Patch 9.21 notes

By shio shoujo

Hi. Happy post-10-year! Did you get to catch the team's stream? We loved getting to answer your questions, play with some of you, and work on fixing some bugs that you outlined on the Boards. Thank you for interacting with us on that very special day.

We hope you enjoyed all the amazing things coming to League of Legends soon, including the preseason changes we've been alluding to for the past couple of patches. The bulk of our time is going into preparing for the Rise of the Elements gameplay update, but some notable work going live this patch includes follow-ups to the champions that received bigger changes in 9.20.

From all the past, present, and future writers of Patch Notes, thank you for making the last 10 years awesome. Here's to another 10 years of dumb jokes, obscure references, and "CTRL+F __, no results?" comments!

10/28/2019 URF is now live!

We’re bringing back URF as a one-time experiment to celebrate League’s 10-year anniversary. From now until November 8, jump into cannons, wreak havoc, and rapid fire it up on Summoner's Rift. As promised in the /dev article on Nexus, we've implemented some balance changes, similar to the way we did them in ARAM earlier this year, to keep the games snappier and less "solved."


Due to our extended testing window on PBE, we’ve been able to utilize a similar balancing approach to ARAM for URF, dialing in the approach specifically for the champions that really pop off. We’ve tried to make sure we adjusted champions in ways that do not hamper their classic URF patterns, while also not invalidating other champions as reasonable options. The changes below are the adjustments made from how each champ normally is on Summoner's Rift.
AATROX +25% damage dealt & -25% damage taken
AHRI -8% damage dealt
AKALI +15% damage dealt
ALISTAR +5% damage dealt & -10% damage taken

To keep URF fast, we want objectives that are powerful and threaten the end of games. That being said, older iterations of URF would end too quickly once these objectives were taken.

Additionally, turret plates are great for rewarding even small amounts of lane aggression in normal SR, but the tunings for that game mode often under-rewarded the risk it takes to hit turrets in URF, especially due to the speed at which enemies arrive back in lane. We’ve reduced the risk to get early plates, and we’ve dramatically increased the reward to make these a more interesting strategic option. Changes below are the system's values in this iteration of URF.
ELDER DRAGON SPAWN Elder Dragon will spawn at 9 minutes
ELDER DRAGON BUFF DURATION 120 seconds (base) & 180 seconds (empowered)
TURRET PLATE HEALTH 500-1500 based on the plate


We wanted to take a minimal change approach to runes, and tried to bring down only a few runes that really distorted the options last time URF was live. Similar to the system changes, the adjustments below are what they are now in this URF iteration.
TRANSCENDENCE 15% CDR at level 10 & 0.5 adaptive AP/0.3 adaptive AD for every 1% CDR overcap
GATHERING STORM Gains Adaptive Force every 6 minutes

10/23/2019 Waterwalking Bugfix


BUGFIX Champions will now properly activate Waterwalking at every part of the river, not just at the entrances

E base damage per spin decreased.

Nerfing Garen after his changes in 9.20. While this change might look large, we've kept the ratios the same, so it shouldn’t feel like a huge nerf.

E - Judgment

BASE DAMAGE PER SPIN 8/12/16/20/24 4/8/12/16/20
DAMAGE RATIO PER SPIN 0-8.2 (levels 1-18) (+32/34/36/38/40% attack damage) (unchanged)


Q damage increased; Rhaast's modified damage ratio increased; bonus damage to monsters decreased.

Both of Kayn's forms are underperforming right now, so we're adjusting his damage to give him a bit more oomph against champions, regardless of which form you choose.

Q - Reaping Slash

DAMAGE 60/80/100/120/140 75/95/115/135/155
RHAAST MODIFIED DAMAGE 0.5 total attack damage 0.55 total attack damage


Base stats rounded up. Q and E base damage increased.

Right now, Kog'Maw's E does not feel rewarding to cast, even when it lands successfully. Rather than decreasing the costs on his E's or other abilities' early ranks, we're upping their value so that Kog'Maw’s kit still has a risk vs reward element.

Base Stats

MANA 322.22 325
MANA REGEN 8.676 8.75

Q - Caustic Spittle

BASE DAMAGE 80/130/180/230/280 90/140/190/240/290

E - Void Ooze

BASE DAMAGE 60/105/150/195/240 75/120/165/210/255


E shield and damage increased later.

Lulu's transition into the mid-game could be better. We want Pix to offer more to fights and for players to make choices that are more worthwhile as Lulu scales.

E - Help, Pix!

SHIELD 80/115/150/185/220 80/120/160/200/240
DAMAGE 80/110/140/170/200 80/120/160/200/240


W cost flattened; damage increased. R root duration increased.

Maokai is underperforming across all levels of play and needs some help to keep up with his would-be lumberjacks.

Q - Bramble Smash

BUGFIX Maokai will no longer damage nearby targets if he's begun casting Q - Bramble Smash right before dying

W - Twisted Advance

COST 60/65/70/75/80 60 at all levels
DAMAGE 50/75/100/125/150 70/95/120/145/170

R - Nature's Grasp

ROOT DURATION 0.6-2.4 seconds (based on distance traveled) 0.8-2.6 seconds (based on distance traveled)

Master Yi

Phantom Hits now proc Double Strike and apply Double Strike stacks.

Passive - Double Strike

PHANTOM HIT BUGFIX Master Yi's Phantom Hits (from Guinsoo's Rageblade) will now properly proc Double Strike and apply Double Strike stacks


Base health growth decreased. Passive Grey Health from damage decreased.

When Pyke gets ahead, he takes advantage of the situation without any real risk, killing off folks left and right and becoming near-impossible to take down. He should still have trouble escaping after an assassination, even if he's doing very well. And if he makes a second pass at a kill, he shouldn't be at near full life.

Base Stats


Passive - Gift of the Drowned Ones

GREY HEALTH 30-81% (levels 1-18) of the damage he takes from enemy champions 25-50% (levels 1-18) of the damage he takes from enemy champions


W box duration decreased.

Shaco landed in a strong spot after 9.20, so we're doing some light touch-ups to address specific concerns about his lane presence and early jungle power.

W - Jack In The Box

BOX DURATION 60 seconds 40 seconds


Follow-up QoL change and passive bugfix for the adult woman.


RESOURCE BAR When her Passive - Power Chord is ready, Sona's resource bar will now change color based on her current active aura
PASSIVE BUGFIX Sona's abilities no longer fail to generate Passive - Power Chord stacks immediately after an empowered attack


Base stats rounded up. Q damage increased.

Viktor is a little weaker than we expected after the changes last patch. We're going light on the follow-up, since we know people are still getting accustomed to him. We're also including a bugfix that already happened in a mid-patch update in 9.20, since we weren't able to widely message it out at the time!

Base Stats

HEALTH 528.04 530
ARMOR 22.72 23

Q - Siphon Power

DAMAGE 50/65/80/95/110 60/75/90/105/120
BUGFIX Now properly buffs Viktor's shield when augmented

W - Gravity Field

SFX BUGFIX Gravity Field's SFX is no longer noticeably louder when using it against more than one enemy


Q damage ratio increased later. W bonus attack speed increased.

Warwick is falling behind the pack, especially when he maxes his Q before his W. We want him to still have the option of maxing out one over the other based on the situation, but they should both be on a more equal footing.

Q - Jaws of the Beast

DAMAGE RATIO 6/6.5/7/7.5/8% of the target's maximum health 6/7/8/9/10% of the target's maximum health

W - Blood Hunt

BONUS ATTACK SPEED 50/65/80/95/110% upon attacking a Blood Hunted target or an enemy unit below 50% of their maximum health 70/80/90/100/110% upon attacking a Blood Hunted target or an enemy unit below 50% of their maximum health
