Devil's Snare

Devil's Snare was a magical plant with the ability to constrict or strangle anything in its surrounding environment or something that happened to touch it. Devil's Snare did not seem to be common, but certain Herbologists had access to it. Devil's Snare was composed of a mass of soft, springy tendrils and vines that possessed some sense of touch. This plant used its creepers and tendrils to ensnare anyone who touched it, binding their arms and legs and eventually choking them. Struggling or resistance to Devil's Snare would cause the plant to exert a greater force of constriction; the harder a person struggled against Devil's Snare, the faster and more tightly it bound them. However, if the victim was able to maintain their presence of mind and relax, the Snare would relax its grip on them. Devil's Snare preferred a dark, damp environment. It would stop its movement in the environment in front of bright light and would recoil away from the heat of fire, so a well-placed fire or light based spell such as the Bluebell Flames, Fire-Making Spell, Wand-Lighting Charm or Sunlight Charm would effectively drive it away from its victims.The deadly Devil's Snare beared a strong resemblance to the harmless plant, Flitterbloom.
