Champion Changes
PBE LoL Patch 12.23: Zeri Mini Rework

To start off this row of champions changes we start off with the Spark of Zaun.
Despite having a dominant season for many patches in competitive. after her nerfs in patch 12.16 Zeri has been one of the worst performing champions in the game, even going to depths of 42% Win Rate (The worst WR of any champion)
In a effort to bring her back to the game, the balance team are making changes to give her a spark (Had to do it) back in the game.

Amidst Preseason and TFT Set 8 on PBE, it's a perfect time for me to slip in some SMALL Zeri changes while no one is looking. These are coming to PBE today! More details in thread pic.twitter.com/dMKkd7Ufbg

These changes are big, the nerf to W and change towards AD may stop her toxic AP build, the Q range being less makes her more weak at longer ranges, something that should be from the beginning taking into account the mobility give by E. These buffs are going to mark for sure the return of Zeri, whether she be broken or underwhelming needs to be seen when changes are live.
Dr. Mundo Balance Changes in PBE LoL Patch 12.23

Dr. Mundo players are receiving some love, but mostly for the jungle role. These changes were teased a few days ago by Riot Pehrek, aimed towards improving his jungle especially the damage on his Blueforce Trauma (E), and increasing his AD scaling to max health, something pretty good considering the new FOTM item Heartsteel.
But don’t get you hopes too high, the loss of extra AD from Maximum Dosage (R) may hurt his dueling potential, something that he has struggled specially against Fiora in the top lane. Although the new healing numbers look great for teamfighting.
Base Stats
AD per Level: 3.5 –> 3
Base Magic Resist: 32 –> 29
Magic Resist per Level: 2.050 –> 2.3
Goes Where he Pleases (P)
Cannister Current Health Loss: 7% –> 3%
Cannister Max Health Heal –> 8% –> 4%
Max Health Regen per 5s –> 0.8-1/6% (linear progression) –> 0.4-2.5 (non-linear progression equal at level 11)
Infected Bonesaw (Q)
Health Cost: 50 –> 60
Heart Zapper (W)
Health Cost: 5% current Health –> 8% current Health
Gray Health Heal (No Hit): 0% –> 50%
Damage Stored as Gray Health: 25/30/35/40/45% –> 80-95% based on level in the first 0.75s, then 25% thereafter
Duration: 4s –> 3s
Blunt Force Trauma (E)
Passive Bonus AD: 15/20/25/30/35 + 25/30/35/40/45 based on missing health –> 2.5/3/3.5/4/4.5% max Health
[Removed] Instantly push small jungle monsters
Monster Damage: 200% –> 250%
Maximum Dosage (R)
[Removed] Bonus AD
Missing Health as Max Health: 8/11.5/15% –> 15/20/25%
[Added] At Rank 3, both healing effects (R regen and base health gain) are increased by an additional 5% per nearby champion
Hey, y'all! @Damascus_Glenn made some new Dr. Mundo changes which should be on the PBE soon.
We are primarily changing how his W works and have also tweaked his other abilities. Aiming to make him more viable in the jungle! 🪚🩹 pic.twitter.com/UBqIB66CEk— Pehrek (@RiotPehrek) November 15, 2022
Quality Of Life changes for Kassadin
After the addition of Rod of Age in patch 12.22 you probably thought that Kassadin would have a great time, but thats far from the truth. The Void Walker winrate is below 50% despite having a pick rate of 7%, so to make this antimage more viable they have stored a few changes for the next patch to make him feel better.
Null Sphere (Q)
Shield granted on spell cast rather than when the missile leaves his hand (small buff to make parry more reliable)
+20 Shield per Rank: 60/90/120/150/180 – 80/110/140/170/200
– 10% Shield AP Rato: 40% to 30%
Force Pulse (E):
Spell no longer locked out and requiring nearby spell casts
Nearby spell casts reduce the Cooldown by 1 second
Cooldown: 5 to 21/19/17/15/13
Working with @MaxwellPerlman on some nice QOL Kassadin changes I am pretty excited for. We are planning for 12.23 but things can always change. pic.twitter.com/S0zLFs4vqU

Abyssal Dive (W)

Devour (R)
Shield now decays by 200 per second instead of lasting 2.5 seconds

New ARAM changes look neat for the gameplay, although don’t know how they will affect the ARAM Clash tournament dated for December 7th. These changes are going to give a breath of fresh air for the second most popular game mode in LoL, and hopefully make it more exciting for Summoner Rift boomers.
Youtuber Vandiril already do some testing in the new ARAM map and they seem pretty interesting.
Last note: Teased Mid Scope Update for Jax and Rell
After a lot of the hype for Rell, back when she was announced, the Iron Maiden hasn’t actually met much of the expectation, and even feeling very clunky to play.
Don’t misunderstand me, by no means she’s a bad champion, at the contrary, in higher elo she sees much success, but, her popularity among average fanbase is very low, so these changes are a promising look for the Iron Maiden.
Where’s Jax? Well, his changes seem to be smaller, just focused on the feeling of his ult.
We now have midscope updates in flight for Jax and Rell! I'm helping get Jax out the door w/@ExasperatedDan and @RiotRaptorr is working on Rell! No release dates to share yet. Will keep you updated.
Also, we haven't forgotten about Neeko. She'll be ready early next year. pic.twitter.com/LDK6XBlKrn
