The Swarm is a group of small insects that act as a single enemy unit in Remixed Dungeon. It's an unusual mob that splits into multiple smaller swarms when defeated.
A Swarm consists of dozens of small insects that appear as a single creature but function differently from typical mobs. The Swarm is immune to most status effects due to its nature as a collection of small creatures. According to the game description, “The deadly swarm of flies buzzes angrily. Every non-magical attack will split it into two smaller but equally dangerous swarms.”
