Swarm Immunities

Source Alien Archive 2 pg. 153, Alien Archive pg. 157
Swarms are immune to the following effects, unless the effect specifies it works against swarms.
  • Bleeding, critical hits, flat-footed, off-target, pinned, prone, staggered, and stunned.
  • Combat maneuvers—swarms can’t be affected by and can’t perform combat maneuvers, unless the swarm’s description says otherwise.
  • Flanking—swarms are unflankable.
  • Dying—a swarm reduced to 0 Hit Points breaks up and ceases to exist as a swarm, though individual members of it might survive.
