LoL Patch 12.23 Notes: The First Patch of the Preseason 13

LoL’s first patch for the preseason is a massive one with multiple champion adjustments, jungle and ARAM changes.


The first patch of the Preseason 2023 is over. There were many changes in patch 12.22, with the main focus of the last three weeks being on Ravenous Hydra and multiple other tank items. So it is very expected that we are seeing changes to some of these items. First of all, Ravenous Hydra is losing nearly all extra Omnivamp it gives through its stacks, which was a big point of contention in the community. And while most tank items such as Jak’Sho and Heartsteel are staying the same, Sunfire Aegis will see some buffs.

There are also three massive champion adjustments in the patch (Zeri is counted as Buff but it is still as big). Kassadin’s changes in the smaller side, with only his Q (Null Sphere) and E (Force Pulse) changed. But even these small changes should do a significant difference in his laning phase, especially against opponents who don’t rely on abilities, which tend to be AD champions that counter Kassadin. Mundo, on the other hand, will see changes to his entire kit. But these are primarily number-based, not updated skills or anything, with the purpose of lowering his damage so he can scale up to be an unkillable late-game tank.

Then there is Zeri. Ever since her introduction in January, the Spark of Zaun has been the bane of the balance team’s existence. She went back on forth between being too overpowered to useless for a while. But after she dominated pro play at the end of Summer, Riot gutted her so she wouldn’t be showing up at Worlds 2022. Now with the changes in patch 12.23 Zeri will have a lot of movement speed, as it's her identity, but she will sacrifice some of her damage and range for it. Riot is also making her Ultrashock Laser (W) physical damage so she will not be a mixed damage champion.
