Stagger and Status effects Buildup are fine on small enemies but bosses don’t show the status buildup and they recover too rapidly the stagger damage, when you stop attacking a boss their stagger meter it stays still for a few seconds then it goes down almost immediately, it should go down slowly instead, if the boss then needs more total Stagger resistance to balance the changes so be it feels really bad to have almost felled up the stagger bar but then the boss does an attack and and you have to retreat or die and all the work is lost. Also some boss attacks like the Echo Knight charge make them immune to stagger damage (probably due to a bug since it doesn’t seem to be consistent) not only the are immune the meter is oslo counting down so if the meter timing is about to start an they do one of this attacks than I can’t do anything to prevent the boss from regain their stagger damage I think that elemental build up also has the seme problems but i can’t tell for sure without a bar. Also if you parry a boss they recover their stagger meter.
A weird experience I had also with the Echo Knight regarding elemental build up is that most of the times using the same ice rune 3 times back to back would freeze him but one time I used the rune 5 times and it didn’t freeze! This specific Echo Knight was not in the crucible so i’m sure the is not being influenced by the rouge like aspects
