how exactly do you get to the beast bossfight

[Tea]

im real confused about the paths all i heard is you need a secret polaroid room for the beast

beat mother to unlock it
kill mom in depths 2, take either polaroid or negative, teleport out of the room, open the strange door in the spawn room of depths 2, get dad's note, do the ascent, beat dogma, beat the 4 mega horsemen, beat the beast

in depths 2 now there's always a marked skull that if you bomb it, it will give you the fool card(the skull has a tiny x so keep an eye on that). also if you leave a trinket on a boss room, when you comeback to it on the ascent part it would be turned into a cracked red key for you to unlock the tainted version of the character you are playing
