Dear Madam Avarscanti,
I have a wonderful light tower shield for sale, it weighs approximately 15 pounds, which is roughly the equivalent of a large shield. I also have another shield - a large shield - that is moderately enchanted with a spell that will allow you immunity to magic missiles, as well as creating a force barrier around your person.
My asking price is 1,000 coins, and for that I shall give to you both shields. I would be happy to discuss things further with you in person, as well as show them to you. You may locate me at the Last Stand.
Signed, 'Mother' Agnes Valenti
