Are you using any glitches at all? If so, which ones and in which game? Or do you know of any interesting ones that you haven't tried (yet)?

The image is a humorous rendering of the Gate Skip in Bloodborne. A notoriously finicky glitch which uses the wolfs grab to phase through the gate at the start by the clinic. This grants early access to the back and the forest.
the hunter in research hall can be coaxed to jump if you shoot at him.form the floor above. (From the side not connected by the stairs)
I'm gonna try that in my next playthrough. What I did try with him, is yeet him of with Beast Roar. You can have so much fun especially in the Research Hall with Beast Roar.
The Death Rite Bird in the mountaintops seems to be cheesable(?) with that cliff; haven't done it my self but found this short tutorial.
