Hi friends. It’s just about that time to wake up, ‘cause September’s coming to an end.

This patch is on the lighter side, with most changes concentrated on tuning champion scaling as games progress. Big ticket items include a helping hand to a certain blue mage by giving him more damage to play with, along with tempering down Karthus who’s been a nightmare in the bot lane. Apart from champion changes, Worlds 2020 Clash is on its way to you! It's time to be the hero and to kiss away the pain. And to win a cool trophy.

On a clerical note, upon logging in this patch, you’ll be presented with the new Code of Conduct. This agreement helps us define the behaviors we expect of you as a player.

So get on the rift and that future boom boom boom. You gotta get that.

Take this portal if you're looking for TFT's patch notes!

Patch Highlights

Storm Dragon Aurelion Sol, Eternal Dragon Brand, Obsidian Dragon Sett, Fae Dragon Ashe, Storm Dragon Lee Sin, and Obsidian Dragon Sett Prestige Edition will be available on October 1st, 2020.



R self-healing increased later.

Aatrox wants to step into his full potential as the unkillable DPS monster, so we’re helping him harness his darkin power by curbing some of his mid- to late-game falloff. Hopefully now this warrior demon won’t fall flat in late game teamfights.

R - World Ender

SELF-HEALING 50/60/70% 50/75/100%


Q base damage increased; cost decreased.

We’re giving Braum a little more agency in solo queue with some extra damage and lower mana costs.

Q - Winter's Bite

BASE DAMAGE 60/110/160/210/260 75/125/175/225/275
COST 55/60/65/70/75 mana 45/50/55/60/65 mana


Passive tentacle spawn cooldown decreased.

Illaoi has been flailing around top lane, so we’re giving her tentacles more oomph, especially post laning phase. We’re also smoothing out her passive scaling so that she gets some benefit every level instead of every two.

Passive - Prophet of an Elder God

TENTACLE SPAWN COOLDOWN 20-12 seconds (scales every 2 levels) 20-7.25 seconds (scales every level)


Base armor decreased.

We're continuing to tweak Karthus to get him into a comfortable place since he’s been a bit overwhelming across the map, especially in bot lane. Aiming to bring down his defenses against ADCs.

Base Stats

ARMOR 20.88 18


Q shield decreased early.

Kassadin players in Skilled/Elite are too often able to stonewall lanes and scale with their early defensive tools. Many have started maxing E first, so we're pushing Kassadin to have to invest more for a safer laning phase.

Q - Null Sphere

SHIELD 60/85/110/135/160 40/70/100/130/160


Dagger retrieval damage ratio decreased.

Katarina has risen in the ranks in Skilled and Elite games as a swift assassin who can secure snowball advantages with early roams, so we’re targeting her AD ratios to lower some of her early threat.

Passive - Voracity

DAGGER RETRIEVAL DAMAGE RATIO 1.0 bonus attack damage 0.75 bonus attack damage


Base magic resistance decreased.

Kled has been a strong force in both mid and top lane at all levels of play, so we want to open up more avenues to knock this yordle off his high horse lizard.

Base Stats



W bonus attack speed decreased.

Lulu has seen wild growth in the bot lane by helping carries out a pinch too much. Since she’s both a strong offensive and defensive support, we're toning down her combative scaling on Whimsy in the late game.

W - Whimsy

BONUS ATTACK SPEED 25/30/35/40/45% 20/23.75/27.5/31.25/35%


Q base damage decreased later.

We’re cutting down some of Maokai’s brawling power to give his top lane peers some space to come out of the woods.

Q - Bramble Smash

BASE DAMAGE 70/115/160/205/250 70/110/150/190/230


Base armor decreased.

Nunu's skirmishing power is a little too strong when coupled with his top-tier gank presence and objective control. Weakening some of that strength so he rolls over junglers a little less.

Base Stats

ARMOR 32 29


Q base damage increased.

Since he’s recently escaped from his Worlds rune prison, we're ready to overload Ryze in preparation for the offseason.

Q - Overload

BASE DAMAGE 65/90/115/140/165 75/100/125/150/175


Q damage ratio to monsters increased.

Sion could use a little help in the jungle, so we’re charging up his Q. A fun bonus: now he can slay baby Raptors more efficiently with his Q+W combo.

Q - Decimating Smash

DAMAGE RATIO TO MONSTERS 1.0 attack damage 1.5 attack damage


Passive damage to monsters increased early. W modified damage now affects both minions and monsters.

The jungle could juggle a few more juggernauts, and Urgot has what it takes to be a viable pick. We’re beefing up this beefy man’s damage against monsters.

Passive - Echoing Flames

DAMAGE TO MONSTERS 60-360 100-360

W - Purge

MODIFIED DAMAGE 50 to minions 50 to minions and monsters


E base damage increased. R cooldown decreased.

After a long time spreading corruption at the highest tiers of play, Varus has fallen and once again has room for buffs.

E - Hail of Arrows

BASE DAMAGE 50/90/130/170/210 60/100/140/180/220

R - Chain of Corruption

COOLDOWN 130/100/70 seconds 120/90/60 seconds


Relentless Hunter

Relentless Hunter is massively outperforming other runes, especially in Skilled mid lanes. We’re bringing down its reliability and reducing some of its base power.
OUT-OF-COMBAT MOVEMENT BONUS 10 movement speed (+9 movement speed per Bounty Hunter stack) (up to 55 at 5 stacks) 5 movement speed (+8 movement speed per Bounty Hunter stack) (up to 45 at 5 stacks)
