Special Traits

• Keen Smell. The swarm has advantage on Wisdom (Perception) checks that rely on smell.
• Poison and Disease Resistance. The swarm has advantage on saving throws made to resist disease and the poisoned condition.
• Swarm. The swarm can occupy another creature’s space, and vice versa, and the swarm can move through any opening large enough for a Tiny rat. The swarm can’t regain hit points or gain temporary hit points.
• Swarm Insensitivity. If damage reduces the swarm to 17 or fewer hit points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is from a critical hit. On a success, the swarm is only reduced to 18 hit points. If damage reduces the swarm to 0 hit points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is from a critical hit. On a success, the swarm drops to 1 hit point instead.

Actions

• Bites. Melee Weapon Attack: +2 to hit, reach 0 ft., one target in the swarm’s space. Hit: 7 (2d6) piercing damage, or 3 (1d6) piercing damage if the swarm has half of its hit points or fewer. Additionally, living creatures must succeed on a DC 10 Constitution saving throw, or take 9 (2d8) necrotic damage and contract the zombie necrosis disease (p.192).
