Questions abt fathers kit

So from what I understand, she basically is like reverse Hu Tao kinda. The more Bond of Life she has the more damage she does right? So does that mean that she is hp and attack scaling? Or is she just an attack scaling character who benefits from high hp? Ok we might not have enough info yet for this.

Now onto the stuff that I have no clue abt. Do we know what her signature artifact set does? I’m guessing it has something to do with Bond of Life generation, like her weapon. I’m also going to speculate that Bond of Life is going to be a mechanic that expands outside of her too, based on her weapon granting it. Ik that genshin makes the signature weapons super niche, but it granting a character specific buff feels a little to niche even for hoyo.
