Special Abilities

Cling (Ex) Each creature that takes damage from a dredger troop’s troop attack must succeed at a DC 13 Reflex save or gain the flat-footed and off-target conditions until the end of the troop’s next turn as dredgers cling to the target’s body, throwing off their aim and balance.

Swarm Mind (Ex) Members of the Swarm are bound together into a singular hive mind by a blend of exuded pheromones, imperceptible movements of antennae and limbs, electrostatic fields, and telepathic communication. All Swarm creatures within 30 feet of each other are in constant communication; if one is aware of a threat, all are. (Such awareness can spread along a “chain” of Swarm creatures under appropriate circumstances, potentially alerting distant Swarm creatures). In addition, once per round when within 30 feet of another Swarm creature, a Swarm creature can roll twice and take the better result on a saving throw against a mind-affecting effect.


Thanks to their hive-mind intelligence, Swarm components organize easily into troop formations, becoming all the deadlier. The above stat block represents a group of dredgers, which are used by the Swarm en masse for digging trenches and burrowing behind enemy lines to cause remarkable amounts of chaos.
