League of Legends Patch 9.12: Full notes and updates

Brought to you by IKON, challenging you to share your greatest game moments and win amazing prizes.

Patch 9.12 hit Summoner’s Rift this week and it brought with it a slew of champion changes that could have a huge impact on League’s meta.

Most notably, Sylas, Ryze, and Yuumi have all seen massive changes to their kits, and Mordekaiser received an entirely new look and abilities to give some more oomph to his playability. Additionally, three new Dark Star skins have made their way to the Rift for Jhin, Karma, and Shaco.
