League of Legends patch 25.18 launched on September 10, 2025, bringing significant balance changes alongside the highly anticipated T1 Worlds 24 skins. This update focuses on reigning in overpowered champions while enhancing underperforming picks, creating a more diverse competitive landscape. The most impactful adjustments target Yunara’s recent dominance and address jungle Sylas’s excessive clearing efficiency.

Strategic players should note that this patch introduces both numerical tweaks and fundamental gameplay adjustments. Understanding these changes is crucial for adapting your champion pool and playstyle to maintain competitive advantage. The modifications span across multiple roles, affecting early game junglers, scaling mages, and several popular top lane picks.

Champion Nerfs: Power Level Reductions

High-priority targets receiving direct nerfs include Yunara, Qiyana, and Sylas in the jungle role. These champions have demonstrated excessive win rates in high elo and professional play, necessitating adjustments to restore balance.

  • Cooldown: 16 / 15.5 / 15 / 14.5 / 14 ⇒ 16 / 15 / 14 / 13 / 12 seconds
  • Mana Cost: 45 / 50 / 55 / 60 / 65 ⇒ 50 at all ranks
  • Yunara’s early game pressure receives a noticeable hit with increased mana costs and adjusted cooldown progression. This forces players to manage resources more carefully during laning phase and reduces her ability to spam abilities for wave clear and poke.

  • AD Growth: 2.95 ⇒ 3.45
  • Base Damage vs Poisoned Targets: 20 / 40 / 60 / 80 / 100 ⇒ 20 / 43 / 66 / 89 / 112
  • AD Ratio per Spin: 36 / 39 / 42 / 45 / 48% AD ⇒ 38 / 41 / 44 / 47 / 50% AD
  • Twisted Fate receives mixed adjustments that shift power toward later stages of the game. While his AD growth improves significantly, the restructured damage progression requires players to reach higher levels before achieving previous power spikes.

  • Base Bonus Movement Speed: 20 / 22.5 / 25 / 27.5 / 30% ⇒ 30 / 32.5 / 35 / 37.5 / 40%
  • Bonus Movement Speed AP Ratio: +2% per 100 AP ⇒ +3% per 100 AP
  • Jungle Sylas faces substantial nerfs to his clearing efficiency and ganking potential. The reduced bonus damage to monsters significantly impacts his early jungle clear speed, while movement speed duration standardization limits his mobility during ganks.

  • Bonus Damage to Monsters: 150% ⇒ 130%
  • Movement Speed Duration: 1.5 / 1.75 / 2 / 2.25 / 2.5 ⇒ 1.5 seconds at all ranks
  • Common mistake to avoid: Continuing to play these nerfed champions with pre-patch strategies will lead to suboptimal performance. Adjust your playstyle to accommodate their new limitations, particularly regarding resource management and power spikes.

    Champion Adjustments: Balance Shifts

    Several champions receive targeted buffs aimed at improving their viability without creating new balance issues. AP champions particularly benefit from these adjustments, with multiple mages receiving ratio improvements.

  • EQ – Grim Visage AP Ratio: 60% ⇒ 65%
  • EW – Gaze of the Abyss AP Ratio: 60% ⇒ 65%
  • EE – Crushing Maw AP Ratio: 60% ⇒ 65%
  • Fiddlesticks gains consistent AP ratio buffs across all basic abilities, significantly improving his late-game scaling. This makes building AP items more rewarding and increases his threat level in team fights.

  • Damage: 60 / 110 / 160 / 210 / 260 / 310 ⇒ 80 / 126 / 172 / 218 / 264 / 310
  • Cooldown: 14 / 13.5 / 13 / 12.5 / 12 ⇒ 12 / 11.5 / 11 / 10.5 / 10 seconds
  • Kai’Sa’s evolution requirements become more accessible with these changes, allowing players to reach critical power spikes earlier in the game. The cooldown reduction provides additional uptime for her mobility tool.

  • Bugfix: Fixed a bug where Briar would sometimes stop moving and lose her attack command when Frenzy expired
  • QoL Change: No longer spawns tentacles during Summoner Teleport. Her passive now waits until she’s done teleporting.
  • Critical bug fixes address frustrating gameplay issues that have plagued Briar and Illaoi players. These quality of life improvements significantly enhance gameplay smoothness and reliability.

  • Global Sound: Plays on cast ⇒ Plays after cast
  • Going Ghost: Now grants Ghosting during ultimate.
  • Optimization tip: Take advantage of the AP ratio buffs by prioritizing ability power items on affected champions. The increased scaling makes these picks more threatening in extended fights and late-game scenarios.

    System and Item Changes

    Item adjustments in patch 25.18 target both statistical values and functional mechanics, creating new build paths and strategic considerations.

  • Magic Penetration: 15 / 17.5 / 20% ⇒ 10 / 15 / 20%
  • Base Percent Max Health Damage: 2.5% ⇒ 1%
  • Percent Max Health Damage AP Ratio: 2% per 100 AP ⇒ 2.7% per 100 AP
  • Liandry’s Anguish undergoes significant restructuring, with reduced base damage but improved AP scaling. This shift rewards dedicated mage builds while reducing the item’s effectiveness on hybrid or tank champions.

  • Attack Damage: 40 ⇒ 50
  • Magic Resistance: 40 ⇒ 35
  • Active Movespeed Duration: 1.5 ⇒ 2 seconds
  • Statikk Shiv receives offensive buffs that increase its wave clear potential and dueling power. The extended movement speed duration provides additional utility for positioning and escaping dangerous situations.

  • Percent Amp on Monsters: 50% ⇒ 100%
  • Percent Amp on Minions and Monsters: 50% ⇒ 60%
  • Jungle-specific adjustments improve clearing efficiency for certain champions while maintaining balance across the role. These changes help standardize jungle clear times and create more consistent early game patterns.

    Practical strategy: Re-evaluate your core build paths considering these item changes. Liandry’s now favors high-AP builds, while Statikk Shiv becomes more attractive for champions needing wave clear and mobility.

    Strategic Analysis and Meta Impact

    Patch 25.18 creates substantial shifts in the competitive meta, particularly affecting jungle priorities and mid lane matchups. Understanding these changes is essential for maintaining rank advancement and competitive performance.

    The nerfs to Yunara and jungle Sylas open opportunities for alternative picks to rise in priority. Champions that previously struggled against these dominant picks may now see improved win rates and pick rates.

    AP champion buffs significantly impact late-game team compositions. Mages with improved scaling become more valuable in extended matches, shifting draft priorities toward protecting scaling carries and enabling their late-game potential.

    Jungle pathing and clearing strategies require adjustment due to the monster damage modifications. Efficient clears become more important as champion-specific jungle buffs and nerfs change clear speed differentials.

    Advanced optimization: Track win rate changes daily during the first week post-patch to identify emerging strong picks before they become widely recognized. Early adaptation to meta shifts provides significant competitive advantage.

    That’s everything featured in the release notes for League of Legends patch 25.18.
