Defiled Yoshiro is Cursed Soh.

Cursed Soh is Defiled Yoshiro. Defiled Yoshiro is Cursed Soh.

 I've mentioned this many times. 

The Defiled Yoshiro in question is Soh when she was the previous Maiden.

But it's better to say the all the defiled Yoshiros have become Cursed Soh. Cursed Soh is alike to a defiled Goddess, born after 7 generations. She's got 6 Yoshiro spirits with her.

I'm bringing this up because I was replaying Bloodborne and there's a 'Cursed and Defiled Chalice Dungeon.' But in the second description, its only called a defiled dungeon but the description says it's cursed.

So these two seem to be the same thing... Or did they leave it out because it's implied that the defiled dungeon must be cursed as well?

I just thought it was interesting.
