So as I was waiting to recieve my epic emperor costume and godlike powers from the amulet of kings at Molag Bals Castle of pain, the quest bugged and I didn't receive any epic powers, not even a shiny emperor costume!
First I thought about restarting the quest, so I could fight through the hordes of deadra as was intended, by one shot killing all of them.
But then I thought: Why not give it a go without the insane buffs and see how I do against the forces of Molag Bal on my own.
And that is exactly what I did

Killing the enemies wasn't too much of a challenge, but I did die once against one of the fireballs Molag Bal flings at you which hit me for 28980 damage or something stupid like that.
Proof of me having 0 Akatosh powers or costume:

Luckily I was able to use the powers of Akatosh to build the bridge and destroy the walls, if not, my adventure would have ended pretty fast.
When I arrived at the big man himself, I got lifted up as usual and I sacrificed my non-existent powers to turn him to stone.
But now the real fight started

I now haf to kill Molag Bal without the damage buff or the defense buffs. His auto attacks hit for half of my health (8000+)
I dodged all his jumps and fireballs so I didn't get to find out how hard they would have hit.
Me with the big dude (again without the buffs):

I won (without dying) and I admit being pretty proud of myself afterwards.
It was a ton of fun doing it without the buffs and having a boss in front of you that can actually kill you makes it a lot more interesting.
Just wanted to share my victory with you guys. Please let me know if this has ever happend to any of you aswell and what you thought of it
