Hollow Knight Silksong Grand Mother Silk Boss Guide

After the hours spent exploring Pharloom's desecrated citadels, climbing its towers, cutting through its black caverns, and fighting some of the game's most challenging bosses, you come riding up to the last elevator at last. When you arrive at the top, Lace is once again defeated, and you enter the last great chamber. Standing in your way is none other than Grandmother Silk, a giant, woven creature of enormous strength who embodies the very strands that hold Pharloom together.

This is a fight steeped in atmosphere, but surprisingly, it isn’t the most punishing encounter you’ll face. In fact, many players find the Grand Mother Silk Silksong battle easier than optional fights like the Swarm or even earlier duels with Lace. Much like the Radiance in the first Hollow Knight, this boss feels more like a climactic narrative moment than a raw test of mechanical skill. However, underestimating her, and you'll find her stash of silk threads and crushing pins adequate to shorten a reckless dash.

Here, within this guide, we're going to walk you through preparing for the fight, breaking down the Grand Mother Silk phases, looking into her attack mechanics, and identifying the best tactics to make you the winner.

Preparing for the Fight

The encounter with Hollow Knight Silksong Grand Mother Silk takes place in the Terminus, the final stretch of the game. By this point, you’ll hopefully have upgraded your Needle at least twice or three times. If you’ve been exploring thoroughly, you’ll also have access to powerful tools and crests that can make the fight much easier.

At a minimum, you’ll want:

• Some Needle upgrades, preferably the Pale Oils from the Citadel and Pharloom Wish quest.
• Some good Tools to suit your play style. Blue Tools like the Fractured Mask (which gives you a second life) or the Injector Band (for faster healing) are worth their ounce of gold.
• Red Tools like the Cogfly in tandem with the Pollip Pouch, which deal poison damage and chip away at Grand Mother Silk's enormous health pool as you focus on dodging. From a loadout viewpoint, the Crest of the Wanderer is a great choice to speed up your attacks, and the Weighted Belt steadies Hornet so that you cannot be knocked back mid-swing. Assuming you've upgraded your crafting kit to the maximum, your Cogflies will chew through her health bar while you're staying on the move. Finally, the back run to the arena is mercifully short. From the Terminus bench, it's roughly half a minute to walk up the platforms, climb the left wall, and reach the boss chamber. Compared to some of Silksong's more sadistic runs, this one is very forgiving.

Phase One: The Dance of Pins

The fight begins with Grandmother Silk standing in the center of the arena. As soon as she comes out, her six humongous pins snap into play, their attack patterns set so that they drive you into the corners. This is a positioning and anticipation phase of the Grand Mother Silk. Her most common move is the Six Pin Skewer, where needles emitting radiant fire in from the sides or the ceiling. The side attacks are harder to dodge, but the trick is the same each time: find the gap and dash or float through. Hornet's Clawline skill is a blessing in this situation, enabling you to zip across the arena or thread the air between attacks. The Sweeping Slash is another familiar move. Grandmother Silk sweeps across the stage, claws aloft, as her pins descend in a rain from above. It's not too hard to get pinned in if you do get surprised, but the best thing to do is remain on the wall of the arena until she is beyond range. Jumping over her sweep is also an option, but never mind keeping an eye out for pins dropping down from above.

Her most dangerous first act is Thread the Needle, a thread-by-thread mesh of silk threads in a lethal cross-cross. If caught, Hornet is fixed and sustains massive damage. The solution is to remain calm. Don't panic, run into the threads. Rather, remain stationary in secure locations, and when necessary, jump once or twice to hover above in an open space until the attack ceases. With all these habits, your job is to keep pressure consistent. You'll mostly be hitting her stomach, so you have to fight while airborne. Try to chain multiple aerials together, and use your Clawline to come back after each attack. The more comfortable you get with hovering, the more enjoyable this stage will be.

Phase Two: Heavier, Faster, Deadlier

After having sustained enough damage, Grandmother Silk lets out a blood-curdling shriek and pulls herself beneath the arena. Boulders descend from the arena's top, signaling the start of the second of the Grand Mother Silk phases. This is your cue to sprint out of danger, summon Cogflies or equip equipment, and ready yourself for the second part of the fight, which will be faster and more intense. Phase Two retains the fundamentals, but every attack comes in more quickly, and she introduces some new tactics. Thread the Needle likes to show up immediately after phase transition, catching players who attempt to jump in too quickly. Always stay on your toes and be ready to fall back until you see her pattern start to emerge. Ground Spikes is a new move during this phase. Silk threads stretch out on the ground, then turn up in jagged spiked platforms, the same type you would have pogoed through previously in Pharloom. The ground is patchy and treacherous, so you will need to pogo on the spikes or run hazardously across the gaps. This is where your air battle skills pay off, since flying keeps you over the danger and enables you to strike at her exposed body. She also makes more use of the Rock Slide attack, dropping loose pieces of ceiling on top of the arena. Fortunately, this is also one of her less complicated moves to avoid, as long as you keep moving and watch for falling dust as an early indicator. What's frightening about Phase Two isn't so much the complexity of her attacks, but the pace. With less space to breathe, you'll be healing opportunistically, usually after dodging a pin strike or after she sweeps. That's also where your Red Tools shine. Poison Cogflies or Flea Brew damage stacks quickly, so you can chip her down without needing to stay dangerously close.

The Final Blow

Grand Mother Silk doesn’t have as many phases as some of Silksong’s other climactic bosses, but her second phase lasts long enough to push your resource management. Once you’ve weathered her faster attacks, dodged her pins, and used the arena’s verticality to your advantage, she will finally collapse. At this point, you’ll be prompted to bind her with your Needle, consuming her silk essence. A cutscene follows, one that hints strongly that this is not the true final ending of the game. But whether or not Silksong has more surprises waiting, taking down Grand Mother Silk Silksong is a satisfying milestone and one of the most cinematic battles in Hornet’s journey.

Final Thoughts

The fight with Hollow Knight Silksong Grand Mother Silk is a dance of strategy and spectacle. It's not quite so single-brutally punishing as a couple of the optional battles, but it needs you to stay focused, learn about aerial positioning, and keep track of several threats at the same time. By the time you meet her, you'll have everything you need; it's merely a matter of getting it down smoothly. Her two disparate phases, from the rhythmic thuds of her glinting pins to the uncontrolled rockfalls and silk spikes of her final attack, maintain the battle at a cliffhanger without dragging on. And while she might not be the game's most difficult boss, she is one of its most memorable ones, tying up loose ends on your journey into a satisfying climax.
