[GAMEPLAY] Aatrox's W doesn't proc when built Sated Devourer

I'm currently playing a custom game as Aatrox, and I kept on seeing this weird bug he has. Apparently, his W randomly procs & not procs whenever he attacks someone. Most of the time, his W doesn't proc at all when hitting the Crab. Or sometimes in some jungle camps, his W would stubbornly procs & not procs. I think this is the one big reason why his playrate isn't so well.

How to create bug:

1. Select random targets.
2. Autoattack it.
3. Sometimes W doesn't work, while other targets may work.

......and I just fought a Jax bot full-handedly 1v1 solo, and my W doesn't work at all.
