Complete breakdown of LoL Patch 13.20 with strategic insights for adapting to jungle nerfs and champion changes

Patch 13.20 Overview and Release Schedule

League of Legends enthusiasts are preparing for substantial gameplay shifts with the arrival of Patch 13.20, featuring transformative adjustments across multiple systems. This update delivers a comprehensive rework for K’Sante alongside significant modifications to jungle dynamics and rune effectiveness.

Patch 13.20 introduces experimental preseason preparations including K’Sante’s professional-play-focused rework, jungle role power reduction, and widespread rune adjustments that will reshape the current meta landscape.

Following the stabilization of Patch 13.19 for Worlds 2023, Riot Games is implementing bold changes to refresh gameplay dynamics. The development team aims to address balance concerns while preparing systems for upcoming preseason transitions, making this a crucial transitional patch for competitive and casual players alike.

Mark your calendars for October 11, 2023 as Patch 13.20 begins its global deployment according to Riot’s established schedule. The update will initially reach Oceanic servers before progressively rolling out to other regions throughout the day.

Server maintenance typically commences several hours before patch activation, with matchmaking queues disabled approximately three hours prior to ensure smooth transition. Players should anticipate temporary service interruptions during the update process.

Champion Balance Updates and K’Sante Rework

K’Sante undergoes a substantial gameplay overhaul in Patch 13.20 designed to preserve his engaging playstyle while reducing his overwhelming presence in professional competitions. The rework maintains his fundamental abilities but dramatically alters their interactions and scaling mechanics.

Passive: Death in Lavender

  • Bonus attack speed reduced: 25 – 50% (based on linear level scaling) >>> 20 – 40% (based on stat progression multiplier)
  • Damage reduction reduced: 70% at all ranks >>> 42/49/56/63/70%
  • Minimum base damage per hit reduced: 8/10/12/14/16 >>> 6/7/8/9/10
  • Minimum AD ratio per hit increased: 6% >>> 8%
  • Can now critically strike
  • Remora health changed: 40/50/60% >>> 20/45/70%
  • Cooldown: 18/17.5/17/16.5/16 >>> 18/17/16/15/14
  • Shield out of combat timer: 12 seconds flat >>> 12/11/8 (levels 1/6/11)
  • Health growth increased: 100 >>> 105

    • Passive: Get Excited!

  • Bonus attack speed now stacks upon takedowns.

    • R: Super Mega Death Rocket

  • Cooldown reduced: 75-55 >>> 70-40 seconds
  • Minimum damage: 30/45/60 (+15% bonus AD) >>> 32.5/47.5/62.5 (+16.5% bonus AD)
  • Maxiumu damage: 300/450/600 (+150% bonus AD) 325/475/625 (+165% bonus AD)

    • Several other champions receive targeted adjustments to address balance outliers. Jinx gains stacking attack speed on her passive and reduced ultimate cooldown, enhancing her teamfight cleanup potential. Multiple mages and fighters receive stat adjustments to better align with current power curves.

    Strategic Insight: K’Sante players should focus on adapting to his new damage profile, leveraging critical strike opportunities while managing his reduced early-game durability. The changes reward precise ability sequencing and strategic engagement timing rather than raw stat dominance.

    Jungle System Nerfs and Strategic Implications

    The jungle position has maintained excessive influence for multiple seasons, prompting Riot to implement systematic power reduction while preserving the role’s engaging mechanics. These adjustments target economic advantages and late-game scaling without diminishing the core jungle experience.

    Companion pets undergo significant nerfs across all specializations:

  • Gustwalker
    • Brush movement speed increase: 45% >>> 30%
    • Large monster kill movement speed increase: 60% >>> 45%
  • Mossstomper
    • 60-281 (levels 1-18) >>> 180-300 (levels 10-18)
    • Shield no longer grants tenacity and slow resist
  • Scorchclaw
    • No longer procs from Smite, requires damage from a spell or basic attack

    • Jungle camp health scaling receives substantial adjustments, making late-game clearing significantly more demanding:

  • Blue Sentinel Health: 2300 – 4600 (levels 1-11) >>> 2300 – 6210 (levels 1-18)
  • Red Brambleback Health: 2300 – 4600 (levels 1-11) >>> 2300 – 6210 (levels 1-18)
  • Sir Gromp Health: 2050 – 4100 (levels 1-11) >>> 2050 – 4817.5 (levels 1-18)
  • Crimson Raptor Health: 1100 – 2585 (levels 1-11) 1200 – 2820 (levels 1-18)
  • Raptors Health: 500 – 1000 (levels 1-11) ; 500 – 1175 (levels 1-18)
  • Greater Murk Wolf Health: 1600 – 3200 (levels 1-11) ; 1600 – 3760 (levels 1-18)
  • Murk Wolves Health: 630 – 1260 (levels 1-11) ; 630 – 1480.5 (levels 1-18)
  • Ancient Krug Health: 1350 – 2700 (levels 1-11) ; 1350 – 3172.5 (levels 1-18)

    • Smite functionality receives quality-of-life improvements and balance adjustments:

  • Damage to Champions/Pets: 20-160 (levels 1-18) >>> 40 flat
  • [NEW] Smite Epic Monster Forgiveness: Smite now has 350 units of targeting forgiveness against Epic Monsters. This means if your cursor is near their model but not on top of another valid target it will act as though you are targeting them.
  • Primal Smite AoE Damage when Smiting Monsters: 50% of Smite’s damage >>> 100% of Smite’s damage
  • Junglers with Primal Smite no longer take 20% less damage from epic monsters when two or more allies are nearby.

    • Strategic Impact: Jungle pathing efficiency becomes more crucial than ever. Players should prioritize optimal clearing routes and consider champion selections with inherent camp-clearing advantages. The reduced mobility from Gustwalker nerfs makes efficient pathing essential for maintaining map presence.

    Common Mistake: Attempting to maintain previous clear speeds without adjusting for increased camp health will result in health and tempo deficits. Adapt your jungle route to account for longer clear times in the mid to late game.

    Epic Monster and Objective Changes

    Dragon stacking strategies receive significant nerfs to curb snowball potential, making early dragon prioritization less dominant. Individual dragon stat bonuses are reduced across all elements while soul power receives slight enhancements for late-game relevance.

  • 7% slow resistance and out-of-combat movement speed >>> 5% slow resistance and out-of-combat movement speed
  • 7.5 ability haste and 7.5% bonus attack speed >>> 5 ability haste and 5% bonus attack speed
  • 5% attack damage and ability power >>> 3% attack damage and ability power
  • 8% bonus armor and magic resistance >>> 5% bonus armor and magic resistance
  • restore 2.5% missing health every 5 seconds >>> restore 2% missing health every 5 seconds

    • Dragon soul enhancements provide increased late-game power:

  • 15% bonus movement speed >>> 20% bonus movement speed
  • 40% base slow (30% for ranged) >>> 45% base slow (35% for ranged)
  • 80 adaptive damage for explosion >>> 100 adaptive damage for explosion
  • 180 base shield >>> 220 base shield
  • 130 base heal, 80 base mana regen >>> 150 base heal, 100 base mana regen

    • Baron Nashor receives substantial durability increases and death timer adjustments:

  • Local gold given: 200 >>> 100
  • Base Health: 12600 >>> 15000
  • Level 1 Death Timer: Unchanged
  • Level 2 Death Timer: 8 seconds ; 6 seconds
  • Level 3 Death Timer: 10 seconds ; 8 seconds
  • Level 4 Death Timer: 12 seconds ; 8 seconds
  • Level 5 Death Timer: 14 seconds ; 10 seconds
  • Level 6 Death Timer: 16 seconds ; 12 seconds
  • Level 7 Death Timer: 21 seconds ; 16 seconds
  • Level 8 Death Timer: 27.5 seconds ; 21 seconds
  • Level 9 Death Timer: 30 seconds ; 26 seconds
  • Gold per plate: 175 >>> 125

    • Strategic Insight: Teams should reconsider early dragon priority and explore alternative win conditions through Herald plays and top-side pressure. The changes encourage more diversified objective strategies rather than defaulting to dragon stacking.

    Rune System Rebalancing

    Patch 13.20 delivers substantial nerfs to many dominant runes that have shaped the current meta. These adjustments target both early game dominance and scaling potential across multiple keystone and secondary runes.

  • Adaptive Damage: 30-100 (based on level) (+35% bonus AD) (+20% AP) >>> 30-130 (based on level) (+10% bonus AD) (+5% AP)
  • Attack Damage per Stack: 1.2 – 2.7 (based on level) bonus AD >>> 1.08 – 2.4 (based on level) bonus AD
  • Ability Power per Stack: 2 – 4.5 (based on level) AP >>> 1.8 – 2.4 (based on level) AP
  • Attack Damage at Maximum Stacks: 14.4 – 32.4 (based on level) bonus AD >>> 12.96 – 28.8 (based on level) bonus AD
  • Ability Power at Maximum Stacks: 24 – 54 (based on level) bonus AP >>> 21.6 – 48 (based on level) bonus AP
  • Adaptive Damage: 20-60 (based on level) (+ 5 per Soul) (+25% bonus AD) (+15% AP) >>> 20-80 (based on level) (+ 5 per Soul) (+10% bonus AD) (+5% AP)
  • Damage: 30-180 (based on level) (+40% bonus AD) (+25% AP) >>> 30-220 (based on level) (+10% bonus AD) (+5% AP)
  • Bonus True Damage: 9% >>> 8%
  • Heal: 10-100 (based on level) (+30% bonus AD) (+20% AP) >>> 10-130 (based on level) (+10% bonus AD) (+5% AP)
  • Attack Speed per Stack (Melee): 10 – 15% >>> 9 – 13.5%
  • Attack Speed per Stack (Ranged): 4 – 9% >>> 3.6 – 8%
  • Adaptive Damage: 10-40 (based on level) (+15% bonus AD) (+10% AP) >>> 10-50 (based on level) (+10% bonus AD) (+5% AP)
  • Shield: 30-75 (based on level) (+35% bonus AD) (+22.5% AP) >>> 30-100 (based on level) (+10% bonus AD) (+5% AP)
  • Healing: 16-30 (based on level) (+15% bonus AD) (+8% AP) >>> 16-40 (based on level) (+10% bonus AD) (+5% AP)
  • Adaptive Force: 5-30 (based on level) >>> 13-30 (based on level)
  • Movement Speed: 25 >>> 10

    • Optimization Tip: Players should experiment with previously underutilized runes that may become more viable following these nerfs. Consider runes that provide consistent value throughout the game rather than early-game dominance.

    Advanced Strategy: The changes to scaling ratios make itemization choices more critical than ever. Build paths that complement your chosen runes’ strengths while compensating for their reduced statistical output.
