Patch 15.21
Data Dragon 15.21.1 · 10/21/2025 · Official notes












TL;DR
Patch 25.21 is bee-autiful! 🐝
It's time for Patch 25.21! We hope your Pick 'Ems are going well in the Swiss stage and if not then maybe the Crystal Ball picks will save you. On the balance front we're delivering some important systemic changes to early lane aggression with nerfs to Doran's Shield and Second Wind, plus better incentives for aggressive play with Doran's Ring. We're also bringing back Gwen to her pre-update state earlier this year, bringing back Graves's magic resist through Grit stacks, nerfing Dr. Mundo's late game burst, and swinging at the biggest balance outliers for regular at-home play. This patch, we've got the Act 2 Pass that has double the currencies in celebration of Worlds being back in full swing, so make sure to complete that to get double BE, OE, and ME. We've also got the brand new ARAM Mayhem, sporting an entirely new experience around ARAM but filled with augments! Create the snowball build of your dreams, or your enemies' nightmares. We've also got an update to the Practice Tool that will allow you to try out champions before you buy them, some updates to some min spec changes we made earlier this year, and of course, some new goodies in the Sanctum and Mythic Shop!

We're pretty happy with Bard's current balance state but would like to open up some more options for him, namely in building AP items like Shurelya's, making him better at supporting his team when playing AP-heavy.

W - Caretaker's Shrine
Minimum Heal: 25 / 50 / 75 / 100 / 125 (+ 30% AP) → 25 / 50 / 75 / 100 / 125(+ 40% AP)

W - Caretaker's Shrine
Maximum Heal: 50 / 87.5 / 125 / 162.5 / 200 (+ 60% AP) → 50 / 87.5 / 125 / 162.5 / 200(+ 70% AP)

W - Caretaker's Shrine
Movement Speed: 20 / 22.5 / 25 / 27.5 / 30 (+ 5% per 100 AP) → 20 / 22.5 / 25 / 27.5 / 30(+ 6% per 100 AP)

BUFFEDDianaDiana's last buff to her jungle clears overshot a bit, so we're walking it back slightly to keep her in line.
Passive - Moonsliver Blade
Monster Damage: 300% → 280%

Dr. Mundo is a scaling juggernaut who has to wade through a fairly weak early game in order to scale into the ability to go wherever he pleases. And we're happy he's able to go where he pleases, but he's bursting whomever he pleases a bit too easily. We're looking for some power neutral adjustments that take away some late-game burst and give back late-game durability in its stead.

E - Blunt Force Trauma
Minimum Active Damage: 5 / 15 / 25 / 35 / 45 (+ 7% Bonus HP) → 5 / 15 / 25 / 35 / 45 (+ 5% Bonus HP)

BUFFEDEzrealEzreal has been a low performer lately especially at lower ranks.
Ezreal has been a low performer lately especially at lower ranks. We're looking to add a little bit of general power to help him keep up as games go late.

CHANGEDGravesWe'd like to nudge Graves back toward having a strong sustained fight pattern and that means letting him rely on Grit and playing to stack it up.
We'd like to nudge Graves back toward having a strong sustained fight pattern and that means letting him rely on Grit and playing to stack it up. As he's getting this MR from Quickdraw, he can once again have the base magic resistance of a ranged champion. So, if you can catch Graves before he's able to stack up, he's more burstable than before, but if he's able to play the fight out the way he wants, he'll grow to be the sustained monster we all know and hate love.

E - Quickdraw
Now grants 50% of armor as bonus Magic Resistance.

E - Quickdraw
Magic Resistance per stack: 2 / 3.5 / 5 / 6.5 / 8

E - Quickdraw
Max Magic Resistance: 16 / 28 / 40 / 52 / 64

NERFEDGwenBack in 25.06 we sought to give Gwen more power over her laning phase while still being that scaling AP skirmisher.
Back in 25.06 we sought to give Gwen more power over her laning phase while still being that scaling AP skirmisher. However, those changes have left her in a less popular state that has alienated Gwen players from the version of her that they enjoyed. So we're going back to almost the exact same champion from 25.05, with two differences: Her armor growth is a little lower, and her jungle levers are weaker. These two changes weren't reverted because she was a little too strong in top and significantly too strong in the jungle back before the changes. Enjoy your Gwensday tomorrow!

Passive - A Thousand Cuts
AP Ratio: 0.55% per 100 AP → 0.6% per 100 AP

CHANGEDKalistaKalista has been underperforming for quite a while now and we'd like to carve out some mid-game strength for her.
Kalista has been underperforming for quite a while now and we'd like to carve out some mid-game strength for her. We're hoping to achieve that by increasing her attack damage growth, which directly feeds into her attacks as well as her Q and E damage.

NERFEDKog'MawKog'Maw is one of the winningest bot laners in the game and has also lost his old identity as a scaler.
Kog'Maw is one of the winningest bot laners in the game and has also lost his old identity as a scaler. We're delivering a targeted nerf toward his early trading in order to re-balance him and retain some of that scaling potential.

Q - Caustic Spittle
Passive Attack Speed: 10 / 15 / 20 /25 / 30% → 5 / 10 / 15 / 20 / 25%

CHANGEDMorganaMorgana has taken off as a highly powerful mid laner across all ranks of play.
Morgana has taken off as a highly powerful mid laner across all ranks of play. We're super happy that she's found a new audience here but she's also meaningfully overpowered. In order to open up some more weaknesses, we're looking to bring down her guaranteed durability, making her rely more on Black Shield and Soul Siphon.

NERFEDQiyanaQiyana has been one of the clear winners from the recent changes to Profane Hydra and Axiom Arc.
Qiyana has been one of the clear winners from the recent changes to Profane Hydra and Axiom Arc. She's been taking over in both mid lane and jungle especially in elite play. We're hitting her with some nerfs that'll take her down a notch in both roles.

Q - Elemental Wrath / Edge of Ixtal
Damage: 70 / 100 / 130 / 160 / 190 (+ 90% Bonus AD) → 70 / 100 / 130 / 160 / 190 (+ 85% Bonus AD)

CHANGEDQuinnQuinn has been one of the winningest top laners for a while now and with us nerfing both Doran's Shield and Second Wind this patch, we're confident that Quinn is due for some nerfs of her own lest she completely overtake top lane.
Quinn has been one of the winningest top laners for a while now and with us nerfing both Doran's Shield and Second Wind this patch, we're confident that Quinn is due for some nerfs of her own lest she completely overtake top lane. We hope that these nerfs will open up her build options away from simply high AD lethality burst, allowing her the space to play out a more sustained auto-attacking pattern.

Q - Blinding Assault
Damage: 65 / 100 / 135 / 170 / 205 (+ 80 / 90 / 100 / 110 / 120% Bonus AD) → 65 / 100 / 135 / 170 / 205 (+ 80 / 85 / 90 / 95 / 100% Bonus AD)

R - Skystrike
Damage: 70% Total AD → 60 / 90 / 120(+ 35% Bonus AD)

Yone's been a low performer for quite a while now, and the upcoming changes to Doran's Shield and Second Wind will likely leave him in a pretty sad state. We'd like to pre-emptively give him some early game power to make up for it.

We're here to buff Yunara today. As she's still relatively new, over two thirds of her games are played by inexperienced players, substantially dragging down her win rate. But even after accounting for that fact, she's still weaker than the average bot laner. We want to achieve two goals here: First, we want to improve the value of ability ranks in W so that players who invest in spell damage are rewarded for their skill points. Second, we want to make her more consistently mobile, bringing up Kanmei's Steps average movement speed so that players don't have to hold it just to juke a key skillshot and instead can take more proactive and aggressive fights.

W - Arc of Judgment
Initial Damage: 5 / 30 / 55 / 80 / 105 (+ 85% Total AD) → 55 / 95 / 135 / 175 / 215 (+ 85% Bonus AD)

W - Arc of Judgment
Damage per second: 5 / 20 / 35 / 50 / 65 (+ 40% Total AD) → 33 / 57 / 81 / 105 / 129 (+ 51% Bonus AD)

W - Arc of Ruin (Transcendent State)
Damage: 50 / 200 / 350 (+ 175% Total AD) → 175 / 350 / 525 (+ 150% Bonus AD)

E - Kanmei's Steps
Movement Speed: 30 / 35 / 40 / 45 / 50% decaying over 1.5 seconds → 30 / 35 / 40 / 45 / 50% decaying after 1.5 seconds

E - Kanmei's Steps
Movement Speed toward Enemies: 45 / 52.5 / 60 / 67.5 / 75% decaying over 1.5 seconds → 45 / 52.5 / 60 / 67.5 / 75% decaying after 1.5 seconds

E - Kanmei's Steps
Cooldown: 7.5 → 9

E - Kanmei's Steps
Step Right: Fixed a bug where Yunara could retain the enhanced movement speed without facing any enemy champions

NERFEDCatalyst of AeonsCatalyst needs to be competitive with Lost Chapter in giving tankier AP champions enough mana to play out their laning phases.
Catalyst needs to be competitive with Lost Chapter in giving tankier AP champions enough mana to play out their laning phases. It does not, however, need to invalidate burst damage so strongly. So we're delivering a small health nerf until it's turned into Rod of Ages.

We're moving Doran's Blade back to its 14.1 version with omnivamp because the item is meant to serve more than just attackers, but instead a wide range of AD champions, such as those who rely on abilities do deal their damage.

CHANGEDDoran's RingThe current tuning of some starter items and Second Wind can make it feel pointless to attempt to harass during lane phase, resulting in stale gameplay especially in mid lane where players don't play for kills often enough.
The current tuning of some starter items and Second Wind can make it feel pointless to attempt to harass during lane phase, resulting in stale gameplay especially in mid lane where players don't play for kills often enough. With these changes, we're attempting to nudge back towards poke being more valuable in the lane phase.
