Swarm Immunities
Passive Ability
Most swarms are many creatures and rolled up into a single statblock to simply game mechanics. Therefore they are immune to most 1v1 tactics. This does not include any base passive resistances/immunities a swarm might possess inherit to its base creature.
AOE spells or abilities that cover the swarm still can work, and contesting rolls can still be rolled against the swarm. The GM can manually add the status effect..
