i wonder if the Ancient Parthan Defenders work and how i see it. i wanna proc the damage reduction of the APD with my Cyclone Strike (Wall of Wind). But i don't see any buff or change in toughness. Also i dont feel any difference in the damage i take..
Cyclone strike is a knock-up effect, not a stun. And the item only works while the mob is under the effects of the stun. If the stun only lasts 0.5s, you only get the damage reduction effect for 0.5s. You may know this already, I only point it out because if Cyclone Strike is your only "stun" ability you would never get much benefit from these bracers anyway. SSS with the frost rune is an example of an ability that synergizes well with that item. But keep in mind diminishing returns on elites. If you carry onwards with this build, when you reach the point where elite fights last more than seconds, the usefulness of this item goes down the drain, at least for GRs.
This is old, and simply states without pointing to any testing, but... I can't help shake the feeling that they are indeed different effects. I was still totally off with the SSS suggestion though, because that's a frost effect too. So yeah, I don't see great potential for this item with the current end-game monk builds that are being used.
And easy way for you to test it is to try it with a couple of freeze abilities (to confirm that it doesn't work with frozen enemies) and then with abilities that specifically stun.
