Knight of Hope makes people's wishes come true, idk. what powers could they even have? wish granting? power augementation depending on how much they believe in themselves or others believe in them? making weapons that can be a strong as they believe it is? what are your thoughts?

They really would sort of grant wishes though- Serving Hope to others, just kinda giving them exactly what they were hoping for, what they need, as well as Serving them Hope- Reassuring them things are going to go just fine. And Serving through Hope, sounds like the most Righteous kind of Knight.
