Easy boss.

What is it with Yuri, and being the embodiment of “an unavoidable fate” like Ryoji from Persona 3

This boss is meant for solo only. Teaming up will just make it harder and tedious. For weapon choice, imo Defiler (Harrow's normal drop) is the best for damage buffed phrase. Long weapon is Ruin for shooting roots in the realm. Save 5 charges on the Defiler, once you get out from the realm, alt shoot the boss. When the charges run out, each normal shot recharge the Defiler once. So you could simultaneously Alt shoot and normal shoot the boss. When its chest opens up, use ruin the waste the boss by zooming in and spray on its head.

Tried team with 3, the dreamer buff only one person at a time. Most of it i was dodging the fireballs and almost fell asleep.

If you stay long enough in the void realm bosses start spawning. Had shroud spawn

Absolutely one of the most annoying, tedious and worst designed boss fights in the game. His 2nd phase is atrocious, you do barely any damage co-op, even with 10 stacks you need to go in that*****ty void world TWICE to take down a health bar. The add spawns are even worse in this fight, than most other fights, and thats saying something.

Boss is easy if you use Swarm mode against him.

A fast firing weapon like the assault rifle or smg is recommended. A single shot or shotgun will do no good, because after you got the buff in the void, every bullet deals the same damage, regardless of per hit dmg. My strategy was: Drink Bloodwart while getting ported to the void. Run to the exit portal and kill 10 enemies on the way (buff indicator bottom right). Exit the void use "hot shot" mod with assault rifle (+10) and fire away. Repeat 1 time and boss was down.

So i was playing Dreamer/Nightmare today and...... well.... in second phase (Nightmare) i killed a lot of adds in the dimension after teleport and saw another boss hp bar pop up?? It said Gorefist, so i focused all adds and got Gorefist as well. I had 25 stacks of dmg buff and tried to kill some more adds, seems like 25 is max. Got out and did enormous amount of dmg, got teleported a second time. Tried to do the same tactic again BUT this time Shroud spawned. I have not tried yet because the boss for some reason bugged out and did not teleport anyone in about 5-7 min so i quit. What if u can spawn, i would not dare to say all the bosses but some before killing Nightmare and get some alternative ending with alternative reward? Maybe someone can confirm?
