The first patch since the LoL 2023 Preseason launched will go live next week.

With every new season, there is always a big need for balancing. Nearly every champion in the game got affected by the changes in the preseason, not the mention the champions who were already in need of some adjustments. So, it is not surprising that we got a massive patch preview when Riot’s Summoner’s Rift design team lead, Matt ‘Phroxzon’ Leung-Harrison, tweeted what they have in store for the fans.

Starting off, there are some system changes. Two very strong items, Ravenous Hydra and Sunfire Aegis will get touched in order to give some classes their item diversity back. Players will also see some more jungle changes to further balance the massive 12.22 changes. With the LoL patch 12.23, junglers will clear their camps faster and will get more XP for it but in return, they will heal for a little bit less after killing a camp.

Then the big champion adjustments, on top of the usual nerfs and buffs. Three champions will see some big changes to their kits. Starting with Kassadin, the smallest of the adjustments, whose Force Pulse (E) has changes to its stacking mechanic thus giving him an arguably easier laning phase. Next is Dr. Mundo who lost some of his bAD ratios in favor of more healing in his kit.

Last but not least, Zeri is back after Riot left her to die during Worlds 2022 patches. Almost every part of the speedy ADC will see some changes, and we will have to wait and see if these can fix her problematic nature or not, but they are very simple in essence. 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.
