special_abilitiesname: Devilâs Sight,desc: Magical darkness doesnât impede the infernal swarmâs darkvision,name: Magic Resistance,desc: The infernal swarm has advantage on saving throws against spells and other magical effects.,name: Shaped Swarm,desc: As a bonus action, the swarm can shape itself into a Huge fiend or back into a shapeless mass. Its statistics are the same in each form, and it canât regain hp or gain temporary hp. If a creature is more than 10 feet away from the infernal swarm, it must take an action to visually inspect the fiend form and succeed on a DC 25 Intelligence (Investigation) check to discern the Huge fiend is actually a swarm of Small insects. A creature within 10 feet of the swarm immediately discerns the truth. While in fiend form, it can wield weapons and hold, grasp, push, pull, or interact with objects that might otherwise require a more humanoid form to accomplish. If the infernal swarm takes thunder damage while in its fiend form, it immediately changes to its shapeless form. While in shapeless form, it can occupy another creatureâs space and vice versa and can move through any opening large enough for a Small fiend, but it canât grapple or be grappled.
