That is what I'm not sure about... when does the ability check if the target is poisoned? I think it's as soon as you press E, not when the twin fang arrives. But then again the cooldown is capped at the exact moment the twin fang hits you... so I'm really not sure how exactly the interaction is.

Let's say the scenario is: She hits the Q, fires her E. While it is in flight you activate QSS, removing the DoT. Will she get another E out? Or will it go on long cooldown? Especially in lategame, when Cassio doesn't need that many hits to kill you it's a very meaningfull difference, and because I don't know the exact outcome, I've always avoided buying QSS against her.
