League of Legends patch 12.12b notes: Katarina & Shaco buffs, Bel’Veth nerfed again
League of Legends patch 12.12b is ready to roll out: Riot are reverting some big changes from the previous update to Katarina and Shaco, and pushing ahead with further nerfs to nuisances like Bel’Veth and Zeri. Here’s the full patch notes.
With the holiday break approaching, Riot are getting in with some changes to tide over League of Legends players in LoL patch 12.12b.
The developers are focusing their attention primarily on the bot lane with more than 70% of the changes affecting champions who predominantly reside on the south side of Summoner’s Rift. This includes toning back pro meta staples, and giving some power to fringe picks affected by the durability update.
New release Bel’Veth is also back in the headlines, and Katarina and Shaco are the big winnersfollowing their nerfs just a week ago.
Catch up on all the LoL patch 12.12b notes below.

What’s changing in LoL patch 12.12b?
Katarina and Shaco buffed after item changes hit hard
While Katarina and Shaco weren’t too prevalent in the League of Legends meta,their LoL patch 12.12 changesnuked them from relevancy. Riot tried to push the two champions towards more healthy builds, and it backfired completely.
The developers are backtracking slightly to give each champion a bit more of a fighting chance. Katarina’s scaling is being improved — both with AD and AP — across basically all of her abilities. Shaco is receiving similar treatment, although with more emphasis on AD.

It’s not a total revert of the update both champions received in the previous update, but it will at least make them not totally unplayable.
Bel’Veth nerfed again as win rate creeps towards 55%
Players are slowly getting the hang ofnew Void jungler Bel’Veth, and the Lavender Sea is starting to take over Summoner’s Rift. While she struggled in high elo on launch, she nowboasts a near 55% win rate across all ranks— enough for Riot to ship more nerfs.
Her scaling is the main target with nerfs to her attack damage and health growth, lifesteal off of her E, and bonus AD scaling on her ultimate. Her E cooldown is also being upped in the late-game.
These changes should help bring her down to around 50% win rate, which is Riot’s ultimate goal. Wukong is the other jungler facing nerfs in the update with his E doing less damage to monsters and his ultimate cooldown being increased early.
Plenty of bot lane changes: Senna, Tahm Kench, Yuumi, Zeri, more
As the League of Legends bot lane meta has evolved withthe durability update, plenty of top picks are being nerfed to bring some more diversity into the role.
Popular bot lane duo Senna and Tahm Kench are being nerfed. Senna will have a bit more damage on her Q later on but traded off with less utility from W. Tahm Kench will also be slightly less oppressive in the late game with less bonus health damage from his passive.
Zeri’s movement speed is being cut again, Seraphine’s scaling is being reined back in, and Yuumi will no longer get bonus range on her passive auto attack to collect the shield.
On the flipside two champions are being buffed: Caitlyn and Leona. Caitlyn’s bonus damage on passive is being increased with lower damage on W to compensate — which should be more reliable for the Piltovan sniper — while Leona’s passive damage is also being upped slightly.
