League of Legends update 25.12 early patch notes bring Rammus rework

LoL’s 25.12 patch preview is here, with the big pull being some huge shifts to Rammus aimed at making him a more viable jungler who’s about more than just countering basic attack champions.

There are, of course, many other changes planned. Phroxzon has released a full preview detailing which champions will get changed, with this update being pointed exclusively at champion changes so far. After 25.11’s magic item-focused patch, the devs are honing in on champ balance ahead of MSI 2025.

There are a ton of jungle-focused updates, ones meant to bring characters like Lee Sin and Nidalee back into the meta ahead of MSI. After all, these are some of the most fun and skill expressive jungle champions to watch. It should come as no surprise that Riot wants to put them in a better spot before one of the year’s biggest internationals.

Here’s what we know so far about League of Legends patch 25.12.
