- "A strange plant which, when pulled from the earth, emits a scream that drives all who hear it mad. Contains a deadly poison."

A Mandrake is a mystical plant whose poison can knock out consumers when ingested orally; its poison is known to be effective against Earthlings, Expellians, Fellpool, Nedians, Tetrageniots, and whatever race of people the mysterious Welch Vineyard belongs to. It is an orange, carrot-like root, though shaped in a vaguely humanoid shape and grows commonly across both Expel and Energy Nede. Its poisonous properties can be tamed and shaped by individuals through the practice of Compounding.
The Mandrake is categorized as a Single-Use Item and a Material; it instantly incapacitates the user when utilized.
