League of Legends patch 12.7 notes: Jayce & Zeri nerfs, Yasuo & Yone buffs, Arcana skins

League of Legends patch 12.7 is here, and Riot are promising big changes. With MSI on the horizon the developers are shaking up the meta ⁠— pro staples like Jayce and Zeri are on the chopping block, while Ionian brothers Yasuo and Yone are getting buffed. Here’s the full patch notes.

After a couple of small updates, Riot are going all-out in League of Legends patch 12.7.

The imminent start of MSI 2022 is the big pressure point as the developers look to tone back some of pro play’s most powerful picks across Spring. That’s why you’ll see the likes of Jayce, Lee Sin, Ryze, and Zeri in for nerfs despite not doing too hot in solo queue.

Similarly, off-meta picks like Lillia and Karthus in the jungle, as well as Gangplank and Wukong in top lane, are getting some help. Oh, and Yasuo and Yone too ⁠following the Immortal Shieldbow nerfs.

And, as per usual, there’s a new host of cosmetics as the fan-favorite Arcana skinline returns with five new champions getting the tarot-inspired skins.

Let’s unwrap what’s coming in League of Legends patch 12.7, including the full patch notes.

What’s changed in LoL patch 12.7?

Zeri locked in for nerfs ⁠— again

In case you’ve been counting, Zeri has found herself facing her fifth set of nerfs since her release just five patches ago. In LoL patch 12.7, Riot are giving the Spark of Zaun another pass to try and reduce her pro play impact.

While her win rate has dropped to 47.64% in ranked play, she still boasted a 57.29% win rate across the last two updates in the hands of professionals (114 wins in 199 games globally).

The nerfs are targeting her Bruiser build, Riot noted, but will still be an overall nerf for her other pathways including Crit and AP. This includes reducing her base stats, her Q and W base damage, as well as nerfing cooldowns on E and her ultimate early but scaling better late.

While the Zeri changes are the biggest, Jayce, Lee Sin, Rengar, and Ryze are also facing nerfs as the first international League of Legends event of 2022 nears.

Yep, more Zeri nerfs. Her fifth set in two months.

Yasuo & Yone get buffs as Immortal Shieldbow nerfs hit hard

They might be a threat in your solo queue games, but Yasuo and Yone have been struggling since Riot nerfed lifesteal in LoL patch 12.6. So, the Ionian brothers are getting some help in the lead-up to MSI in LoL patch 12.7.

Yasuo is getting some bonus base health and a shortened ultimate cooldown early, while Yone will better scale with a similar ultimate change ⁠— just for late game.

The top lane is also facing a meta shift with Gangplank, Gwen, Pantheon, and Wukong also being buffed. So too the jungle, thanks to Lillia and Karthus changes. They’re nothing ground-breaking, but it should increase champion diversity on the world stage.

Arcana skins return

Arcana has quickly become a fan-favorite skinline in League of Legends. The tarot-inspired cosmetics, with plenty of reds, golds, and black tones, are known for having some of the flashiest animations in the game.

Five new champions are joining the existing four in LoL patch 12.7, making a roster of nine. Those are:

  • Ahri
  • Hecarim
  • Rakan
  • Ryze
  • Xayah

There will be no Arcana Prestige skins in this release, however.

Dexerto can confirm each Arcana skin will launch with eight chromas, ranging in various colors from deeper reds to shifts to blues and greens. As for skin costs, they’ll be available for 1350 RP a pop.
