League of Legends – 8.15 Patch Notes

Welcome to patch 8.15. As mentioned in previous patches, after the significant changes in midseason, we’re mostly focusing on balancing outliers. As a result, this is a pretty small patch.

To start, we’re taking a look at marksmen. They’re still feeling some pain from their midseason changes (especially in mid-game when they can’t yet afford multiple items), so we’re decreasing the cost of their items to let them hit their power spike more quickly and decreasing their overall stats slightly to compensate.

Akali’s rework also hits the Rift this patch, so be sure to check out her new abilities.


Patch Highlights



Akali, the Rogue Assassin strikes in patch 8.15! Make your own path with these links:


E cost increased at early ranks. E base damage decreased.

Fiddlesticks ability to poke (particularly as a support in bot lane) is currently too high.

 E – Dark Wind

COST 50/60/70/80/90 mana  70/75/80/85/90 mana
BASE DAMAGE PER HIT 65/85/105/125/145  60/80/100/120/140


W active base damage increased. W active and on-hit damage ratios increased. R ability power ratios increased, increased less for larger sharks.

The recent changes to Fizz have left him weaker on damage than intended.

 W – Seastone Trident

ACTIVE BASE DAMAGE 40/50/60/70/80  50/70/90/110/130
ACTIVE DAMAGE RATIO 0.4 ability power  0.6 ability power
ON-HIT DAMAGE RATIO 0.3 ability power  0.4 ability power

 R – Chum the Waters

GUPPY DAMAGE RATIO 0.6 ability power  0.9 ability power
CHOMPER DAMAGE RATIO 0.9 ability power  1.1 ability power
GIGALODON DAMAGE RATIO 1.2 ability power  1.3 ability power


Attack damage increased. Health increased. Passive damage increased. Q range, base damage, and damage ratio decreased. E range and base damage decreased. R range decreased.

As a continuation of our changes to Irelia, we’re shifting more of her power out of her abilities and into her basic attacks.

Base stats

HEALTH 550  580

 Passive – Ionian Fervor

DAMAGE PER STACK1-12 (at levels 1-18)  4-17 (at levels 1-18)

 Q – Bladesurge

RANGE 625  600
BASE DAMAGE 10/30/50/70/90  5/25/45/65/85
DAMAGE RATIO 0.7 total attack damage  0.6 total attack damage

 W – Defiant Dance

DAMAGE REDUCTION 45/50/55/60/65%  50%

 E – Flawless Duet

RANGE 900  850
BASE DAMAGE 80/120/160/200/240  70/110/150/190/230
REMOVEDMONSTER REDUCTION No longer deals 50% damage to monsters

 R – Vanguard’s Edge

RANGE 1050  1000


W attack speed scaling (for Wolf) decreased. R cooldown increased.

Recent bugfixes gave Kindred far more of a bump than expected, and as a result they have emerged as a dominant jungler. Pulling back some power and aligning their ultimate cooldown with other similarly game-changing ultimates.

 W – Wolf’s Frenzy

WOLF BONUS ATTACK SPEED 50% bonus attack speed  25% bonus attack speed

 R – Lamb’s Respite

COOLDOWN 160/130/100 seconds  180/150/120 seconds

Lee Sin

Q base damage decreased. Q damage ratio increased. No longer deals damage based on target’s missing health damage. Now scales amplified damage based on target’s missing health.

Lee Sin is an aggressive, snowball-oriented champion and we want to make sure he is appropriately rewarded when he does get ahead.

 Q – Sonic Wave / Resonating Strike

BASE DAMAGE 55/85/115/145/175  50/75/100/125/150
DAMAGE RATIO 0.9 bonus attack damage  1.0 bonus attack damage
REMOVEDEXECUTE DAMAGE No longer deals 8% of target’s missing health as damage
NEWEXECUTE DAMAGE Now deals up to 100% increased damage based on target’s missing health


Base mana regen decreased. Black Shield cost increased.

In her other roles, Morgana’s ability to spam spells is gated by the harsh mana scaling on her W, but as a support (where she maxes W last), she has too much lane consistency.

Base Stats

MANA REGEN 15 mana per 5 seconds  11 mana per 5 seconds

 E – Black Shield

COST 50 mana  80 mana


W bonus attack speed increased.

Bumping up the berserker’s clear speed to give him some strength back.

 W – Vicious Strikes

BONUS ATTACK SPEED 40/50/60/70/80%  55/65/75/85/95%


Armor decreased. Passive damage decreased.

Quinn’s lane strength has started to become a bit of an issue. As a ranged champion, when she does get hard-engaged on she shouldn’t be quite so hard to kill.

Base Stats

ARMOR32  28

 Passive – Harrier

BASE DAMAGE15-100 (at levels 1-18)  10-95 (at levels 1-18)


Q base damage increased.

This should put some power into Syndra’s early game.

Q – Dark Sphere

BASE DAMAGE 50/95/140/185/230  70/110/150/190/230


W cooldown decreased at later ranks. E maximum attack damage contribution increased at early ranks.

We feel like Thresh could use a bit more power, specifically in his early game all-in potential and his late-game playmaking options.

 W – Dark Passage

COOLDOWN 22/20.5/19/17.5/16 seconds  22/19.5/17/14.5/12 seconds

 E – Flay

MAXIMUM ATTACK DAMAGE CONTRIBUTION 80/110/140/170/200% 100/125/150/175/200%


Support Items

Cost of starting support items increased.

The current cost of support items lets support players mitigate a pretty high amount of poke through potions, which makes trading feel more ineffective than we’d like.

Ancient Coin, Relic Shield & Spellthief’s Edge

COST 350 gold  400 gold
NEWTWISTED TREELINE These changes also apply on Twisted Treeline.

Nomad’s Medallion, Targon’s Brace & Frostfang

TOTAL COST 850 gold (unchanged)
COMBINE COST 500 gold  450 gold
NEWTWISTED TREELINE These changes also apply on Twisted Treeline.

Marksman Itemization

Our goal of giving marksmen a later spike was hit a little bit too hard, and it’s left marksmen feeling underwhelming in the mid-game (and thus often unable to reach their late-game power). We’re decreasing the cost of some marksman items so they spike earlier, but cutting some of their late-game power so they don’t take over the game when they get there.

Infinity Edge

Total cost decreased. Build path changed. True damage decreased. Attack damage decreased.

Cheaper items (with fewer stats to compensate) should help marksmen reach a reasonable spike earlier.

TOTAL COST 3600 gold  3400 gold
BUILD PATH BF Sword + BF Sword + 1000 gold  BF Sword + Pickaxe + 1225 gold
UPDATED TRUE CRIT TEXT“True Damage Critical Strikes” now display as a blue/white icon instead of the purple “Magic Damage Crit” icon


Cost decreased. Attack damage decreased. Attack speed decreased.

Cheaper items (with fewer stats to compensate) should help marksmen reach a reasonable spike earlier.

BUILD PATH BF Sword + Pickaxe + Dagger + Dagger + 425 gold  BF Sword + Long Sword + Long Sword + Dagger + 500 gold
TOTAL COST 3200 gold  2800 gold

Essence Reaver

Attack damage increased.

In 8.12, we made some changes to Essence Reaver that were intended to make the item more accessible, but it looks like those changes also slightly weakened the item overall. As a result, we’re adding some power back.


Zeal Items

Gold cost decreased

 Rapid Firecannon, Statikk Shiv & Runaan’s Hurricane

GOLD COST 2900 gold  2800 gold

 Phantom Dancer

GOLD COST 2800 gold  2700 gold

Mercurial Scimitar

Total and combine cost decreased. Attack damage decreased.

There should be clear tradeoffs in itemization; in the case of Mercurial Scimitar, the extra safety from its active does not hold an appropriate tradeoff in damage dealt.

TOTAL COST 3700 gold  3500 gold
COMBINE COST5 25 gold  325 gold

Jungle Items

Monster Hunter restriction now applies if the champion has the highest minion kill score, not the most gold.

The previous Monster Hunter had the effect of inhibiting the snowball of a jungle who got ahead with kills, not just a champion who was duo-farming the jungle. We’re changing the mechanic to only restrict champions who have the highest minion score, not the highest gold.

REMOVEDSHARE THE LOAD If you have the most individual total gold on your team, lane minion kills will grant 10 less gold
NEWSHARE THE LOAD If you have the highest minion score on your team, lane minion kills will grant you 10 less gold
NEWTWISTED TREELINE The Monster Hunter changes also apply on Twisted Treeline.


Perfect Timing

Time of activation pushed to later in the game.

In patch 8.4, we pushed the activation time of Stopwatch to 10 minutes because its prevalence in professional play was delaying or inhibiting early action. In 8.10 we tried a lower value (8 minutes), but we’ve begun observing the same impact on pro play, so we’re reverting those changes.

ACTIVATION TIME 8 minutes  10 minutes
