Meow! Continue reading for more information!

Check out the Patch 9.10 notes (be sure to check regional editions for slight variations!):
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!

Patch Highlights




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 DAMAGE70/90/110/130/150 (+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 DAMAGE40/90/140/190/240 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 DEBUFFSRiposte 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 DAMAGE85/115/145/175/205  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 TIMENo longer takes 0.1 seconds to cast
NEWBETA STRIKEIf 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 TIMENo longer takes 0.05 seconds to cast

E - Wuju Style

REMOVEDNo longer grants 10% attack damage while not on cooldown

R - Highlander

MOVEMENT SPEED25/35/45% 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

COOLDOWN13 seconds at all ranks  12/11.5/11/10.5/10 seconds

E - Valor

COOLDOWN10/9/8/7/6 seconds  14/13/12/11/10 seconds


R casts adjusted.
We're modernizing Shaco's ultimate.

R - Hallucinate

APPEARRandom 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 APPEARRandom 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 SPEED14/18/22/26/30%  15/20/25/30/35%
MOVEMENT SPEED DECAYRapidly  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

COOLDOWN13/12/11/10/9 seconds  12/11/10/9/8 seconds
RATIO1.0 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 REDUCTION50% 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

COOLDOWN9/8/7/6/5 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

FERTILIZERDamage 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 FREQUENCYEvery 2 attacks  Every 3 attacks
ARMOR PENETRATION6% (+0.5% per level, 15% max)  15%
MAGIC PENETRATION6% (+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 DOGSPassive burn effect now applies on attacks from pets
ITEM FAMILYAlso 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 COST375 gold  250 gold
TOTAL COST2625 gold  2500 gold



True damage and healing decreased.
We hear you. It's too strong, so we're nerfing it.
GR8At 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 DAMAGEChampion 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 FREQUENCYMinion 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 SPEEDMinions speed up after the first 15 minutes of the game  18 minutes of the game
DEATH TIMER AT LEVEL 1845 seconds  40 seconds

Upcoming Skins & Chromas

New Champion: Yuumi

Our newest champion, Yuumi, the Magical Cat, will be available in patch 9.10!

Yuumi, the Magical Cat

"A magical cat from Bandle City, Yuumi was once the familiar of a yordle enchantress, Norra. When her master mysteriously disappeared, Yuumi became the Keeper of Norra's sentient Book of Thresholds, traveling through portals in its pages to search for her. Yearning for affection, Yuumi seeks friendly companions to partner with on her journey, protecting them with luminous shields and fierce resolve. While Book strives to keep her on task, Yuumi is often drawn to worldly comforts, such as naps and fish. In the end, however, she always returns to her quest to find her friend."

 Yuumi's release skin is Battle Principal Yuumi!

Battle Principal Yuumi

1350 RP
"Following the disappearance of two principals, Yuumi has stepped in as the acting head of Durandal Academy until either individual can be found and re-instated. As a powerful channeler of magic, she uses the academic registry book as a focus object to generate apocalyptic levels of energy\u2026 often while perched on a terrified student's head."

Champion Skins

Six new skins will be available in Patch 9.10, all from the new Battle Academia skin line:

Battle Academia Ezreal

1820 RP (Legendary)
"A young orphan initially thought devoid of any superhuman abilities, Ezreal had resigned himself to a normal life once he graduated middle school. But an encounter with a deadly threat awakened his slumbering potential, and now he finds himself a 1st year at the prestigious Durandal God-Weapon Academy, where he's joined the ragtag Battle Club."

Battle Academia Jayce

1350 RP
"A prestigious 2nd year whose face is known throughout the wider city of Durandal, Jayce is the class president, head of the world-renowned Luminary Club, and prodigious inventor of miraculous Jayce-branded technologies. He hopes his inventions will prevent the kind of tragedy that struck him in his youth, though he refuses to speak about what that was."

Battle Academia Katarina

1350 RP
"Katarina is a rough-edged loner who stays far away from the politics of Durandal Academy. A 2nd year student with a chip on her shoulder, she is also a top member of the Assassin Club-- the only club on campus allowed to kill opponents in school-sanctioned duels. Few other students ever dare approach her."

Battle Academia Lux

1350 RP
"A 1st year at the Durandal God-Weapon Academy, Lux maintains an upbeat attitude no matter the odds. Despite her freshman position in the Sorcery Club, Lux wields a tremendous amount of magical power that even the Academy's senior staff can't quite explain."

Battle Academia Lux Prestige Edition

[No details on availability just yet!]

Battle Professor Graves

1350 RP
"Graves is a salty ex-soldier who served in the Durandal military before he reluctantly became a professor. Following his discovery of something deep behind enemy lines, he received an offer to teach at the Academy from the God-Weapon itself. His hallmark cigar-munching, dispassionate teaching etiquette is a small price to pay for his decades of experience."

      • Atlantean Fizz: "When I was very young, my grandfather told me stories of Atlantis-- of their high temples and great undersea army, and their great General Fizz. Grandfather remembered it as it was, you see, and not the silent mausoleum it has become."
      • Bioforge Darius: "To save his own life after being exposed to a cloud of radioactive space gas, investment banker Donald D. Darius was forced to build a suit containing the strange mixture. But the chemicals from beyond the stars warped his weakened mind, twisting him into the brutal villain known as Bioforge!"
      • Phoenix Quinn: "The daring duo Quinn and the phoenix Valor are always near when crime is afoot! Combining their legendary powers, they clean up the streets of New Valoran with a well-placed arrows and the burning flames of justice!"
      • Atlantean Syndra: "The Atlanteans were skilled in magic, we know that much is true. But the extent of their power is truly unfathomable-- to this day we cannot know if they persist in some forgotten corner of the world, reanimated by whatever dark thing has taken their once-proud city."
      • Barbarian Sion: Avoiding every social cue his roleplaying group throws his way, Sion has repeatedly rolled barbarians only to die immediately after rejoining the table. At this point he's spent more time working on character sheets than actually playing Rift Quest, and it shows: his newest barbarian's backstory reads, "Is a barbarian."
      • Super Teemo: "Evildoers beware! The archvillain-turned-superhero Teemo knows how you think-- and he's ready to strike back in the name of peace and justice! With a single deafening blast, Teemo's super sigil bursts open to envelop foes in a specially formulated toxin, leaving them ready for capture and incarceration! Thanks, Teemo!"
      • Feral Warwick: "Another of Singed's vile henchmen, Warwick is never far from his villainous master. Given wolf powers after being bitten by a radioactive wolf, Warwick has been further augmented by Singed's evil research! Will our brave heroes ever be able to stop him?!"
      • Glacial Olaf: "The villagers thought it was an avalanche. Then they saw the axe."
      • Queen Ashe: "A radiant queen once venerated as a figure reborn from legend, Ashe rules her people as the visionary leader of two great Freljordian houses. Yet two equally driven rivals oppose her queendom, as a rising darkness threatens to consume them all."
      • King Tryndamere: "A proud king who was once known only as a brutal highland swordsman, Tryndamere rules his people as the martial protector of two great Freljordian houses. Yet every day he resists the pull of an intangible evil at his back, as he has not forgotten a certain blood debt that he vowed to see repaid."
      • Chemtech Tryndamere: "A monstrous experiment created by the villainous Singed, Tryndamere was irrevocably changed when he fell into a vat of volatile chemicals. Wherever Singed goes, Tryndamere follows-- yet another dastardly villain battling against New Valoran's bravest heroes!"
      • Sir Kled: "Sir Prince Chevalier Archduke Lord Double-Earl Kled (or Sir Kled, for short) is a half-mad knight from the aptly named Kingdom of Kled, which contains exactly two subjects: Kled, and his cowardly avian mount, Skarl. Together, the pair ravage the countryside to 'reclaim' Kled's 'land', which apparently is... all land, everywhere."
      • Augmented Singed: "A dastardly villain lurking in the dark corners of New Valoran, the mild-mannered Dr. Peter Singed was transformed by a volatile chemical of his own invention—becoming the superhuman criminal known only as… Singed! Can anyone stop this vile malefactor before it's too late?!"
      • Medieval Twitch: "An assassin-for-hire living beneath Dread Fortress Zaun, Twitch is a disgusting malefactor who has tipped every one of his killing implements in moist, toxic garbage. He excitedly awaits each contract, eager to kill, steal, and destroy as much as he can."
      • Emumu: "When your friends let you down, the best thing to do is start a rock band driven by hard emotions."
      • Little Knight Amumu: "A diminutive knight whose heart is brave and true, Sir Amumu of Shurima wants only to see peace reign the land in his lifetime. Considering that he's an undying, mummified princeling, he'll probably succeed."
      • Executioner Mundo: "Mundo is a man of few words, only appearing in public after donning his infamous executioner's cowl. Where this mad giant came from, and what he wants, no one can say… but he loves to execute prisoners, and does so as he pleases."
      • White Mage Veigar: "A master of healing magic residing within an ancient cathedral, Veigar self-identifies as a dastardly archvillain rather than the pious cleric he clearly is. His magic has cured ailments and dispelled curses from across the land, much to his chagrin."
      • Baron Von Veigar: "Ruler of the New Bandle Republic, Veigar considers himself the ultimate dark power of the wasteland—an evil so great that no man, woman, or creature would ever dare challenge his authority. Recently, he fixed up a water purifier and an electric grid for the city, too. An electric grid… OF EVIL!"
      • Superb Villain Veigar: "The villainous Veigar is at it again! Reigning from the top floor of the Veigar Company skyscraper, the criminal mastermind hatches the vilest plans New Valoran has ever seen! Yet even when his schemes are foiled, he always escapes punishment, biding his time until his next chance to strike!"
      • Glacial Malphite: "That's no glacier…"
      • Frozen Terror Nocturne: "Somewhere, hidden beneath the enormous ice caps, lurks a demon fueled by the terror of those foolish enough to enter his domain."
      • Gothic Orianna: "Her father gave her the light of life—and yet, Orianna always preferred the dark."
      • Apocalyptic Brand: "Before the devastation of Runeterra, Kegan Rodhe was a search-and-rescue specialist deployed to active wildfire zones. When the bombs went off, the world vanished in the blink of an eye—and Rodhe along with it. All that was left was the empty wasteland… and a monstrous creature of living flame, calling itself Brand."
      • Cryocore Brand: "An elite soldier of a military wetworks unit, Kegan Rodhe was left behind enemy lines deep in the frozen arctic! But instead of dying, Rodhe found himself captured by a cabal of evil scientists, whose brutal experiments transformed him into the diabolical villain Cryocore!"
      • Blast Zone Heimerdinger: "An eccentric scientist living in the New Bandle Republic, Heimerdinger has not yet told anyone he may have developed “a large pre-war bomb or two” for “one or more rogue governments”. He would prefer tinkering in a city that is not actively trying to kill him."
      • Blacksmith Poppy: "A famously gruff blacksmith working under the tutelage of Sir Ornn of the Freljord, Poppy wields a hammer imbued with a powerful magic that she believes is destined for the weapon for an unknown hero. Little does she know the hammer is the weapon, and the hero… is herself."
      • Count Vladimir: "Once upon a time, in the heart of a dark and gloomy castle, there lived an eternally youthful count who the people greatly feared. Every night, a terrible red mist would seep into the villages, and some poor soul would vanish without a trace—another life lost to Vladimir's growing appetites."
      • Kennen M. D.: "Why run with scissors when you can throw scalpels?"
      • Super Kennen: "Coming to a store near you: the new Super Kennen action figure! At 6″ tall, the new Super Kennen is fully articulated, with dazzling lightning bolt action! Add this fitting tribute to New Valoran's bravest hero to your collection today!"
      • Frozen Shen: "Enduring the bitter cold, Shen roams the ice caps with his twin blades, hunting the terrifying demon hidden deep underneath."
      • Surgeon Shen: "Rest assured, anesthesia won't be part of the operation."
      • Sorceress Lux: "An aspiring mage from the Demacian Dukedom, Lux has traveled across the land in her quest to lighten the lives of the peasantry with magic. Though her efforts are often met with suspicion at first, tales of her 'miracles' are beginning to reach the ruling class of the Dukedom itself…"
