Sorry, it may have been unclear to what I was responding.
My claim is that it’s hard to get to the point where you reliably walk in there and 1-shot him like I could on Zekvir last season. This is largely due to uncontrollable RNG like Brann being on the other side of the map when Underpin decides to jump over to him and then immediately summon Cronies.
I am definitely not saying you can’t beat this guy in delve gear. Heck, I beat him at ilvl 641, which isn’t even good delve gear.
