The Curses must be stopped.

League of Legends Arena has returned with a mighty bang this month with thousands pouring in to play the limited-time mode, and with that, Riot Games is preparing an extensive Patch 13.23 change list⁠—focusing on Augments—to keep the waning 2023 metagame under wraps.

When will League Arena Patch 13.23 go live?

League Arena updates are bundled into League-proper patches, so these changes will go live in the limited-time mode on Wednesday, Nov. 22.

Things will begin staging for the usual League update around 10am AEDT and then roll out across all major regions for the game through that same day. For all the other major League regions, here are key patching times:

  • 3pm PT (NA)
  • 5am GMT (EU West)
  • 3am CET (EU North East)
  • 8am KR (Korea)

Expect several hours of League server downtime on Wednesday.

What’s changing in League Arena in Patch 13.23?

The first big League Arena patch since its glorious return is all about finding the best  balance for everything, with five item changes, a mighty 23 Augment tweaks, and a horde of champion buffs and nerfs in the works. There is also at least one Cameo adjustment shipping this update.

Riot line up “a ton” of champ changes

League Arena will be getting a major metagame shuffle once this update goes live, with Riot MadnessHeroo promising a bucketload of Mage and Fighter changes. 

These haven’t been locked in quite yet, but the devs are picking through the code numbers to figure out exactly what they want to hit first up.

Outliers, especially Curses, warping the metagame

The majority of Augments and items hit in this patch, including extraordinarily powerful selections like Hellfire Hatchet and Plagubearer for items and Augments respectively, have been deemed simply too overpowered.

In a bid to reign in the metagame and especially these “outliers” before the 2024 League season hits, Riot is happy to ship out a massive list of changes.

In particular, the Curse Augments are very much on the dev team’s radars, with MadnessHeroo admitting the picks are “pretty warping” right now. They are getting some changes in this update, but Riot is already investigating other ways they can handle them in the future too.

I’ve put together a full list of changes below. Remember, these are still being tested on the League PBE, so not every single one may land on live servers.
