Mantrap

A mantrap is a giant carnivorous plant that resembles an oversized flytrap. To attract prey, the mantrap releases a pollen that magically draws creatures to it. Though it will snap its leafy jaws shut around any warm-blooded creature that strays within its reach, it prefers humanoid prey.

Loot.

• 1d4 Vials of Mantrap Pollen (As an action, this vial can be opened and waved in the air, filling a 5-foot cube with Mantrap Pollen. Any beast or humanoid within 30 feet of the cube must succeed on a DC 11 Wisdom saving throw or be forced to use all of their movement on their turn to get as close to the cube as possible. An affected creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.)
