These plants cluster thickly in muddy marshes, typically growing in a 5-foot-square patch. A single plant is slightly smaller than a human hand, and consists of a mass of dark green leaves from which a single feeding stalk extends. The tip of this stalk contains a small, lancet-like protrusion that can pierce flesh with ease.
Spotting a patch of leechweed before blundering into it requires a DC 17 Knowledge (nature) or DC 22 Perception check. A living creature that comes into contact with a patch of leechweed swiftly learns the source of the plant’s name, as dozens of feeding stalks suddenly stab and slash at any bits of exposed flesh. As soon as a creature is in contact with leechweed, the plant attempts an attack against it with a +9 bonus. The attacks continue at the end of each of the creature’s turns if it doesn’t move away from the plant. On a hit, the plant deals 1d4 points of damage and 1d6 points of bleed damage. Fire kills leechweed, as does holy damage or any magical effect that specifically harms plants (such as blight).
