Steal someones and leave them a card that says<br />
"Bet you didn't read that coming" :)
It depends on which way you practice.
You are supposed to fashion them from the souls of the undead.
I've heard they have to be a gift, but you can always drag someone into the shop with you and tilt knowingly with your head......right at the pack you want........over and over. Just a thought.
Never use or have.
I'm sure the only way to get them is to buy them.
Don't think it matters
