In addition to taking critical damage from an enemy is this supposed also that your character’s stops attacking? Seems like my character is “staggered” when he takes a lot of damage.
I apologize, I don’t know how to explain better than this.
EDIT: Using the Puncture spell some mobs in addition to interrupting sometimes their attacks have also an icon on their head, which looks like the stun icon. But I have 0% increased stun chance. I checked Puncture and it has no stun effects.
