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

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."

Gangplank

R – Cannon Barrage

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