League of Legends patch 13.17 pre-notes are now live, and Riot Games has provided a fair bit of information on what to expect from the update, which is set to go live next week. Patch 13.17 will be one of the major balance updates before heading into Worlds 2023, so it’s not surprising that there are a lot of tweaks this time around.When talking about League of Legends patch 13.17, Riot Games stated:“We're continuing to move Xerath/Lux into mid. Fighter item changes add durability to these champions to allow them to soak damage a bit more, rather than one shot people more.”The developer continued:“In Preseason, we adjusted catchup XP to trigger when down 2 levels rounding up to be more forgiving [eg. 1.4 round to 2], but had some negative consequences around encouraging too much ganking and optimizing the mechanic actively more than we'd like (esp edge case of 1.1 to 2)”League of Legends patch 13.17 pre-notesBefore moving on to the list of changes, it’s important to note that Riot Games will first try out these changes in the League of Legends PBE before shipping them with the official update next week. Hence, the tweaks mentioned are tentative and may not reflect in the official 13.17 patch.1) Champion BuffsEliseAA Damage: 10/20/30/40 (+20% AP) >>> 12/22/32/42 (+20% AP)AA Healing: 4/6/8/10 (+8% AP) >>> 6/8/10/12 (+8% AP)E Stun Duration: 16/17/1.8/1.9/2s >>> 16/1.8/2/2:2/2.45Gnar Mega Q Base Damage: 25-205 >>> 45225Mega W Base Damage: 25-145 >>> 35-155Lux Mid Mana Regen: 8 >>> 7P Damage: 20-190 (+20% AP) >>> 30-200 (+25% AP)Q Cooldown: Hs (at all ranks) >>> HA0.5/10/9.5/9s (ranks 15)E Damage: 70-270 (+80% AP) >>> 65-265 (180% AP)Orianna Health Growth: 105 >>> 110W Damage: 60/105 / 150/195 / 240 (+ 70% AP) >>> 70/120 / 170 / 220/ 270Samira Health: 600 >>> 630Twisted Fate Q AP Ratio: 80% >>> 90%Tryndamere Attack Range: 125 >>> 175Q Damage: 60/105 / 150/195 / 240 (+ 70% AP) >>> 70 / 115/160 / 205 / 250 (+ 70% AP)Vex W Cooldown: 20/18 /16 /14/12 >>> 16/15 /14./ 13 / 12.R ping now mentions any enemies that are in range of itZoe HP Regen: 6.5 >>> 7.5 — E Sleep Duration: 2.255 >>> 2.55E Magic Resistance Reduction: 20 / 22.5 / 25 / 275 / 30% >> 30%2) Champion NerfsKaynW AD Ratio: 1.3 >>> 1.1Kha'zix Q AD Ratio: 115 >>> 11Kindred E Slow: 50% >>> 30%E Missing HP Damage: 8% + 0.5% per mark >>> 5% + 0.5% per markNaafiriBase Health: 650 >> 635Passive CD: 25-10 based on level >>> 30-15 based on levelNEW - Packmates take 100% bonus damage from champion melee attacksNaafir Q2 Heal: 45/65/85/105/125 + 40%bAD >>> 45/60/75/90/105 + 40% bADQ2 min damage: 35/50/65/80/95 + 70% bAD >>> 30/45/60/75/90 + 40% bADQ2 max damage: 70/100/130/160/190 +140% bAD >>> 60/90/100/130/180 + 140% bADE First Hit Ratio: 60% bAD >>50% bADE Second Hit Ratio 90 bAD >> 80% bADXerath Support Base Mana Regen: 8 >>> 6.85P Unit Kill CD Restore: 2s >>> 2.55W Mana Cost: 70-110 >>> 80-1203) Champion AdjustmentsAatrox Passive and W now deal Magic Damage:Akshan Health Growth: 104 >>> 107Armor Growth: 4.2 >>> 47Attack Damage Growth: 3.5 >>> 3.0BlitzcrankHealth: 633 > 650MR: 28 >32 Base AS: 065> 0.625AS Ratio: 07 > 0.625P Shield: 15-45% > 30%W Mana Cost: 85>75W AS: 30/43/56/69/82 > 30/40/50/60/70W no longer grants Bonus magic damage on hitE Mana cost: 40 >25E AD Ratio: 75% >100%Removed bonus damage against minions/monstersR Passive now deals an additional 2% max mana damage:HecarimMana: 277 + 60 >>> 280 +40Mana Regen: 66+ 6>>>7 +8Q Cost: 30 >>> 28-20W Cost: 50-90 >>>50-70W Omnivamp: 25 + 2% per 100 bonus AD >>> 20%, no scalingQuinn Health Growth: 99 >>>107Q Damage: 20-120 >>> 20-100E Damage: 40-160 >>> 40-140VIPassive Shield: 10% max HP >>>12% max HPPassive cooldown refund: 3 >>> 4 secondsE Cooldown: 14-8 >>> 12-8R Damage: 150-500 + 11 bonus AD >> 150-400 + 0.9 bonus ADXin ZhaoPassive Heal: 6-74 + 10% total AD >>> 3/3.5/4% max HP (Level 1/6/11)(Base heal is always higher. 1 HP per Long Sword >>> 5 HP per Ruby Crystal)4) System BuffsImmortal ShieldbowLifeline: 215-500 >>> 290-500GoredrinkerBuild path: Caulfield's Warhammer >>> Phage — Health: 300 >>> 400StridebreakerHealth: 300 >>> 3755) System NerfsBloodihirster Health Threshold: 50% >>> 70%Evenshroud Damage Amp: 10% >>> 7%Future's Market Debt Limit: 145 + 5/min >>> 100 + 8/minStatikk ShivPVP Damage: 100-180 + 30% AP >>> 100-180 + 15% AP6) System AdjustmentsCatchup XP Rounding Jungle catchup XP level difference: Always rounds up >>> Rounds normallyDragon Now displays a patience bar; Al updated to be more consistent with other jungle monstersDuskblade No longer invulnerable to damage while untargetableSpear of ShoujinBF Sword >>> PickaxeHealth: 350 >>>500Attack Damage: 65 >>> 60Dragonforce: 8 + 8% bonus AD >>> 16 + 4% Bonus AD (Buffed until 200 bonus AD)League of Legends patch 13.17 is set to go live next week and will drop on August 30, 2023.
