HARD MODE ITEMLESS Isaac vs. THE BEAST

no fancy editing at the end cause most of my deaths stayed on my old pc :/.
heres a QnA
1. Why is Ultra Death of all bosses in the thumbnail?
A: In my opinion he's the most unfair boss out of all the bosses due to the scythe attack of his occasionally not leaving any dodging space, leading to unavoidable damage (luckily I made my way out of them undamaged in this attempt!)
2. Why?
A: I was bored
3. But Dogma is an item!
A: Dogma is a story item and even if I deleted the item, I would still get the perk of 6 hearts and a mantle, therefore I do not count it as an item. That's like counting polaroid as an item and trying to go to the chest itemless.
4. Why mention hard mode in the title? Doesn't it not affect boss fights?
A: There's a special case for the beast where the Dogma item will give you a wafer *specifically in normal mode*, so by playing on hard mode, the fight is technically 2x harder.
