After last week's patch mirumok is a lot harder. I am getting more damage by the monsters I was Guardian level 62 now I switch to nova 62 293DP with Tet kutum and nesser gear and I am getting almost one shotted by monsters nova is way too weak or mirumok just got harder ?

U need +320DP.

I didn't notice differences (and I don't read nothing about Mirumok in 16 and 23 june patches). Maybe did you get damage by the  small circle aoe from Mirumok Watchers (those spawning Voraro)? The mechanics is quite forgiving but if stay inside too much, you get a good chunck of damage.  About DP, 300-310 is enough,  even at night, but go there buffed.

No difference for me too (in Succession).

If you're quite OS, same with 293DP it is probably due to Vovaros (red circle stacks are deadly). I noticed they do damages a little later than before : no more if you're into red circle when they spawn, but just after, when red circle disapear.

293 for Nova is not 293 for Guardian, Nova is super squish compared to her. I won't even touch Miru at 300 on most classes. Striker, Warrior, Guardian and Mystic are the only ones that can do it that low.

u see issue is that guardian is too tonky. and someother classes as well in pve.
