Overview
Patch 9.12

Hello, welcome to Patch 9.12! I'm particularly excited about this patch because my friend will finally stop going on and on about the reworked Mordekaiser. Oh, have you not heard? Mordekaiser is back, baby.

In this patch we also have Ryze's sixth (or is it seventh?) "rework," more follow-up to everyone's favorite overpowered cat, and overall nerfs to Sylas. We're also making use of the Balance Framework we published and referencing it in our explanations for some champion changes, so make sure to check that out if you haven't! (Link to it in its respective section below).

Finally, we have another round of ARAM balance changes for the Howling Abyss enthusiasts as well as some beautiful VFX updates to Lulu, Amumu, Tryndamere, and Ziggs.

Read on for the full deets!

Mid-Patch Updates[]

13/6/2019 Mordekaiser Balance Changes and Bugfixes[]

MordekaiserSquare Mordekaiser   

We're trimming a lot of Mordekaiser's general strength and pulling back on the power his passive gives him in most matchups.

BASE ATTACK DAMAGE : [65] 61
BASE ARMOR : [39] 37
MAGIC RESIST GROWTH : [1.5] 1.25
ARMOR GROWTH : [4] 3
DARKNESS RISE DAMAGE : [10-35.5 (1-6.1% of target's maximum health)]
8-25 (1-5% of target's maximum health)
DARKNESS RISE MOVEMENT SPEED : [5-10% at levels 1-6]
3/6/9% at levels 1/6/11
REALM OF DEATH BUGFIX : The Death Realm VFX no longer stays on-screen when the target dies and until someone else is brought back into the Death Realm

ThreshSquare Thresh   

BUGFIX : After Thresh's Dark Passage expires, the enemy team's Trundle no longer heals for an excessive amount of health

13/6/2019 Yuumi Bugfixes[]

YuumiSquare Yuumi   

YOU AND ME! BUGFIX : If Yuumi gets hard CC'd during her dash, her basic abilities will no longer disable for a short amount of time

Dark Cosmic Jhin, Dark Star Shaco, and Dark Star Karma will be available on June 13, 2019.

Balance Framework[]

Last week, we introduced the Champion Balance Framework, a source for all players to hold the “balance” team accountable for how we approach buffing/nerfing champions on a patch-to-patch basis. Moving forward, we'll be referencing principles, thresholds, and specific audiences from the post when explaining the changes in the Patch Notes. For more details and information, you can find the full Champion Balance Framework post here.

Champions[]

MordekaiserSquare Mordekaiser   
The Iron Revenant

The unstoppable juggernaut is back from the afterworld and ready to conquer the land of the living in patch 9.12!

High-res versions of Mordekaiser's updated splash arts are available on League Displays!
RyzeSquare Ryze  
Q spell ranks decreased, shield removed, damage bonus now dependent on R. W now slows; Spell Flux bonus converts slow to root.

When Ryze is played optimally, he covers his weaknesses incredibly well. At the same time, he benefits highly from a coordinated team. Pro play relishes champions with these characteristics, which is why he's been such a strong pick in the space. We're chipping away at these strengths to quell his presence there, but at the same time, helping out those who are looking to pick him up and aren't as precise in their combos.


With the removal of his shield, he'll have fewer means of survivability against bad match-ups, and by changing his CC to a slow, his gank targets should have better chances of escaping a 2v1 (especially a Flash > Rune Prison combo). As part of the general adjustments we're making to make him more welcoming to less experienced players, we're also opening up the bouncing game a bit more by making Spell Flux always bounce off its primary target, and placing some scaling into a passive on Realm Warp. Then there’s a bunch of tuning to account for those changes. It’s not what we would typically call a rework, but since it’s Ryze, we’ll count it. Looking forward to v7 (v8?)!

Base Stats
MANA : [400] 300
MANA REGEN : [6] 8

Overload Q - Overload

MAXIMUM CAST RANGE : [1750/3000] 3000
COOLDOWN : [180] 210/180/150 seconds

SylasSquare Sylas  
Passive now stores up to 2 charges; base damage increased; AoE damage less effective against minions. Q detonation damage and AoE range decreased on minions. W heal increased. E shield adjusted and cooldown increased later.

Sylas continues to be a high-tier competitive champion despite struggling in the hands of most players. We're taking some swings at aspects of his kit that are more powerful in pro, such as the on-demand nature of his shield and his AoE wave clear.

Petricite Burst Passive - Petricite Burst
CHARGES Now stores up to 2 charges which will be consumed on subsequent basic attacks
BASE DAMAGE : [5-47.5]
9-60
MINIONS ARE FRIENDS Deals 70% less damage to minions

18/17/16/15/14
ABDUCT SHIELD Grants a 80/115/150/185/220 (+1.0 AP)shield on enemy champion or monster hit for 2 seconds

YuumiSquare Yuumi  
Base health increased. Passive mana refund decreased early; shield decreased. W shared adaptive force adjusted; dash now interruptible by all CC.

Good Yuumis are very frustrating to play against and have virtually no windows of vulnerability—and more players are starting to get good at Yuumi. With this in mind, we're pulling some of the mid-patch buffs we gave her at release and nerfing her defenses to open up some weaknesses. Also, bugfixes and usability improvements!

Base Stats
HEALTH : [432.36] 480

Bop 'n' Block Passive - Bop 'n' Block

MANA REFUND : [40-160]
30-160
SHIELD : [80-360 (+0.40 AP)]
80-300 (+0.30 AP)

Prowling Projectile Q - Prowling Projectile

BUGFIX : Fixed a bug where the missile would not spawn towards the cursor as intended

You and Me! W - You and Me!

KILL THE CAT : Enemies now gain an assist on Yuumi when damaging the ally Yuumi is attached to
SHARED ADAPTIVE FORCE [5/9/13/17/21% of her attached ally's adaptive force] 5/7/9/11/13 flat adaptive force (+4/7/10/13/16% of her attached ally's adaptive force)
AND I OOP : Yuumi's dash can be interrupted by [knock-ups and knockbacks]
any immobilizing CC
BUGFIX : Fixed a bug where Yuumi would detach unintentionally when trying to attach to another champion outside of her range

Quality of Life Changes

SPECTATOR MODE : Range rings for Yuumi's Q, W, and R no longer show on Spectator Mode
SNEAKY SNEAKS : Yuumi now gains the same stealth screen overlay and fade on her model when attached to a champion in stealth
SADAKO'S JEWELRY : The ally that Yuumi's attached to now has a ring around them that only Yuumi can see

Simple Champion Changes[]

AatroxSquare Aatrox  
Passive cooldown now scales based on level. R healing bonus now only applies to self-healing.

We're following-up with the changes we made to Aatrox in 9.9 since right now he heals way too often in lane (via his passive) and heals way too much late-game (from book cats and star goats).

Deathbringer Stance Passive - Deathbringer Stance
COOLDOWN : [15] 24-12 (level 1-18) seconds

World Ender R - World Ender

HEALING BONUS : [All incoming healing] Self-healing only

AsheSquare Ashe  
W cooldown decreased.

Ashe could use more power, so we're specifically buffing the ability that she uses most to keep enemies at bay.

Volley W - Volley
COOLDOWN : [15/12.5/10/7.5/5]
14/11.5/9/6.5/4

CaitlynSquare Caitlyn  
Base attack damage increased.

This is definitely a small buff, but we're being extra cautious with her since she has a tendency to take over metas.

Base Stats
ATTACK DAMAGE : [58] 60

IreliaSquare Irelia  
E cooldown increased; range decreased

Due to her dominance in pro play, we're making Irelia pay a higher cost when she fails to stun her enemies with Flawless Duet. The decreased range should also make it riskier for her to go all-in.

Flawless Duet E - Flawless Duet
COOLDOWN : [14/13/12/11/10]
18/16.5/15/13.5/12
RANGE : [850] 775

KarmaSquare Karma  
Q slow increased. E cost decreased; movement speed duration increased to match shield duration.

We're giving Karma more tools to help her survive, especially when she's caught out by herself.

Inner Flame Q - Inner Flame
SLOW : [25%] 35%

Inspire E - Inspire

COST : [60/65/70/75/80]
50/55/60/65/70
MOVEMENT SPEED DURATION : [1.5] 2.5 seconds (now matches shield duration)

LuluSquare Lulu  
VFX on all abilities updated. E shield increased; cost decreased later.

Buffs to help out support Lulu and bring her back into consideration. We've also updated her VFX to make her magic feel more unique and improve her gameplay clarity.

VFX Updates
BASIC ATTACK : New purple-ier missiles and hit effects
ALL SKINS : Cleaned up to match the new effects on the base skin
DRAGON TRAINER LULU : Pix now shoots out small pink fireballs

Help, Pix! E - Help, Pix!

SHIELD : [70/105/140/175/210]
80/115/150/185/220
COST : [60/70/80/90/100]
60/65/70/75/80
VFX : Cleaned up shield (on allies) and improved Pix's teleport and hit effects (on enemies)

Pix, Faerie Companion Passive - Pix, Faerie Companion

VFX : Cleaned up Pix's bolts

VFX : New purple-ier missiles and hit effects

Whimsy W - Whimsy

VFX : Cleaned up buff effect (for allies) and missiles/hit effects (on enemies)

VFX : Fairy dust, an entirely new and pretty AoE, and cleaned up enemy hit and slow effects

Master YiSquare Master Yi   

Fixed a bug on Master Yi's passive.

Double Strike Passive - Double Strike
BUGFIX : Fixed a bug where Master Yi's Double Strike stacks were lasting 3 seconds instead of 4

NautilusSquare Nautilus  
Q base damage decreased early.

We're reducing Nautilus' early all-in damage since he's currently too strong in higher areas of play.

Dredge Line Q - Dredge Line
BASE DAMAGE : [100/145/190/235/280]
80/130/180/230/280

ZacSquare Zac  
W base damage increased. R knockback distance and chunk spawn adjusted.

Zac is significantly weaker after his revert in 9.11. We're following up on his ultimate to be closer to the original version and helping out his early clear speed which has been slow.

Unstable Matter W - Unstable Matter
BASE DAMAGE : [15/30/45/60/75]
25/40/55/70/85

Let's Bounce! R - Let's Bounce!

KNOCKBACK DISTANCE : [400 units away from Zac]
250 units from where target is hit
CELL DIVISION CHUNK SPAWN : [Each enemy champion spawns a chunk the first time they're hit by a bounce (subsequent bounces on the same enemy won't spawn additional chunks)]
Each bounce that hits one or more enemy champions spawns a chunk (hitting the same enemy still spawns a chunk)

Items[]

ItemSquareCorrupting PotionCorrupting Potion  
Bonus magic damage flattened.

Corrupting Potion is a dominant choice in pro and higher skill play. We're taking it down a notch so other options have an opportunity to shine.

BONUS MAGIC DAMAGE Over Time : [15-30 (level 1-18)] 15 at all levels

ARAM Balance Changes[]

We've made an adjustment to the calculations that go into designating your Champion Mastery Grade at the end of an ARAM game to better represent the nuances of the game mode! Additionally, more nerfs and buffs!
