Swarms of many tiny insects that may be encountered protecting their nest. May also be drawn to light or unusual smells.

• Type and locomotion: A swarm may be composed of creepers (e.g. spiders, ants, centipedes) or flyers (e.g. bees, hornets). Some swarms are capable of both types of movement (e.g. beetles, locusts).
• Size: 10’ × 30’ area, typically.
• Immunity: Only harmed by fire, extreme cold, sleep spells (affect the whole swarm), smoke (drives off), or other attacks as the referee wishes.
• Swarm attack: Automatically damages characters within swarm area: 2hp if wearing armour, 4hp without.
• Warding off: Characters inside the swarm who defend themselves by brandishing a weapon (or similar) suffer half damage from the swarm. A brandished torch damages the swarm.
• Escaping: On exiting the swarm, characters continue to suffer half damage until 3 rounds are spent swatting the attached insects.
• Diving into water: Suffer damage for one round, then attached insects drown.
• Pursuit: An angry (i.e. damaged) swarm will pursue characters until they are out of sight or inaccessible.
