League of Legends patch 12.15 is on its way, and the big topic is energy champions. Ionian favorites like Zed and Shen have struggled post-durability update, and Riot wants to help them. Sivir, Gwen, and Taliyah are also being nerfed again: here’s the full notes.

There’s only a few patches between now and Worlds 2022, and Riot is starting to hone in on the meta with LoL patch 12.15.

The developers have earmarked some oppressive picks requiring action: Sivir, Gwen, and Taliyah are once again in the nerf column after their recent dominance. However, there’s also some buffs planned that could bring a subclass back into the fray: energy champions.

Plus there’ll be a new range of Monster Tamer skins as part of the release as the Star Guardian event nears its end.

Here’s what you need to know about League of Legends patch 12.15, including when exactly the update will drop.

What’s changing in LoL patch 12.15?

Energy champions rework following durability update

The durability update completely flipped League of Legends on its head, and the aftermath is still being felt out. Healing has been a big priority for Riot in the patches since, but in LoL patch 12.15 their focus is shifting a bit towards energy champions.

With fights dragging along for longer, energy champions are finding themselves running out of resources much quicker than anyone else. Riot are pushing things along with small buffs to all of them to even things out. This will include: Akali, Kennen, Lee Sin, Shen, and Zed.

Akali and Shen will have increased energy refunds on their W and E respectively, while Zed and Lee Sin are having their base energy costs cut.

Kennen will be an outlier in that he won’t get a direct energy buff: “We like where Kennen’s energy costs are, so we’re buffing something else instead,” developer Matt ‘Phroxzon’ Leung-Harrison told players.

More nerfs for meta picks like Sivir, Gwen, and Taliyah

LoL patch 12.15 will include more of the same balancing updates for meta picks. Names like Sivir, Gwen, and Taliyah have cropped up in the patch notes a lot recently, and they’ll continue to do so in the run into Worlds.

The trio of champions will be joined by Master Yi (also targeted after his Meditate rework), as well as the recently-buffed Qiyana and pro play staple Kalista.

None of the nerfs are too serious. They range from base stat changes (less AD for Kalista) to cooldown adjustments (Taliyah and Sivir). The update is more nudging champions towards the middle rather than swinging them too far out of the meta.

For buffs, five other champions are in Riot’s sights: Lillia, Singed, Rammus, Leona, and Thresh. This will lead to some shifts in the support and jungle meta, but nothing too drastic as Riot looks towards bigger preseason changes for all the roles.

Sivir nerfs are still coming in thick and fast following her mid-scope update.

Not much has changed from Phroxzon’s preview set of notes other than Silvermere Dawn’s HP buff being reverted and the First Strike Qiyana bug getting fixed. This bug allowed Qiyana to proc First Strike twice, making her a terror in solo queue and making this bugfix a big nerf to the champion.
