If you've played some Dota it's actually really easy. Just remember Solo top, jungler, assasin/mage mid, ranged carry + support bottom. Shoot me a message if you have any problems or w/e or wanna know something about a hero
I found the room that spawns 2 bosses after you pick an item.
In fact it doesnt spawns 2 bosses. It spawns 28 bosses in 14 double fights.
I had to fight:

All that for 2 items. You pick a random one between 4 pedestals and then the fight starts. After you finish all bosses, you get a second one.
My fingers hurt.
