Mandrake by DracoAwesomeness on DeviantArt

The mandrake gives voice to an unsettling shriek. All creatures within a 30-foot radius of a shrieking mandrake must succeed on a DC 15 Wisdom saving throw or become poisoned.. The mandrake remains dormant for one year, after which time it grows into a thick, tuberous root that is shaped like a young humanoid sprouting a thick, leafy head of hair. If the root is pulled from the ground, it wails with such piercing fury that most common folk who hear it die instantly. Medicinal Marvel.

Complete description and statblock for Mandrake compatible with D&D 5th edition.. The mandrake magically turns invisible until it attacks, or until its concentration ends (as if concentrating on a spell). Any equipment the mandrake wears or carries is invisible with it.
