Patch Notes v4.18
"Hi Summoners,

Welcome to patch 4.18. While we don't have a lot of balance changes this patch, 4.18 is the launch date of one of our largest champion updates to date: Sion, the Undead Juggernaut. Be sure to check out his champion reveal page here, or just try him out in-game when he launches! But please, for the sake of you and your teammates' sanity, maybe play a few normal games with him before you queue up for ranked. I get the feeling many of you won't listen, but at least I've had my say.

Also of note within 4.18 is a whole pile of bugfixes for Azir (sorry!), a GANGPLANK BUFF!?, the removal of Pando Media Booster, a Smart Ping volume slider (look at this new audio technology we can implement!), and phase 2 of our mass champion texture rebalance! You can think of this patch as more of a small maintenance update as we look forward to the World Championships in Korea and the future of competitive League of Legends. Definitely some bigger things to come in the future, so stay tuned!

P.S. Same deal this patch about there being a larger than usual downloads. We're shipping pieces of the updated Summoner's Rift as we finish them but, once again, they won't be available to play!"

"Sion, the Undead Juggernaut, will be released with the launch of 4.18. Check out his reveal for gameplay info, his insights article for a look at his development, or his teaser for a glimpse into his story.

No more bonus resistances when Akali is in her shroud, but now whenever she stealths she gets a significant movement speed boost.

"Akali's one of those champions who, when she gets ahead, completely circumvents her meaningful weaknesses by having extra resistances from Twilight Shroud. A fed Akali ultimately turns into a bruiser-assassin Akali who hops into a fight, tanks out damage in Twilight Shroud, and then continues to obliterate the squishies. Rather than removing her defensive mechanics completely, we wanted to focus Akali's skills on more ninja-y things, hence the heavier focus on sneaking and agility. This also allows us to reinforce the proper counterplay to Akali (reveal her in stealth and beat her up), give her better themed mechanics, all while reiterating her focus on opportunistic assassinations. Up front: this is meant to be an overall nerf, but we hope Akali players will be more focused on the cool plays they can make with this new mechanic. "
  • Twilight Shroud.png W - Twilight Shroud
    • NEW NOW WITH MORE NINJA Twilight Shroud now gives +20/40/60/80/100% movement speed each time Akali stealths, rapidly decaying over the course of 1 second
    • REMOVED RESISTANCE IS FUTILE Akali no longer gains bonus armor and magic resistance while in Twilight Shroud

Bird is the word.

"We're hoping to give some extra love for new players picking up Anivia, as they'll have a clearer understanding of how to use this cool chick. "
  • Flash Frost.png Q - Flash Frost
    • NEW STUNNING INDICATORS Flash Frost now has a cast indicator to show stun range
    • NEW STUNNING CLARITY Flash Frost now has an icy cloud around its particle to show stun range (only the Anivia player can see this)

So many bug fixes. Also some small buffs to Azir's base attack damage and attack speed.

"Gauging a new champion's release strength has traditionally been a difficult task, given we have to account for player learning curves, the landscape of the game and, in Azir's case, how that champion's ability coding holds up in millions of unique games (and game interactions). All of the above also plays into the next steps we need to take in helping (or toning down) that champion. With Azir, we saw some small changes we could take to help out his laning phase, but we're going to take it easier on anything larger until these fixes go through. "
  • General
    • BASE ATTACK DAMAGE 43 ⇒ 47
    • BASE ATTACK SPEED 0.556 ⇒ 0.600
  • Shurima's Legacy.png Passive - Shurima's Legacy
    • TWO AZIRS!? Fixed a bug where two Azirs were able to summon a Sun Disc from the same interactive clicker
    • NO SUN FOR YOU Fixed a bug where other players were able to target the Sun Disc interactive clicker with abilities (e.h. Lee Sin's Safeguard) or were told they could click on it and then couldn't and then became sad.
    • TACTICAL CLICKING Reduced the clickable size of the Sun Disc interactive clickers by 20%
  • Conquering Sands.png Q - Conquering Sands
    • SLACKING ON THE JOB Fixed a bug where moving inactive soldiers into active combat range with Conquering Sands would fail to activate their attacks properly, leading to 0 damage attacks
    • CONQUER FURTHER Fixed a bug where Azir's sand soldiers would fail to cross a wall if they were just a little short of it
  • Arise!.png W - Arise!
    • PRETTY SIGNIFICANT BUFF FIX Fixed a bug where multiple soldiers attacking multiple targets would often lead to soldiers incorrectly applying reduced damage. Reiterating here: this is a pretty big 'buff' fix.
    • THEY'RE BREAKDANCE FIGHTING Fixed a bug where dancing would break Azir's soldier's basic attacks
  • Shifting Sands.png E - Shifting Sands
    • NEW TAKE ME WITH YOU If Azir uses Shifting Sands on a soldier currently moving via Conquering Sands, he'll now join the soldier on a combined magical journey
    • I CAN'T TELL THEM APART Fixed a bug where Azir wouldn't shift to the correct soldier in certain situations
    • READY TO GO Fixed a bug where pressing E immediately after pressing W would occasionally not work. Feel free to W+E away now (or try W+Q+E for an even cooler combo)!
  • Emperor's Divide.png R - Emperor's Divide
    • IT'S COMPLICATED Fixed many bugs with Emperor's Divide. This ability should no longer:
      • Deal damage multiple times
      • Multi-bounce targets
      • Pin targets to walls
      • Fail to bounce targets to the far side of the wall
      • Not break channels
      • Break spell shields and still knock enemies back
      • And more!
  • Bug Awareness
    • SOON We're aware of a bug where Azir's Sun Disc currently does not ramp up in damage. We'll be fixing this in patch 4.19.

Small Ezreal buffs.

"See above. We're trying to give him some extra love so he can keep up in a modern game of League of Legends. "
  • Rising Spell Force.png Passive - Rising Spell Force
    • BUFF DURATION 5 seconds ⇒ 6 seconds
  • Mystic Shot.png Q - Mystic Shot
"NOTE: This change has already taken effect, but the tooltip hasn't been updated. We'll get to that as soon as possible. Thanks!"

Cannon Barrage now deals full damage in waves to everyone within the zone, rather than randomly dropping cannonballs on heads.

"Real talk: this change doesn't do everything for Gangplank in the long-term, but a consistency pass on Cannon Barrage was one we saw we could do in a self-contained change without fundamentally altering GP's playstyle. "
  • Cannon Barrage.png R - Cannon Barrage
    • IT'S HARD TO AIM A CANNON Cannonballs now fall in waves that damage the whole zone once per second. Individual cannonballs no longer have individual damage zones.
    • COOLDOWN 120/115/110 seconds ⇒ 125/110/95 seconds

W's damage has gone down, particularly at higher ranks. Also, sometimes we just want to talk about Kha'Zix.

"While it's true that Kha'Zix has been a tough bug to balance, we wanted to talk about our approach with him. If you're not interested in a long Kha'Zix context for a single change, feel free to move on. WARNING: this discussion's going to get a little complicated!
So. Kha'Zix has once again found a way to prosper as a high-priority assassin, but the popularity of a champion doesn't automatically translate to them needing a nerf. To us, when someone becomes popular in high level / competitive play, we see them as exhibiting symptoms of certain attributes that competitive players value: strength, overall effectiveness, and reliability. As such, we do keep an eye out for popular competitive champions, but our first goal is to understand if they're just powerful strategic picks in the current meta or if they're actually objectively better (or more reliable) than their peers.
In the case of Kha'Zix, Q was designed to be his main tool when assassinating targets, and it's important to maintain that relationship for game health / champion identity reasons. Right now, however, Kha's actually prioritizing W as a first evolution (and max rank), but he's still expecting to do all of his assassin-y things (note: without evolving or focusing on what should be his primary killing tool). We're fine with players opting for a W-first Kha'Zix, but this means he's gotta make some meaningful tradeoffs, like losing some offensive threat while gaining utility / poke. Unfortunately, this hasn't really been the case as we're still seeing Kha'Zix being very effective as an assassin while also getting all of the extra utility of evolved W.
What all of this tells us is one of two things: a.) The utility and strength of evolved W is too reliable in combination with Kha'Zix's base kit, so he can get the best of all worlds by maximizing his utility while also being a high-threat assassin. Or b.) Kha'Zix's evolved Q is too weak to properly use as a primary play pattern, so he's forced to max / evolve W to stay relevant in the game but doesn't really want to. We strongly suspect the first case is more true (and this is reflected in our change).
It's tough to justify a champion being 'too weak' if they continue to be a high-priority pick in games where strength and reliability are the most important traits. Final reassurance though: we do think Kha'Zix's play patterns are fairly healthy overall, so we're not planning to make any major changes in either direction, we just wanted to explain some of our thought processes as we work."
  • Void Spike.png W - Void Spike
    • DAMAGE 75/115/155/195/235 ⇒ 80/110/140/170/200

Occasionally relenting pursuit. This will have been the third time we've made a joke regarding Relentless Pursuit and no apologies will be made at this point in time.

"When we originally re-balanced Lucian back in patch 4.12, we were actually concerned with him being too weak in the laning phase (hah), and so gave him compensatory buffs to keep up. Since then, however, Lucian's gone on to be a premiere lane bully with access to a pretty solid late game as well. These changes should make Lucian think a little more about that aggressiveness in lane."
  • Relentless Pursuit.png E - Relentless Pursuit
    • COST 0 mana ⇒ 40/30/20/10/0 mana

Nunu & WillumpSquare.pngNunu

  • Absolute Zero.png R - Absolute Zero
    • ABSOLUTE CLARITY Absolute Zero's tooltip now shows the minimum damage it will deal


"Still not renaming it. Maybe in a future patch. Foot stab? "
  • Cutthroat.png E - Cutthroat
    • WHOOPS Cutthroat now properly grants assists

Rapid Fire's gives a smaller but more powerful buff in the late game. Tristana gets less attack speed per level.

"Apologies if we're repeating the same thing from 4.17 but we're looking for ways to give Tristana more moments of weakness. As another repeat: while these changes may not completely address that goal, we're hoping that by making Trist more dependent on Rapid Fire to deal damage, there will be clearer windows to engage or disengage against her."
  • General
    • ATTACK SPEED PER LEVEL +4% per level ⇒ +2.5% per level
  • Rapid Fire.png Q - Rapid Fire
    • DURATION 7 seconds ⇒ 5 seconds
    • BONUS ATTACK SPEED Now gives 30/45/60/75/90% attack speed ⇒ 30/50/70/90/110% attack speed


  • Siphon Power.png Q - Siphon Power
    • SORRY AD VIKTOR The bonus Discharge magic damage can no longer critically strike
    • BUGFIX Viktor's shield will now properly break when Viktor takes small amounts of damage


  • Nimbus Strike.png E - Nimbus Strike
    • WUJU STYLE? Nimbus Strike will no longer pick a secondary target if they're targetable but invisible due to Fog of War

Yasuo's base health and movement have been reduced. Remember that time we talked about taking more time to read the summary than the actual changelist?

"As hypercarry swordsman, Yasuo should make early game tradeoffs for opponents to capitalize on before he grows to his late potential. Right now, that isn't quite the case as Yasuo's quite strong in the early game, even in unfavorable matchups, in addition to scaling extremely well. These changes are to more specifically highlight Yasuo's early weaknesses, including being squishier if his passive isn't up and, more importantly, being more vulnerable to ganks if he's pushed up and doesn't have minions to dash through for his retreat. We'll be keeping a close eye on Yasuo with these changes, however, as having an early game weakness will almost certainly have an impact on his late game reliability."
  • General
    • BASE HEALTH 512 ⇒ 462
    • BASE MOVEMENT SPEED 350 ⇒ 340

  • SPLASH The following champions have received updated base splashes (click the portraits for the full image!):


"WARNING: Due to a bug, this change is currently not in effect (the tooltip is simply wrong, it's still 10%). We'll be looking to hotfix this when we can and will update the patch notes accordingly. Sorry!"
"With hypercarry marksmen running rampant in the mid to late game, we're returning a little more power to Randuin's Omen to give tanky dudes better itemization choices when fighting back. "

Featured Game Modes

"Our next featured game mode, Hexakill: Twisted Treeline, will be released later this patch! "

In-Game Announcement Banners

"In-game announcements received a visual update back in 4.16. We've read through your feedback and are making a number of tweaks and improvements aimed at making announcements cleaner and less intrusive. For clarity. "
    • CLARITY Announcements have been scaled down a bit and moved higher up on the screen
    • MORE CLARITY Increased the transparency of announcement background effects
    • EVEN MORE CLARITY Summoner names have been removed from some announcements for brevity. Killing spree callouts retain them for bragging purposes.

In-Game Options Menu

Volume Sliders

"With our new audio engine up and running, we gained the ability to tie a lot of existing audio effects to new volume sliders. We're implementing a slider for ambient sounds, as well as the often-requested ping slider. These new options are meant to give players more control over their audio experience in League of Legends.""
  • Added a new volume slider for pings
  • Added a new volume slider for ambience (ex. red buff's campfire and the wind on Howling Abyss)

Removing Pando Media Booster

" As we discussed a few weeks back, we’re removing Pando Media Booster from the installer and patcher this patch. Don’t know what we’re talking about? Pando is a defunct 3rd party peer-to-peer service we previously used to help players download new files faster.
If Pando Media Booster is on your computer, you’ll see a popup once you launch League of Legends that’ll prompt you to remove Pando from your computer with a single click. We no longer use Pando’s services in our releases, so we recommend removing it. "
  • Pando Media Booster has been removed from the installer and patcher
  • Players with Pando Media Booster on their computers will be prompted to remove it with a single click

Suggested Players

  • PREMADE FACILITATION The Suggested Players invite list in premade lobbies now recommends friends of friends who are currently online and available for a game


  • (Fixed during 4.17) Resolved a significant source of crashes introduced last patch which predominantly affected Mac players. This won't solve every crash, but we remain committed to fixing as many issues as possible in every patch.
  • A lot of Azir fixes. Head back up to his section for the full list!
  • Garen's R - Demacian Justice will no longer cancel itself if the target enters the fog of war while Garen is mid-cast
  • Undoing a Ruby Sightstone purchase no longer interferes with Sightstone's ability to place wards
  • Abilities blocked by spell shields no longer proc life steal or spell vamp
