Did stack stuns or not?

Lets say i have Tidehunter with refresher, and one stun is about 2,5 seconds, so i pres immedeately twice R button, so i ask if its wokr like 5 second or that another stun will override the first stun so it will be only lets say first stun last 0,5 second so totally 3 second, so i ask if i want full duration stun i have to wait till first ravage stun ends or i can press r imedeately twice?

You have to wait until the Ravage stun duration will end, and then click R once more. Good players will waste like 0,2 seconds of first Ravage stun before they will activate a second one.

You mean waste 2 second, becouse if you wait only 0,2 second than you waste many stun durion time, but i think its best use another ravage imedeately when first ravage ends.

He means that only 0.2 seconds are still left from the previous stun. And no, it is not.

I'd assume that using it just before the other Ravage ends prevents fast opponents from using a or something before you hit them with it.

Like if you were quick enough you could probably blink out just before the second ravage affects you.

The small out of wasted time pays out because it still prevents the opponent from doing anything for a long period of time with acceptable wastage.

I mean, that's why I'd assume it's best to do it 0.2 seconds before the primary stun wears off.

On an unrelated side note, because the ravage stun moves outwards if your quick enough you can blink towards tidehunter and not get stunned and then beat his face in=teamfight won
