Poisoner's Revenge

A potion to infuse a poison property into leather armor. Once created, the potion is good for 30 days, but once opened must be used within seven days. Once per day, for seven days, it users must measure out the appropriate amount of the potion into a small bowl, add three drops of their own blood, and then while saying the correct words paint the appropriate markings on the jerkin and pants. This process takes one hour.
