so i was playing a Mother route
get both of knife pieces and killed Mines II boss
when i tried to get damaged by the door to Mausoleum it didn't worked
after a while i remembered that Sigil of Asmodeus block spikes damage so i turned on the console in another run i gave me the Sigil
as i supposed it didn't open again
i removes it and it opened
i don't know if that was un purpose but i guess is not
