The Strangleweed is a slow moving plant that sustains itself by capturing and crushing its prey, depositing their remains near its roots as fertilizer. While it generally remains stationary, it will venture out in search of new prey when necessary. During late summer, these secondary vines produce small fruit clusters resembling wild grapes, which have a tough texture and a bitter flavor.

In addition to the above-ground variant, there is also a subterranean variety that can be found near sources of heat such as hot springs and volcanic vents. An underground assassin vine generates enough waste to support a thriving colony of mushrooms and fungi that grow around it and help conceal it.
