Hollow Knight: Silksong Boss Fight Trivialized by Simple Upslash Glitch

In the ever-evolving landscape of gaming, where intricate mechanics and challenging encounters define the experience, discoveries that shift the paradigm are always exciting. As Digital Tech Explorer aims to bring you the cutting edge of tech and gaming insights, we delve into a fascinating exploit within Hollow Knight: Silksong. One of the game’s late-game boss fights can be entirely circumvented, allowing players to defeat the formidable adversary without engaging in a true battle. This is made possible by a newly discovered glitch that essentially causes the boss to “turn off” and accept defeat, a true testament to the sometimes-unpredictable nature of game design.

Uncovered by a diligent member of the Silksong speedrunning Discord community and brilliantly showcased by YouTuber Kilroy Was Here, a consistent and remarkably simple method has emerged to trivialize one of the toughest encounters in the game’s second act. This exploit, a highlight for any tech enthusiast, requires precise movement and cleverly leverages a rather unusual in-game mechanic, turning a seemingly insurmountable challenge into an intriguing puzzle to solve.

How to Perform the Upslash AI Break Glitch

The core of this ingenious trick, dubbed an “upslash AI break” by Kilroy, involves repeatedly swiping upward with Hornet’s needle. For reasons still not fully understood by the community, this specific action causes the formidable boss, Lace (during her second encounter near the end of the game), to freeze completely in place. Once immobilized, she passively accepts each hit until her health bar is entirely depleted, transforming a fierce duel into a methodical takedown.

Executing this Lace boss glitch doesn’t demand any specific crests or specialized tools, making it accessible to many players. The primary challenge lies in accurately positioning Hornet close enough to Lace to land hits without incurring damage yourself. However, once Lace is “locked in” by the continuous upswipes, she ceases all movement, allowing for uninterrupted attacks. Players only need to quickly re-align themselves if Lace is occasionally knocked backward towards the edge of the platform. From this vantage, she can be continuously struck until she falls off, suffering significant damage. Upon her reappearance on the opposing side, she will be merely a few hits away from total defeat, simplifying one of Silksong’s most challenging encounters.

The Glitch’s Specificity and Impact

Typically, the second confrontation with Lace is defined by her aggressive and remarkably agile movements. Dashing across the arena and delivering blows that inflict two points of damage, she presents a truly challenging duel. This upslash AI break completely negates that inherent difficulty, transforming what was a complex, high-stakes fight into a surprisingly simple sequence of attacks. It’s a prime example of how a singular mechanic can utterly redefine an established challenge.

The precise mechanics that compel an upward attack to cause Lace to freeze remain an enigma. Extensive testing, including attempts on a similar Act 3 boss, has confirmed that this particular exploit is specific to Lace. It does not work on other bosses, many of whom teleport too frequently or possess different AI patterns that render the trick ineffective. This limitation means this particular Hollow Knight: Silksong glitch is tied exclusively to this one specific boss fight, adding to its unique charm and mystique.

Beyond simply bypassing a tough fight, this glitch proves to be exceptionally efficient for speedrunning Silksong. Kilroy impressively demonstrated taking out Lace in approximately 35 seconds, a time that, at the video’s release, was faster than the existing speedrun world record holder’s fight. Should this trick be deemed permissible in competitive speedrunning, Lace faces continued humiliation until Team Cherry releases a patch to address this intriguing vulnerability, further highlighting the dynamic interplay between game design and player ingenuity.

As TechTalesLeo loves to explore, this unique AI manipulation strategy offers players an unexpected, engaging way to bypass a tough challenge. It brilliantly highlights the intricate, sometimes exploitable, nature of game design, offering both a practical shortcut for players and a fascinating insight for tech enthusiasts and developers alike.
