  • 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 creature. The swarm can’t regain hit points or gain temporary hit points.


  • Blood Drain. Melee Weapon Attack: +6 to hit, reach 5 ft., one creature. Hit: 15 (6d4) piercing damage, and the stirges attach to the target. While attached, the stirges don’t attack. Instead, at the start of each of the swarm’s turns, the target loses 15 (6d4) hit points due to blood loss. The swarm can detach itself by spending 5 feet of its movement. It does so after it drains 30 hit points of blood from the target or the target dies. A creature, including the target, can use its action to detach the stirges.


Stirge swarms are flocks of the bloodsucking creatures. The individual stirges look like a cross between a bat and a mosquito. It has sharp pincers on its legs that allow it to grab hold of prey. They use their long proboscises to stab and suck their victims dry.
