Centipede Poison. The first time a character takes damage from a centipede nest, the character must make a successful DC 11 Con saving throw. On a successful save, the character is immune to the poison from that swarm. On a failed save, the character becomes paralyzed. A paralyzed character repeats the saving throw at the end of each of its turns; on a successful save, the paralysis ends and the character becomes poisoned instead. The character remains poisoned for 5 minutes.

Swarm. The swarming nest can occupy another creature's space and vice versa. The swarm can move through an opening large enough for an individual Tiny insect. The swarm can't regain hit points or gain temporary hit points. Once a character takes damage from a centipede nest, the centipedes are on him or her, and the character continues taking 1 piercing damage every round at the start of the centipede nest’s turn, even if the character moves away from the swarm. This continues until three actions have been spent smashing, sweeping, and plucking off all the centipedes that crawled onto the character.

Details

These centipedes aren’t larger or hungrier than any other, normal centipedes; there are just more of them.

A nesting of centipedes is a vast collection of normal centipedes, often combined with a few other sorts of bugs that share the same living space: cockroaches and spiders, generally. Such vermin are not dangerous individually, but when a great number of them are disturbed at once they can present a serious threat.

A party will normally encounter a nest of centipedes by accidentally disturbing the nest itself. Moving large wooden beams and prying into ancient masonry entail the risk of arousing one of these huge colonies. The centipedes can swarm up through the floor or drop from the ceiling. When they attack, they clamber all over the character from head to toe, even getting inside the person’s armor and clothing.
