No offense meant towards you, Chleo, but I really don't feel like a disclaimer should piggyback a certain kind of post every time it pops up. It's better to simply write about glamor and direct peoples' attention towards it if they want to properly learn it. Glamor is a kind of magic that people will notice right away if it doesn't physically alter their appearence when they want them to.
As for the spell, it's as simple as charging a bracelet to activate a certain subtle something when it is worn and deactivate when it isn't worn. How people go about the spell is up to them, though I am curious why Garret wants people to come to them for the spell instead of just posting it here.
