Read ahead for the League of Legends Patch 13.1b Notes, the update that will be shipped instead of 13.2 due to the recent hacking attack on Riot Games.

“Our dev teams have been working hard over the last couple of days and have a hotfix prepared to be deployed on Thursday (1/26) that will have most of the content for both LoL and TFT.

We know this is disappointing but we believe we will have things repaired near the end of the week, which will allow us to remain on our regular patch cadence going forward.

Again, there is no indication that any player data or personal information was compromised. Thank you so much for your patience and understanding.”

The Ahri ASU has also been pushed back to Patch 13.3. Aurelion Sol's Comprehensive Gameplay Update (CGU) has also been delayed with no confirmed release date, according to the CGU's producer Rob “Riot King Cobra” Rosa.

“Since the team wants to hear your feedback before he launches in two weeks, I’m spinning up this thread anyways and including some videos of Aurelion Sol’s abilities for his Ashen Lord and Storm Dragon skins along with detailed information about his base stats and abilities,” said Riot King Cobra on the Reddit post. “We've got about a week before we have to lock any proposed changes for his release, so I'll be monitoring common themes in this thread to share back with the team for possible adjustments.”
