From publisher blurb:
MAGIC: A MANUAL OF MYSTIC SECRETS
"... Before you run off after that Horror you ought to summon a fire spirit and trap it in your sword. That'll give ol' pus-face something to think about ..."
"Of course it can be done. Enchanting your own magic item takes almost as much time and effort as rescuing one from an old kaer and finding out what makes it hum, but making it yourself is a bit less dangerous than adventuring. I suppose you didn't know you could design your own spells either, or travel to the netherworlds? Are you sure you didn't exaggerate about how long you've been studying your Discipline? Well, sit down son, because there's a lot I can teach you about how to use magic. Just try to be worthy of the lessons, because you'll pay the cost one way or another ..."
