LoL 25.04 (15.4) Patch Notes

LoL 25.S1.4 (15.4) Patch Notes - All Changes — Riot Games

A lot of drastic changes were unveiled prior to 2025 as League of Legends is steadily moving towards an even more dynamic and exciting MOBA experience. Given its legacy and player base, LoL is no stranger to feedback from the community, either positive or negative, however, it is interesting to see how the devs will navigate all of the updates to both Splits, game balancing and more.

Whether you are busy venting your frustration over the diminishing skin quality or the removal of Hextech Chests, keeping up with balancing decisions will also be important if you wish to climb up the ranked ladder so here are all of the changes listed in 25.04.

LoL Patch Notes

Patch Naming

We initially went to 25.S1.1 with the hopes of tying patches more closely to seasons, and after a couple of patches we've realized it's not the easiest thing to communicate and wasn't really hitting the mark the way we hoped.

So this patch is 25.04, with the last patch this year being 25.24. Then come January 2026 it'll be 26.1, you get the idea. This will also tie the patch numbering to how we talk about our other events like Worlds much closer each year.

Honor Revamp

As of this patch, the Honor system has been revamped to better reflect how players interact with one another. Instead of steadily progressing over a Season (unless you're penalized), your Honor now updates regularly based on your recent behavior. Our goal with these changes was to make Honor about how you show up and the positive impact you have on your teammates, not just how many games you've played. As always, we want this system to create a safer and more positive environment for everyone in the community and we believe these changes will help get us there.

Now that Honor is a more accurate evaluation of behavior, we're tying it to communication privileges and other rewards. Honor 3 now represents neutral players who aren't being disruptive or positive. All the baseline features to play and communicate with your team are available at this level. Higher levels of Honor are reserved for players who are consistently positive, respectful, and collaborative. These players are rewarded Battle Pass XP drops and benefits like visible Honor levels. At Honor 5 you'll gain access to ally-targeted pings to call for things like Dearest Karthus's ultimate. Meanwhile, Honor levels 1 and 2 indicate an active penalty on your account due to recent disruptive behavior and, as a result, access to rewards and some chat usability will be restricted.

For even more details about the system, check out the Honor FAQ here! These updates will go live on February 20th 21:00 UTC, shortly after the patch goes live.

Honor Levels: Amount of games played without penalties ⇒ Dynamic evaluation based on recent positive behavior.
Rewards & Entitlements: Based on your current Honor; more info available at Honor FAQ.
Honor Checkpoints & Seasonal Resets: Gone!
Demotion Warnings: Will notify you when your Honor is sliding to the previous level.
Honor Penalties: Game-based; The amount of matches you must play to lift the penalty is viewable in your profile the same way Ranked Restrictions are today.
Honor Tokens: Any remaining Honor 5 tokens in loot will be converted into 1050 Orange Essence at the start of patch 25.06.
Progression: Honor Orbs and Capsules have been replaced with Battle Pass XP drops.
Rewards: After 25.04, the first time you reach Honor 5 you will be permanently awarded the Three Honors Malzahar, Shen, and Akshan skins, alongside Grey Warwick and Medieval Twitch and their chromas.

Systems

Atakhan

In this patch we've adjusted Atakhan's Form Spawn Rules to better reflect how bloody a game feels with what form Atakhan takes on. This also includes accounting for differences between what a bloody game looks like in Solo Q vs Professional Matches.

Early Lane Trading: Pro play features more aggressive early lane trading, and champions simply have less health early anyways so smaller amounts of damage represent greater bloodiness. Therefore we are increasing the impact of early game PvP damage on Bloodiness Score to a greater degree.

Early PvP generates double the points, decreasing down to the normal amount over 14 minutes

Diminishing Kill Score: Functionally, so long as “enough” kills happen, the game feels bloody and lively. This means that the first few kills are more significant than subsequent ones.

The first few kills per game grant significantly more points, diminishing with each subsequent kill.
Tower Dives in particular are extremely high tension moments, and therefore tower dive kills grant multiplicatively more points.
Threshold Recalibration: Because these adjustments change point values significantly, we are adjusting the Voracious vs Ruinous threshold to try to better match these new expected values.

2025 Clash Schedule

Clash 2025 is just around the corner so get your 5 stacks and clear these dates for your shot at Clash supremacy! As mentioned in the last dev update, we're reducing the amount of Clash tournaments this year from 12 to 6 total. But we are going to be experimenting with some new tournament formats like ARURF Clash and bringing back player favorites like the ARAM Cup. So get your teams together and we'll see you on the Rift (or Howling Abyss)!

ARAM

Hello ARAMers!

We have a light patch for 25.04, with a focus on Teemo. Trap-based champions have historically been difficult to balance due to ARAM's unique vision system. This time, we're giving Teemo players back more opportunities to plant shrooms while reducing their overall impact. Our goal is to maintain his champion fantasy while keeping an eye on frustration levels.

On the tank front, several tank items have been nerfed in Summoner's Rift this patch. We'll be monitoring tanks' performance in ARAM to determine whether individual adjustments are necessary. We're also working on a Sett nerf for the next patch, so stay tuned! And as always, GLHF!

Teemo

Death Timers

Now that there's a hard cap on how long Swiftplay games can go, we're pulling down on late-game respawn timers so that players can more readily fight for their (Nexus's) life.

Death Timer Multiplier (minutes 10-35): 100-133% ⇒ 100-112%

Champions

Now that Yorick has a sudden death cutoff that covers up his weak endgame power COMBINED with the fact that the sudden death mechanic favors his specialty of dealing structure damage his power levels are off the charts, so we're here to bring Yorick back down to Earth Runeterra.

AD Growth: 5 ⇒ 4.3
R Maiden Mark Damage: 2/2.5/3% max health ⇒ 1.5/1.75/2% max health
