League of Legends Patch 12.23 Notes - Release Date, Winterblessed Skins, and More

Here’s where we’ll explain everything that’s changing and being added with League of Legends Patch 12.23.

LoL patch 12.23 is now available on live servers. A look at its patch notes reveals its release date alongside the addition of new skins from the Winterblessed line, and more.

Riot Games pushes out regular updates for its popular MOBA, and having a patch schedule nearby is necessary to keep track of when the next one’s due out. The LoL patch 12.23 release date was set for Wednesday, December 7, which is when the changes that make it through testing hit live servers.

League of Legends Patch 12.23

On the PBE, players could try out the following 7 new skins: Winterblessed Diana (1820 RP), Winterblessed Warwick (1350 RP), Winterblessed Shaco (1350 RP), Winterblessed Swain (1350 RP), Winterblessed Zilean (1350 RP), Winterblessed Zoe (1350 RP), and Prestige Winterblessed Warwick.

The LoL 12.23 maintenance schedule is always revealed closer to launch. Usually, it takes about 3 hours for patches to be deployed across different regions. Checking our League of Legends server status article is a good way to keep yourself informed on server downtime caused by patch deployment or other reasons.

A series of additional changes will be pushed to the live game before League of Legends’ patch 12.23 arrives, introducing a handful of buffs and nerfing Ravenous Hydra.

According to Lead Designer Matt Leung-Harrison, we can expect “a lot more polish to come in 12.23,” following the deployment of the preseason’s sweeping changes.

The MOBA’s jungle is also getting some tweaks, the first of which lower early clearing speed by ~5-7%, slightly increase late game sustain, and adjust leashing to offer more room to kite while clearing.

Adjustments are also planned for how works leashing, offering more room to kite while clearing, as well as champion select clarity.

With the League of Legends 12.23 patch preview revealed, we now know that, aside from several changes to the jungle, champions like Amumu and Zac are slated to be buffed, while others, like Trundle or Mordekaiser, are about to be hit by the nerfhammer. Zeri is also in line to receive several changes.
