You want to solo farm trash epicssssss? *blink blink*
TO answer the question, yes there is trash epics, not much information on it, when you enter the raid you will see trash infront, left and right
The other trash you will probebly have to kill the bosses in order to access those rooms, dont know if this is 100 % sure since i have not tested that theory but yeah, first room there is lots of trash around!
I haven't failed, I've found 10,000 ways that don't work.
