Patch 13.12 is coming soon to League of Legends.

Patch 13.11 was a follow-up to some outliers of League of Legends. That patch introduced many champion and item changes. However, it did not move the needle too much in terms of strong champions, as Ivern got added to that list.

The patch introduced the Rell mini-rework, buffs & nerfs to items and champions, buff sharing, and some ARAM adjustments. Since the patch landed, Rell has received a pretty big hotfix, which has made her a bit too strong. Overall, Patch 13.11 did not change the meta a whole lot from Patch 13.10.

The reasoning behind Patch 13.11 being smaller was to give time to settle the dust so that the balance team could evaluate what to address.

Thus, Patch 13.12 is going to be a fairly big patch based on the list provided in the patch preview. There are multiple champion buffs & nerfs, along with item changes. There is a lot coming to Patch 13.12. Despite all the mishaps, the balance team managed to get the proper preview out.

Let’s talk about all the changes that are coming to Patch 13.12.

LoL Patch Notes 13.12

The dust has settled, and Riot is now coming in with a big patch. Buffs are tailored towards weaker champions and make itemization optimizations for Kai’Sa. Meanwhile, the nerfs mostly to Pro Play champions like Zeri, Yuumi, Milio, and more. Items are getting some changes, as well as some fairly minor adjustments to the Duskblade of Draktharr.

Let’s jump straight into all of that.

Champion Buffs

There are eight champions receiving buffs in Patch 13.12. From what we know thus far, Ashe is getting both Support and ADC buffs, while Kai’Sa is getting some Evolution Breakpoint buffs to accommodate the item changes in Patch 13.10. Many struggling champions, like Sivir, Ryze, etc., are getting some buffs. Here is the list of buffs.

Ashe

Many of her abilities are getting a damage buff that will help in both the ADC and Support roles.

Lucian

The passive is changing to fit more with other Support pairings.

System Buffs

A few items are getting buffs with a list of four of them struggling in the current patch. Also, mid lane gold is getting buffed though we have no idea how much of it is getting increased. Here are the system buffs coming soon.

Immortal Shieldbow

A bit more lifesteal is being added to the item.

  • Lifesteal: 7% >>> 10%.

Mid lane Gold

Gold is being added back to mid lane minions to give back some of that economy that was taken from players.

  • -1 Gold Change Reverted From Mid Lane Minions.

Phantom Dancer

A little more attack speed is being added to the item.

  • Attack Speed: 30% >>> 35%.

Statikk Shiv

The passive is being improved to deal more damage with each proc.

  • Energized Damage: 80 – 190 (level 7-18) >>> 100 – 180 (level 6-18).

System Nerfs

Like buffs, many items are getting nerfed, with the likes of Ardent Censer and Imperial Mandate on the list. While the items nerf are the highlight, Red Buff and Overheal are also getting nerfed. Here are the following nerfs coming soon.

Ardent Censer

The On-Hit damage is being made constant at all levels to stop the hyperscaling on the item.

  • On-Hit Damage: 15 – 30 (level 1-18) >>> 15.

Bloodthirster

Price is being increased slightly to make it a later buy.

  • Gold Cost: 3200 >>> 3400.

Galeforce

Ever since the changes, Galeforce has been a problem and Riot is coming in with another swoop of changes.

  • Attack Damage: 55 >>> 50.
  • Active Damage: 150 – 350 (+ 200% Crit) >>> 150 – 350 (45% bonus AD).

Rapid Firecannon

Energized damage is being reduced to balance the item.

  • Energized Damage: 60 – 140 >>> 60.

Red Buff

Finally, Red Buff is getting some nerfs because the buff has proved too valuable at times.

  • Damage: 6 + (6 per level) >>> 6 + (4 per level).
  • Slow: 10/15/25% >>> 10/15/20%.
  • Health Regen: 1/3/9% Maximum HP >>> 1/3/5% Maximum HP.

System Adjustments

The only system adjustment is Duskblade for certain interactions. It is simple bugfix to fix the interaction for champions like Katarina.

Skins

Five skins are coming to Patch 13.12 as we are getting a new Mythic skin line. Shan Hai Scrolls is also making a return with four skins. Here are all the skins.
