League of Legends Patch 12.23 Notes: New Changes, Release Date, and More

The Patch 12.23 preview is out, as many changes are on the horizon for League of Legends, including more jungle changes, new mini-reworks, and more.

Preseason 2023 continues in League of Legends as Riot keeps changing parts of the game. Their philosophy of frequent patches has kept the game balanced and fun for the general players to enjoy.

All the preseason changes started with Patch 12.22. That patch brought in an immense number of changes. The changes include additions like new items like Heartsteel, changes to the jungle, and many others. All these changes are about making the game progress into the next season.

The litany of changes made shockwaves in the games. The jungle changes were cataclysmic with jungle pets, leashing changes, etc. After that, there were many item changes and additions, like bringing back Rod of Ages and the introduction of the infamous Heartsteel. Lastly, there were a bunch of champion changes, including many for ARAM.

Patch 12.22B brought in some mid-patch changes to get some small buffs to balance things out. The buffs to Jak’sho, The Protean, Rod of Ages, and Radiant Virtue did wonders, while some smaller changes were done to champion.

However, the patches created more problems, such as bugs and balance issues. The Neeko bug is amongst the latest bug that has come out and has been fixed. Regarding balance issues, Ravenous Hydra is still a problem, while many tanks are still struggling. There is still a lot of work for Riot to do.

Riot Phroxzon has released the new preview for Patch 12.23 and what changes to expect. Many of the changes are eye-catching, and some people started talking about these changes coming down the pipeline.

A lot of the changes are targeting balance changes, incoming mini-reworks, system changes, and jungle balancing.

Now, Patch 12.23 has been previewed, and we now know what changes are coming. Hence, without further ado, let’s jump right into it.

LoL Patch 12.23 Notes

Mini-Reworks

There are a bunch of mini-reworks coming. The information about it has been out for a while but let’s recap all the mini-reworks coming in League of Legends.

Dr. Mundo

The Madman of Zaun, Dr. Mundo, is getting a mini-rework. We had an article covering this a while back, so check that out. The changes are significant as Riot is changing how the champion works. The power on the champion is being shifted around, so it is not exactly a buff.

However, this will still be immense for the champions. Regardless, these are the changes we know that are coming to Dr. Mundo.

Kassadin

The Void Walker, Kassadin, is also getting a mini-rework. He is not getting a lot of changes, but it will cause people to adapt how they play Kassadin. We already did an article on the changes. Here is a recap of that.

Tahm Kench

The River King, Tahm Kench, is getting some love from Riot as well. This time, Riot wants to make him into an AP Bruiser. It is an interesting pivot considering that Tahm Kench got a rework last year. Thus, this mini-rework is designed to change how players play the River King. Let’s recap the changes coming to Tahm Kench.

    • Shield Duration: 2.5 seconds After Devour Ends >>> Unlimited but decays by 200 per second after Devour ends until the shield is gone.

The Spark of Zaun, Zeri, is the last champion to receive a mini-rework. It was much needed, considering how Zeri has been tanking in the win-rate area of League of Legends. It was talked about in another article.

Jungle Changes

As Patch 12.22 was a game-changing update for the jungle, there were bound to be a few problems. Riot has identified some of those issues and is going to fix them. The jungle changes have been divided into a few categories to target different aspects of it. Let’s talk about all the changes coming to the jungler in Patch 12.23.

General Jungle Changes

These are the changes that affect the overall jungler and are not on specific camps. All the changes are geared to balance the jungle and improve the feel of the role. Treat gold is being changed because junglers are getting a bit too much gold, and the experience multiplier is being buffed to compensate for the experience nerf in Patch 12.22. Thus, here are the changes coming to the jungle:

  • Base True Damage: 20 true damage >>> 16 true damage for pets.
  • After the first pet evolution, consume two bonus treats for killing a large monster and get all the benefits.
  • Native 20% Damage Amplification no longer works on Epic Monsters (Baron, Dragon, Rift Herald).
  • 10% of Bonus Armor/Magic Resist is converted to true damage for damage dealt by pets.
  • Bonus HP Ratio: 4% >>> 3%.
  • Monster Kill Health Per Level: 3 HP >>> 6 HP.
  • Monster Kill Mana Per Level: 2 Mana >>> 4 Mana.
  • Treat Gold: 50 gold >>> 35 gold.
  • Experience Multiplier: 1/1/1.025/1.075/1.15/1.15/1.25/1.25/1.35 levels 1-9 >>> 1/1/1.025/1.075/1.2/1.2/1.3/1.3/1.45 levels 1-9.

Specific Monster Changes

This part of the jungle changes is geared towards making monster-specific adjustments. Here are the following changes coming to the individual camps.

  • Gromp Auto Attack Range: 175 >>> 150.
  • Large Razorbeak Auto Attack Range: 300 >>> 200.
  • Leash range centers have been offset for Camp Spawn Locations giving more space for Champions to move and kite.

Mosstomper (Green Pet)

The green pet has been deemed to be unbalanced by Riot, so they are going in to reduce the tenacity timer and change how the tenacity gained works.

  • Tenacity Buff Duration: 3s >>> 1.5s.
  • Tenacity Type: Item >>> Champion.

ARAM Rework

The ARAM Rework is coming out of this patch, as many players are looking forward to it. It has been covered by us a while back as we are getting Hexgates, more Terrain, and such in the Howling Abyss.


Champion Buffs

It’s time to move on to the other changes of the patch. Let’s start with the Champion Buffs that are coming, barring the mini-reworks listed above. Tanks are getting small buffs to compensate for the low win rates since the last patch. Other than tank changes, Blue Kayn is getting some love. Here is the list of champions listed to receive buffs.

Amumu

The Sad Mummy is getting a bunch of stuff across the board ranging from more Health to more damage in his kit. His Bandage Toss takes a little cost hit to make sure Amumu is not given too much.

Shadow Kayn

Kayn is getting a buff to his Shadow (Blue) form. It has been struggling for a while. So to reinforce its identity, more damage and a little more sustain are being given to the neglected assassin.

Champion Nerfs

A few champions are slated to receive some nerfs. Yuumi is yet again on the nerfs list while junglers like Mordekaiser, Lillia, and Trundle are taking a few hits. Other nerfs include changes to Syndra and Shyvana. Here is the list of champions receiving a nerf.

Lillia

Her Q damage has been a bit too much so that is taking a little hit. Overall damage is reduced but early damage is slightly increased.

  • Q – Blooming Blows
    • Base Damage: 70-190 >>> 80-160.

Mordekaiser

Mordekaiser jungle has been a menace and so Riot is reducing his effectiveness in the role.

  • Passive – Darkness Rise
    • Procs on all monster hits >>> Procs on large monster hits.
    • Monster Cap: 180 at all levels >>> 28 – 164.

Shyvana

Her E does a bit too much damage so that is taking a hit.

  • E – Flame Breath
    • On-Hit Damage: 3.5% of target’s Maximum HP >>> 3% of target’s Maximum HP

Syndra

Syndra’s damage has been a problem so Riot is coming down on it.

  • W – Force of Will
    • Bonus Damage: 15% (1.5% per 100 AP) >>> 12% (+2% per 100 AP)
  • E – Scatter the Weak
    • AP Ratio: 55% AP >>> 45% AP.
    • Cooldown: 15 seconds >>> 17 seconds.

Trundle

The Troll King has been oppressive with his clear speed and really becomes a force in fights. Thus, some of that strength is being taken away to balance things out.

  • Base Stats
    • Attack Speed: 0.67 >>> 0.6.
  • R – Subjugate
    • Damage based on target’s Maximum Health: 20/27.5/35% >>> 20/25/30%.

Yuumi

The cat is being dampered with cooldown and root duration nerfs.

  • Passive – Bop ‘N’ Block
    • Cooldown: 14-6 seconds (based on level) >>> 18-6 seconds (based on level).
  • R – Final Chapter
    • Root Duration: 1.75 seconds >>> 1.25 seconds.

System Buffs

Sunfire Cape is the only item slated to receive some buffs. It seems that the item is still struggling to find its place as a Legendary item after being downgraded. Riot is trying to get a balance down for the item for versatile uses.

Sunfire Aegis

  • Combine Cost: 1000 gold >>> 900 gold.
  • Total Cost: 2800 gold >>> 2700 gold.
  • Health: 400 HP >>> 500 HP.

System Nerfs

Ravenous Hydra makes its way into another nerf list, being the only one in this patch. It has been running rampant in the game, with both the win rate and play rate skyrocketing. Riot is going to bring it down to make it a lot less overpowered.

Ravenous Hydra

  • Omnivamp on Full Stacks: 4% >>> 0%.
  • Splash Damage (Melee/Ranged): 60%/30% >>> 50%/25%.

Skins

The Winterblessed skin-line is coming to League of Legends as the roster for the cosmetics includes Winterblessed Shaco, Winterblessed Swain, Winterblessed Warwick, Winterblessed Zilean, and Winterblessed Zoe. Winterblessed Diana is the headliner as Diana receives her first Legendary skin of League of Legends.

The skin release will also include a Prestige version of Winterblessed Warwick and the much-hyped Ashen Graveknight Mordekaiser, an exclusive skin for the mythic shop.
