Timed challenges were by far the most stressful experience out of all endgame content. With reduced damage to demons the only hope to get gold rating was BFC ammo.
I play on Nightmare with cranked sliders. And for the Henchman the main difficulty was to endure long phases due to him being a bullet sponge (basically, "shoot at him till he dies"). No actual learning the fight.
Marok, on the other hand was somewhat tricky. Kinda reminded me of Prince Asscrack fights (parially mixed with Kreed). Funnily enough, I haven't experienced much problem with any of Asscrack fights. This maybe somehow connected with Spear and Shield having different parry timings, so Marok fast flurry attacks are harder to adapt to using Spear with it's slower windup animation.
I also had harder time Spear vs Shield parrying some non-boss demons (Agaddon Brute, Cosmic Baron, sometimes even Cyberdemon).
However, Spear is cool anyway and I use it 95% of the time (Tormentor my beloved).
Two of them placed in the opposite corners especially.
Should I purchase DLC separately or I need Premium Edition which includes base game as well? Base game was completed on Gamepass via Xbox Cloud gaming.
