Silver Shroud not working as intended -> damage slips by 1/10 of the time

What went wrong?

I died to a basic attack from a scorpion while having 6 stacks of Silver Shroud. Unfortunately, I wasn’t able to clip the moment when I had all 6 stacks active, but I did capture the damage I received right before dying.

I’ve experienced multiple deaths like this throughout the day, which is incredibly frustrating, especially since the shroud is supposed to be my strongest layer of defense.

Here is another example, where I die with a silver shroud stack still on my character. By duration you can see that it is the same stack before and after I die cause it continue to tick down.
Went back and made another clip to show that it works against the same attack (https://youtu.be/UZEHYcDOeaw), just not everytime. It’s frustrating.
