Patch 9.10 notes

By Aether, shio shoujo

Hello fur-ends! Welcome to 9.10, the one where we greet the one, the only, the purr-fectly wonderful, Yuumi!

This patch, while smaller than the last, contains changes to some of the more spicy champions across various skill brackets like Master Yi, Riven, and Vayne. We're also following up on the changes we made to Soraka last patch to continue to encourage her ally-supporting playstyle and buffing a few champions who've been faltering as of late.

In addition, we've made some adjustments to Conqueror and Guinsoo's Rageblade due to their overperformance and must-pick natures for their core users.

Meow, let's jump right in!

Mid-Patch Updates

5/20/2019 Bugfix

Patch Highlights

Back to top




Meow meow meow. Meow mew. Meow cat meow mew 9.10, mewo.
High-res versions of Yuumi's base and release skin splash art are available on League Displays!


E damage increased late; ratio increased.

Spritzing some oil on Brand to conflagrate his eternal flame. The change favors mid-lane Brand more than his support counterpart, but he'll be a bit hotter no matter where he goes.

E - Conflagration

MAGIC DAMAGE 70/90/110/130/150 (+0.35 ability power) 70/95/120/145/170 (+0.45 ability power)


W headshot damage increased.

Helping Caitlyn out in a way that doesn't affect her already strong waveclear and late game, by focusing on when she successfully maneuvers her traps for maximum damage.

W - Yordle Snap Trap

HEADSHOT BONUS DAMAGE 40/90/140/190/240 60/105/150/195/240


W now blocks Braum's and Kennen's stuns rather than preventing them from proccing.

Previously, Fiora's Riposte stopped some champions' last passive stack from being applied, which effectively delayed the following stun rather than blocking it.

W - Riposte

INTERACTIONS WITH DEBUFFS Riposte prevents Braum and Kennen from applying the last stack of their passives allows Braum and Kennen to apply the last stack of their passives, blocking the stun (and still blocking the damage from the attack)


Q damage increased late.

Overall, Graves was feeling underwhelming, so we're giving him some power in a place that can be counterable.

Q - End of the Line

DETONATION DAMAGE 85/115/145/175/205 85/120/155/190/225

Master Yi

Q cast time removed, adjusted target scanning. W cast time removed. E no longer grants AD while not on cooldown. R movement speed increased and adjusted.

We want to increase the satisfaction on key parts of Master Yi's kit while nerfing him in ways that'll help out those who don't know how to counter him. Those with more experience won't find Master Yi significantly better or worse, but he won't continue to dominate in average play.

Q - Alpha Strike

removedCAST TIME No longer takes 0.1 seconds to cast
newBETA STRIKE If Master Yi has struck fewer than the maximum amount of times he can with Alpha Strike and there are no other nearby eligible targets, he will now strike the same target for 25% of the damage before checking for nearby targets again

W - Meditate

removedCAST TIME No longer takes 0.05 seconds to cast

E - Wuju Style

removed No longer grants 10% attack damage while not on cooldown

R - Highlander

MOVEMENT SPEED 25/35/45% total movement speed 35/45/55% bonus movement speed


Q cooldown now scales. E cooldown increased.

We're looking to target a consistent point of frustration that players face when playing against Riven—her up-time defense from spamming E. While she'll now be able to cast her Q more often, playing against her will be more manageable overall and she'll have more points of vulnerability when her E is down.

Q - Broken Wings

COOLDOWN 13 seconds at all ranks 12/11.5/11/10.5/10 seconds

E - Valor

COOLDOWN 10/9/8/7/6 seconds 14/13/12/11/10 seconds


R casts adjusted.

We're modernizing Shaco's ultimate.

R - Hallucinate

APPEAR Random position 50-250 range in any direction around cast position, facing a random direction 200 range in the direction of Shaco's cursor, facing the clone
CLONE APPEAR Random position 50-250 range in any direction around cast position, facing a random direction 200 range in the opposite direction of Shaco's cursor, facing Shaco


Q movement speed increased; decays more slowly.

Following up on the 9.9 changes to Soraka, since we missed on the power level a bit back then. These changes should be significant enough that Starcall's haste should now be a relevant factor when Soraka and her allies make heat-of-the-moment choices.

Q - Starcall

BONUS MOVEMENT SPEED 14/18/22/26/30% 15/20/25/30/35%
MOVEMENT SPEED DECAY Rapidly Significantly less rapidly


E cooldown decreased. AP ratio decreased.

Tryndamere is struggling in a world with more mobile, ranged opponents in the top lane. We're helping his mobility so he can find more of a footing in those matchups.

E - Spinning Slash

COOLDOWN 13/12/11/10/9 seconds 12/11/10/9/8 seconds
RATIO 1.0 ability power 0.8 ability power


R Tumble cooldown reduction now scales.

Similar to Riven, we want to work on targeting the frustration around playing against Vayne beyond just her raw stats. Right now, Vayne ramps up a little too early and is especially frustrating because of how often she goes invisible. These changes should lessen her power spike at level 6.

R - Final Hour

TUMBLE COOLDOWN REDUCTION 50% at all ranks 30/40/50%

Xin Zhao

Q cooldown decreased.

Now that Scuttler spawns later, other champions aren't forced to fight Xin as much at his biggest power spike. But because of that, his niche as an early game powerhouse doesn't have as big of an impact, especially on the outcome of a game. We can now help him out so he can do better throughout a game without worry.

Q - Three Talon Strike

COOLDOWN 9/8/7/6/5 seconds 7/6.5/6/5.5/5 seconds


Plants no longer take additional damage from basic attacks that do not trigger on-hit effects.

Reducing the damage Zyra's plants takes, especially from those that shouldn't trigger additional effects.

Passive - Garden of Thorns

FERTILIZER Damage from basic attacks that doesn't trigger on-hit effects (ex. Corki's Hextech Munitions, Miss Fortune's Love Tap, etc.) no longer deals a separate instance of damage to Zyra's plants

Essence Reaver

Attack damage increased.

We're giving Essence Reaver's core users more motivation to consider it as their attack damage option.

Guinsoo's Rageblade

Phantom Hit frequency decreased. Armor and magic penetration increased and flattened.

Rageblade gives too much power to champions whose abilities naturally align with the frequency of Phantom Hits. We'll be keeping an eye on how much these core users are affected since we still want to keep their Phantom Hit synergy relevant—just not as unilaterally success-defining as it currently is.
PHANTOM HIT FREQUENCY Every 2 attacks Every 3 attacks
ARMOR PENETRATION 6% (+0.5% per level, 15% max) 15%
MAGIC PENETRATION 6% (+0.5% per level, 15% max) 15%

Hunter's Talisman

Champions' pets' attacks now also apply burn.

Since pets feel like a champion's ability and abilities trigger Hunter's Talisman's burn, we're making it so that pets also apply that burn.
newHOT DOGS Passive burn effect now applies on attacks from pets
ITEM FAMILY Also applies to all of Hunter's Talisman's upgrades (Stalker's Blade, Skirmisher's Sabre, and all their variants)

Runic Echoes

Combine and total costs decreased.

Letting Runic users get their jungle enchanted item sooner so they can compete with other types of junglers, as well as encouraging non-users to experiment with the item.
COMBINE COST 375 gold 250 gold
TOTAL COST 2625 gold 2500 gold

True damage and healing decreased.

We hear you. It's too strong, so we're nerfing it.
GR8 At full stacks, 10% 8% of the damage dealt against champions is converted to true damage and healing

ARAM Balance Changes

As promised, we're continuing to update and make adjustments to ARAM following our experimental changes from 9.7. In 9.10, you'll see more balance changes to champions and runes, as well as some tweaks to the scaling tower damage and minion waves.
ADDITIONAL TURRET DAMAGE Champion damage to turrets increases after the first 15 minutes, maxing at +15% at 25 minutes 18 minutes, maxing at +25% at 30 minutes
MINION WAVE FREQUENCY Minion waves spawn faster after the first 15 minutes of the game, maxing at 15 seconds between waves at 25 minutes 18 minutes of the game, maxing at 13 seconds between waves at 30 minutes
MINION MOVEMENT SPEED Minions speed up after the first 15 minutes of the game 18 minutes of the game
DEATH TIMER AT LEVEL 18 45 seconds 40 seconds
