Patch 10.15 notes

The blossoming of spirits, dreams, and a frolicking fawn...

Hi, we’re so happy you’re here!

This patch, we welcome the arrival of the Spirit Blossom Festival, first with the entrance of Lillia, our brave guardian from Ionia, and then the return of Nexus Blitz (oh yes, it’s back!), all set in an ethereal realm of wondrous magic and bloom.

Then, greetings to a refreshed Swain! We’re hoping these spicy changes (higher cast cadence and huge bump up in range) will fire up his power both as a mid laner and support. We’ve also taken another pass at Aphelios to tone down his dominance and fine-tune the synergy of his Flamethrower with Runaan’s.

For the rest of our changelist, we’ve made some Pro-targeted adjustments to champions like Shen and Lee Sin to encourage more diversity in their lanes, while also nudging old friends like Caitlin and Gragas back onto the scene.

In addition, we’re giving some folks a couple visual changes and audio fixes, focusing on champions with effects that have become outdated in comparison to their newer peers.

Oh, and one more thing— we’ve brought more flex into Flex queue by lifting rank restrictions! We know, we’re just flexing at this point.

Now, go forth. It��s your time to blossom.

Patch Highlights

Spirit Blossom Thresh, Spirit Blossom Vayne, Spirit Blossom Yasuo, Spirit Blossom Lillia, Spirit Blossom Teemo, and Spirit Blossom Teemo Prestige Edition will be available on July 22nd, 2020.

More Flexible (Ranked) Flex

With the introduction of Clash and its unrestricted rank system for full teams of 5, we’ve decided to apply the same approach to Ranked Flex queues, allowing players to get in ranked games with their Bronze buddies, Challenger chums, or whoever!

Similar to Clash, the system will use a weighted average that leans more towards higher skill players, so be warned before attempting to drag your Bronze friends through Diamond-level games. Have fun!




The Bashful Bloom

Lillia prances into action in patch 10.15!
High-res versions of Lillia's splashes are available on League Displays!


Q sentry activation radius decreased; sentry activation time increased. Q Runaan’s bolt pass-through effect removed; Infernum critical AoE splash missile count decreased; Infernum Runaan’s AoE splash missile count decreased; Infernum critical Runaan’s AoE splash missile count reduced; Infernum Runaan’s AoE splash missiles size reduced.

Lowering Crescendum turret's attack range so it provides less zone control, and slowing down its target acquisition speed so opponents can reactively play around it. The rest of the changes are aimed towards weakening Infernum’s synergy with Runaan’s Hurricane.


BUGFIX Aphelios' Lunar Sentries now properly proc Manaflow Band

Q - Crescendum, the Chakram

SENTRY ACTIVATION TIME 0.25 seconds to attack target in range 0.35 seconds to attack target in range

Q - Infernum, the Flamethrower

removedRUNAAN’S BOLT PASSTHROUGH Runaan’s Hurricane bolts no longer deal damage to all enemies they pass through (splash missiles and normal Infernum firebolts still do)
CRITICAL AOE SPLASH MISSILES COUNT 8 splash missiles 6 splash missiles
RUNAAN’S SPLASH MISSILES COUNT 4 splash missiles 3 splash missiles
CRITICAL RUNAAN’S SPLASH MISSILES COUNT 8 splash missiles 5 splash missiles
updatedRUNAAN’S AOE SPLASH MISSILES SIZE Hurricane splash missile AoE lengths are now reduced by ~100 range

R - Moonlight Vigil

BUGFIX No longer deals damage without going on cooldown if Aphelios is killed during the ability's cast


Base attack damage and movement speed increased.

Caitlyn has been out of the meta in Pro play for a very long time, and we expect her to be a reasonable fit with and against certain meta compositions. These changes should help bring her back as one of the premier early game marksmen.

Base Stats



W healing from minions reduced.

Tank Fiddle has been spooking opponents top lane, outperforming other builds (specifically AP Fiddle), and frustrating players who run into it. We don’t want to terrify the tank off the scarecrow, but with Jungle Fiddle being in a good spot, we’re hoping these changes will encourage players to indulge in the bounty of Fiddle as a mage, first and foremost.

W - Bountiful Harvest

HEALING Reduced to 25% against minions Reduced to 15% against minions


W damage ratio increased. R damage ratio increased.

Aiming to rouse this liquor connoisseur to step into his role as an AP mage who can both engage fights and burst down enemies, so we’re sharpening his late-game damage.

W - Drunken Rage

DAMAGE RATIO 0.5 ability power 0.6 ability power

R - Explosive Cask

DAMAGE RATIO 0.7 ability power 0.8 ability power


Passive bonus attack speed per stack increased later.

Our bladed dancer has been falling off in extended games at all levels of play, especially in Average MMR. Cautiously strengthening her scaling and dueling potential to help bridge the gap between laning phase to mid game.

Passive - Ionian Fervor

BONUS ATTACK SPEED PER STACK 8/10/12% (40/50/60% at levels 1/7/13) 8/12/16% (40/60/80% at levels 1/7/13)

Lee Sin

W cooldown increased.

We can’t turn a blind eye to the fact that Lee has been a consistent threat in Elite and Pro play, so we’re increasing the cooldown on one of Lee's more reliable spells to curb his mobility and sustain throughout the game.

W - Safeguard

COOLDOWN 12 seconds 14 seconds


Base armor decreased.

Slightly taming the fire on this forger so that his enemies have more opportunities to trade back.

Base Stats

ARMOR 36 33


Passive cooldown decreased later and now scales per level, capping at level 18.

We’re making Rakan’s progression across the course of a game feel smoother. This is a quality-of-life change that is also a very minor buff for this saucy showman.

Passive - Fey Feathers

COOLDOWN 40-16 seconds (levels 1-17) (reduced by 3 every 2 levels, capping at level 17) 40-14.5 seconds (levels 1-18) (reduced by 1.5 every level, capping at level 18)


Passive shield value increased.

We’re bringing some power into Shen’s shield to let him scrap with meta peers more effectively, while giving him more breathing room in lane. We’re hoping this will stir up some diversity in the top lane and overall team compositions with the introduction of a second tank to the meta.

Passive - Ki Barrier

SHIELD VALUE 50-101 (levels 1-18) 70-121 (levels 1-18) (bonus health ratio unchanged)


Q damage ratio and bonus damage ratio now scales with target’s maximum health; buff duration increased, cost increased and now flat.

We’re increasing the scorpion’s damage so he’s more equipped to slash through front line targets when itemizing as a bruiser (and a stinger, of course). As another flourish, we’re also making a quality-of-life change to his E.

Q - Crystal Slash

DAMAGE RATIO 33/36/39/42/45% total attack damage 15% total attack damage (+1/1.5/2/2.5/3% of target's maximum health)
BONUS DAMAGE RATIO 33/36/39/42/45% total attack damage (+0.3 ability power) 15% total attack damage (+1/1.5/2/2.5/3%of target’s maximum health) (+0.3 ability power)
BUFF DURATION 4 seconds 5 seconds
COST 10/11/12/13/14 mana 15 mana

E - Fracture

removedKEEP IT MOVING Missile no longer loses travel speed after hitting an enemy


Base movement speed decreased. Passive cooldown decreased and now scales with cooldown reduction; no longer restores mana. Fixed a bug where Swain could pull enemies launched by Blast Cones. Q cooldown decreased; bolt angle decreased; now passes through enemies. W range increased; damage decreased; cost decreased later. E cooldown decreased; cost decreased and now flat.

The general and his demon birds are performing fine in Average play, but they do worse the further up the ladder you climb. This is a pretty lengthy refresh, with a mix of buffs and nerfs, so we want to take the time to run through it.

Let’s start with the spice and everything nice: Most notably, we’re significantly increasing his W range (more than double when maxed!). We think this change will be particularly transformative for Skilled Swain players who will be able to impact other lanes from a distance all game long. In addition, we’re also bumping down the cooldown on his Q to help him fulfill his battle-mage fantasy with more casts.

As for the nerfs: to balance out the buffs, we’re pulling back on his movement speed. We’ve also removed his mana restore to skew power away from Swains in low Elo who can profit off of fewer skills dodged, when the reverse happens in higher Elos.

Overall, we’re hoping these buffs will empower Skilled players in both mid and support, with sweeping changes across the board to give him the tools he needs to feel like a more functional mid laner.

Base Stats


Passive - Ravenous Flock

COOLDOWN 12/9/6 seconds (levels 1/7/13) 10 seconds (now scales with cooldown reduction)
removedFLOCK MANA RESTORE Swain's ravens no longer restore mana
BUGFIX Swain can no longer pull enemies launched by Blast Cones triggered by themselves or their teammates

Q - Death’s Hand

COOLDOWN 10/8.5/7/5.5/4 9/7.5/6/4.5/3 seconds
BOLT ANGLE 10 degrees 8 degrees
newHAND IT OVER Death’s Hand’s bolts now pass through champions

W - Vision of Empire

RANGE 3500 5500/6000/6500/7000/7500
DAMAGE 100/150/200/250/300 80/120/160/200/240
COST 70/85/100/115/130 mana 70/80/90/100/110 mana

E - Nevermove

COOLDOWN 13/12/11/10/9 seconds 10 seconds
COST 60/65/70/75/80 mana 50 mana


W cooldown increased later.

We’re hooking some power out of Thresh’s lantern, since pros tend to max this spell earlier than the average player.

W - Dark Passage

COOLDOWN 22/19.5/17/14.5/12 seconds 22/20.5/19/17.5/16 seconds

Twisted Fate

W cooldown increased early and now scales.

Twisted Fate has been able to consistently reach an intimidating state where he can balance both split-pushing and global pressure in Pro and Elite play. As a result, we’re reducing his lane pressure and wave control in earlier phases of the game so that he’ll have to gamble more when picking a card (and a lane!).

W - Pick A Card

COOLDOWN 6 seconds 8/7.5/7/6.5/6 seconds


Passive mana restore value decreased; now scales with maximum mana and champion level; cooldown decreased.

Yuumi was mush, mushed! by her E mana cost nerf in 10.13, so we’re here to follow up (and give her all the chin scratches in the process). As we mentioned in this article, we’re making her passive more important to her success in a way where she’ll need to take more risks if she wants to provide more sustain.

Passive - Bop ‘n’ Block

MANA RESTORE 50-160 (levels 1-18) 25-100 (+8% maximum mana) (levels 1-18)
COOLDOWN 20-8 seconds (levels 1-18) 18-6 seconds (levels 1-18)

VFX Updates

Similar to the previous VFX updates we've made in the past (Ziggs, Thresh, Lux, etc.), we're working on updates to some champion ability VFX. Our aim is to get their VFX up to current League standards and improve gameplay clarity. In this patch, we'll be releasing a VFX update for Ahri and Udyr!

As a reminder, VFX updates don’t impact who gets a VGU, where we take model, gameplay, and thematic into account too. They are simply dev passion projects.


BASIC ATTACK Cleaned up missiles and hit effects
Q - ORB OF DECEPTION New missiles and hit effects, now shows the actual hitbox. Healing missiles are now green.
W - FOX-FIRE New fox-fires, missiles, and hit effects that are cleaned up and modernized
E - CHARM Cleaned up the heart missile to feel more modern and to provide accuracy to hitbox
R - SPIRIT RUSH New cast ground buff effects, as well as new missiles and hit effects


BASIC ATTACK New hit effect
PASSIVE - MONKEY'S AGILITY New movement speed boost effect
Q - TIGER STANCE New transform effect and overhead symbol; Tiger form has a new DoT effect
W - TURTLE STANCE New transform effect and overhead symbol; Turtle form has new shield and heal effects
E - BEAR STANCE New transform effect and overhead symbol; Bear form has a new stun effect
R - PHOENIX STANCE New transform effect and overhead symbol; Phoenix form has new AoE and cone effects


Spellthief's line of items is being overshadowed by the Relic Shield line for AP users, especially enchanters. While it's fine if they're competitive options, the more defensive option should not always be the dominant choice.

Spellthief’s Edge




Shard of True Ice

DAMAGE 45 ability power 50 ability power


Unsealed Spellbook

Unsealed Spellbook has become a dominant choice at the highest tiers of play (Pro and Elite) and often encourages minimal interactions early game. We’re reducing its power a bit so it doesn't outshine other options.
INITIAL COOLDOWN 240 seconds 300 seconds
MAXIMUM COOLDOWN CAP 120 seconds 150 seconds
COOLDOWN REDUCTION PER SWAP 20 seconds with each unique Summoner Spell 25 seconds with each unique Summoner Spell

Nexus Blitz: The Temple of the Lily and Lotus

Nexus Blitz returns with the Spirit Blossom event, now permanently set in the Temple of Lily and Lotus, a long-forgotten temple of the Canghapi vastaya! We’ve got a whole slew of events, from old favorites to brand new ones, along with new rewards, bug fixes, and quality-of-life changes.
