Is this Lee Sin kick interaction a bug? Jarvan IV players hope so

TL;DR

  • Lee Sin’s ultimate creates unintended knockup effects when timed against Jarvan’s dash
  • The bug allows Jarvan to complete his E+Q while triggering Dragon’s Rage knockup on allies
  • Pro player RoseThorn demonstrated this interaction in LCS Proving Grounds
  • Jarvan players must adjust timing or risk devastating teamfight consequences
  • Both champions require awareness of this timing-specific mechanical conflict

A startling mechanical anomaly between Lee Sin and Jarvan IV has emerged as one of League’s most perplexing recent interactions, catching both professional players and developers by surprise.

Riot Games’ flagship MOBA frequently showcases unexpected ability combinations, but this particular clash of mechanics transforms what should be Jarvan’s reliable escape tool into a potential teamfight catastrophe. The interaction gained notoriety after appearing in competitive play, leaving analysts scrambling to understand the implications.

What makes this bug particularly dangerous is its timing-dependent nature—occurring only when abilities are activated within milliseconds of each other, creating outcomes that defy standard game logic.

Lee Sin’s ultimate ability, “Dragon’s Rage,” stands as one of League’s most potent displacement tools, capable of single-handedly reshaping teamfight dynamics. The skill functions by launching a targeted enemy champion backward, forcibly repositioning them while dealing significant physical damage.

A critical advanced technique involves buffering Flash during the ultimate’s cast animation, allowing skilled players to alter the kick’s direction unexpectedly. This flash-kick combination separates elite Lee Sin players from average ones, enabling creative outplays and unexpected engages.

The secondary mechanic—knocking up other champions the target passes through—creates area denial and sets up additional crowd control chains. Understanding this knockup property is essential to comprehending the bug’s full impact.

Jarvan IV’s fundamental engagement tool combines his Demacian Standard (E) with Dragon Strike (Q), creating a targeted dash toward the flag’s location. This maneuver serves multiple purposes: gap closing, escape mechanism, and initiation tool depending on situational context.

Standard execution involves placing the Demacian Standard followed immediately by Dragon Strike, propelling Jarvan toward the flag while knocking up enemies along his path. The dash follows a predictable trajectory and typically respects crowd control interactions as expected.

However, when this dash initiation coincides perfectly with Lee Sin’s ultimate activation, the game’s internal mechanics struggle to resolve the conflicting inputs, resulting in bizarre behavioral outcomes.

The core issue emerges from what appears to be a desynchronization between visual effects and mechanical resolution. When Jarvan begins his E+Q dash milliseconds before Lee Sin’s Dragon’s Rage connects, two conflicting game states occur simultaneously.

Jarvan visually completes his intended dash path to the Demacian Standard, seemingly ignoring the displacement force that should redirect his trajectory. Meanwhile, the game’s underlying mechanics still process Lee Sin’s ultimate, applying its knockup effect to any allies Jarvan passes over during his travel.

This creates a paradoxical situation where Jarvan benefits from completing his escape while inadvertently damaging and crowd controlling his own teammates. The visual disconnect makes the interaction particularly confusing for players observing the sequence.

Understanding the precise 50-100 millisecond timing window is crucial for both avoiding and exploiting this bug effectively.

This mechanical anomaly first gained widespread attention during the LCS Proving Grounds tournament, a competitive platform designed to cultivate emerging North American talent. The high-stakes environment magnified the bug’s impact, turning what should have been a routine engagement into a match-defining moment.

Professional player Tae-ho “RoseThorn” Kim executed what appeared to be a standard Lee Sin ultimate on an enemy Jarvan IV. However, the Jarvan player activated his E+Q combination at the perfect moment to trigger the bug.

The resulting sequence saw Jarvan successfully dash to his flag while simultaneously knocking up and damaging his allied Vayne and Sett champions. This unintended friendly fire resulted in Sett’s elimination and essentially decided the teamfight outcome.

Immediate spectator reaction reflected widespread confusion, with many initially attributing the outcome to exceptional play rather than mechanical failure.

For Jarvan players facing Lee Sin opponents, this interaction introduces significant risk to what should be reliable escape patterns. The recommended counterplay involves either delaying E+Q activation until after Dragon’s Rage completes or utilizing alternative escape routes that avoid passing over allied champions.

Lee Sin players can potentially exploit this timing by anticipating Jarvan’s dash attempts and activating Dragon’s Rage accordingly. However, this requires precise prediction and carries its own risks if mistimed.

Both champions maintain high jungle popularity, making this matchup knowledge essential for competitive play. Jarvan already struggles in this pairing, and this bug further exacerbates the disadvantage.

Strategic awareness becomes particularly crucial in late-game scenarios where single teamfight outcomes often determine match results. Teams must adjust their positioning and ability timing to mitigate this unpredictable element.

As with any complex game mechanics, understanding these interactions separates average players from truly exceptional ones who can adapt to unexpected circumstances.

Action Checklist

  • Monitor ability cooldowns and anticipate dash timing in this matchup
  • As Jarvan, avoid using E+Q when low health allies are positioned behind you
  • Practice alternative escape routes that don’t pass through team formations
  • As Lee Sin, time ultimates to catch Jarvan during dash startup frames
  • Communicate this interaction to teammates during champion select and loading screen
