I have around 80% block chance. But as the others pointed out, DA and avoidance will prevent that every attack will be blocked. Some will be missed or avoided. But that was not the core problem here. The problem for me is how the following assumption will work out:
Assume we have 100% Block Chance, -100% Block Recovery, and 100% on Block proc from Relic AND we have no avoidance at all and not enough DA to be missed. Also notice that the skill from Reckoning Relic has no CD.
Now lets assume we will get hit by lets say 3 enemies in the same timeframe.
Now comes the crucial question for me: Do those 3 enemies would get debuffed by the Reckoning skill all at the same timeframe?
