[GAMEPLAY] HoB fails to activate until 2nd attack. (Exists in 10.3; has existed since release)
I originally posted this in Riot's "Bring Us Your Bugs!! Celebrating 10 Years of LoL" thread, and now I am finally turning it into its own thread since Riot didn't do anything back then. Original post is here: https://boards.na.leagueoflegends.com/en/c/developer-corner/w9EtnBBk-bring-us-your-bugs-celebrating-10-years-of-lol?comment=0068
There is a bug with hail of blades that you can trigger on all (or most) champions where the rune does not activate on your first autoattack, but activates on your second autoattack instead. Meaning you have to endure one really slow autoattack with a really slow animation before you can get your 3 fast hits (1 slow AA -> fast AA -> fast AA -> fast AA). The problem is, it only triggers on some machines (even though the game is supposedly played server-side). Last time I posted this bug, I heard through a friend that Riot could not reproduce the bug at all, despite all my videos. But I can reproduce it 100% of the time (as can others). I had honestly given up on this bug and just stopped using the rune entirely (and switched to Conqueror, even on champions/builds that would do better with hail of blades). Why Riot never reached out to me in the past to troubleshoot the bug and find out why my hardware/network setup can trigger the bug (and theirs can't) puzzles me, but maybe this time they will. The bug is easier to trigger on some champions rather than others. I can trigger it VERY easily on Master Yi. I can fight in the practice tool for a few minutes and reproduce it on Xin Zhao, but it is harder. I have heard reports from others of this bug triggering on various other champs (including Udyr). I originally reported this bug on patch 9.9. It has existed longer than that (this patch was the patch I started using the rune due to a mini Yi rework - I had never used it before that, and therefore could not discover it before that). The bug still exists.
How to reproduce: I originally tested this bug on Master Yi. It is easiest to trigger on Yi (out of the champions I play). The easiest way to trigger it is by pressing Q on a target, and then spamming (as fast as you can) E+R+right click on your target so that you will use E + R + autoattack at the same time as soon as coming out of Q. But you don't need to do this, this is just the easiest way to reproduce it. If you get unlucky you can reproduce it by simply pressing Q once and nothing else (automatically attacking the champion when coming out of Q, without even right clicking).
Why this is gamebreaking and not just a minor bug: you can literally turret dive and then get kited (or flashed from) and your rune just killed you because you didn't kill your opponent. lol.
And here is the evidence: I will start with a harder champion, Xin Zhao. I made this video after getting frustrated when the bug triggered 4 times in one game on Master Yi. At the time, I did not know the bug could trigger on all champions. So this video made me come to that sad realization:
Watch my attack speed. When I reproduce the bug correctly, my attack speed will drop to 0.9 for one very slow attack, and then my attack speed will jump to 1.6 and perform 2 hail of blade attacks (knocking up on the second one) followed by one final (3rd) hail of blades attack after the knockup. So, slow AA -> HoB AA -> HoB AA + knockup -> HoB AA. I reproduce it a few times at the beginning, I fail miserably to reproduce it through most of the middle, and then I reproduce it several times at the end. I am spamming right click, E, and Q. But from what I know about Yi, the bug can trigger randomly, even if I am not spamming buttons. I used the "take my abilities off cooldown" button but I didn't leave it automatically enabled (I manually took my abilities off cooldown after each combo). So this isn't just a practice tool bug. You can reproduce this in a live game.
Now, I will show my evidence using Yi. This is a LOT of videos, so please bear with me. (Also, reminder: if you are having trouble seeing it, you can slow the videos down).
This video shows it very clearly. My R activates first, then my E, and immediately when the E appears on the buff bar (and goes on cooldown) my attack speed drops: https://youtu.be/jRl9_WPTIjw
In this video my R is activated before my Q, and my attack speed drops as soon as my E activates after I come out of Q: https://youtu.be/oJQgYqYrW5U
Another game, another HoB bug: https://youtu.be/77QWC61aayY
Another game, This time I didn't even press E or R https://youtu.be/u4slYessda0
Same game, another bug: https://youtu.be/ssqCEhrTfxA
Bug happened twice in this game. Denied me 2 kills. https://youtu.be/6fXe7s1KYKo https://youtu.be/m3Ti6s03FYM
Just had the bug happen 4 times in one game. This video is all 4 instances in one video. https://youtu.be/tScy_eDefwE
And below is the same game where the bug happened 4 times, but this is NOT a video of the bug. This is 2 instances where hail of blades actually worked properly. #This is how hail of blades is supposed to work. https://youtu.be/jlAQ89LfAKc
