A mature plant consists of a main vine, about 20 feet long. Smaller vines up to 5 feet long branch off from the main vine about every 6 inches. These small vines bear clusters of leaves, and in late summer they produce bunches of small fruits that resemble wild grapes. The fruit is tough and has a hearty but bitter flavor. Assassin vine berries make a heady wine.
An assassin vine can move about, albeit very slowly, but usually stays put unless it needs to seek prey in a new vicinity.
A subterranean version of the assassin vine grows near hot springs, volcanic vents, and other sources of thermal energy. These plants have thin, wiry stems and gray leaves shot through with silver, brown, and white veins so that they resemble mineral deposits. An assassin vine growing underground usually generates enough offal to support a thriving colony of mushrooms and other fungi, which spring up around the plant and help conceal it.
An assassin vine uses simple tactics:
It lies still until prey comes within reach, then attacks. It uses its entangle ability both to catch prey and to deter counterattacks.
