Preseason is coming.

League of Legends players might be pulling their hair out if their LP is suddenly dropping because the preseason is coming.

Patch 12.21 is the final patch of the regular season, with the next patch dropping on the live servers on Nov. 16. With the final patch of the 2022 season, Riot Games’ balancing team is tweaking Miss Fortune’s, Bel’Veth’s, and Blitzcrank’s numbers largely because of their incredibly dominant performance in high Elo. On the other hand, the devs are trying to bring Ahri, Corki, Malzahar, and Xin Zhao back to relevance with a series of buffs. And most importantly, Patch 12.21 is bringing the already amazing K’Sante to League on Nov. 3. 

All things considered, Patch 12.21 is a relatively small patch addressing only minor tweaks so that the season ends with a bang, not with a whimper. So let’s take a look at what exactly will await us in League these days, besides the Pride of Nazumah himself.

Here are the full League Patch 12.21 notes.

K’Sante, the Pride of Nazumah, is making his debut in League on Nov. 3. Designed as an incredibly durable top laner that can easily catch up with immobile targets disrespecting him, K’Sante will for sure shake up the meta in its final days.

If you want to prepare for K’Sante’s release and learn his abilities before he hits the live servers, you can find all his abilities here.
