Critical Kai'Sa bug, needs Immediate Disable.
I was playing around with Hail of Blades/Rage Blade Kai'Sa in a custom game when I noticed something very strange. After attacking a few Champions I noticed I was getting 2 proc's of her passive off with 1 hit. At first I thought that it must have been the Hail of Blades making her attack too fast for me to notice the second auto, that's when I started attacking jungle camps and noticing the same thing.
Curious, I saved the replay to try and understand what was happening. Looking at the video I thought it was due to me Auto Attacking and pressing E at the exact moment the Auto Attack landed. You can see what I mean here.
After viewing the replay I tried to recreate the conditions and sure enough I was able to get her to double Proc with 1 auto but... It was not only because I E'd at the correct time. After I was satisfied with the results I decided to just auto the dragon for fun before I exited and that's when the bug became a serious issue. Just standing and auto attacking prompted Double Proc's for only one auto, every auto. You can see what I mean here.
So a fun little bug that I discovered that was not in its self serious because it had to be replicated under precise circumstances has become game breaking due to the unpredictability of the double proc's from Hail of Blades.
There is clearly something extremely wrong with Hail of Blades/Rage Blade Kai'Sa. From what I can tell the second proc of the passive does no damage, It just allows you to stack your passive twice as fast resulting in an extreme amount of damage in less than 1 second as you can proc your 5 hit passive in 3 auto's. And with Hail of Blades, those 3 auto's take less than 1 second. Here are the Runes I used to create this bug.
See if you can replicate it in a custom for yourself. Just don't do it in a normal/ranked.
