OPENING ENCOUNTERS

Developer's notes
We're making a few quality of life improvements to the Opening Encounter and stage 3 carousel.
Opening Encounter duration has been lowered to ensure you can get in and start low-rolling even faster

CAROUSEL

The stage 3 carousel now always has one of each component unless the carousel contains Spatulas

LARGE CHANGES

TRAITS

Developer's notes
Automata has been one of our most powerful Gold-tiered traits, with the Emblem providing so many defensive stats that it could make any carry, 6-cost or otherwise, too glorious to be balanced. Have you seen Ambessa or Warwick with this and a Bloodthirster!? Chem-Baron has been riding a bull market to the moon. We're decreasing the cashout rewards for 400 and 500 and shipping quite a few nerfs to the Perfected Items.

1-COST UNITS

Developer's notes
Putting the POW! in Powder and raising the power floor of 1-costs in general, with the exception of one chemist who's been on the run for too long.
Powder
Powder Ability Fall Off: 30/30/25% ⇒ 25/25/25%
Singed
Singed Ability Damage Reduction: 50/50/55/60% ⇒ 45/45/50/50%
Steb

Trundle
Trundle Mana buff: 30/90 ⇒ 30/80
Zyra
Zyra Primary Ability Damage: 260/390/585 ⇒ 280/420/630

2-COST UNITS

Developer's notes
Opening up more pathways for 2-cost carries Camille and Zeri to succeed while trimming back some of Renata's stall power and Ziggs' splash damage.
Camille
Camille Ability Damage AD%: 230/230/260% ⇒ 245/245/265%
Leona
Leona Mana: 50/90 ⇒ 30/75
Renata Glasc

Zeri
Zeri AD: 48 ⇒ 51
Ziggs
Ziggs Splash Bomb Damage: 90/135/200 ⇒ 80/120/180

3-COST UNITS

Developer's notes
Giving Cassiopeia a net buff with more Attack Speed which will allow her to cast more often and scale better with items like Spear of Shojin and Nashor's Tooth. While Ranged Gangplank has been able to sail smoothly into many viable comps, melee Gangplank hasn't stayed afloat in the current meta. More healing and a harder-hitting AOE attack will suffice as a replacement for swim lessons here. We're buffing Smeech. It's Smeeching time.
Cassiopeia
Cassiopeia AS: 0.7 ⇒ 0.75
Cassiopeia Mana nerf: 10/40 ⇒ 0/40
Gangplank
Gangplank Melee Ability Heal: 100/125/150 ⇒ 120/140/160
Gangplank Melee Ability AD%: 340/340/340% ⇒ 360/360/375%
Loris
Loris Ability Shield: 525/600/700 ⇒ 600/700/800
Smeech
Smeech Mana buff: 20/80 ⇒ 20/70
Twisted Fate
Twisted Fate Yellow Card: 230/345/535 ⇒ 240/360/560
Twisted Fate Red Card: 110/165/255 ⇒ 120/180/275

4-COST UNITS

Developer's notes
Ekko's both hard to play as an AP-melee carry and a bit on the weaker side. More casts should help him dish out the damage, making the Omnivamp items you should be slamming on him even better. Elise (Ranged) and Twitch are the other two 4-costs that have been dragging behind Silco, Ambessa, Heimerdinger, etc. While they could find success, that success required near-perfect itemization and team composition.
Ekko
Ekko Mana: 0/60 ⇒ 0/50
Elise
Elise Ranged Spell Damage: 200/300/900 ⇒ 220/330/1000
Twitch
Twitch Mana buff: 0/60 ⇒ 0/40

5-COST UNITS

Developer's notes
Jayce's Hextech Forge was triggered too often by instantly casting when revived, allowing you to use it as both a proxy frontline and its intended effect. We're making adjustments that will require you to keep the Forge alive to continually benefit from its effect. We're giving some love to the 5-costs that are less appealing or recently indirectly nerfed (Malzahar's Automata vertical).
Jayce
Jayce's Hextech Forge no longer triggers its effect automatically when revived. Will only trigger its effect if it is alive when Jayce casts his spell.
Jayce Melee Ability AD%: 500/500/2000% ⇒ 600/600/3000%
Jayce Melee Ability Secondary AD%: 225/225/1500% ⇒ 250/250/2000%
LeBlanc
LeBlanc AS: 0.8 ⇒ 0.85
Malzahar
Malzahar Ability Wave Damage: 80/120/1000 ⇒ 100/150/1000
Malzahar Damage Per Tick: 15/22/400 ⇒ 16/24/400

6-COST UNITS

Developer's notes
While Viktor has certainly enjoyed his time as the most glorious of the 6-costs, it's time for Warwick and Mel to compete for the title.
Mel
Mel Ability Damage: 180/450/2700 ⇒ 200/500/2700
Mel Ability Unleash Damage: 1390/3475/99999 ⇒ 1600/4000/99999
Warwick
Warwick Experiment Bonus Stun Duration: 1 ⇒ 1.5 sec
Warwick Blood Hunter Heal: 400 ⇒ 500
Warwick Blood Frenzy AD%: 200/375/2500% ⇒ 240/400/2500%

AUGMENTS

Developer's notes
Dummify has been one of our worst-performing Augments, with the risk of dummifying your team not worth the reward of an additional frontline health pool. We're adding a lot more HP scaling per stage to make this dummy click into a big-brained play. Golemify (Gold) has suffered from a similar issue to a lesser degree. Lone Hero has effectively become the Lux/Vlad Champion Augment over the last couple of weeks, using Lux's shielding to stall fights into an overtime victory. We're disabling it for now but will have more changes to the Champions in the next patch. Arcane Retribution (Sorcerer) was an Augment that asked you to have your Sorcerers die to trigger an AOE of damage with their excess AP. With only one real Sorcerer frontliner (Vladimir), the Augment was unintuitive to play. We've opted to disable the Augment as running vertical Sorcerer, a trait with little frontline, is difficult enough as it is.While inconsistent, Artifactory can lead to some incredibly high power ceilings due to specific Artifact combos that feel unbeatable. While we will be addressing the root of some of those combos later on with a couple of Artifact nerfs, the ability to hit these combos with one Augment is still out of the power budget, even for a Prismatic Augment. One such Artifact is Suspicious Trenchcoat, which, combined with other Artifacts or specific items (Edge of Night), can become too powerful and provide a frustratingly high amount of untargetability. We'll be nerfing Suspicious Trenchcoat later on to account for the dark techs that have emerged with the Artifact, but in doing so, Dark Alley Dealings, which doesn't provide free access to the powerful combos, will be significantly nerfed. We're opting to remove the Augment as it won't be able to compete with other Prismatics.
