Patch 10.12 notes

Updated runes, elemental terrain, and...ghost!

Happy June! Y'all ready for a summer of fun (safely indoors on League?)

This patch, we dipped our toe in the usual pool, adjusting some champions that have been standing out, some of whom have been in a rough spot (Akali, Brand, Viktor, Xayah). We're also carefully dialing down a few pro outliers, like Trundle and Varus, to a fairer middle ground in the scope of the game. Finally, we're pushing a few changes and smoothing out a couple bugs to our epic savage of a bear.

But more noticeably, we've done a pass on some of our more underutilized and niche runes to broaden their use for more champions. Some felt just too unintuitive to really understand the benefits they were giving and some just felt too difficult to actively trigger for the maximum value. Hopefully, these changes will help players widen their horizons when it comes to picking runes that best suits their playstyle. We also went and did a similar check for Summoner Spells and found that Ghost was in the same boat as the affected runes. Now, those looking to be faster than a certain blue hedgehog might feel more compelled to ghost their other Summoner Spell options and check this one out for size.

Mid-Patch Updates

6/15/2020 Kayn Bugfix


W - BLADE'S REACH BUGFIX Kayn is no longer able to globally cast W - Blade's Reach to all enemies on the map

Patch Highlights

High Noon Senna, High Noon Irelia, and Hextech Nocturne will be available on June 18, 2020



Q damage increased.

Akali’s full of cold steel and competitive potential, but we aren’t really seeing her in pro play yet. Since she’s normally limited by pro, we’re giving her some baseline effectiveness by boosting her bread-and-butter damage ability.

Q - Five Point Strike

DAMAGE 25/50/75/100/125 (+0.65 total attack damage) (+0.6 ability power) 30/55/80/105/130 (+0.65 total attack damage) (+0.65 ability power)


Increased mana restore on Ablazed enemy takedowns.

Bringing up Brand’s mana restore in the hopes that it’ll punch up his mid lane status without pushing his power as a support over the line. We’re pushing this mid-favored lever way harder than ever before to see if it’s effective in making him viable there.

Passive - Blaze

ABLAZED KILL MANA RESTORE 6-18 (levels 1-18) 20-40 (levels 1-18)


Base health and armor decreased; magic resist increased.

This serpent has been embracing both top and bot with open arms, and we’re primarily aiming for these changes to scale back her prowess in those lanes. With that being said, we’re softening the nerf to mid lane Cass by subtly bumping up her magic resist defenses.

Base Stats

HEALTH 575 560
ARMOR 20 18


W minion damage reduction increased.

Fiddlesticks reaped more benefits than we’d intended with our last set of buffs, so we’re trimming down his power around minion waves while taking care not to scare him off top lane.

W - Bountiful Harvest



Bugfix on attack windup time. Passive mist wraith drop chance increased.

ADC Senna’s been in a weak spot since her last set of changes in 10.6, so we’re giving her more chances to redeem more benefits from farming. We've also fixed a bug that caused her to have longer auto windups while critting, which should significantly improve her crit itemization.


BUGFIX Fixed a bug where Senna's crit attacks weren't reducing her attack's windup time correctly

Passive - Absolution

MIST WRAITH DROP CHANCE 1.67% on minions Senna kills 8.33% on minions Senna kills


Base health, mana, and mana regen rounded. W bonus movement speed decreased.

Though we took some power out of his Subjugation, Trundle is still the top troll in competitive play. We’re aiming at reducing his safe escapes from sticky situations by toning down his early mobility. Also rounding some base stats out because those decimals are as ugly as he is.

Base Stats

HEALTH 616.28 616
MANA 281.6 281
MANA REGEN 7.508 7.5

W - Frozen Domain

BONUS MOVEMENT SPEED 30/35/40/45/50% 20/28/36/44/52%


Base attack damage growth decreased. Q damage ratio decreased.

Varus' Lethality build is overtaking his other options, especially in pro play— and he’s just generally blighting his competition overall. This build makes him an early game powerhouse and we don’t want to take that away from him, so we’re tuning down his scaling so that he pays a fairer cost later in the game.

Base Stats


Q - Piercing Arrow

DAMAGE RATIO 1.1 attack damage (1.65 maximum) 1.0 attack damage (1.5 maximum)


Q discharge damage ratio increased; shield ratio increased.

Empowering Viktor’s mid-range dueling so that he doesn’t have to solely rely on his E to be effective.

Q - Siphon Power

DISCHARGE DAMAGE RATIO 0.55 ability power 0.6 ability power
SHIELD RATIO 0.15 ability power (0.24 ability power when empowered), 0.2 ability power (0.32 ability power when empowered)


Gameplay clarity improvements. Base mana growth and health growth increased. Q bugfixes and QoL changes. W bugfixes. R turrent disable duration, epicenter damage radius increased, and base damage increased; bugfixes.

Since release, Voli has been underperforming in his top lane, especially in higher levels of play and even with the mid-patch updates from earlier this week. Which is fine in theory since his top lane is secondary to his primary role (jungle), but the difference is just a little too wide at the moment.

So these additional changes focus on improving the fluidity of his ability casts and gameplay satisfaction, while also giving him some general baseline strength. Now, hitting abilities and outplaying your opponents should result in some tangible success (takedowns, successfully escaping, etc.)


IMPACT CRATERS Volibear's E - Sky Splitter and R - Stormbringer impact craters now disperse faster
VISUAL GAMEPLAY CLARITY Improved the visual clarity of several of Volibear’s spells, including W - Frenzied Maul, E - Sky Splitter, and R - Stormbringer.
BEARS LOVE TO SING Fixed a bug that caused Volibear to hum way, way too often
ETERNALS Volibear's Eternals are now live

Base Stats


Q - Thundering Smash

BEAR WITH IT Thundering Smash's empowered attack can no longer be interrupted by crowd control once it's been initiated
ATTACK SPEED SCALING Thundering Smash's empowered attack now scales its timing with attack speed
RESET BUGFIX Volibear's Thundering Smash reset will no longer fail if quickly recasts after being interrupted

W - Frenzied Maul

ANIMATION CANCEL BUGFIX Volibear will now automatically attack his target after canceling his Frenzied Maul and E - Sky Splitter animations
ATTACK BUGFIX Volibear will now continue to attack his target even after casting Frenzied Maul on them
MARK VFX Made larger and better anchored to the target's health bar

R - Stormbringer

TURRET DISABLE DURATION 2/4/6 seconds 3/4/5 seconds
BASE DAMAGE 250/475/700 300/500/700
ATTACK BUGFIX Fixed a bug that caused Volibear to automatically basic attack a target after landing via R - Stormbringer
MODEL SIZE Reduced slightly
TURRET DISABLE VFX Turrets disabled with R - Stormbringer are also now much darker to denote their status.


R base damage increased.

After dominating pro play for most of last season, Xayah’s been plucked from the top tiers. Buffing her R damage to reward more aggressive plays. Go on, ruffle some feathers!

R - Featherstorm

BASE DAMAGE 100/150/200 125/250/375


Base health decreased. Passive shield increased. W cooldown increased.

Yasuo has been outshining in bot while remaining rather lackluster in solo lanes, so we’re bringing up the cooldown on a spell that is the most effective there while giving him a little padding on his shield, since it’s easier for bot lane enemies to poke it down. We’re hoping these careful adjustments will reduce his power bot while impacting him less when he’s solo.

Base Stats

HEALTH 523 490

P - Way of the Wanderer

FLOW SHIELD ACTIVATION 100-510 (levels 1-18) 115-525 (levels 1-18)

W - Windwall

COOLDOWN 26/24/22/20/18 seconds 30/27/24/21/18 seconds


updatedApproach Velocity

Approach Velocity and Unflinching have very low pickrates and unintuitive functionality. The goal is to broaden them so more champions can use them, while also making them simpler so each rune is more understandable.
PASSIVE Gain 15% bonus movement speed toward movement-impaired allies or enemies you've impaired Gain 7.5% bonus movement speed when moving toward a movement-impaired enemy champion. Increased to 15% if you were the one who impaired their movement (There is no longer a maximum range of 1000 for champions that you have CCd)


Guardian is a powerful keystone that’s been largely unpicked and ignored, despite outperforming other keystones like Aery and Aftershock on individual champions. We’re zhuzzing it up by giving players more agency over when it triggers and sharpening its intended defensive output by replacing the movement speed buff with extra strength in the shield. Altogether, we’re aiming for this keystone to still have a similar power level despite these changes, but finessed in a way that is less frustrating and more reliable to play around with. Maybe it’s time to let your guard down with this one!
TRIGGER CONDITION Any damage 90-250 postmitigation damage in the last 2.5 seconds or lethal damage
SHIELD AMOUNT 70-150 80-200
removedMOVEMENT SPEED 20% No longer gives movement speed


While delivering on an excellent fantasy, Predator often loses sights on its prey by having a difficult cast paradigm and unintuitive optimizations. We’re attempting to broaden it from its niche role on a few junglers to making it more of a standard initiation option.
COOLDOWN 150-100 seconds 100-70 seconds
DAMAGE 60-180 (+0.4 bonus attack damage) (+0.25 ability power) 30-90 (+0.2 bonus attack damage) (+0.1 ability power)
I’M GOIN, I’M GOIN Active is no longer disabled for the first 150 seconds of the game.
newRUN, RUN AS FAST AS YOU CAN Upon completion, Predator now grants 45% bonus movement speed while moving towards enemy champions at a range of 3000, including enemy champions out of vision
removedCHANNEL INTERRUPTION Active is no longer interrupted if you cast an ability or enter combat (still has a 1.5 second ramp up time for damage effect and full movement speed)
newCHARLIE, THAT HURTS Predator now only deals damage and ends the hunt against enemy champions.
DURATION 15 seconds 10 seconds

Taste of Blood

QoL cooldown indicator change.
INDICATOR Taste of Blood's Icon above the player's HUD now appears while it's on cooldown


Unflinching and Approach Velocity have very low pickrates and unintuitive functionality. The goal is to broaden them so more champions can use them, while also making them simpler so each rune is more understandable.
PASSIVE Gain 10% slow resist and 10% Tenacity for each of your summoner spells on cooldown, stacking up to 20%. Gain 15% slow resist and 15% Tenacity for 10 seconds whenever you cast a summoner spell Gain 10% slow resist and 10% Tenacity. Gain up to 20% more slow resist and Tenacity based on missing health

Summoner Spells


Ghost has been a non-viable summoner for many champions for a long time now. Adding some power that emphasizes its strengths relative to other summoner spells with a sustained mobility effect for those using it aggressively.
newGHOSTING THE BUILD-UP Ghost's movement speed now activates instantly
newTAKEDOWN MS EXTENSION Ghost's increased movement speed duration now extends by 4-7 seconds (levels 1-18) when you get a takedown
MOVEMENT SPEED 28-45% (levels 1-18) 20-40% (levels 1-18)
COOLDOWN 180 seconds 210 seconds
