Locusta’s Vials

Origins
Locusta was an ancient Roman woman who was known to supply poisons for emperors. She supplied poison for Nero to murder Emperor Brittanicus and supposedly gave poison to Agrippina the Younger to kill her husband Cladius.

Effects
When any combination of ingredients is mixed in a vial, they form a compound that is poisonous only to the intended victim. The victim will suffer seizures of increasing intensity until death.
