All magic items have magic, therefore an aura of magic. How is a 'point of origin' intrinsic in an effect of multiple creatures? You just assume there is a point of origin, I want you to back up this assumption.Hypersmurf said:What does 'need' have to do with it?
It has an Effect. Where the Effect begins is the point of origin.
It's like asking "Why does a magic item need an aura?" It's not that it needs one; it just has one.
