Patch notes for League of Legends 4.2 are released, with the patch live now on North America and EUW.
Several changes to champions and the way matchmaking and ranked play is being done has been drastically changed. Players will now have a more "random" champion select order in draft modes. In addition, Xerath has received a rework and the "Perserverance" mastery has been nerfed in half, resulting in an across-the-board nerfs to the ever prevelant super tanks in the top lane.
LoL Client Updates
Repair System
With our improved repair system, any 3rd party modifications to the League of Legends client are at risk of being deleted if they cause the game to crash. Be careful!
- If you crash out of the game due to corrupt or missing data, the League of Legends patcher will automatically fix that bad data the next time you open it (so you don’t crash again)
- Soft Repair will not delete custom item sets while repairing your install
Ticker
The League of Legends ticker is an important communications tool for service status, so we’re upgrading it to deliver information better, faster and more clearly.
- Upgraded the notification box to handle more service status messages while also providing more information where necessary
Game invites
We’re taking a closer look at game invites and making some general quality of life buffs when it comes to setting up premade games.
- Updated the layout of the invite, start game, and quit buttons in the team invite lobbies for better clarity
Journal of Justice
Since the Journal of Justice has been out of publication for a while now, we're removing its link from the client. While the JoJ will be missed, we're exploring future storytelling methods for League of Legends.
- The lore tab (aka the feather) has been removed from the front of the LoL client
Leagues
Pick Order
We’re making pick order more consistent in ranked play. In most cases the skill gap between players on a team is not significant enough to justify granting the top player first pick. Basing pick order on a behind-the-scenes number isn’t a great experience - not to mention there are some odd side effects for duo queue players - so we’re taking a different approach.
- All players will now have an equal (random) chance of being first pick
- For players in a duo, if either player is chosen as first pick, the team captain will be assigned first pick and the other member of the duo will get whatever position the captain received from the randomizer
Vision System
Improving the in-game vision system is on our current hit-list, so you will see more updates to the vision system in the future.
- Fixed a bug where units in the same brush would sometimes be invisible even if they were in your line of sight
Additionally, we’ve made some progress in our long battle against the minimap visual bug demons. Completely solving the issue is a larger project we’re hoping to tackle, but these changes should significantly improve the situation.
- Fixed a number of minimap visual bugs. While this isn’t a complete fix, it should improve things overall.
General
We’re continually updating the visual fidelity of LoL across the board! In this patch, we’ve buffed up a few icons and spells.
Icon Updates
The following icons have been updated:
- Soraka’s ability icons
- Ashe’s ability icons
Particle Updates
The following summoner spells have been updated:
- Flash (particles and sound)
- Clairvoyance (particles and sound)
- Ghost (particles)
- Revive (particles)
Reworks

Xerath
Xerath is getting a complete overhaul of his kit along with new particle effects, ability icons, VOs and some new animations. Read below for the full details.
This rework isn’t driven by a concern for power levels. Instead, like a lot of our reworks, it’s focused on delivering a unique, cohesive champion theme. Xerath’s theme has always been the arcane sniper with huge damage potential. Give him time and the right target, and he can precisely pick off his victims. That said, with Xerath’s old kit, he had so much spell penetration and rapid-fire abilities that players would often just dump all of his damage on the nearest target. We believe his new kit delivers on a better champion fantasy.
General
Passive - Mana Surge
Every 10 seconds, your next basic attack restores between 30 and 195 mana. The amount it restores scales with your character level.
Q - Arcanopulse
W - Eye of Destruction
E - Shocking Orb
R - Rite of the Arcane

Skarner
We gave Crystal Slash a stacking attack speed buff and moved its slow over to Fracture, which in turn lost its heal mark mechanic. Crystalline Exoskeleton’s movement speed bonus now ramps up over 3 seconds instead of instantly and Impale will root the target during the windup animation.
We’re giving Skarner a moderate rework to bring him slashing and impaling into the modern day. Our goals are to improve his overall counterplay, make Fracture a more useful skill and bring him up to current jungle standards. These changes shouldn't have a dramatic effect on Skarner's overall play pattern but they should make his kit feel more cohesive overall.
General
Passive - Energize
Q - Crystal Slash
W - Crystalline Exoskeleton
E - Fracture
R - Impale
Champions

Ashe
We reduced Hawkshot’s cooldown at later levels and changed its bonus gold to 3 at all ranks.
Basically, we wanted Hawkshot to feel more valuable at rank 1.
E - Hawkshot

Dr. Mundo
Mundo’s cleavers got skinnier.
Designers keep watch over Mundo with skinny cleaver change. Now Mundo get no corporate bonus for bad cleaver. This separate good Mundo from great Mundo.
Q - Infected Cleaver

Evelynn
The closer Evelynn is to her target, the faster her Hate Spike projectile travels.
We still like the notion behind our last Hate Spike change, but we’re not really happy with how it feels in game. Adjusting the ability’s missile speed still rewards enemies for keeping their distance, but also rewards Evelynn for getting up close and personal.
Q - Hate Spike

Kayle
We lowered Reckoning’s AP ratio while raising the AP ratio of Divine Blessing’s heal. We also added an AP ratio to Divine Blessing’s movement speed bonus and removed Intervention’s mana cost.
Once she gets ahead, Kayle's burst damage can be overwhelming to play against. While we're taking away some of Kayle's up-front burst, the utility scaling on Divine Blessing should help her and her team get INTO (and out of) THE FRAY.
Q - Reckoning
W - Divine Blessing
R - Intervention

Riven
We lowered Riven’s base health regen and increased the power of Valor’s shield.
We’re reinforcing one of Riven’s core philosophies: she's a champion who should rely on mitigating or avoiding damage to be successful. Enemies who harass Riven should feel rewarded for hitting her when her defenses are down, while Riven players can feel better about using her buffed shield to prevent that damage in the first place.
General
E - Valor

Rumble
Flamespitter looks… okay.
Rumble now spits real flame instead of meatballs.
Q - Flamespitter

Thresh
Thresh’s very long range basic attack is a powerful threat in lane, so this change introduces a little more vulnerability to his kit.
General

Yasuo
It now takes more movement to generate flow and Sweeping Blade gives less flow when Yasuo dashes. We also reduced Last Breath’s cast range.
We made some general quality of life changes to Yasuo in patch 4.1 , but as players begin to master him, we’ve seen how strong he is when played to maximum effectiveness. We looked at areas where we could reduce some of that power without messing with his core playstyle. We were also unhappy with how Yasuo was using Last Breath to engage in fights by teleporting from thousands (and thousands) of miles away.
Passive - Way of the Wanderer
Q - Steel Tempest
E - Sweeping Blade
R - Last Breath

Ziggs
Hexplosive Minefield will deal less damage to minions as they hit successive mines. Short Fuse’s base damage and AP ratio were both reduced at lower levels.
Our changes to Ziggs in patch 3.13 turned him into monster when it comes to pushing and counterpushing. While we like the philosophy behind the change, Hexplosive Minefield is a little too good as a wave clear tool, letting Ziggs play passively without any repercussions. The Short Fuse change has a bunch of numbers, but the TL;DR is that it’s just a small nerf to Zigg’s early game harass.
Passive - Short Fuse
E - Hexplosive Minefield
Minor Changes and Bug Fixes
In our ongoing effort to create a more consistent League of Legends viewing experience, we’re standardizing certain elements of our user interface. Players using the old legacy floating combat text prior to this change will be assimilated into the collective player experience. Beep boop.
- Removed legacy floating combat text
- Added ticks to Vilemaw's health bar
- Fixed a bug that stopped the HUD from scaling while the game was paused

Akali
R - Shadow Dance

Elise

Masteries

Perseverance
Perseverance as a mastery is incredibly powerful in comparison to other equivalent masteries - particularly once you get your first big HP item - so we're bringing it more in line.
Summoner’s Rift
The changes affect Summoner’s Rift Only

Turrets
Back in Patch 4.1 we made this change to directly counter fast push strategies in competitive play. Reducing the timing to 8 minutes from permanent is more in line with what we wanted to accomplish, so we did just that.
Top and mid lane outer turrets
Twisted Treeline
These changes affect Twisted Treeline only

Kha’Zix
Same changes that exist on the Crystal Scar
Q - Taste Their Fear
Evolved Enlarged Claws
