League of Legends 4.18 sees the release of Sion; full patch notes here

More of a small maintenance update

League of Legends has received patch 4.18. While there's not a whole lot of balance changes in this patch, it does see the launch of one of the game's largest champion updates to date: Sion, the Undead Juggernaut, who recently underwent a tremendous overhaul.

In addition to Sion's release, 4.18 has a bunch of bug fixes for Azir, a Gangplank buff, the removal of Pando Media Booster, a Smart Ping volume slider, and phase 2 of the mass champion texture rebalance.

Riot says to think of this patch "as more of a small maintenance update" as we look forward to the World Championships. "Definitely some bigger things to come in the future, so stay tuned," Riot teased.

Now on to the 4.18 patch notes:

Champions

Sion

"Sion, the Undead Juggernaut, will be released with the launch of 4.18."

Azir

"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."

BASE ATTACK DAMAGE 43 ⇒ 47
BASE ATTACK SPEED 0.556 ⇒ 0.600

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.g. 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%

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

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

E – Shifting Sands

NEWTAKE 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)!

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!

Gangplank

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

These are just a few of the champion tweaks. Check out the full champion balancing and bug fixing changes in patch 4.18 here.
