Proc it using mostly or all autos...
Oh wow! Auto your lane opponent 5 times while they unload their combo on you and proc conq and they disengage so you lose the trade miserably! Amazing idea! I legitimately dont know why high elo players dont auto 5 times in a trade before using abilites!
Or just play someone like Renekton, who can E, auto, E, auto, auto, (conq procced) W, auto, Q
His rage will then likely be dumped on e which is a reeeeealy bad thing for him.
Or Mordekaiser, because it will affect his passive that is up until out of combat.
It will give him a couple more points of true damage per tick early game while giving him a laughable boost in ap. Plus he needs e, auto q, 2 more autos to proc your hallowed and almighty conq in lane.
Or Aatrox, because he has a 3 part Q, another damaging ability, and an auto reset, so its real easy to proc
Q, w, qe, q (his usual lane combo) gives him 4 stacks and blows his chance to reset his auto timer. Next auto is his passive (conq proc) and you know what he has left? Nothing. Autos. Or no, wait, should i autoattack 5 times before using my abilities?
