Nyleth is one of three Old Heart bosses you must defeat in Act 3 of Hollow Knight Silksong, found in a hidden section of the Grand Gate after defeating Shrine Guardian Seth.

Finding Nyleth’s Hidden Arena

Location Requirements

Before you can even attempt to face Nyleth, you’ll need to have progressed significantly through Silksong’s sprawling map. From the Grand Gate Bench, go left once you reach the vertical corridor. Use the Silk Soar ability to fly upward and cling to the left side of the wall halfway up. This hidden entrance is completely unmarked on your map, making it one of the game’s best-kept secrets.

The path to Nyleth requires careful exploration:

Start at Choral Chambers Ventrica Station – Fast travel here if you’ve unlocked it
Descend to Grand Gate – Navigate downward through the vertical shaft
Find the Breakable Wall – When in the vertical shaft, about halfway down the left wall, there will be a breakable entrance.
Navigate the Flower Maze – Drop through vines and follow the westward corridor
Defeat Shrine Guardian Seth – This mini-boss blocks your path to Nyleth
Activate the Bench – Make sure you activate the bench to the right of the elevator shaft. It costs 15 Rosaries, but only for the first time.

The Memory Fight Advantage

Here’s something crucial that many players overlook: This is a memory fight, one where you fight the boss in a version of the past. This means that you can use as many red tools as you want, and you don’t have to re-craft them when you wake up. This unique mechanic means you can go all-out with your most powerful consumable tools without worrying about resource management – perfect for players struggling with the wall-based combat mechanics.

Boss Overview: Understanding Nyleth’s Mechanics

Lore and Background

Shellwood was created thanks to Nyleth’s power who gave life to the vegetation in the area. After her death, her legendary figure was showcased as a statue in a shrine. As the ancient heart of Shellwood, Nyleth maintained the forest’s delicate balance, allowing safe passage for bugs across its branches. Now corrupted and hostile, she represents one of three Old Hearts you must collect to unlock Silksong’s deeper mysteries.

Arena Dynamics

The Nyleth boss fight features one of the most unique arenas in all of Silksong:

Phase 1 Arena:

In the first phase, the arena consists of a horizontal room with a central platform that covers half the map, with vines at the bottom, at the top and on the wall Nyleth is grappled onto.
Central platform provides initial safety
Spikes line the floor and ceiling
Wall-switching mechanics already in play

Phase 2 Arena:

In the second phase however, the arena gets expanded downwards, with longer walls and now the central platform missing.
No ground platforms whatsoever
Extended vertical space for dodging
Increased reliance on wall-gripping and aerial movement

Damage Values and Health

While exact health values vary by difficulty, Nyleth has relatively low health compared to other Act 3 bosses. From what I can see, it seems like this boss has quite a bit less health than others (though this might just be because you can hit her a lot faster). Most attacks deal two masks of damage, making positioning crucial for survival.

Complete Attack Pattern Breakdown 2025

Phase 1 Attacks

1. Wall Dash

Before jumping to the other wall, Nyleth crouches in her petals and the vines disappear from her wall. After half a second, she leaps and crosses the entire room horizontally, landing on the opposite wall.
Telegraph: Crouches and vines retract
Counter: Jump or use Swift Step to dodge
Opportunity: Pogo attack during her travel

2. Head Swings

Nyleth brings her neck down and after a half second she swings her head around at incredible speeds, cutting a large area directly in front of her and above her.
Telegraph: Head pulls back slightly
Counter: Create distance immediately
Damage Zone: Large frontal arc

3. Pollen Barrage

Nyleth reveals multiple sacks of pollen in her mouth which she starts throwing in Hornet’s direction in alternating quantities, between three and four projectiles released at once for four times.
Pattern: 3-4 projectiles in alternating spreads
Counter: The simplest way to dodge this attack is to go to the opposite wall of where Nyleth is positioned and just stay on the gaps between the projectiles.
Duration: Four volleys total

4. Thorn Balls

Nyleth will summon spheres of torns from the ground that move in a vertical motion.
Telegraph: You’ll see a stream of smoke on the exact spots where the spheres will emerge.
Counter: Position between the spheres
Timing: Brief hover before falling

Phase 2 Exclusive Attacks

5. Pollen Screech (Massive AoE)

Nyleth pulls her head backwards and starts charging up pollen that covers three quarters of the room, which is avoidable only by clinging onto the opposite wall.
Telegraph: Glowing aura builds around Nyleth
Counter: The only way to dodge this attack is to stay on the opposite wall of where Nyleth is positioned.
Damage: Devastating if caught
Recovery Time: Brief window for counterattack

During Phase 2, all previous attacks continue but with modifications:

When Nyleth reaches phase two, the number of spheres of torn that she summons will increase.
Head Swings now cover area below Nyleth as well
Increased projectile density in Pollen Barrage

Best Tools and Equipment Setup

Essential Tools Tier List

S-Tier (Must Have):

Ascendant’s Grip (Yellow Tool)
- Ascendant’s Grip is also perfect for this boss as it allows to remain completely still while holding onto the wall, making it easier to throw tools at Nyleth without fear of missing.
- You can adjust your position by letting go to drop quickly or tapping down to inch lower, which is key for dodging projectiles mid-cling.
- Found in: Chapel of the Wanderer area
- Why it’s essential: Eliminates wall-sliding panic
Cogfly (Red Tool)
- Cogfly allows you to deal passive damage when you get close to Nyleth and attack, which helps a lot in terms of dealing damage given how difficult the fight becomes once the platform collapses.
- Auto-targets while you focus on positioning
- Works perfectly with Pollip Pouch for poison synergy

A-Tier (Highly Recommended):

Pollip Pouch (Blue Tool)
- Adds poison damage to all red tools
- It applies a poison effect to every single Red Tool meaning if you hit an enemy with it, they’ll take some extra poison damage.
- Synergizes perfectly with Cogfly for passive DOT
Longclaw (Tool Upgrade)
- Extends pogo attack range significantly
- Essential if struggling with aerial positioning
- Makes Phase 2 considerably easier
Volt Filament
- Pale Nails or Thread Storm coupled with Volt Filament deals a lot of damage.
- Adds electrical damage to silk skills
- Great for burst damage windows

B-Tier (Situational):

Wispfire Lantern
- Auto-targeting wisps provide additional DPS
- Consumes silk but worthwhile for passive damage
- Found in Wisp Thicket area
Voltvessels
- Voltvessels, on the other hand, can exploit the boss’s position throughout the fight and deal a ton of damage.
- Position-based electrical damage
- Effective when Nyleth is stationary

Optimal Crest Selection

Top 3 Crests for Nyleth:

Hunter Crest (Best Overall)
- hunters crest has a much better pogo for this situation because you don’t need to be as close to the boss to initiate the attack.
- Diagonal pogo attack provides safer engagement distance
- Fast silk generation for healing
- Can be upgraded through Eva for additional benefits
Witch Crest (Aggressive Option)
- Witch Crest’s Silk Bind gives you another damage source that can also take advantage of the boss’s positioning.
- Rapid attack speed generates silk quickly
- Silk Bind provides additional ranged damage
- Best for experienced players
Beast Crest (Risk/Reward)
- Powerful Silk Bind buff when at low health
- Extended attack range beneficial for wall combat
- Healing mechanic works during combat
- High skill ceiling but rewarding

Crests to Avoid:

Wanderer Crest – Short range problematic for this fight
Architect Crest – Resource-heavy for a dream fight
Shaman Crest – Available too late (Act 3 only)

Phase-by-Phase Strategy Guide 2025

Phase 1 Strategy (Platform Available)

During the first phase, you have the luxury of a central platform, making this the ideal time to maximize damage output:

Opening Moves:

Immediately activate Cogfly if equipped
Position yourself on the platform’s edge nearest to Nyleth
Use rapid needle strikes to build silk quickly
Save silk skills for Phase 2 unless confident

Positioning Tips:

For most of Phase 1, you can stand next to her and just wail on her, dodging when necessary.
Stay mobile but don’t waste jumps
Use the platform to reset positioning after each attack sequence
When Nyleth dashes, follow to the cleared wall immediately

Attack Windows:

Post-dash: 2-3 seconds of free damage
After Pollen Barrage: Brief recovery period
Between Thorn Ball waves: Quick pogo opportunities
During Head Swing wind-up: Get 1-2 hits before retreating

Phase 2 Strategy (No Platform)

Once this next phase begins, the platforms you’ve been standing on will disappear completely, forcing you to cling to the wall for the entirety of the rest of the fight.

Survival Priorities:

Master the Ascendant’s Grip timing – Don’t panic-grip constantly
Choose your wall wisely – Stay on the wall to avoid ground spikes. Watch for Nyleth’s dash across the arena. When she crosses under you, pogo her once or twice before repositioning.
Conserve silk for emergencies – Healing opportunities are rare

Advanced Pogo Strategy:

What’s nice is that the arena opens up a bit, so when she uses her Pollen Blast attack, you can avoid it by floating in the small area above her head instead of heading to the opposite wall.
Use Hunter Crest’s diagonal pogo for safer approaches
Chain 2-3 pogos maximum before retreating
Never commit to extended pogo chains during Pollen Screech charge-up

The Safe Loop Strategy: A simple strategy you can do to win the fight is to start at the opposite side of where Nyleth is positioned while wall jumping constantly to prevent falling. If you want to attack, do a Double Jump towards the boss and deal as much damage as possible using skills, tools, and attacks.

This conservative approach prioritizes survival:

Cling to opposite wall
Wait for Nyleth to commit to an attack
Double jump + Swift Step toward her
Get 2-4 hits
Clawline back to safety
Repeat until victory

Common Mistakes and How to Avoid Them

Mistake #1: Panic Gripping

Many players death-grip the walls constantly, leading to poor positioning and missed dodge opportunities.

Solution: Use Ascendant’s Grip to pause and plan movements
Practice: Spend time in earlier areas practicing controlled wall releases

Mistake #2: Greed During Phase 1

Players often try to maximize Phase 1 damage and take unnecessary hits.

Solution: Focus on learning patterns rather than DPS racing
Remember: Nyleth is probably the easiest out of the 3 Heart bosses.

Mistake #3: Ignoring Tool Synergies

Using random tools without considering combinations reduces effectiveness.

Solution: Stack poison (Pollip Pouch) with multi-hit tools (Cogfly)
Optimize: Test tool combinations at benches before the fight

Mistake #4: Poor Silk Management

Wasting silk on poorly-timed skills leaves you unable to heal.

Solution: Save silk skills for guaranteed hit windows
Priority: Healing > Damage in Phase 2

Mistake #5: Fighting the Camera

The vertical arena can cause disorientation, especially during wall swaps.

Solution: Using your clawline to close the gap and clawline back will hasten the fight and help you avoid her ridiculously massive AoE attack.
Tip: Use visual landmarks on walls to maintain orientation

Speed Strategy for Experienced Players

For those looking to optimize their clear times or attempting challenge runs:

Hyper-Aggressive Loadout:

Crest: Beast or Witch
Red Tools: Thread Storm, Voltvessels, Cogfly
Blue Tools: Pollip Pouch, Weavelight, Druid’s Eye
Yellow Tool: Ascendant’s Grip (non-negotiable)

Speedrun Tactics:

Phase 1 Burst: Use all silk skills immediately while platform exists
Tool Spam: Since it’s a dream fight, use every red tool liberally
Pogo Chains: Master 4-5 hit pogo chains during her wall transitions
Skip Dodging: Tank certain attacks if you have Fractured Mask active
Clawline Cancel: Use clawline to cancel attack animations for faster DPS

Time Benchmarks:

Casual Clear: 3-5 minutes
Optimized Clear: 2-3 minutes
Speedrun Potential: Under 2 minutes

Alternative Strategies for Different Playstyles

The Tank Build

For players who prefer trading hits:

Tools: Fractured Mask, Warding Bell, Shield Dart
Strategy: Face-tank smaller attacks, only dodge Pollen Screech
Pros: Simpler execution
Cons: Resource intensive, risky in Phase 2

The Summoner Build

Let your tools do the work:

Tools: Cogfly, Wispfire Lantern, Voltvessels
Strategy: Focus entirely on dodging while summons damage Nyleth
Pros: Safe, consistent damage
Cons: Slower kill time, silk-hungry

The Skill Spammer Build

Maximum silk skill usage:

Crest: Shaman (if available) or Hunter
Blue Tools: Spool Extender, Weavelight, Egg of Flealia
Strategy: Build silk rapidly, unleash powerful skill combos
Pros: High burst potential
Cons: Requires excellent silk management

Post-Victory Rewards and Progression

The Pollen Heart

Upon defeating Nyleth, You’ll obtain the Pollen Heart item after defeating Nyleth. This is one of three Old Hearts required for:

Accessing the Red Memory – Crucial for story progression
Obtaining the Everbloom – Essential late-game item
Unlocking True Ending paths – Required for 100% completion

Additional Benefits

Lore Tablet Access – New story revelations about Shellwood

Frequently Asked Questions

Can I retry Nyleth if I fail?

Yes! Thankfully, there’s basically no runback, so feel free to be aggressive. The bench is located immediately outside the boss arena, making retries quick and painless.

Do I need specific upgrades to beat Nyleth?

While not strictly required, having at least Needle Level 2 and 6+ masks is highly recommended. The Clawline ability is essential, and Ascendant’s Grip, while optional, makes the fight significantly easier.

What’s the best time to attempt Nyleth?

Most players attempt Nyleth in mid-to-late Act 3 after acquiring several movement upgrades and tool options. Nyleth is probably the easiest out of the 3 Heart bosses, making her a good first choice among the three.

Why don’t my red tools break in this fight?

This is a memory fight, one where you fight the boss in a version of the past. This means that you can use as many red tools as you want, and you don’t have to re-craft them when you wake up. Take advantage of this unique mechanic!

Can I cheese this boss fight?

While there’s no true “cheese” strategy, the Cogfly + Pollip Pouch combination while wall-clinging comes close. Some players have also found success with the “opposite wall strategy” where you simply stay far away and only attack during her wall transitions.

Is Nyleth required for the normal ending?

No, Nyleth and the other Old Hearts are only required for the true ending paths. However, completing these optional challenges provides significant lore and some of the best boss fights in the game.

What if I can’t do the wall combat?

If wall-based combat is particularly challenging for you:

Practice in safer areas first
Overlevel your equipment
Use the Longclaw for extended pogo range
Consider using accessibility mods if on PC
Remember that Clover Dancers can actually substitute for one of the other three Old Hearts

How does Nyleth compare to other Silksong bosses?

In terms of difficulty, Nyleth sits in the middle tier of Silksong bosses. She’s easier than late-game challenges like the other Heart bosses (Khann and Karmelita) but harder than most Act 1 and Act 2 bosses due to her unique arena mechanics.

Conclusion

Nyleth represents one of Hollow Knight Silksong’s most unique boss encounters, transforming traditional combat into a vertical wall-dancing challenge that tests every skill you’ve developed throughout your journey in Pharloom. While initially intimidating, the fight becomes manageable once you understand that patience and positioning trump aggressive damage dealing.

Remember these key takeaways:

Ascendant’s Grip is virtually mandatory for maintaining control
Phase 1 is your damage window – don’t waste it learning patterns
The opposite wall strategy works if you’re struggling with complex movements
It’s a dream fight – spam those red tools without concern

Whether you’re a completionist hunting for every achievement, a lore enthusiast uncovering Pharloom’s mysteries, or simply trying to progress through Act 3, defeating Nyleth marks a significant milestone in your Silksong journey. The Pollen Heart she guards isn’t just another collectible – it’s your key to uncovering the deeper truths hidden within this beautifully crafted world.

Keep practicing those wall jumps, perfect your pogo timing, and remember: in a game where the ground is literally lava (or spikes), sometimes the best strategy is to never touch it at all. Good luck, and may your silk never run dry when you need it most!
