Ingredients: Pigeon blood, wax, dog blood.
Process: The letter writer, who need not be the sorcerer, pens a missive in pigeon blood and clearly addresses the recipient. The sorcerer then melts wax and mixes it with dog’s blood to seal the letter.
System: The sorcerer makes the Ritual roll when anyone other than the recipient opens the letter. The victim suffers one point of Aggravated Health damage if the caster wins the Ritual roll, or three points of Aggravated damage on a critical win, and the letter destroys itself in a burst of flame. Once the Letter Ward is triggered, anyone wanting to open the letter must roll Stamina + Resolve at Difficulty 4 for a normal Ward, or Difficulty 7 for a critical-success Ward.
