Traits

Echolocation. The swarm can’t use its blindsight while deafened.

Keen Hearing. The swarm has advantage on Wisdom (Perception) checks that rely on hearing.

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

Actions

Vampire bats fly in a tight formation (a swarm that fills a cube of space about 5 feet on each side) slashing with their nasty fangs, and licking up blood of their prey.  A creature takes 4d4 slashing damage when it enters the swarm’s area for the first time on a turn or starts its turn there. 

 

Description

This creature is basically a living version of the 2nd level spell "Cloud of Daggers"  married with the swarm of bats stat block.  Note there is no save or attack roll, victims take 4d4 slashing if they start their turn in the swarm, or move into the swarm.  Good for pushing characters to keep moving, or creating dangerous areas that are unsafe to rest.  Excellent for Curse of Strahd campaigns. 

"Then, from out of the blackness, a sound rises—a whisper at first, then a frantic, leathery rustling, like dry leaves caught in a violent storm. A cloud of shifting, writhing shadows surges forward, Dozens of small, beady red eyes gleam and tiny fangs glisten as shrill, piercing screeches rip through the air. You are left with a chilling realization— They are not here to feed. 

They are here to drain you dry."
