Any source of damage, bleed or otherwise, breaks the stun. Number one problem k/s have, is they use this skill then follow up with vamp arrow....which removes it. The point of the skill is simply "I'm going to ignore you for now, so stop hitting me". Get's hugely abused in siege, but again....breaks upon damage. I've seen k/w use it in bethomia on the undead mobs with success, so its not a class specific bug.
If you aren't inflicting damage, this would be the first time I've legit heard it doesn't work, and would need to see it for myself.
I'm aware of the break for the stun for holy chains, shackles of light doesn't break. I have tried all scenrios with both skills I could think of, shackles doesn't even hit, period. Holy chains, still flashes on and off regardless of the player not taking dmg, considering it's a instant with no cd, I have literally stood there and spammed it, same result, it's on then off.
Also as I explained, I have had both skills used against me in siege by others, they have worked flawlessly.
Seeing for yourself tbh is immaterial to me blank. it doesn't work on my toon and I have mained knight for many years. Also I don't use vamp arrow when im trying to use a stun/rooting skill that can be broken by dmg lol.
They are as described, plain and simple.
And magio, im aware of how my k/s and k/w work just fine lol. Though I do appreciate the sentiment from you both....
