Lore[]

  • Biography
When the prophet MalzaharSquareMalzahar was reborn in Icathia, he was led there by an ominous voice which thereafter anchored itself to his psyche. From within, this voice bestowed upon him terrible purpose, and though Malzahar was no longer tormented by its call, the voice did not cease its unrelenting summons. This baleful beacon's gentle flicker - now fastened to Runeterra - drew forth a putrid beast that ambled across a threshold it did not understand, widening a fissure between the spaces which were never meant to meet. There amongst the haunting ruins of Icathia, Kog'Maw manifested in Valoran with unsettling curiosity. The spark which led him to Runeterra teased him still, urging him gently towards Malzahar. It also encouraged him to familiarize himself with his new environment, to the stark horror of everything he encountered on his journey.

The enchanting colors and aromas of Runeterra intoxicated Kog'Maw, and he explored the fruits of the strange world the only way he knew how: by devouring them. At first he sampled only the wild flora and fauna he happened across. As he traversed the parched Tempest Flats, however, he came upon a tribe of nomads. Seemingly unhampered by conventional rules of physics, Kog'Maw consumed every nomad and any obstacles they put in his way, amounting to many times his own mass and volume. The most composed of his victims may have had time to wonder if this was due to the caustic enzymes which stung the ground as they dripped from his gaping mouth, although such musings were abruptly concluded. Even this feeding frenzy did nothing to satiate Kog'Maw's appetite. His swathe of destruction continues still as he is inexorably drawn towards Malzahar. What happens when he finds him is anyone's guess.

"If that's just hungry, I don't want to see angry."

Patch History[]

Patch 11.9

Q resistances reduction increased. E cost decreased.

Kog'Maw has been in a cocoon more than he’s been in the bot lane, so we’re giving him more ooze to get back in the groove. In addition, we're helping him burn through more enemies that dare stand in his way... or in his spit.

Patch 11.5
W bonus damage increased later.

Once upon a time, when tanks and fighters only built armor Legendaries like Sunfire Cape and Randuin's Omen, Kog'Maw was much more able to dissolve defenses and have lower cooldowns. To give him more of a payoff, we're amping up the zip in his spit so that when the ability is up, he can charge! bugle noises

Bio-Arcane Barrage W - Bio-Arcane Barrage

BONUS DAMAGE : [3/3.75/4.5/5.25/6% of target's maximum health] ⇒ 3/4/5/6/7% of target's maximum health


Patch 11.2 - January 21st Hotfix

Caustic Spittle Q - Caustic Spittle

BUGFIX : Kog'Maw no longer permanently loses bonus attack speed after dying


Patch 10.18
Base health and armor growth decreased.

This caustic caterpillar-creature is almost always toeing (and oozing around) the line, and he’s finally crossed it. In response, we’re lowering his defenses to highlight his identity as a glass cannon marksman: severely spitty, but slightly squishy.

Base Stats

HEALTH GROWH : [90] ⇒ 85
ARMOR GROWTH : [3.5] ⇒ 3.25


Patch 10.13
Q damage ratio increased. R damage ratio increased.

Although his standard build has been doing well, AP Kog’Maw hasn’t been oozing much confidence recently. We’re bringing some enzymatic excitement for players to experiment with alternative builds around his AP.

Caustic Spittle Q - Caustic Spittle

DAMAGE RATIO : [0.5] ⇒ 0.7 ability power

Living Artillery R - Living Artillery

DAMAGE RATIO : [0.25] ⇒ 0.35 ability power


Patch 10.11

The marksman class has major durability problems, especially in the early laning phase where their power feels heavily reliant on their supports. This has been causing issues in gameplay satisfaction since a marksman's strength relies on the length of time they're alive. By increasing their mobility (via items) and base health, we feel that ADCs won't be punished so aggressively when they fail and will still have a chance to bounce back and unlock their power in fights. That being said, we've heard your concerns about the bot lane marksman champions that can also solo lane like Lucian and Vayne. We're giving them a separate set of changes which you can find more details on below. We’ve also omitted Corki, Kindred, Quinn, Senna, and Graves due to having their primary playrate in other lanes, with the understanding that Senna may be considered for similar changes in the coming patches.

BASE HEALTH : [500] ⇒ 530
BASE HEALTH GROWH : [86] ⇒ 88


Patch 10.1 R mana penalty duration now displays on icon.

Living Artillery R - Living Artillery

DEBUFF DISPLAY : Kog'Maw's mana debuff duration now displays on R's border


Patch 9.21
Base stats rounded up. Q and E base damage increased.

Right now, Kog'Maw's E does not feel rewarding to cast, even when it lands successfully. Rather than decreasing the costs on his E's or other abilities' early ranks, we're upping their value so that Kog'Maw’s kit still has a risk vs reward element.

v8.19
Base movement speed increased. R range increased.

In a meta that often sees two or more tanks on a team and short-range ADCs in bot lane, Kog’Maw has been surprisingly absent. We’re giving him some base movement speed to help him kite aggressively and go for trades against some of those short-range champions like Kai’sa and Xayah. Early game buffs to his ult’s range will also help him chase down opponents after ganks or trades.

W maximum health damage increased at later ranks.

We went too hard on W last patch, so we're giving some of its strength back.

v8.3
W maximum health damage decreased at later ranks.

Kog's damage is spiking too hard, even with one item. Less damage from his main basic attack murder tool should force him to rely more on items.

Bio-Arcane Barrage W - Bio-Arcane Barrage

v7.22

v6.21
Mana cost per R cast down, damage up.

Back during the Marksman Update, we shifted Living Artillery to be more about executing enemies as they back off, rather than a primary damage tool in its own right. Now that Kog’Maw’s back to his old kiting/spellweaving ways, he’s frequently casting his ult (and stacking its mana cost) while foes are well above the execution thresholds. This leaves Living Artillery feeling pretty lackluster. So, we’re re-tuning it to fit better into Kog’s new (old?) playstyle while holding on to some of the spicy execution feeling we gained from the Marksman Update.

Living Artillery R - Living Artillery

COST : [50 mana + 50 per cast (500 mana maximum)] ⇒ 40 mana + 40 per cast (400 mana maximum)
MANA DEBUFF DURATION : [10 seconds] ⇒ 8 seconds

EXECUTION THRESHOLD 1 : [Deals 200% damage to targets between 25% and 50% health] ⇒ Deals up to 150% damage to targets approaching 40% health
EXECUTION THRESHOLD 2 : [Deals 300% damage to targets with less than 25% health] ⇒ Deals 200% damage to targets with less than 40% health


v6.20
W animation improved to match updated effect.

Getting this out of the way: we don’t have buffs for Kog this patch, and that’s why he’s at the bottom (your winrate joke goes here). Reverting an update after it’s settled is really a new update in itself, so we expected Kog’Maw’s performance to drop while players re-adjust to the attack speed cap. We’re holding off on the (im)balanced call until he stabilizes, since hasty changes now will just incur more adjustments down the road.

That aside, Bio-Arcane Barrage’s visuals felt pretty out of place with the changed functionality. We’ve fixed them up!

Bio-Arcane Barrage W - Bio-Arcane Barrage

SPIFFY SPITTING : Made Bio-Arcane Barrage’s attack animation cool again
LION VOMIT : Updated Lion Dance Kog’Maw’s hit particles for even more fireworks
8 SECONDS : Updated Bio-Arcane Barrage’s visual effects across skins to match the new duration


v6.19
Q and W have been reverted to their pre-update paradigms.

Let’s start with the bottom line: Kog’Maw’s being partially reverted to his pre-2016 status. While we’ve had champions that take a couple of passes to get right (...Ryze), this is the first time we’ve actually gone back on a Champion Update. To understand how we got here, let’s take it all the way back to last year’s pre-season.

Our goal for the Marskman update was to create strategic identities for them outside of ‘who does the most damage’. What does each marksman do that their classmates don’t? Kog’Maw already had an answer to that question: be the glass cannon, demanding an entire team’s resources to support. So rather than create a distinct identity, we took a different approach: sharpen the one he already had. If ‘glass cannon’ was cool, could we push things further and make a ‘glass turret’?

10 months and 5 attacks per second later, how did that shake out? Well, Kog’s gameplay has actually moved away from the niche he previously filled. Transforming into an immobile turret is certainly unique, but it creates a ‘feast or famine’ situation. Kog can’t move between attacks in the late game, so either he mows down everyone in range, or enemies walk to safety since Kog can't keep pace. Compared to the consistent payoffs of old-school ‘Jugger-Maw’ comps, playing with today’s Kog’Maw feels too hit-or-miss.

As an aside, new Kog's created some warping effects on the items system. Specifically, on-hit items (Rageblade, Wit’s End, even Skirmisher’s Sabre) are balanced with the attack speed cap in mind, and Kog'Maw's pushing the strength of these effects past their designs. This puts heavy restrictions on the item system, all to support a single champ.

All said, we’re left with two choices - continue to make concessions toward Kog’Maw’s ‘glass turret’ ideal, or hit the reset switch to a stabler (though still imperfect) Kog. The updated kit's moved too far from what made Kog’Maw special, so we opted for the latter. This transition may be choppy, as many of League’s underlying systems have changed since Kog'Maw's update, but we’ll be monitoring how he readjusts and make any changes necessary to support him.

Q shred up at early levels. W damage down.

When last we joined Kog’Maw on his adventures through patch notes, we spoke a lot about giving hypercarries a more even power curve than just ‘great late, awful early.’ These changes are furthering that philosophy, letting Kog feel like he gets to have a Q and reining in his insane power spike.

v6.5
Attack speed per level up. Q cost down. W has a base damage, but no longer grants any attack speed per rank.

Before we talk 6.5, let’s talk about how we got here.

Kog’Maw’s identity is one of the clearest we have in league - a baby voidling that if sheltered and protected, grows into a hyper-carrying win condition all his own. Historically this has been done through balancing his laning phase to a state where it’s nearly impossible to withstand aggression, given that the rewards for succeeding were that you’d have an extremely powerful Kog’Maw on your team. Cut to the Marksman Update for Preseason, and now Kog has an additional tradeoff for his power - specifically ‘can you engineer a fight such that he can stand still and obliterate everything in sight’. Granted, the tradeoffs between high damage and mobility isn’t actually ordinary for a Marksman - they usually kite and fight simultaneously. Understandably, the early days of Kog’Maw’s update were a rough learning time for us all. We had a glass cannon that was all glass and no cannon.

So we thought, ‘If he’s not performing, let’s give him some love in a way that boosts his laning phase!’ That was 6.3. Terror ensued.

Back in the present, we’re looking to make a sustainable Kog’Maw for the long-term, free from the binary teeter-totter of ‘really strong or really weak’ that hypercarries tend to fall into. The changelist below represents a shift in thinking about Kog’s power curve - he’ll still scale incredibly with items, but that curve is now more even across the game (rather than spiking at any one particular point). Smoothing this curve means that Kog’s lane can be in a state that’s relatively normal compared to his peers, but the ‘race against the clock’ should feel less harsh for those that fall behind. Kog’Maw may always be the posterchild for what the term ‘hyper-carry’ means in League of Legends, but the hope is for that term to extend beyond just ‘bad lane, great late game’ and into meaningful interactions between the champions and their environments.

v6.4
Attack speed down.

Since easing up on his laning-phase leash in 6.3, Kog'Maws taken revenge on his oppressors in a truly gruesome fashion. None would disagree Kog needs to be toned down, but let's go in-depth on the tactics. Toning down his attack speed might seem counterintuitive considering he's supposed to be a cute, corrosive machine-gun, but it's all about creating windows of power that are more nuanced than 'strong all the time.' Striking his core stat pushes Kog'Maw to be more careful around how he manages Bio-Arcane Barrage's uptime, as he'll be much less of a face-melting menace without it. Final note: you can consider this a two-part changelist as we dive deeper in 6.5 to see how we can get Kog to feel good about his abilities (Q and R in particular) when he's not right clicking and standing still.

General

BASE ATTACK SPEED : [0.665] ⇒ 0.625


v6.3
Q's attack speed passive shifted to W. W now has a minimum damage.

Now the definition of 'Glass Cannon' in League, Kog'Maw finds himself a little too brittle to get out of lane and into a state where he can aim for a high-scaling fantasy. The primary goal is to clean up Kog's rank-ups to feel less like a trap and help him smooth out that transition from 'free kill botlane' to 'hyper-vomit omnicarry' without just handing him a free pass. (Trivia: did You Know that previously ranking W gave you no increase in damage? Sorry about that.)

v5.24
W’s attack damage ratio is gone, but now has a base damage.

Kog’Maw’s the same vomit-happy hypercarry he’s always been, but the update went too far in removing base damages from his kit. What we end up with is a Kog that’s incredibly hard to stop once he gets going, but lacking in the tools to get there reliably. Removing the ratio and reinstating the base does trim Kog’s highs, but gives him an expected damage floor to tap into when he’s not consuming everything.

Bio-Arcane Barrage W - Bio-Arcane Barrage

ATTACK damage ratio No longer deals 1.25% per 100 attack damage of the target's maximum health as magic damage
FLAT damage Now deals 2% of the target's maximum health as magic damage


v5.22

When someone says Kog'Maw, the word 'hypercarry' is never far behind. Already one of the most strategically distinct marksmen, we're pushing him above and beyond - disregarding the attack speed cap, the enemy's composition, and even their feelings. Power does come at a price however, so while Kog is busy spewing acid (and whatever else) onto his foes he's unable to budge without giving up his unparalleled damage stream. A well-protected Kog'Maw will bring down anyone, anywhere, but leave him out to dry and he's just another Kog in the machine.

"When we made our AD itemization changes back in 4.10, Kog'Maw got significantly stronger on top of his already strong base kit. We still want Koggles to hit his late game power, but in order to get there he needs to have a real weakness in the early to mid game. As a quick rundown on why these changes specifically: Kog's current favored item build (Trinity Force + Blade of the Ruined King) lets him build more utility / tank than traditional Infinity Edge marksmen, but he can still deal tons of damage with Q's high base shred + W's damage amp. Now he'll just take a little longer to hit that level of effectiveness."
