I don't think there has ever been an instance of this node being on a dimensional being so far so I'm not sure if people know the answer themselves. Please correct me if I'm wrong as I'm interested to see how this interaction would work as well.
this is a great question. I haven't jumped into act 6 yet, but I would love to know the answer. and if it hasn't been answered before I run into it, I will let you know.
