I have been ignoring Vicar Amelia for some time as I went to Old Yharnam and Hemwick Charnel Lane instead. I have opened both locked gates in Cathedral Ward, allowing me to summon Henriett:
However, I have heard rumours she vanishes after defeating the Witch Of Hemwick.
Is there any truth to the matter?
I do know I need Insight to summon her (I currently have 12 before the Witch of Hemwick boss fight) and have a few Madman's Knowledge stashed just in case…
