League of Legends patch 13.8 notes: junglers buffed, Aurelion Sol nerfed ahead of MSI

Complete guide to LoL Patch 13.8: MSI preparation changes, champion adjustments and strategic insights

Patch 13.8 Overview: MSI Preparation Phase

League of Legends Patch 13.8 introduces crucial balance adjustments designed to shape the competitive landscape for the Mid-Season Invitational. This update strategically enhances niche jungle specialists while reigning in dominant solo queue performers that have been warping the meta.

With the Mid-Season Invitational rapidly approaching, Riot Games is delivering their final competitive tuning before the international tournament locks in. Patch 13.8 represents the definitive version that professional teams will compete on during MSI, making these adjustments critically important for the global competitive scene.

According to Lead Designer Riot Phroxzon, the current meta demonstrates strong overall health, prompting targeted rather than sweeping changes. The development team is specifically focusing on elevating underutilized jungle champions while addressing solo queue outliers that create disproportionate impact.

League of Legends Patch 13.8 deployment begins on April 19, 2023, following Riot’s established update schedule. The rollout initiates on Oceanic servers with global deployment following throughout the day. Players should anticipate several hours of server downtime during the patching process.

Matchmaking queues will be disabled approximately three hours before maintenance commences. Strategic players should plan their gaming sessions accordingly to avoid interrupted matches during the transition period.

Champion Balance Changes: Buffs, Nerfs and Meta Shifts

Aurelion Sol’s dominance receives targeted nerfs following his gameplay rework, while jungle specialists Nidalee and Lillia gain competitive enhancements. These changes aim to diversify professional play options while maintaining balanced solo queue experiences.

Aurelion Sol has been completely reshaping competitive and casual play since his comprehensive ability overhaul earlier this season. Maintaining a robust 50.45% win rate according to u.gg statistics, the celestial dragon has become a priority pick across multiple skill levels. Riot’s adjustments in Patch 13.8 specifically target his scaling capabilities and late-game impact.

Jungle meta adjustments introduce meaningful buffs to Nidalee and Lillia, two champions with high skill ceilings that can dominate games in experienced hands. These changes aim to increase their presence during MSI while providing professional junglers with additional strategic options. The buffs focus on improving their jungle clear efficiency and mid-game power spikes.

Kog’Maw receives significant quality-of-life improvements to his passive ability Icathian Surprise, now providing Ghosted status during his post-death form. This prevents unit collision during his explosive finale, potentially increasing his passive damage effectiveness in crowded teamfights.

Systemic changes include new movement speed mechanics that reward consistent champion engagement. Damaging enemy champions now generates stacking movement speed bonuses, creating new kiting and positioning opportunities for skilled players.

Strategic Analysis and Gameplay Implications

Patch 13.8 creates new strategic opportunities while addressing common adaptation pitfalls. Understanding these meta shifts is crucial for maintaining competitive performance during the MSI competitive season.

Practical Tips and Strategies: The Nidalee buffs significantly improve her early jungle clear speed. Prioritize maxing Javelin Toss first to leverage the increased base damage and AP ratio. For Lillia, the enhanced monster damage cap means you can clear camps more efficiently while maintaining healthier throughout the process. Aurelion Sol players should adjust their scaling expectations and focus more on mid-game power spikes rather than late-game dominance.

Common Mistakes and Avoidance: Many players incorrectly assume the Aurelion Sol nerfs make him unplayable. While his late-game scaling is reduced, his mid-game teamfight presence remains substantial. Another frequent error involves overestimating Kog’Maw’s passive changes—while the Ghosted effect is useful, it doesn’t compensate for poor positioning during living gameplay. Jungle players often misjudge the timing windows for Nidalee and Lillia’s power spikes post-buff.

Advanced Optimization: High-level players should experiment with the new movement speed stacking mechanics to create innovative kiting patterns. The consistent damage requirement for maintaining stacks rewards champions with persistent damage abilities. Consider pairing these changes with items like Cosmic Drive for maximum mobility advantages. For competitive play, the jungle buffs open up new early game invasion opportunities, particularly with Nidalee’s enhanced spear damage.
