Chronology
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[edit]

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

Mordekaiser Mordekaiser

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

Patch Highlights[edit]

Balance Framework[edit]

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.

Ryze Ryze[edit]

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?)!

Sylas Sylas[edit]

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.
Riot (Patch 9.12)
  • Passive - Petricite Burst
    • NewCHARGES : Now stores up to 2 charges which will be consumed on subsequent basic attacks
    • BASE DAMAGE : 5-47.5 (levels 1-18) ⇒ 9-60 (levels 1-18)
    • NewMINIONS ARE FRIENDS : Deals 70% less damage to minions
  • Q - Chain Lash
    • DETONATION DAMAGE : 45/70/95/120/145 (+0.60 ability power) ⇒ 40/60/80/100/120 (+0.40 ability power)

    • COOLDOWN : 18/16/14/12/10 seconds ⇒ 18/17/16/15/14 seconds
    • NewABDUCT SHIELD : Grants a 80/115/150/185/220 (+1.0 ability power) shield on enemy champion or monster hit for 2 seconds

Yuumi Yuumi[edit]

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!
Riot (Patch 9.12)
  • Base Stats
    • HEALTH : 432.36 ⇒ 480
  • Passive - Bop N' Block
    • MANA REFUND : 40-160 (level 1-18) ⇒ 30-160 (level 1-18)
    • SHIELD : 80-360 (+0.40 ability power) ⇒ 80-300 (+0.30 ability power)
  • Q - Prowling Projectile
    • BUGFIX : Fixed a bug where the missile would not spawn towards the cursor as intended
  • 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 ⇒ Yuumi's dash can be interrupted by 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[edit]

Aatrox Aatrox[edit]

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).
Riot (Patch 9.12)
  • Passive - Deathbringer Stance
    • COOLDOWN : 15 seconds ⇒ 24-12 (level 1-18) seconds
  • R - World Ender
    • HEALING BONUS All : incoming healing ⇒ Self-healing only

Ashe Ashe[edit]

W cooldown decreased.

Ashe could use more power, so we're specifically buffing the ability that she uses most to keep enemies at bay.
Riot (Patch 9.12)
  • W - Volley
    • COOLDOWN : 15/12.5/10/7.5/5 seconds ⇒ 14/11.5/9/6.5/4 seconds

Caitlyn Caitlyn[edit]

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.
Riot (Patch 9.12)
  • Base Stats
    • ATTACK DAMAGE : 58 ⇒ 60

Irelia Irelia[edit]

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.
Riot (Patch 9.12)
  • E - Flawless Duet
    • COOLDOWN : 14/13/12/11/10 seconds ⇒ 18/16.5/15/13.5/12 seconds
    • RANGE : 850 ⇒ 775

Karma Karma[edit]

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.
Riot (Patch 9.12)
  • Q - Inner Flame
    • SLOW : 25% ⇒ 35%
  • E - Inspire
    • COST : 60/65/70/75/80 mana ⇒ 50/55/60/65/70 mana
    • MOVEMENT SPEED DURATION : 1.5 seconds ⇒ 2.5 seconds (now matches shield duration)

Lulu Lulu[edit]

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.
Riot (Patch 9.12)
  • 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
  • E - Help, Pix!
    • SHIELD : 70/105/140/175/210 ⇒ 80/115/150/185/220
    • COST : 60/70/80/90/100 mana ⇒ 60/65/70/75/80 mana
    • VFX : Cleaned up shield (on allies) and improved Pix's teleport and hit effects (on enemies)
  • Passive - Pix, Faerie Companion
    • VFX : Cleaned up Pix's bolts
  • Q - Glitterlance
    • VFX : New purple-ier missiles and hit effects
  • W - Whimsy
    • VFX : Cleaned up buff effect (for allies) and missiles/hit effects (on enemies)
  • R - Wild Growth
    • VFX : Fairy dust, an entirely new and pretty AoE, and cleaned up enemy hit and slow effects

Master Yi Master Yi[edit]

Fixed a bug on Master Yi's passive.
Riot (Patch 9.12)
  • Passive - Double Strike
    • {{Att|att=BUGFIX Fixed a bug where Master Yi's Double Strike stacks were lasting 3 seconds instead of 4

Nautilus Nautilus[edit]

Q base damage decreased early.

We're reducing Nautilus' early all-in damage since he's currently too strong in higher areas of play.
Riot (Patch 9.12)
  • Q - Dredge Line
    • BASE DAMAGE : 100/145/190/235/280 ⇒ 80/130/180/230/280

Zac Zac[edit]

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.
Riot (Patch 9.12)
  • W - Unstable Matter
    • BASE DAMAGE : 15/30/45/60/75 ⇒ 25/40/55/70/85
  • 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[edit]

Corrupting Potion[edit]

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.
Riot (Patch 9.12)
  • BONUS MAGIC DAMAGE : 15-30 (level 1-18) over 3 seconds ⇒ 15 at all levels over 3 seconds

ARAM Balance Changes[edit]

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!
Riot (Patch 9.12)
  • END OF GAME MASTERY GRADE : Modified calculations to be more accurate for ARAM
