Mobility

While training at Twisted Jesters, I could never use a pot while poison breath's or teleport's animation was active; similarly, on my aran, I couldn't use a pot while attacking with it. I don't lag at all, so it can't be that.

Then I guess the thing must be that some attacks cause what I call "pot lag". Shadow web is another one, now that I remember. Maybe attacks that cause an area of effect over time attack cause it. And what I meant with triple throw is attacking, and withing a fraction of a second, pot, then, wait for the lag to wear off, keep attacking. No attacks can scape pot lag. Not even standing up if you were sitting.
