I was playing on master difficulty when I ran into this bandit with a 2h hammer that would one shot me, I tried to kill him but I couldn't so I ran into this caged and he could not get me but I was able to still hit him. What are your guys thoughts on abusing these mechanics?

Here is the video, of what I was doing so you have a visual of it!
