Proof that Karthus has 2 Different Ults!

[@HarpE-girl]

It took a long while to figure out the reason behind Karthus R not hitting Neeko. Between trying transforming at specific intervals with Karth R, every different transformable not pet unit, and so on. It wasnt until maybe 6 hours of testing i thought to try it with dead Karthus. FrankTheBoxMonster was a massive help as hes the reason we know its actually two seperate ults.

[@HextechLab]

Thanks again for telling me about it :)

[@AkiRa22084]

@@HextechLab So, which one is the intended one? Jinx R ignores Neeko in minion form, for example.

[@Brain-washed2]

he gave it away with the thumbnail lol

[@user-bl4kb7uf5l]

You can also see the karthus bug in arena! Ulting when you are alive gives you the correct reduced cooldown that it has in arena, but ulting during his passive gives you the normal cooldown and not the reduced arena one.

[@lehung0710]

same, karthus in passive form give the normal countdown

[@HextechLab]

Kled's own health also seems a bit inconsistent. At the same level, items, runes etc. he has 535 max health when mounted up, 534 max health while unmounted (so maybe different rounding), but then again he has 545 health at some point...

[@wverms]

Kled's health also causes really weird interactions with items like Sterak's/Maw (basically things with a health threshold). Been hoping it'd get fixed for a while but alas

[@kuukunanmuna7652]

Too many times I have died without getting unmounted, frustrating since the enemy is also one Q or auto away from dying…

[@animositylol]

@@kuukunanmuna7652 You mean in Arena? It's a known Arena bug, I have never seen it happen in-game unless you have like 1 hp on Kled and die to burn during dismount animation

[@patty4449]

From my time at Riot I actually know whats going on... (They simply forgot to add it) So the thing is this... Karthus basically is 2 Champions (Same for Nidale, Anivia, Quinn and a bunch of others... Yes Morderkaiser in Ult is also a different Morderkaiser) And the code is a pile of sh+t so when adding interactions, new devs don't know they have to add it in 2 files... So the subject is still targeted because its defined as the same object, but since it doesn't have the same stored data in both forms (or simply a different health data in this case) the ult doesn't affect the champ in Minion form... Trust me this happens way more than it should... To all devs, optimise your f*cking codes and make them readable... AND PLEASE leave the comments in... We all love those comments... (Looking at you TF2 devs)

[@patty4449]

P.S. its not just 2 Ults, its 2 different champions, you may find more differences if you dig deep enough, I ain't kidding

[@pedropimenta896]

Found the dev!

[@SwoggersLOL]

interesting when you say morde is two different champs when in ult form, because if you remove his skl, he'll be invisible for both forms. ig morde is duped in ult or something

[@givemebeans2228]

@@patty4449 Bruh riot coding is so shit, i dont understand why dont just reuse the ult code from base karthus 💀

[@HarpE-girl]

Yeah one thing i found much earlier is Kog went a few seasons where alive he had 330 ms meanwhile deadKog had 325 because the buff was never applied to deadKog. Champion swaps are always weird but fun to find interactions with

[@atsukana1704]

The neeko bug and nasfirir slow are legit useful

[@Portos_O_1os]

Imagine if the marker on the first champion never disappeared after he did the 2 headbutt bug, the other champion would get knocked back after every W in the future, unless all-star targets them again and they lose their permanent mark

[@HextechLab]

I forgot to show it, but the check for the mark is only done in some radius around the target, so it wouldn't be globally. But yeah, if the targets stayed close, all-star could just perma headbutt them. And he could even headbutt 5 at the same time. :D

[@yorik1006]

You can do the Alistar W bug in Arena with cooldown reset thing that resets your normal abilities cooldowns every 15 seconds

[@Portos_O_1os]

The Herald recall thing happened to me when they added the mechanic, where all team members who helped get it, get the empowered recall. I was recalling after helping, and my guy kills it 3 seconds before my recall, I examined the clip and I had the empowered recall for that 3 seconds, no more after....

[@thatredkite8310]

Rakan's W knockup zone has infinite range technically. if you spam it in practice tool, the knockup zone might just appear wherever your mouse cursor is at the moment, so if it's hovering enemy fountain, you will knock up in enemy fountain despite being on the other side of the map

[@llotoss]

Bug with Naafiri works because her slow and Stridebreaker's slow are seen by game as the same type of debuff (that can be stacked by some means?..).

[@xTriplexS]

Debuffs are usually aggregated by target rather than aggregated by source, so it makes sense

[@xTriplexS]

If you ignite/exhaust etc someone before the other one runs out, it doesn't increase the duration or the damage, it just removes the second stack

[@xSyleN]

3:53 Using ult as Vi in Practice tool look almost the same. When you ult one dummy and immediately another one both of them are knocked up and take dmg from ult.

[@yez1062]

The naafiri bug is actually broken tho

[@Avatarbee]

You know the Karthus ult bug could easily have been avoided by simply having both ult pull information from the same place so you only have to change something once.

[@CatriusPham]

It's called Single source of truth. Karthus is one of the first champions of the game so I guess they didn't put too much thought into refactoring his code 😅

[@Avatarbee]

@@CatriusPham Here I thought object orientated programming was standard nowadays.

[@OvhanDevos]

The aurora spirits are likely coded as slow moving missles.

[@pinnacleexpress420]

5:42 oddly satisfying

[@MetroArcher]

6:33, it actually is kinda impactful, for example if you help on doing herald and wanna take a recall earlier for tempo, it will consume the herald recall if the herald dies before you end your recall, making you waste the empowered recall. Maybe its intended tho

[@HextechLab]

Yeah, that's what I meant with it probably happening in a lot of games. It happening is not gamebreaking, but it happens often.

[@YawnWoofDog]

@@HextechLabhappened to me once. I was so confused why I did not have empowered recall. Now I know.

[@Lambdaspicot]

Moreover for the Karthus dead ult, there isn't even the audio tooltip for deaf people in the kill feed

[@sagekins4083]

The recall with herald is probably intended or will never be fixed, since it gives you the buff until you recall it would be somewhat of an exploit to recall with it and then have a baron recall for whenever you want for free.

[@kirinomane]

Does Nafiris slow also extend when someone else hits the target with stridebreaker?

[@Ethan-uq2ew]

For the Naafiri Stridebreaker slow, have you tried extending the slow with stridebreakers from multiple different players? I’m curious if that does anything.

[@krodax3639]

How did you enable the notification when karthus ult sounds comes?

[@Ciasteczkowy]

I hate those soft caps on slows. Just remove those and show how much will your slow accualy do! At the beginning of my playing lol i expected 99% slows to be basically roots with no blocking mobility abilities. But it is around 66% instead

[@snapy_knight]

About Aurora spirit vision, Kindred in season 9 also have vision, provided by Wolf when he circles around Lamb

[@pedrodomingues1553]

Also no announcer icon on the dead karthus R

[@Brain-washed2]

the stridebreaker naffiri slow would have been better shown in the same area with the slowed champion walking to the same place so you can really see how much distance is lost. good video though

[@alterranlongbow5067]

the rift herald bug also works without picking up the eye if you get the assist buff

[@muscifede]

is this a naafiri bug or can u combine other short-strong and long-weak slows? maybe some longer abilities slows and short items ones?

[@dawnables2731]

the naafiri slow being able to be extended and refreshed with another slow source reminds me of weaken refreshing in destiny 2 lol

[@vladislavkaras491]

Thanks for the demonstration!

[@demona9699]

3:37 there is a rune that can reset abilities when you kill someone

[@jandalf8128]

There also used to be a bug where if you posessed naafiri as viego her passive would trigger and you got a permenant dog that stuck around even after you stop possesing her. Not sure if it was patched out tho.

[@sageker8208]

That fricken kled bug explains so damm much

[@johanestebanramirezbarrios1411]

4:22 maybe you could do it in arena with augment that reset your basic skills every 10 seconds

[@ToroVtn]

i just noticed dead kathus ult says i am become death lol

[@gamingandchill4186]

With the Naafiri Stridebreaker thing, could it also work on a melee champ with Voltaic Cyclosword + Stridebreaker? Both Naafiri W and Voltaic do the same slow (if you’re melee champ)

[@kayodejohn3753]

I think Aurora's spirits granting vision is a feature.

[@Mr.Normal]

About Alistar's bug, a while ago, I found out that it also happens to Vi's ultimate. I once managed to knock 3 dummies with one ult. You should try one day, It's pretty funny.

[@yamgomes3894]

this karthus neeko interaction happened to me a few hours ago so thank you for reading my mind

[@Daimao-Sama]

The Recall not being empowered is the same with Baron if it is killed after the recall has been initiated

[@lukor-tech]

honestly alistar W should do that, just as skarner picks up champs from under his claws alistar being bigger > more champs targeted during W / Q

[@eatherghost495]

Nilah W also interrupts the ult when timed correctly

[@DanteEhome]

I encontered the empowered recall bug myself.

[@poprostugui]

how did you people even find the alistar bug

[@mister8560]

5:50 Experienced that one a lot, it's pretty annoying

[@engkropix0558]

imagine if karthus' ult code would have taken an animation id parameter AKA riot wrote maintanable code that follows the DRY (don't repeat yourself) principle, hextech would've made a couple dollars less off his videos :(

you should put Neeko's auto attack when transforming to Bel'veth. I couldn't clear enemy wards lol

[@th3j0t46]

I'm pretty sure I've already knocked back 2 champs with alistar in arena. I thought it was intended since I played it once or twice and did not bother to read the abilities lol I have no idea how it happened tho, I can try to check with champ I played with and maybe you can find out

[@SgtMorningWood69]

how about the .15 second trynd ult delay or when it goes haywire if u spam w and try to r during the w animation. i swear im not crazy that ult isnt instacast damnit and it fails ALOT. Source:Trynd OTP

They don't know shit of coding if they did it this way I will explain which was a better way to do it in a way no nerd people can understan They probably coded it this way: If -> Alive -> Use Ult 1 If -> Dead -> Use Ult 2 They could have just do this instead If -> Alive -> Use Animation ult 1 If -> Dead -> Use Animation ult 2 It's obviously more difficult than this, but c'mon

[@thekilleryellowduck]

Average neeko bug

[@Treq4Trak]

Why don't they just rebuild the game in a new engine... Well not because it would take time but it is risky they are afraid of players reaction and what bugs the new version will have. I think they will never do it.

Ight Mr Lab, youre getting on my nerves. You show off all these interesting bugs, and then showcase an obv meta Naafiri build. 🤬🤬🤬🤬🤬🤬
