Monster: Swarm of Confounding Bats (a holiday creation) (Patreon)

Bats are often associated with Halloween, and Halloween thoughts inspired today's D&D creation.

These bats are much like a regular swarm of bats in the game, though the swarm is larger. These particular bats also sow confusion in the minds of their prey (and in the minds of any other creatures nearby).

These bats make use of the delusional condition.
