See a lot of confusion about diminishing returns on sleep.

30 seconds the first time then reduced 50% each time after.

Purify is a given, so if you get slept and it is cured or you use a CD or get hit the next is half the previous.

So many here say 10 sec base - any resistances = ?

Then purify or cure 3 sec sleep then 1.5.......

There is no point instant stunn is better at this point over a 2 second cast ability that can be instant every 1 minuite with swiftcast.

Should wait and see how gear reduces the duration. Each cast will be for less duration as well as getting cut in half each additional cast
