Just me or the spirit healer mind doesn't seem like got any affect from "hero",maybe it's because she only interact with him for a short time or because spirit can protect the user mind from charm (let's call it "charm" for now)
all knowledge i know about charm magic is a few points
1: it stops working if you are aware it is magic
2: someone with a stronger magic potential cannot be affected
3: it is often used in sneaky ways as to not alert suspicion
4: it counts as a mind alteration magic
5: anyone who uses it is a giant bastard who will always use it for their own gain and their own gain only
6: if a person is using charm magic just seeing this person for a second will already affect you (unless point 1 or 2 is in effect)
