Blender to Daz? Trying to rig new body parts

unsuccessfulpacifist

So I'm hoping to make something like the sort of... face tendrils that go down to the front of the shoulders like in the picture below. I was thinking I'd model them in blender, but I'm not sure how to create bones for rigging them so that they can be posed corrently? I've looked into tutorials but most of them are for the models themselves, not an addition like this.

Any help would be super super appreciated! Thanks so much!
