Sated Caitlyn?
How does that work? I saw someone try it out today but they didn't talk and didn't have sated for very long so I couldn't really notice it. The only interaction I can think of would be headshot, beyond any item effects you want to build.
I don't think the stacking mechanism counts, so it wouldn't help you get headshots any faster. Would it let you double headshot someone? It would need some lucky timing (and probably Runaans), but if you got a headshot ready just as sated went onto its 2nd AA...?
Or maybe it was just for the AS, magic dmg.
