Heir of hope.... would they be able to literally turn into hope? Like, become a golden light and shine onto their fellow players, to give them an inner Hope and power? Would they be able to see the filaments of hope surrounding everyone, or is that based for a different class? Could a Heir Inspire Hope into their fellow players?

It’s hard to say because Hope is a God Damn Difficult to Grasp Concept. So materializing it like that, with Hopey Ropes or a Golden Light, it’s hard to actually tell. If you think that’s how it’d work, it likely works like that. The Page or Knight may be better giving Hope, but a Heir and Witch could certainly inspire Hope in others.
