Mid-scope update, all abilities adjusted.

Despite Olaf’s popularity in Pro, he’s been one of the least mained champions in League for a while now. The flexibility of Ragnarok as an engage or escape and his fast clear speeds make him the ultimate example of a champ that walks the fine line between OP in Pro and “...meh” in all other levels of play.

With this mid-scope update, we’re aiming to shift some of his power away from his clear speed and into tools that will help players feel stronger and in more control of Olaf’s survivability as he rides the edge of disaster at low health. These changes should not only help better define Olaf’s identity as a Berserker, but also allow him to take a new place as a viable top laner.

Mid-scope update, all abilities adjusted.

Get ready to rock and roam because the one and only Stoneweaver is ready to rumble (the ground). Taliyah has been struggling to find footing on the Rift, not only in mid, but in the jungle as well—not to mention the mechanical complexity and punishing nature of her kit.

For Taliyah’s update, we really wanted to focus on making her more fun (especially for players who’ve been playing her frequently), reviving her presence in mid, and increasing the amount of forgiveness in her kit. We’re hoping these changes shake things up and give her a clean slate to start anew!

  • Fixed a bug where Taliyah would sometimes lose her passive permanently if she had a spell shield active
  • Fixed a bug where Taliyah would sometimes not get reduced cooldown on her Q - Threaded Volley when cast on Worked Ground


E cooldown increased. R cooldown increased at all ranks.

Ahri's been getting a lot of play time since her update. She's incredibly consistent at making picks and assassinating carries, all while remaining relatively safe and just out of reach. We're lowering the uptime on her CC and dashes to add more thrill to the chase.

E - Charm

Cooldown 12 seconds 14 seconds

R - Spirit Rush

Cooldown 130/105/80 seconds 140/115/90 seconds


Passive cooldown decreased late. E damage reduction increased.

Everyone’s favorite Poro Protector has been feeling a little left out in the cold recently. We’re hoping to bring a smile back to his glorious mustache (and his poros’ faces) by beefing up his protective power.

Passive - Concussive Blows

Per-Target Cooldown 8/7/6 seconds 8/6/4 seconds

E - Unbreakable

Damage Reduction 30/32.5/35/37/40% 35/40/45/50/55%


Q AD scaling increased. W cooldown decreased.

Hecarim is hecc'in weak after the last set of nerfs targeted at his tank build. We're helping him get his hooves back in the game (while being careful to avoid reintroducing his one-shot E build) by buffing his item scaling and increasing the horsepower behind his key survivability skill to more evenly distribute his power across his kit. These should help Hecarim find a more stable place in today’s meta without turning him into a pseudo-assassin race horse.

Q - Rampage

Physical Damage 60/90/120/150/180 (+85% bonus AD) 60/90/120/150/180 (+90% bonus AD)

W - Spirit of Dread

Cooldown 18 seconds 14 seconds

Master Yi

R bonus attack speed reduced.

The Wuju Bladesman has gotten a little too fast at killing his enemies, especially in late game. We're reducing his DPS scaling to slow him down and give his foes a chance to keep up.

R - Highlander

Bonus Attack Speed 25/45/65% 25/35/45%


Base health reduced.

Nidalee's been catching prey left and right with her recently increased spell output, especially at higher levels of play. We're bringing down her early dueling power so she doesn't get such an easy Nida…lead.

Base Stats

Base Health 570 540


Passive grey health conversion increased. Q mana cost increased, mana refund increased, now refunds mana upon hitting an enemy champion. R cooldown decreased, “Your Cut” opportunities reduced.

Pyke's been a little bone skewed toward mid ever since his changes long ago in Season 9, so we're reverting them to bring the Bloodwater Ripper back to bot lane. We're also adjusting some other parts of his kit to further tune him toward the unconventional support he is. Kills (and bags) secured.

Passive - Gift of the Drowned Ones

Damage Converted to Grey Health when near Two or more Enemies 40% (+0.5% per Lethality) 45% (+0.5% per Lethality)

Q - Bone Skewer

removedLIGHTER POCKETS Pyke no longer receives “Your Cut” gold upon successfully executing enemy champions with his R (last assisting ally will still receive “Your Cut”)
removedBOGO IS A NO GO Pyke no longer receives additional “Your Cut” gold when allies kill enemies within Death From Below’s execution area

Renata Glasc

Base armor decreased. Passive damage decreased.

Renata Glasc is on her way to monopolizing bot lane at all levels of play, and business is really starting to boom in Elite. She's been getting a bit too much value prop out of her passive, whereas her return on investment for damage-oriented support items has been relatively low. These small adjustments toward AP item scaling should help balance and diversify her build portfolio.

Base Stats

Base Armor 29 27

Passive - Leverage

Additional Magic Damage when Renata Marks a Target 1-3.5% (levels 1-13) (+1% per 100 AP) 1-2% (levels 1-9) (+2% per 100 AP)
Additional Magic Damage Against Marked Targets 1-3.5% (levels 1-13) (+1% per 100 AP) 1-2% (levels 1-9) (+2% per 100 AP) (damage against unmarked targets unchanged)


Health and AD growth increased. W base damage increased, cooldown increased early and decreased late. R base damage increased.

Renekton has largely disappeared from Pro after the fighter item changes in 12.3. We're looking to add some scaling back so he feels a bit better as the game progresses. We're also reducing the gap between his W and E second max builds since that choice leads to some serious win rate losses in Average play. You heard it here first, crocs are back in fashion.

Base Stats

Health Growth 92 97
AD Growth 3.75 4.15
AD at Level 18 132.75 139.55

W - Ruthless Predator

Cooldown 13/12/11/10/9 seconds 16/14/12/10/8 seconds
Total Physical Damage 10/30/50/70/90 (+75% AD) 10/40/70/100/130 (+75% AD)
Total Physical Damage when Empowered 15/45/75/105/135 (+75% AD) 15/60/105/150/195 (+75% AD)

R - Dominus

Magic Damage per Second 40/80/120 (+10% AP) 50/100/150 (+10% AP)


W damage against monsters decreased.

Rengar’s changes in 12.7 helped this kitty adapt a little too well to the outdoors to the point where he’s now the top cat in the jungle. We're reverting a buff to his clear (and that buff only) to otherwise leave him as is.

W - Battle Roar

Damage to Monsters 85-150 (levels 1-18) 65-130 (levels 1-18)


  • Fixed a bug where Rengar’s empowered abilities and W - Battle Roar’s heal would sometimes play through the Fog of War


W damage tick rate decreased.

We’re introducing some small quality of life changes and a batch of bugfixes to help fan Shyvana’s flames.

W - Burnout

Damage Tick Rate 1 second 0.5 seconds

E - Flame Breath

newThe area of effect zone from Shyvana’s E - Flame Breath now applies marks to enemies that enter the zone.


  • Fixed a bug where Shyvana’s Q - Twin Bite would not attack player-created targets (like Teemo’s Mushrooms or Illaoi’s Tentacles) twice
  • Fixed a bug where Shyvana’s Q - Twin Bite’s second attack would not deal damage if the enemy was running away from her
  • Fixed a bug where Shyvana’s W - Burnout VFX were not correctly displaying when inside of Mordekaiser’s R - Death Realm


Undead Sion's Passive damage against structures reduced.

Sion's been a bit too glorious in death. Although "inting Sion" had a good run, we believe it isn't a sustainable direction for him or League in the long term. Taking down towers by split pushing should certainly be doable even while behind, but when the strat requires repeatedly dying, it’s not very fun for all parties involved. We're nerfing undead Sion's split pushing power in order to restore some balance to his circle of life.

Passive - Glory in Death

newNOT A WRECKING BALL Sion now does 60% reduced damage to structures while in his reanimated frenzy form (includes runes and items)


Passive AP and Bonus Armor per Soul increased. W shield strength scaling with Souls increased.

What is the value of a soul? (Currently, not very much… ) Thresh has fallen off quite a bit, particularly in Average and Skilled play, so we're increasing his scaling power by making it more worthwhile to collect the essence of the dead. Gotta catch 'em all.

Passive - Damnation

Ability Power and Bonus Armor per Soul 0.75 1

W - Dark Passage

Shield Strength 60/90/120/150/180 (+1 per Soul) 60/90/120/150/180 (+2 per Soul)


Passive attack speed gained on minion and champion kills increased. W magic damage on-hit increased.

Varus has been relatively weak since his Lethality nerfs last season. We're buffing his on-hit builds back up to make his vengeance viable again.

Passive - Living Vengeance

Bonus Attack Speed on Non-Champion Kills 10/15/20% (+15% bonus Attack Speed) 10/15/20% (+20% bonus Attack Speed)
Bonus Attack Speed on Champion Kills 40% (+30% bonus Attack Speed) 40% (+40% bonus Attack Speed)

W - Blighted Quiver

Bonus Magic Damage On-Hit 7/10.5/14/17.5/21 (+30% AP) 7/12/17/22/27 (+30% AP)



Hullbreaker is an important tool for empowering split pushing, but when rushed as a first item, its bounty-ful bonus resists can invalidate laning and lead to unpleasant experiences. We still think it's a valuable addition to the game since, unlike past split push items like Zz'Rot, Hullbreaker requires champions to stay in the lane they’re split pushing. So we're nerfing its early game potency.

Champion Bonus Resists While Hunting Alone (Melee) 20-60 (levels 1-18) 10 (levels 1-11), then 20/35/43/51/59/67/75 (levels 12-18)
