Bites: Melee Weapon Attack: +4 to hit, reach 0 ft., one target in the swarm’s space. Hit: 14 (4d6) piercing damage, or 7 (2d6) piercing damage if the swarm has half of its hit points or fewer. The target must make a DC 10 Constitution saving throw, taking 7 (2d6) poison damage on a failed save, or half as much damage on a successful one.

  • Keen Smell: The swarm has advantage on Wisdom (Perception) checks that rely on smell.
  • 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.
  • Disease Carriers: Any creature bitten by the swarm must succeed on a DC 10 Constitution saving throw or contract a disease. Until the disease is cured, the target can’t regain hit points except by magical means, and the target’s hit point maximum decreases by 7 (2d6) every 24 hours. If the target’s hit point maximum drops to 0 as a result of this disease, the target dies.
