I just discovered that the fel hammer discord faw has a tww s2 m+ boss guide that talk about all the tank busters and a guide for cycling defensives.
I guess I had just started hitting the key level (+7s) that really started to matter in terms of survivability.
as noted in my previous post, mordretha in theater of pain’s reaping scythe was deleting me. the discord advice echos the responses I received here. Gorechop also has some buster treats that I need to plan for better.
great guide for an apparent noob like me
