Poison Vigilante Food Supply

Journal
''I told Alberic about the wolf spider venom potion and Phineas tasking me with pouring it on the elven food supply. As a bit of fun retaliation, Alberic asked me to instead pour the poison on the vigilantes' food supply. It'll make them sick, but not kill them. How could I refuse such fun and merriment? Even funnier, if I somehow lose the poison I have, I bet I could mention "poison" to Phineas and he'd give me a replacement!''
