League of Legends patch 12.23 notes: More jungle changes, major tank buffs

Trundle in League of LegendsRiot Games

LoL patch 12.23 is on its way as Riot balances the Season 13 changes. First cabs off the rank are the jungle and tank champions, with both getting significant overhauls to stabilize the meta ahead of the January ranked launch: here are the patch notes.

League of Legends Season 13 has arrived with a bang. With the preseason update going live on LoL patch 12.22, players are slowly but surely getting used to all the new changes.

Across the first couple of weeks there’s been a couple of outliers though. Top lane duelists are incredibly strong with new items and adjustments to the role, leaving tanks in the lurch. Similarly, the jungle is a bit broken with exploits and balancing issues.

Those are the two changes at the top of Riot’s list for LoL patch 12.23 as they look to stabilize the meta over the holidays and ahead of January’s ranked season launch. Here’s what you need to know about the upcoming December update.

What’s changing in LoL patch 12.23?

Jungle rebalance fixes funnel issue, leashing

With the myriad of jungle changes, there were bound to be issues early in Season 13. LoL patch 12.23 is a first pass at trying to solve all of them ⁠— exploits, general balancing, and all.

Riot is aware of the mid lane funnel strategy revolving around multiple champions purchasing the new jungle pets, and have got a fix in place for the December update. More broadly though, jungle gold will be reduced while experience will be increased slightly.

Specific camps will have reduced auto attack ranges, while all camps will have new leash ranges to be more forgiving to champions who have to kite and move.

As for individual junglers facing changes, Dr. Mundo is getting a swathe of jungle-centric buffs. Dominant forces Lillia, Shyvana, and Trundle will be nerfed.

Tanks get love despite Heartsteel dominance

Tanks have suffered a bit at the start of League of Legends Season 13, especially in the top lane. With gold and experience reshuffling across the map, and new items favoring fighters and duelists, some tanks have struggled to get a foothold.

While Heartsteel is still a problem, Riot is ignoring it somewhat to try and target individual tank champions with buffs. Amumu, Cho’Gath, Malphite, Maokai, Sion, Tahm Kench, and Zac are the main targets to start, but developers are keeping an eye on things.

“If we observe negative meta effects as a result of Heartsteel or Tank meta, then we’re going to react, but will let it play out a bit for now to stabilize,” Leung-Harrison said. “Tanks getting buffs [this patch] have dropped 2-3% [in winrate].”
