A friend and I got shadow trap at level nine in the arena. We fought him for over an hour and literally only took off one quarter of his health.
We were basically out of ammunition and options and just saved and quit.
One of the problems was his shield would constantly rebuild and I am not sure what the triggers are that caused that.
Is it just a set piece amount of time and then his shield will rebuild? Or does attacking other enemies and not constant damage to him cause it to rebuild.
I was a Wilhelm and the other player was a Nisha who was dealing massive damage with a luck Canon and still not seeing results.
It was a very strange fight. As both of us were able to stay up constantly, no problem, and continuously pour fire into him without very much results at all.
I understand that this was shadow trap and we were at level nine so everything was scaled dramatically but it seems like he can be beaten if we just do it smartly.
