Quiting because of burning monolith.

I had 2 tries worth of mats and bout 3 more to try and figure out this damn fight. I watched youtube videos of the fight before hand and figured, this doesn't look to hard. I died 1 time to the Circles of fire after he jumped around. I died 29 times to the flame wall that is IMFUCKINGPOSSIBLE TO FUCKING SEE. I tried every setting on my xbox then raised and lowered my monitors brightness and contrast and FUCKING NOTHING. Then did it once on PC and killed it........it was clearly visible... WTF is going on
