So I've been trawling about the web for a while after getting all the available endings in my playthrough.
However, I often hear indirect and vague references to the "dancing wolf" ending, which I looked up and found this. https://www.youtube.com/watch?v=h16QzAkChMg
From what I gathered, it requires a special set of circumstances that need to be met, as well as playing on a specific version of the unofficial patch plus, initiating the ending sequence with low humanity and an amount of other unverifiable various actions as well as going with any ending that lets you slash LaCroix's throat, and doing so; upon which the special dialogue option appears.
I ask this here, if anyone is able to provide with me a list of the most basic requirements to achieve this ending. Thanks in advance.
