•Treat Q as permission to play: if it misses, stop spending, but when it lands, buffer the first E immediately and use the speed to stay glued long enough for Twin Fang to keep paying you .
•W is strongest when it ruins the dash or retreat path they still need, not when you toss it out first, so many Cassio fights get easier once Miasma is used like a trapdoor after contact instead of a generic opener .
•Protect Cassiopeia's no-boots tempo by making mid awkward first—crash, plate, recall, then move—because her best map states come from arriving at river mouths and objective entrances with poison and Miasma ready, not from wandering off lane to force a maybe-play .
