Welcome to the board,
The templates are guidelines. I think you can add what ever fits to the mantle. The description in YS basically states that you can take what you want: "other options abound. "
Sponsored UnSeelie Magic might encompass mind magic. Although I can't remember where the mantle altered a person's mind. Can you refresh my memory?
Strength
Toughness
Speed
Marked by power
Glamours. (Harry probably doesn't have glamours though)
Would all be parts of the mantle as well. I'm not sure recovery was an actual part of the mantle. I suppose it was but with compels on the high concept to represent the fact that the mantle just numbed pain but didn't actually heal anything.
