ok so, im in the depths i got a low dmg quad shot run, no biggie prob gona lose the fight
earlier i had found quoad from this secret trapdoor that you sometimes find under rocks and stuff
i had found them before so i knew to put my stompylegs to use that i had gotten all the way back from basement
so back to the depths. looking p grim
i clear out a monstro 2 room and start clearing the rocks around and i get another trapdoor
i take it in hopes of receiving a sweet item
but theres no item, the room goes off to the next screen where there is a double wide room
with a trap door down (bug early in the original game) and 4 deal with the devil items
i grab the items play the devil deals and go down the trapdoor

"THE DARKROOM"

and i got gubby (again ofcrs)

im not gona spoil the floor enemies and the boss but i shreked trough the boss in 3-4 shots of quad gubby power!
tl;dr chest like floor under sheol
