.
- Exit left and drop down a hole leading back to the game’s starting area.
- Head right into a spike-filled platforming room. At the far end, you’ll find a door marked with a Weaver’s mask.
- Use Needolin to open the door and enter Weavenest Atla.
- Move right, activate the lamps and ceiling triggers to restore power, and then use the central beam elevator to descend.
- Explore the lower east section, breaking hidden walls, until you find Eva’s chamber.
At first, she’s trapped within a pod, and you’ll only hear her voice. Once freed, Eva offers Crest upgrades tied to your progress.
What You Need Before Binding Eva
Binding Eva isn’t available right away. You must show Hornet’s growth by collecting Crests and unlocking their slots using Memory Lockets.
- Crests Required:
- Hunter Crest (default)
- Wanderer Crest
- Reaper Crest
- Beast Crest
- Witch Crest
- Architect Crest
- Shaman Crest (late-game)
- Memory Lockets: Use them to fully expand the slots of your Crests. Most guides agree you need around 17–20 Lockets, with the Hunter Crest fully maxed first, since Eva upgrades it initially.
If the Bind prompt doesn’t appear, return after unlocking another Crest, slot, or advancing the story.
How to Bind Eva in Silksong (Step-by-Step Guide)
Once you’ve met all requirements, revisit Eva and follow these steps:
- Prepare Your Crests.
- Ensure you have at least 6 Crests fully unlocked with Memory Lockets. Rest at a nearby bench before heading in.
- Return to Weavenest Atla.
- Play the Needolin at the spider-marked gate each time you re-enter, as the door reseals. Use the beam elevator and clear the eastern passage again to reach Eva.
- Exhaust Dialogue.
- Speak to Eva repeatedly. She’ll gradually give you upgrades: extra Crest slots, Hunter Crest evolutions, and unique Vesticrests. Once you’ve collected everything, she’ll ask for her final wish.
- Perform the Ritual.
- Accept the option to bind with her. Hornet absorbs Eva’s essence in a non-combat ritual, gaining the Sylphsong ability.
- Achievement Unlock.
- The Entwined achievement (or trophy) is awarded immediately. Eva vanishes permanently afterward.
How Sylphsong Works After Binding Eva
Sylphsong is one of Silksong’s most useful late-game abilities. It automatically restores Hornet’s silk when resting at a bench. This means you no longer need to grind combat encounters just to refill silk, streamlining both exploration and boss preparation.
Benefits of Sylphsong:
- Refills silk instantly at every bench rest.
- Enables consistent use of Bind (Hornet’s healing art).
- Perfect for tough late-game areas with limited combat opportunities.
- Works best when paired with fully upgraded Crests for hybrid builds.
Best Strategies for Binding Eva in Silksong
- Delay Binding Until Ready. Eva disappears after binding, so collect all Crest upgrades she offers first.
- Farm Memory Lockets Early. They’re essential to unlock the bind prompt—don’t leave them for the very end.
- Test Sylphsong Immediately. Rest at a bench after binding to confirm the ability is active.
- Plan for Boss Runs. With Sylphsong, benches become true resource hubs, letting you focus entirely on mechanics.
Binding Eva is more than just a mechanical upgrade—it’s one of Silksong’s most emotional story beats. By fulfilling her final request, Hornet gains Sylphsong, a skill that reshapes healing and progression. While it comes at the cost of losing Eva, the payoff is immense: smoother exploration, faster recovery, and one of the game’s most significant trophies in Entwined. Play Now!
